Oracle Database Administration II — Question 62

Which two are true about RMAN backups when using a media manager to write backups to tape when there are only two tape drives? (Choose two.)

Answer options

• A. SBT tape compression can be used even if no RMAN compression is configured.
• B. Any backup set written to the SBT device in this configuration can contain a maximum of two backup pieces.
• C. Any backup written to the SBT device in this configuration can contain a maximum of two backup sets.
• D. SBT tape compression and RMAN backup compression should be used in parallel.
• E. The SBT device should be configured to use PARALLELISM 2 to allow both tape drive to be used simultaneously.

Correct answer: A, E

Explanation

Option A is correct because SBT tape compression operates independently of RMAN's compression settings. Option E is also correct as it allows both tape drives to be utilized simultaneously for more efficient backups. Options B and C are incorrect since they misinterpret the relationship between backup pieces and sets in the context of SBT. Option D is incorrect because using both compression methods simultaneously may not be necessary or beneficial.
