Dell Technologies Proven Professional – Information Storage and Management (2023) — Question 13

What is a function of a continuous data protection (CDP) appliance?

Answer options

• A. Migrates deduplicated data from the source volume to the target volume during replication
• B. Intercepts writes to the production volume and splits each write into two copies
• C. Runs data protection software and manages replications within and across data centers
• D. Stores all data that has changed from the time the replication session started

Correct answer: D

Explanation

The correct answer is D because a CDP appliance saves all changes made since the start of the replication session, allowing for point-in-time recovery. Option A describes data migration rather than continuous protection. Option B misrepresents the function by focusing on write interception without mentioning the retention aspect. Option C is more about managing replications than the specific function of capturing data changes.
