Archived Redo Log is
AnswerClick to flip back
A
It consists of Redo Log files that have archived before being reused.
💡 Explanation:
Archived Redo Logs are copies of online redo log files that have been saved before being reused. When an online redo log fills, Oracle switches to a new log. Archiving (if enabled) copies the filled log to an archive location before it can be overwritten. Option A correctly states they are archived before reuse. Option B is incorrect because archiving happens before, not after, reuse. Option C incorrectly suggests archiving occurs during reuse. Option D is incorrectly phrased and unclear.
