Oracle Database 11g: Administration I — Question 15

Which two are true about the Archive (ARCn) processes? (Choose two.)

Answer options

• A. They are enabled only when the database is in ARCHIVELOG mode
• B. They create archivelogs after every log switch
• C. They are used during instance recovery
• D. They automatically delete obsolete archive logs to make space for new archive logs
• E. They archive redo directly from the redo log buffer

Correct answer: A, D

Explanation

Option A is correct because ARCn processes are only functional when the database is set to ARCHIVELOG mode. Option D is also correct as ARCn processes manage the deletion of obsolete archive logs to free up space. Options B, C, and E are incorrect as they do not accurately describe the primary functions of the ARCn processes.
