Demo Questions

Question 1
Which two statements are true concerning the Resource Manager plans for individual pluggable databases (PDB plans) in a multitenant container database (CDB)? (Choose two.)

  • A: If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that PDB.
  • B: In a PDB plan, subplans may be used with up to eight consumer groups.
  • C: If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the CDB.
  • D: If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
  • E: If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.



Question 2
You use a recovery catalog for maintaining your database backups. 
You execute the following command:
$rman TARGET / CATALOG rman / [email protected] 
RMAN > BACKUP VALIDATE DATABASE ARCHIVELOG ALL; 
Which two statements are true? (Choose two.)

  • A: Corrupted blocks, if any, are repaired.
  • B: Checks are performed for physical corruptions.
  • C: Checks are performed for logical corruptions.
  • D: Checks are performed to confirm whether all database files exist in correct locations
  • E: Backup sets containing both data files and archive logs are created.



Question 3
Which three statements are true concerning the multitenant architecture? (Choose three.)

  • A: Each pluggable database (PDB) has its own set of background processes.
  • B: A PDB can have a private temp tablespace.
  • C: PDBs can share the sysaux tablespace.
  • D: Log switches occur only at the multitenant container database (CDB) level.
  • E: Different PDBs can have different default block sizes.
  • F: PDBs share a common system tablespace.
  • G: Instance recovery is always performed at the CDB level.



Question 4
You notice that the elapsed time for an important database scheduler Job is unacceptably long. 
The job belongs to a scheduler job class and window. 
Which two actions would reduce the job's elapsed time? (Choose two.)

  • A: Increasing the priority of the job class to which the job belongs
  • B: Increasing the job's relative priority within the Job class to which it belongs
  • C: Increasing the resource allocation for the consumer group mapped to the scheduler job's job class within the plan mapped to the scheduler window
  • D: Moving the job to an existing higher priority scheduler window with the same schedule and duration
  • E: Increasing the value of the JOB_QUEUE_PROCESSES parameter
  • F: Increasing the priority of the scheduler window to which the job belongs



Question 5
You plan to migrate your database from a File system to Automata Storage Management (ASM) on same platform. 
Which two methods or commands would you use to accomplish this task? (Choose two.)

  • A: RMAN CONVERT command
  • B: Data Pump Export and import
  • C: Conventional Export and Import
  • D: The BACKUP AS COPY DATABASE . . . command of RMAN
  • E: DBMS_FILE_TRANSFER with transportable tablespace



Question 6
You run a script that completes successfully using SQL*Plus that performs these actions:
Creates a multitenant container database (CDB) 
Plugs in three pluggable databases (PDBs) 
Shuts down the CDB instance 
Starts up the CDB instance using STARTUP OPEN READ WRITE 
Which two statements are true about the outcome after running the script? (Choose two.)

  • A: The seed will be in mount state.
  • B: The seed will be opened read-only.
  • C: The seed will be opened read/write.
  • D: The other PDBs will be in mount state.
  • E: The other PDBs will be opened read-only.
  • F: The PDBs will be opened read/write.



Question 7
You execute the following piece of code with appropriate privileges:

  

User SCOTT has been granted the CREATE SESSION privilege and the MGR role. 
Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table? (Choose two.)

  • A: Data is redacted for the EMP.SAL column only if the SCOTT session does not have the MGR role set.
  • B: Data is redacted for EMP.SAL column only if the SCOTT session has the MGR role set.
  • C: Data is never redacted for the EMP_V.SAL column.
  • D: Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.
  • E: Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set.



Question 8
Your database is open and the LISTENER listener running. You stopped the wrong listener LISTENER by issuing the following command:
1snrctl > STOP 
What happens to the sessions that are presently connected to the database Instance?

  • A: They are able to perform only queries.
  • B: They are not affected and continue to function normally.
  • C: They are terminated and the active transactions are rolled back.
  • D: They are not allowed to perform any operations until the listener LISTENER is started.



Question 9
Which three statements are true about using flashback database in a multitenant container database (CDB)? (Choose three.) (Choose three.)

  • A: The root container can be flashed back without flashing back the pluggable databases (PDBs).
  • B: To enable flashback database, the CDB must be mounted.
  • C: Individual PDBs can be flashed back without flashing back the entire CDB.
  • D: The DB_FLASHBACK RETENTION_TARGET parameter must be set to enable flashback of the CDB.
  • E: A CDB can be flashed back specifying the desired target point in time or an SCN, but not a restore point.



Question 10
You execute the following PL/SQL:

  

Which two statements are true? (Choose two.)

  • A: Fine-Grained Auditing (FGA) is enabled for the PRICE column in the PRODUCTS table for SELECT statements only when a row with PRICE > 10000 is accessed.
