NEW QUESTION # 28
An administrator has configured NDB HA across multiple Nutanix clusters.
Which failure scenario will require manual interaction for the recovery?

  • A. More than one HA proxy VM is down.
  • B. More than one API Server VM is down.
  • C. NDB Server process is down.
  • D. One repository VM is down.

Answer: B

Explanation:
NDB HA is a feature that provides high availability and resilience for the NDB service and its components.
NDB HA creates a cluster of API server VMs, repository VMs, and HAProxy VMs across multiple Nutanix clusters. Each component has a leader and a set of followers that are synchronized and can take over the leader role in case of a failure. NDB HA also monitors the health and status of the NDB components and performs automatic failover and recovery actions when possible. However, some failure scenarios may require manual intervention from the administrator to restore the NDB service. One such scenario is when more than one API server VM is down. The API server VMs are responsible for handling the requests from the NDB UI and CLI, as well as communicating with the repository VMs and the HAProxy VMs. If more than one API server VM is down, the NDB service may become unavailable or unstable, and the administrator will need to manually restart or redeploy the affected API server VMs. The other options do not require manual interaction for the recovery, as NDB HA can handle them automatically. If one repository VM is down, NDB HA will fail over to another repository VM that has the latest data. If more than one HAProxy VM is down, NDB HA will route the traffic to the remaining HAProxy VMs. If the NDB server process is down, NDB HA will restart the process or fail over to another API server VM.

NEW QUESTION # 29
Which two encryption methods can be used when configuring an SMTP server? (Choose two.)

  • A. TLS
  • B. S/MIME
  • C. SSL
  • D. IPsec

Answer: A,C

Explanation:
NDB supports SMTP server configuration for sending email notifications and alerts. SMTP server configuration requires specifying the SMTP server address, port, username, password, and encryption method.
The encryption method determines how the email messages are secured during transmission. NDB supports two encryption methods for SMTP server configuration: TLS and SSL.
TLS (Transport Layer Security) is a protocol that encrypts and authenticates data between the email client and the SMTP server. TLS can operate in two modes: explicit and implicit. In explicit mode, the email client and the SMTP server negotiate the encryption method and parameters after establishing a plain text connection.
This mode typically uses port 587. In implicit mode, the email client and the SMTP server assume that the connection is encrypted from the start, without any negotiation. This mode typically uses port 465.
SSL (Secure Sockets Layer) is a predecessor of TLS that also encrypts and authenticates data between the email client and the SMTP server. SSL operates in implicit mode only, and uses port 465 by default. SSL is less secure than TLS, but it is still widely used and supported by many email providers.
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard that encrypts and signs email messages at the application layer, rather than the transport layer. S/MIME requires the use of digital certificates and public key cryptography to ensure the confidentiality and integrity of email messages. S/MIME is not a valid encryption method for SMTP server configuration, as it does not affect the connection between the email client and the SMTP server.
IPsec (Internet Protocol Security) is a suite of protocols that secures IP packets at the network layer, rather than the application or transport layer. IPsec can encrypt and authenticate data between any two IP endpoints, such as routers, firewalls, or hosts. IPsec is not a valid encryption method for SMTP server configuration, as it does not apply to the specific protocol or port used by SMTP.

NEW QUESTION # 30
An administrator has been tasked with restoring an Oracle database that has recently failed. The administrator must restore the database to the prior day's state.
Which two restore options could be used? (Choose two.)

  • A. Point in Time
  • B. Most Recent Time Available
  • C. Tail Logs Backup
  • D. Snapshot

Answer: A,D

Explanation:
The correct answer is B and D because they are the two restore options that can be used to restore an Oracle database to the prior day's state using Nutanix Era. A snapshot is a point-in-time copy of a database that is stored in the Era Time Machine, which is a distributed file system that collects logs and snapshots from databases. A point in time is a specific moment in time within the retention period of the SLA policy that is applied to the database. By using either of these options, the administrator can select the snapshot or the point in time that corresponds to the prior day's state and restore the database from it. The other options are not correct because they are not restore options that are available in Nutanix Era. Option A is not correct because Most Recent Time Available is not a restore option, but a clone option that creates a clone of the database from the most recent snapshot or log backup. Option C is not correct because Tail Logs Backup is not a restore option, but a backup option that captures thetransaction logs of the database that have not been backed up by the SLA policy.

NEW QUESTION # 31
A request is received to refresh a database clone from a new manual snapshot. When the administrator attempts to create the new snapshot from the Time Machine, it is in a Frozen state.
What causes a Time Machine to enter the Frozen state and what are the administrator's options to complete the request?

  • A. Cause: The Time Machine enters a Frozen state after too many snapshot or log catchup failures.Resolution: Remediate the snapshot or log catchup failures, this thaws the Time Machine, allowing normal operations to continue and the request can be completed.
  • B. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
    Resolution: To complete the request the database must be re-registered in NDB, this thaws the Time Machine and it resumes operation so the clone can be refreshed.
  • C. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
    Resolution: To complete the request the database must be re-registered in NDB, create a new Time Machine and create a new clone.
  • D. Cause: The Time Machine enters a Frozen state when the database is de-registered without removing the Time Machine.
    Resolution: The Time Machine must be paused, then the database re-registered with a new Time Machine and a new clone created.

Answer: B

Explanation:
A Time Machine is a core construct of the copy data management service in NDB that captures and manages the data of a database to deliver a recovery point objective (RPO) SLA. A Time Machine can enter a Frozen state for various reasons, such as database de-registration, snapshot or log catchup failures, or manual intervention.When a Time Machine is in a Frozen state, it stops taking new snapshots and log backups, and cannot perform any clone, refresh, or restore operations. To resume the normal operation of a Time Machine, it must be thawed by resolving the root cause of the freeze. One of the common causes of a Time Machine freeze is when the database is de-registered from NDB without removing the Time Machine. This can happen when the administrator wants to move the database to a different NDB instance or cluster, or when the database is accidentally de-registered. In this case, the Time Machine becomes orphaned and frozen, and cannot be used for any operations. To complete the request to refresh a database clone from a new manual snapshot, the administrator must first re-register the database in NDB using the same database name and ID as before. This will automatically thaw the Time Machine and resume its operation. The administrator can then create a new manual snapshot from the Time Machine and use it to refresh the database clone. The other options are not correct, as they either require unnecessary steps or do not address the root cause of the freeze. References:

NEW QUESTION # 32
When trying to restore a database via Time Machine (TM), the option to restore data to a Point in Time is not available.
What should the administrator do to enable Point in Time Recovery?

  • A. Use an SLA that supports Continuous Log retention.
  • B. Take a Manual snapshot and use it for DB recovery.
  • C. Use Brass SLA & update the Log catch up frequency.
  • D. Update the TM schedule to perform DB Log catch up.

Answer: A

Explanation:
Point in Time Recovery (PITR) is a feature of NDB that allows restoring a database to any point in time within the retention period of the SLA. To enable PITR, the SLA must support Continuous Log retention, which means that NDB captures and stores the database logs continuously. This allows NDB to replay the logs from the last snapshot to the desired point in time during the restore process. The other options do not enable PITR, but rather affect the frequency and timing of the snapshots and log catch up operations.

NEW QUESTION # 33
An administrator needs to restore a source database from a snapshot. The database shares the source volume with multiple other databases.
How does NDB handle this database restore operation?

  • A. Replaces the source volume with the snapshot volume
  • B. Copies the specific database files to the source volume
  • C. Copies all database files to the source volume
  • D. Replaces source volume with specific db disks

Answer: B

Explanation:
The correct answer is A because NDB handles the database restore operation by copying the specific database files from the snapshot volume to the source volume, without affecting the other databases that share the same source volume. NDB uses a copy-on-write mechanism to create snapshots and clones, which means that only the changes made to the database files are stored in the snapshot or clone volume, while the original files are kept in the source volume. Therefore, when restoring a source database from a snapshot, NDB only needs to copy the specific database files that have been modified since the snapshot was taken, and overwrite them on the source volume. The other options are not correct because they either cause data loss or unnecessary data transfer. Option B is not correct because replacing the source volume with specific db disks would erase the other databases that share the same source volume, which is not desirable. Option C is not correct because replacing the source volume with the snapshot volume would also erase the other databases that share the same source volume, as well as any changes made to the source database after the snapshot was taken, which is not desirable. Option D is not correct because copying all database files to the source volume wouldbe inefficient and unnecessary, as only the modified files need to be copied, and the other files are already present on the source volume.

NEW QUESTION # 34
Refer to the exhibit.

A request is received to provision a new Oracle SIHA DB & VM to test ASMLIB on OEL79 and Oracle 19c.
When walking through the provisioning workflow, only ASMFD is available in the ASM Driver drop down.
What is necessary to provision the requested SIHA DB and DB VM with ASMLIB?

  • A. Update the software profile to include the ASMLIB driver.
  • B. Install ASMLIB on the database server.
  • C. Update the NDB driver config to enable ASMLIB for Oracle.
  • D. Install ASMLIB on the NDB server.

Answer: A

Explanation:
In the context of Nutanix Database Automation (NCP-DB), when provisioning a new Oracle SIHA DB & VM, if only ASMFD is available in the ASM Driver drop-down, it indicates that ASMLIB is not included in the current software profile. To provision the requested SIHA DB and DB VM with ASMLIB, it's essential to update the software profile to include the ASMLIB driver. This action will enable ASMLIB as an option in the ASM Driver drop-down during the provisioning workflow.

NEW QUESTION # 35
An administrator would like to replicate database snapshots to remote Nutanix clusters.
What should the administrator do to manage Time Machine data availability across all registered Nutanix clusters in NDB?

  • A. Update the cluster's Data Access & select the remote cluster.
  • B. Select the snapshots & replicate them to each Nutanix cluster.
  • C. Add Data Access to each Nutanix cluster and assign a DAM policy.
  • D. Update the SLA on the Time Machine & schedule the remote replication.

Answer: C

Explanation:
To replicate database snapshots to remote Nutanix clusters, the administrator needs to add Data Access to each Nutanix cluster and assign a Data Availability Management (DAM) policy. Data Access is a feature of NDB that enables cross-cluster data mobility and protection. A DAM policy defines the replication frequency, retention period, and priority of the database snapshots across the clusters. By adding Data Access to each Nutanix cluster and assigning a DAM policy, the administrator can manage the Time Machine data availability across all registered Nutanix clusters in NDB.

NEW QUESTION # 36
Within NDB, an administrator needs to register a PostgreSQL database server VM with a database.
Where should the database data and log files be located in order to successfully complete this task?

  • A. On the same disk as the binary installation
  • B. On the same mount point
  • C. On the same disk as the operating system
  • D. On a separate mount point

Answer: D

Explanation:
To register a PostgreSQL database server VM with a database on NDB, the database data and log files must be located on a separate mount point from the operating system and the binary installation. This is because NDB uses the mount point as the identifier for the database server VM and the database. If the data and log files are on the same mount point as the operating system or the binary installation, NDB will not be able to recognize them as a valid database server VM or database. Therefore, the administrator should create a separate mount point for the data and log files and specify it during the registration process.

NEW QUESTION # 37
What is the purpose of Data Access Management policies in NDBMulti-Cluster?

  • A. To perform snapshot operations on a single Nutanix cluster
  • B. To manage time machine data availability across all registered Nutanix clusters in NDB
  • C. To remove data accessibility of a time machine across all registered Nutanix clusters in NDB
  • D. To register multiple Nutanix clusters in NDB

Answer: B

Explanation:
Data Access Management (DAM) policies are a feature of NDB Multi-Cluster that allows you to control the access and availability of time machine data across different Nutanix clusters. You can use DAM policies to specify which clusters can access the time machine data of a source database, and which clusters can replicate the time machine data for backup or disaster recovery purposes. DAM policies help you to optimize the storage and network resources, as well as ensure the security and compliance of your database workloads. The purpose of DAM policies is not to register multiple Nutanix clusters in NDB, as this is done by using the Add Cluster option in the NDB settings page. The purpose of DAM policies is also not to perform snapshot operations on a single Nutanix cluster, as this is done by using the Time Machine feature in the NDB dashboard. The purpose of DAM policies is also not to remove data accessibility of a time machine across all registered Nutanix clusters in NDB, as this is done by using the Delete option in the Time Machine page.

NEW QUESTION # 38
Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?

  • A. Third-party backups vendors can continue to backup the archived logs from the database log destination.
    NDB will still be able to capture the logs, considering the log catch-up begins before the logs get backed up
  • B. Third-party backups vendors can continue to backup the binary logs from the binary log location. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get purged.
  • C. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will not be supported, but snapshot-based recovery of the databases is supported.
  • D. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will be supported, but snapshot-based recovery of the databases is not supported.

Answer: A

Explanation:
NDB supports two modes of log backup management for Microsoft SQL databases: NDB-managed and
3rd-party managed. In the NDB-managed mode, NDB takes full control of the log backups and stores them in the Cerebro log location. In the 3rd-party managed mode, NDB allows the use of external backup tools to backup the logs from the database log destination. However, NDB still needs to capture the logs for its own operations, such as point-in-time recovery, clone refresh, and log catch-up. Therefore,NDB will periodically scan the database log destination and copy the logs to the Cerebro log location. This process requires that the log catch-up begins before the logs get backed up by the 3rd-party tool, otherwise NDB will miss some logs and the operations will fail. If the 3rd-party tool grants exclusive access to the logs, then NDB will not be able to capture them at all, and the operations will not be supported. References:

NEW QUESTION # 39
In NDB, which two Time Machine options are available when creating a database clone? {Choose two.)

  • A. Restore point
  • B. Point in time
  • C. Backup
  • D. Snapshot

Answer: B,D

Explanation:
The correct answer is A and D because these are the two Time Machine options that are available when creating a database clone in NDB. Point in time allows the user to specify a date and time to create a clone from a specific point in the database history. Snapshot allows the user to select a previously taken snapshot to create a clone from a consistent state of the database. Option B is incorrect because Restore point is not a Time Machine option, but a feature that allows the user to restore a source database to a previous point in time.
Option C is incorrect because Backup is not a Time Machine option, but a feature that allows the user to backup a database to a remote location.
References: The following sources provide more information about the Time Machine options and cloning features in NDB:

NEW QUESTION # 40
Which NDB feature collects logs and snapshots from databases?

  • A. One-click Patching
  • B. Time Machine
  • C. SLA
  • D. Database Restore

Answer: B

Explanation:
The correct answer is B because the Time Machine feature of NDB collects logs and snapshots from databases and stores them in a distributed file system. The Time Machine enables the administrator to protect, clone, and restore databases using the SLA policies and the NDB UI or API. The Time Machine also manages the replication of database snapshots in an NDB multicluster environment. The other options are not correct because they describe different features or functions of NDB. Option A is not correct because Database Restore is an operation that uses the Time Machine to restore a source database or a clone to a previous point in time. Option C is not correct because SLA is a policy that defines the frequency and retention of database snapshots and logs. Option D is not correct because One-click Patching is a feature that allows the administrator to test, publish, and apply database patches using the NDB UI or API.

NEW QUESTION # 41
For an NDB offline upgrade, which NDB CLI command should be used to upload the upgrade bundle?

  • A. upload upgrade_bundle path=path_to_upgrade_bundle
  • B. path=path_to_upgrade_bundle upgrade bundle
  • C. upgrade upload_bundle path=path_to_upgrade_bundle upload bundle
  • D. path=path_to_upgrade_bundle

Answer: A

Explanation:
For an NDB offline upgrade, you need to download the upgrade bundle from the Nutanix Support Portal and copy it to the NDB server. Then, you need to use the NDB CLI command upload upgrade_bundle with the path parameter to specify the location of the upgrade bundle file. This command will upload the upgrade bundle to the NDB server and verify its integrity. After uploading the upgrade bundle, you can use the upgrade command to perform the upgrade.

NEW QUESTION # 42
Refer to the exhibit.

An administrator is receiving critical NDB email alerts regarding storage for the DBA database, which is a member of a database group.
How would the administrator remediate the issue within NDB?

  • A. From the Database Summary page for the DBA database, use the Scale option to grow the storage accordingly.
  • B. From the Databases page, select the Database group and Scale the storage from the Database Actions menu.
  • C. From the Alerts page, select the alert, choose Set Status to Resolved, and Scale the storage via the Resolve Now dialogue box.
  • D. From Prism Central, add additional storage to the VM, then expand the log storage via the database tools.

Answer: A

Explanation:
The administrator can remediate the issue of critical storage alerts by scaling up the storage directly from the Database Summary page for that specific DBA database. This action allows for an increase in storage capacity to alleviate space constraints and prevent future critical alerts related to storage space1. The other options are not correct, as they either involve scaling the entire database group, which may not be necessary or desired, or require additional steps outside of NDB, which may not be feasible or efficient. References:
* 1: Nutanix Database Automation (NCP-DB) course, Module 2: Database Provisioning, Lesson 2.4:
Database Scaling, slide 5


NEW QUESTION # 43
How does NDB send notifications when alerts are generated?

  • A. SNMP
  • B. Pulse
  • C. Email
  • D. APIs

Answer: C

Explanation:
NDB sends notifications when alerts are generated via email. The email notifications can be configured to send to one or more recipients, and can be customized to include the alert severity, category, description, and resolution steps. The email notifications help to inform the database administrator and other stakeholders about the status and issues of the NDB-managed databases and operations.
NDB does not send notifications via SNMP, APIs, or Pulse. SNMP is a protocol for collecting and organizing information about managed devices on a network. APIs are interfaces for communicating and exchanging data between different applications or systems. Pulse is a feature of the Nutanix cluster that collects and sends diagnostic and usage data to Nutanix for analysis and support.

NEW QUESTION # 44
An administrator needs to provide the least-privilege access to a newly-hired engineer whose task is to add new VLANs or IP Pools in NDB.
Which role should the administrator select to complete this task?

  • A. Infrastructure Administrator
  • B. Database Infrastructure Administrator
  • C. Database Administrator
  • D. Super Administrator

Answer: A

Explanation:
An Infrastructure Administrator is a role in NDB that has the permission to manage network and storage resources, such as VLANs, IP Pools, and Storage Containers. This role is suitable for the engineer who needs to add new VLANs or IP Pools in NDB. The other roles have either more or less privileges than required for this task. A Database Administrator can manage databases and database server VMs, but not network and storage resources. A Super Administrator can manage all aspects of NDB, but this is more than the least-privilege access needed. A Database Infrastructure Administrator can manage both databases and network and storage resources, but this is also more than the least-privilege access needed.

NEW QUESTION # 45
An administrator needs to add a stretched VLAN across two clusters in NDB Which two prerequisites should be met prior to completing this action? (Choose two.)

  • A. VLAN must be static.
  • B. Both clusters must be registered in NDB.
  • C. VLAN must be IPAM.
  • D. Nutanix Cluster Management must be enabled.

Answer: A,B

Explanation:
A stretched VLAN is a virtual network that spans across multiple Nutanix clusters and allows the communication between VMs on different clusters using the same subnet. A stretched VLAN can be used to provide high availability and load balancing for NDB components, such as HAProxy VMs, that require a virtual IP address (VIP) to beaccessible from any cluster. To add a stretched VLAN across two clusters in NDB, the administrator needs to meet two prerequisites: the VLAN must be static and both clusters must be registered in NDB. A static VLAN is a VLAN that is manually created and configured by the administrator, as opposed to an IPAM VLAN that is automatically created and managed by NDB. A static VLAN can be added to a stretched VLAN in NDB, while an IPAM VLAN cannot. Both clusters must be registered in NDB before adding a stretched VLAN, as NDB needs to have the information and access to the clusters and their networks.
The administrator can register the clusters in NDB using the Prism Element details, agent network configuration, and storage container information. The other option, Nutanix Cluster Management, is not a prerequisite for adding a stretched VLAN in NDB. Nutanix Cluster Management is a feature that allows the administrator to manage multiple Nutanix clusters from a single NDB UI, such as creating or deleting clusters, adding or removing nodes, or performing cluster operations. Nutanix Cluster Management is not required for adding a stretched VLAN, as the VLANs are created and configured in Prism Element, not in NDB. References:

NEW QUESTION # 46
Which policies define Time Machine data availability across multiple registered clusters in NDB?

  • A. Service Level Agreements
  • B. Recovery Plans
  • C. Data Access Management
  • D. Data Protection

Answer: B

Explanation:
The recovery plans policy defines the Time Machine data availability across multiple registered clusters in NDB. The recovery plans policy allows the database administrator to specify the source and target clusters, the frequency and retention of the cross-cluster snapshots, and the network and compute profiles for the recovery operations. The recovery plans policy helps to ensure the disaster recovery and business continuity of the NDB-managed databases in case of a cluster failure or outage.
The data access management policy defines the access permissions and roles for the NDB users and groups.
The data access management policy allows the database administrator to grant or revoke access to the NDB instance, the database server VMs, the databases, and the database operations. The data access management policy helps to ensure the security and compliance of the NDB-managed databases and users.
The data protection policy defines the backup and restore settings for the NDB-managed databases. The data protection policy allows the database administrator to specify the frequency, retention, and compression of the database snapshots, and the backup location and encryption for the database backups. The data protection policy helps to ensure the backup and recovery of the NDB-managed databases within the same cluster.
The service level agreements policy defines the performance and availability metrics for the NDB-managed databases. The service level agreements policy allows the database administrator to monitor and enforce the database uptime, latency, throughput, and IOPS. The service level agreements policy helps to ensure the quality of service and performance of the NDB-managed databases.

NEW QUESTION # 47
Which action should be completed before updating Oracle Database software?

  • A. Perform rolling reboots of the Oracle Database VMs.
  • B. Verify the Oracle OS version is supported on AHV.
  • C. Download the PSU from Oracle support.
  • D. Verify CVMs have the required memory allocated.

Answer: C

Explanation:
Before updating Oracle Database software, you need to download the Patch Set Update (PSU) from Oracle support. A PSU is a collection of critical and security patches for Oracle products. You need to have a valid Oracle account and access to the My Oracle Support portal to download the PSU. You also need to check the compatibility and prerequisites of the PSU before applying it to your Oracle Database software. NDB uses out-of-place patching for Oracle, which means you need to create a new software profile version with the patched Oracle software and use it to update your existing databases. References:

NEW QUESTION # 48
A database administrator wants to define initialization variables for different types of database engines and workloads, like OLTP and DW.
What type of profile would be used?

  • A. Compute
  • B. Database Parameters
  • C. Software Profile Version
  • D. Network

Answer: B

Explanation:
The database parameters profile is used to define the initialization variables for different types of database engines and workloads, such as OLTP and DW. The database parameters profile allows the database administrator to customize the configuration settings for each database engine, such as Oracle, SQL Server, PostgreSQL, and MySQL. The database parameters profile can also be applied to different database operations, such as provisioning, cloning, and patching. The database parameters profile helps to optimize the performance and functionality of the databases according to the specific requirements and best practices of each database engine and workload.
The software profile version is used to define the software version and edition for each database engine, such as Oracle 19c Enterprise Edition or SQL Server 2019 Standard Edition. The software profile version is required for provisioning new databases and patching existing databases. The software profile version helps to ensure the compatibility and compliance of the databases with the supported software versions and editions.
The network profile is used to define the network configuration and security settings for the database server VMs and the databases, such as the IP address, subnet mask, gateway, DNS, firewall rules, and SSL certificates. The network profile is required for registering new database server VMs and provisioning new databases. The network profile helps to ensure the connectivity and protection of the database server VMs and the databases within the network environment.
The compute profile is used to define the compute resources and storage policies for the database server VMs and the databases, such as the CPU, memory, disk size, disk type, compression, deduplication, and replication factor. The compute profile is required for provisioning new databases and cloning existing databases. The compute profile helps to ensure the availability and efficiency of the database server VMs and the databases within the Nutanix cluster.

NEW QUESTION # 49
Which disk is omitted from a Software Profile?

  • A. System Database
  • B. System Page File
  • C. User Database
  • D. SQL Installation

Answer: B

Explanation:
According to the Nutanix Database Automation (NCP-DB) course, a Software Profile is a template that defines the configuration of the database engine, such as the version, edition, features, and parameters1. It also specifies the disk layout for the database installation, such as the size, type, and mount point of each disk1. However, the System Page File disk is omitted from the Software Profile, as it is automatically created by the NDB service based on the memory size of the database server VM1. The other options are included in the Software Profile, as they are essential for the database operation and performance1. References:

NEW QUESTION # 50
When preparing to provision multiple database server VMs, an administrator is tasked with configuring this set of VMs with the same number of cores per vCPU.
What is the easiest way for the administrator to accomplish this task?

  • A. Create a Windows Domain Profile that will synchronize the configurations.
  • B. Update the VMs after provisioning and enter the changes to the vCPU cores.
  • C. After provisioning the VMs. update the DEFAULT_OOB_COMPUTE Profile.
  • D. Create a Compute Profile and apply it to the VMs during provisioning.

Answer: D

Explanation:
A Compute Profile is a template that defines the CPU, memory, and disk resources for a database server VM.
By creating a Compute Profile with the desired number of cores per vCPU, the administrator can easily apply it to multiple VMs during provisioning, ensuring consistent and optimal performance. This also saves time and effort compared to updating the VMs individually or modifying the default profile after provisioning.

NEW QUESTION # 51
Which statement is true regarding the NDB alert retention feature?

  • A. NDB supports retention at the registered cluster.
  • B. NDB supports retention at the grouped policy.
  • C. NDB supports alert retention globally.
  • D. NDB supports retention at the individual policy.

Answer: C

Explanation:
The NDB alert retention feature allows the database administrator to configure the duration for which the NDB alerts are stored and displayed in the NDB instance. The NDB alert retention feature supports alert retention globally, meaning that the same retention period applies to all the alerts generated by the NDB instance, regardless of the source cluster, policy, or operation. The database administrator can set the alert retention period from 1 day to 365 days, or choose to retain the alerts indefinitely. The NDB alert retention feature helps to manage the storage space and the visibility of the NDB alerts.
The NDB alert retention feature does not support retention at the individual policy, grouped policy, or registered cluster level. The NDB alert retention feature applies to all the alerts uniformly, and does not allow the database administrator to specify different retention periods for different policies or clusters.
