Demo Questions
Question 1
Which two statements are true about scheduling operations in a pluggable database (PDB)?
- Scheduler jobs for a PDB can be defined only at the container database (CDB) level.
- A job defined in a PDB runs only if that PDB is open.
- Scheduler attribute setting is performed only at the CDB level.
- Scheduler objects created by users can be exported or imported using Data Pump.
- 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?
- Set the backup_tape_io_slaves parameter to true.
- Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.
- Configure large pool if not already done.
- Remove the rate parameter, if specified, in the allocate channel command.
- Always use RMAN compression for tape backups rather than the compression provided by media manager.
- 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 Reference:https://docs.oracle.com/database/121/BRADV/rcmtunin.htm#BRADV172 Tuning RMAN Backup Performance: Procedure Many factors can affect backup performance.

Question 3
Because of logical corruption of data in a table, you want to recover the table from an RMAN backup to a specified point in time.
Examine the steps to recover this table from an RMAN backup:
- Determine which backup contains the table that needs to be recovered.
- Issue the recover table RMAN command with an auxiliary destination defined and the point in time specified.
- Import the Data Pump export dump file into the auxiliary instance.
- Create a Data Pump export dump file that contains the recovered table on a target database.
Identify the required steps in the correct order.
- 1, 4, 3
- 1, 2
- 1, 4, 3, 2
- 1, 2, 4
Correct answer: D
Explanation:
Because according to oracle PDFs if you run restore table ... auxiliary a impede and rename can be included. So there is no reason to make the import manually if it can be already included in step 2.
