Oracle Database Administration II — Question 94

Which two are true about RMAN Multisection backups when a very large data file is divided into four sections? (Choose two.)

Answer options

• A. Each of the file sections must be processed serially.
• B. The four sections can be created serially.
• C. The four sections must be image copies.
• D. The four sections can be created in parallel.
• E. The four sections must be contained in backup sets.

Correct answer: B, D

Explanation

The correct answers are B and D because RMAN allows the sections to be created serially and in parallel, maximizing efficiency. Options A and C are incorrect as RMAN does not require serial processing for all sections, and the sections do not need to be image copies; they can also be backup sets.
