Which are three of the steps taken by Database Configuration Assistant (DBCA) to clone a remote pluggable database (PDB) starting from Oracle 19c?

  1. creating a database link from CDB$ROOT in the local database to CDB$ROOT in the remote system that is to be cloned
  2. creating a database link from CDB$ROOT in the local database to the PDB in the remote system that is to be cloned
  3. backing up the cloned PDB
  4. opening the cloned PDB
  5. leaving the cloned PDB in mount state

Answer(s): A,D



Which three are true about thresholds, metrics, and server-generated alerts? (Choose three.)

  1. All metrics are instance related.
  2. Cleared stateful alerts are displayed by querying DBA_ALERT_HISTORY.
  3. A space usage management alert is automatically cleared after the underlying problem is resolved
  4. They are generated by SMON when a tablespace is 97% full.
  5. Metrics are statistical counts for a specific unit.
  6. STATISTICS_LEVEL must be set to ALL to generate alerts.

Answer(s): B,C,E



Choose three. In which three situations can you use threshold server-generated alerts to help diagnose and fix problems?

  1. when free space in a dictionary managed tablespace falls below a specified percentage
  2. when free space in a locally managed tablespace falls below a specified percentage
  3. when the total number of locked user account exceeds a specific value
  4. when the number of logons per second exceeds a specific value
  5. when a resumable statement is suspended
  6. when the total number of logons exceeds a specific value

Answer(s): B,C,D



While backing up to an SBT channel, you determine that the read phase of your compressed Recovery Manager (RMAN) incremental level 0 backup is a bottleneck. FORCE LOGGING is enabled for the database. Which two could improve read performance? (Choose two.)

  1. Increase the size of tape I/O buffers.
  2. Disable FORCE LOGGING for the database.
  3. Increase the size of the database buffer cache.
  4. Enable asynchronous disk I/O.
  5. Increase the level of RMAN multiplexing.

Answer(s): B,C



For which two requirements can you use the USER_TABLESPACE clause with the CREATE PLUGGABLE DATABASE command? (Choose two.)

  1. to specify a default tablespace in a PDB cloned from another PDB in the same CDB
  2. to exclude all tablespaces except SYSTEM, SYSAUX, and TEMP when plugging in a PDB
  3. to include specific user tablespaces only when relocating a PDB
  4. to specify the list of user tablespaces to include when moving a non-CDB to a PDB
  5. to exclude a temp tablespace when plugging in a PDB
  6. to specify the list of tablespaces to include when creating a PDB from the CDB seed

Answer(s): B,D
