NEW QUESTION 100
Your multitenant container database (CDB) contains multiple pluggable databases (PDBs). You execute the command to create a common user:
SQL> CREATE USER c##a_admin
IDENTIFIED BY password
DEFAULT TABLESPACE users
QUOTA I00M ON users
TEMPORARY TABLESPACE temp;
Which statement is true about the execution of the command?
- A. The command succeeds only if all the PDBs have the users and temp tablespaces.
- B. The command gives an error because the container=all clause is missing.
- C. The command succeeds and sets the default permanent tablespace of a PDB as the default tablespace for the c##a_admin user if the users tablespace does not exist in that PDB.
- D. The common user is created in the CDB and all the PDBs, and uses the users and temp tablespaces of the CDB to store schema objects.
Answer: A
Explanation:
Explanation
When creating a common user, any tablespace, tablespace group or profile specified in the CREATE command must exist in every PDB. If none of these are specified, the default TABLESPACE, TEMPORARY TABLESPACE, and PROFILE for the PDB will be used.
NEW QUESTION 101

NAME TYPE VALUE
----------------------------------------------------------------------------------------------------- optimizer_adaptive_reporting_onlyboolean FALSE optimizer_capture_sql_plan_baselinesboolean FALSE optimizer_dynamic_samplinginteger 2 optimizer_features_enablestring 12.1.0.1 Which three statements are true about the process of automatic optimization by using statistics feedback?
- A. The optimizer automatically changes a plan during subsequent execution of a SQL statement if there is a huge difference in optimizer estimates and execution statistics.
- B. The optimizer enables monitoring for cardinality feedback after the first execution of a query.
- C. The optimizer does not monitor cardinality feedback if dynamic sampling and multicolumn statistics are enabled.
- D. The optimizer can re optimize a query only once using cardinality feedback.
- E. After the optimizer identifies a query as a re-optimization candidate, statistics collected by the collectors are submitted to the optimizer.
Answer: A,B,C
Explanation:
Explanation/Reference:
Explanation:
C: During the first execution of a SQL statement, an execution plan is generated as usual.
D: if multi-column statistics are not present for the relevant combination of columns, the optimizer can fall back on cardinality feedback.
(not B)* Cardinality feedback. This feature, enabled by default in 11.2, is intended to improve plans for repeated executions.
optimizer_dynamic_sampling
optimizer_features_enable
Dynamic sampling or multi-column statistics allow the optimizer to more accurately estimate selectivity of conjunctive predicates.
Note:
* OPTIMIZER_DYNAMIC_SAMPLING controls the level of dynamic sampling performed by the optimizer.
Range of values. 0 to 10
Cardinality feedback was introduced in Oracle Database 11gR2. The purpose of this feature is to automatically improve plans for queries that are executed repeatedly, for which the optimizer does not estimate cardinalities in the plan properly. The optimizer may misestimate cardinalities for a variety of reasons, such as missing or inaccurate statistics, or complex predicates. Whatever the reason for the misestimate, cardinality feedback may be able to help.
NEW QUESTION 103
Which Oracle Database component is audited by default if the Unified Auditing option is enabled?
- A. Oracle Recovery Manager (RMAN)
- B. Oracle Label Security
- C. Oracle Database Vault
- D. Oracle Data Pump
- E. Oracle Real Application Security
Answer: A
Explanation:
Unlike other Oracle Database components, you do not create a unified audit policy for Oracle Recovery Manager events. The UNIFIED_AUDIT_TRAIL data dictionary view has a set of fields, whose names begin with RMAN_, that automatically record Recovery Manager-related events.

Examine the command executed to back up pdb2_1:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which statement is true about the execution of this command?
- A. It succeeds but only the data files belonging to the pdb2_i pluggable database are backed up.
- B. It fails because archive log files cannot be backed up using a connection to a PDB.
- C. It succeeds and all data files belonging to PD2_i are backed up along with the archive log files.
- D. It fails because the pluggable clause is missing.

Which three statements are true about persistent lightweight jobs?
- A. The are useful when users need to create a large number of jobs quickly.
- B. They may be created as fully self-contained jobs.
- C. They generate large amounts of metadata.
- D. They must reference an existing Scheduler Program.
- E. A user cannot set privileges on them.
Answer: A,D,E
Explanation:
Explanation/Reference:
Explanation:
Unlike regular jobs, they are not schema objects. Because lightweight jobs are not schema objects, you cannot grant privileges on them. A lightweight job inherits privileges from its specified program. Thus, any user who has a certain set of privileges on the program has corresponding privileges on the lightweight job. Use lightweight jobs when you have many short-duration jobs that run frequently. Under certain circumstances, using lightweight jobs can deliver a small performance gain. A lightweight job must reference a program object (program) to specify a job action. The program must be already enabled when the lightweight job is created, and the program type must be either 'PLSQL_BLOCK' or
'STORED_PROCEDURE'.
