NEW QUESTION # 27
Refer to the exhibit:
Refer to the exhibit, which two actions does this Python code perform with the Cisco ACI? (Choose two.) It creates a subnet "DevNet_Subnet" inside VRF "DevNet_VRF" located in ACI tenant "DevNet_Tenant" and sets the scope to "private"
- A. It creates a subnet "DevNet_Subnet" inside AppProfile "DevNet_App" located in ACI tenant
"DevNet_Tenant" and sets the network address to "10.10.10 1/24" - B. It creates an EPG "DevNet_EPG" inside AppProfile "DevNet_App" located in ACI tenant
"DevNet_Tenant" and link the EPG with BridgeDomain "DevNet_BD" - C. It creates a subnet "DevNet_Subnet" inside VRF "DevNet_VRF" located in ACI tenant
"DevNet_Tenant" and sets the network address to "10.10 10.1/24". - D. It creates an EPG "DevNet_EPG" inside VRF "DevNet_VRF" located in ACI tenant "DevNet_Tenant" and link the EPG with BridgeDomain "DevNet BD"
Answer: B,C
Explanation:
The Python code in the exhibit is using the Cobra SDK to interact with Cisco's Application Centric Infrastructure (ACI). The code performs the following actions:
* It logs into the ACI fabric using credentials provided.
* It creates a new Virtual Routing and Forwarding (VRF) instance named "DevNet_VRF" within a tenant named "DevNet_Tenant".
* It creates a new Bridge Domain (BD) named "DevNet_BD" within the same tenant and associates it with the previously created VRF.
* It defines a subnet within this Bridge Domain with the network address "10.10.10.1/24", which is labeled as "DevNet_Subnet".
* An Application Profile (AppProfile) named "DevNet_App" is created within the tenant.
* An Endpoint Group (EPG) named "DevNet_EPG" is created and associated with both the AppProfile ("DevNet_App") and BridgeDomain ("DevNet_BD").
Therefore, options B and C are correct: B. This action creates an EPG called "DevNet_EPG" inside an AppProfile called "DevNet_App" located in an ACI tenant called "DevNet_Tenant". The EPG is linked to a BridgeDomain called "DevNet_BD". C. This action creates a subnet called "DevNet_Subnet" inside VRF
"DevNet_VRF" located in an ACI tenant called "DevNet_Tenant" and sets its network address to
"10.10.10.1/24".

Using the NX-API CLI JSON-RPC interface, which two Python data structure and requests call create an SVI?
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer: A,C
Explanation:
To create an SVI using NX-API CLI JSON-RPC interface, one would typically need to construct a Python dictionary that represents the RPC payload containing the necessary commands. The request call would then be made using a library like requests where this dictionary is passed as JSON data. In general terms, without specifying exact options since they are not visible in any provided resources or within my capabilities:
* One option would likely involve specifying parameters for creating an SVI including its ID number.
* Another option might involve setting specific attributes for the SVI such as name, description, or IP address. References :=

NEW QUESTION # 33
What is a characteristic of synchronous and asynchronous API calls?
- A. Synchronous API calls must always use a proxy server.
- B. Synchronous communication is harder to follow and troubleshoot
- C. ASynchronous communication uses more overhead for client authentication
- D. Synchronous API calls wait to return until a response has been received
Answer: D
Explanation:
* This means the client initiating the API call will wait for the server to process the request and return a response before moving on to other tasks, which can be simpler to implement and debug but may be less efficient if the server takes a long time to respond.
References:
* General programming and API design principles

NEW QUESTION # 37
How should the Kubernetes manifests be modified to allow Kubernetes environment integration with Cisco ACI?
- A. The manifests must include ACI EPG reference
- B. The manifest does not have to be changed, but the Kubemetes object is not discovered by Cisco ACI if this is not defined in the manifest
- C. The metadata section must contain the Cisco APIC management IP
- D. No change is needed to perform this action.
Answer: A
Explanation:
In order to integrate a Kubernetes environment with Cisco ACI, the Kubernetes manifests typically need to include references to ACI End Point Groups (EPGs). This allows for the application components within Kubernetes to be associated with the networking policies defined in ACI, ensuring consistent network policy application across both environments. References: Since I can't provide direct links to external sources, I recommend checking Cisco's official documentation and training materials for the most accurate and up-to-date information.

What mode is required on a Cisco Nexus 7000 32-port 10-GB module port group to allow equal access to the
10-GB port controller?
- A. assigned
- B. dedicated
- C. shared
- D. community
Answer: C
Explanation:
You can share 10 Gb of bandwidth among a group of ports (four ports) on a 32-port 10-Gigabit Ethernet module. To share the bandwidth, you must bring the dedicated port administratively down, specify the ports that are to share the bandwidth, change the rate mode to shared, and then bring the ports administratively up.

Which protocol is the foundation for unified fabric as implemented in Cisco NX-OS?
- A. Data Center Bridging
- B. N proxy virtualization
- C. N Port identifier virtualization
- D. Fibre Channel
- E. Fibre Channel over Ethernet
Answer: E
Explanation:
Fibre Channel over Ethernet (FCoE) is one of the major components of a Unified Fabric. FCoE is a new technology developed by Cisco that is standardized in the Fibre Channel Backbone 5 (FC-BB- 5) working group of Technical Committee T11 of the International Committee for Information Technology Standards (INCITS). Most large data centers have huge installed bases of Fibre Channel and want a technology that maintains the Fibre Channel model. FCoE assumes a lossless Ethernet, in which frames are never dropped (as in Fibre Channel) and that therefore does not use IP and TCP.
