20+ practice questions focused on Backup And Recovery — one of the most tested topics on the Oracle Database 23ai Administrator Professional (OCP, 1Z0-183) (OCP) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Backup And Recovery PracticeYou need to perform a table-level point-in-time recovery. Which RMAN command syntax is correct?
Explanation: The correct RMAN command for table-level point-in-time recovery is RECOVER TABLE HR.EMPLOYEES UNTIL SCN 12345;. This command restores the specified table to a particular SCN by creating a temporary auxiliary instance, recovering the table, and then importing it back into the original database. It is designed for table-level recovery without affecting other tablespaces.
Which TWO RMAN settings significantly improve performance during backup operations on an Exadata system?
Explanation: Option C, CONFIGURE BACKUP OPTIMIZATION ON, is correct because it enables RMAN to skip backing up datafiles or archived redo logs that are identical to previously backed-up versions, drastically reducing I/O and elapsed time on Exadata systems where large volumes of unchanged data exist. Option D, CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET, is correct because compressing backupsets reduces the amount of data written to disk and the associated I/O, which significantly improves backup performance on Exadata's high-throughput storage. Option A is incorrect because RATE 10M artificially throttles the channel to 10 MB/s, which would slow backups rather than improve performance. Option B is incorrect because MAXSETSIZE UNLIMITED does not enhance performance; it only removes the size limit per backupset and can even reduce parallelism. Option E is incorrect because disabling the controlfile autobackup removes a safety net and has no positive performance impact on backup operations.
You are migrating an Oracle 23ai database to a different platform with different endianness. Which RMAN command is used to convert the datafiles to the target platform format?
Explanation: The CONVERT DATAFILE command is required when the source and destination platforms have different endian formats.
You are performing a cross-platform transportable tablespace migration from Linux to Windows. Which RMAN command is required to convert the datafiles for the destination platform?
Explanation: The CONVERT TABLESPACE command is used to change the endian format for cross-platform migrations.
Your database is in ARCHIVELOG mode. You accidentally dropped a critical tablespace and need to perform a Tablespace Point-in-Time Recovery (TSPITR). What is the primary requirement for the auxiliary instance during this process?
Explanation: The primary requirement for the auxiliary instance during TSPITR is that it must have enough disk space to hold the tablespace being recovered, along with the SYSTEM, SYSAUX, and UNDO tablespaces needed to open the auxiliary database. RMAN automatically creates and manages the auxiliary instance, so manual startup or separate ORACLE_HOME is not required.

Start with 10 questions to gauge your current understanding of Backup And Recovery. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Backup And Recovery questions on the OCP frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
