Certified Information Systems Auditor (CISA) — Question 664

Which of the following is a characteristic of a single mirrored data center used for disaster recovery?

Answer options

• A. Data replication to the mirrored site should continue after failover.
• B. The mirrored site may create brief interruptions noticeable to users.
• C. Real-time data replication occurs from the production site.
• D. The mirrored data center does not require staffing.

Correct answer: C

Explanation

The correct answer is C because a single mirrored data center should have real-time data replication from the production site to ensure minimal data loss during a disaster. Option A is incorrect as replication should not need to continue post-failover; B is wrong because the goal is to minimize interruptions; D is false since staffing is often required for operations and monitoring.
