Question 71

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

  1. 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.
  2. In a PDB plan, subplans may be used with up to eight consumer groups.
  3. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the CDB.
  4. If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
  5. 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

Question 72

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

  1. Corrupted blocks, if any, are repaired.
  2. Checks are performed for physical corruptions.
  3. Checks are performed for logical corruptions.
  4. Checks are performed to confirm whether all database files exist in correct locations
  5. Backup sets containing both data files and archive logs are created.

Question 73

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

  1. Each pluggable database (PDB) has its own set of background processes.
  2. A PDB can have a private temp tablespace.
  3. PDBs can share the sysaux tablespace.
  4. Log switches occur only at the multitenant container database (CDB) level.
  5. Different PDBs can have different default block sizes.
  6. PDBs share a common system tablespace.
  7. Instance recovery is always performed at the CDB level.

Question 74

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.)

  1. Increasing the priority of the job class to which the job belongs
  2. Increasing the job's relative priority within the Job class to which it belongs
  3. Increasing the resource allocation for the consumer group mapped to the scheduler job's job class within the plan mapped to the scheduler window
  4. Moving the job to an existing higher priority scheduler window with the same schedule and duration
  5. Increasing the value of the JOB_QUEUE_PROCESSES parameter
  6. Increasing the priority of the scheduler window to which the job belongs

Question 75

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.)

  1. RMAN CONVERT command
  2. Data Pump Export and import
  3. Conventional Export and Import
  4. The BACKUP AS COPY DATABASE . . . command of RMAN
  5. DBMS_FILE_TRANSFER with transportable tablespace
