Demo Questions

Question 1
Which two statements are true about scheduling operations in a pluggable database (PDB)?
  1. Scheduler jobs for a PDB can be defined only at the container database (CDB) level.
  2. A job defined in a PDB runs only if that PDB is open.
  3. Scheduler attribute setting is performed only at the CDB level.
  4. Scheduler objects created by users can be exported or imported using Data Pump.
  5. Scheduler jobs for a PDB can be created only by common users.
Correct answer: BD
Explanation:
In general, all scheduler objects created by the user can be exported/imported into the PDB using data pump. Predefined scheduler objects will not get exported and that means that any changes made to these objects by the user will have to be made once again after the database has been imported into the pluggable database. However, this is how import/export works currently. A job defined in a PDB will run only if a PDB is open.

Question 2
A complete database backup to media is taken for your database every day. Which three actions would you take to improve backup performance?
  1. Set the backup_tape_io_slaves parameter to true.
  2. Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.
  3. Configure large pool if not already done.
  4. Remove the rate parameter, if specified, in the allocate channel command.
  5. Always use RMAN compression for tape backups rather than the compression provided by media manager.
  6. Always use synchronous I/O for the database.
Correct answer: BCD
Explanation:
Tuning RMAN Backup Performance: Procedure Many factors can affect backup performance. Often, finding the solution to a slow backup is a process of trial and error. To get the best performance for a backup, follow the suggested steps in this section: Step 1: Remove RATE Parameters from Configured and Allocated Channels Step 2: If You Use Synchronous Disk I/O, Set DBWR_IO_SLAVES Step 3: If You Fail to Allocate Shared Memory, Set LARGE_POOL_SIZE Step 4: Tune RMAN Tape Streaming Performance Bottlenecks Step 5: Query V$ Views to Identify Bottlenecks https://docs.oracle.com/database/121/BRADV/rcmtunin.htm#BRADV172

Question 3
For which three pieces of information can you use the RMAN list command?
  1. stored scripts in the recovery catalog
  2. available archived redo log files
  3. backup sets and image copies that are obsolete
  4. backups of tablespaces
  5. backups that are marked obsolete according to the current retention policy
Correct answer: ABD
Explanation:
About the LIST Command: The primary purpose of the LIST command is to list backup and copies. For example, you can list: -Backups and proxy copies of a database, tablespace, datafile, archived redo log, or control file -Backups that have expired -Backups restricted by time, path name, device type, tag, or recoverability -Archived redo log files and disk copies http://docs.oracle.com/cd/B28359_01/backup.111/b28270/rcmreprt.htm#BRADV89585
