Dell EMC Associate – Information Storage and Management v5 — Question 1

Which data deduplication method would a cloud service provider use when storing back up data at their location?

Answer options

• A. Source-based
• B. Target-based
• C. Application-based
• D. Agent-based

Correct answer: A

Explanation

The correct answer is A, Source-based deduplication, as it reduces data at the source before it is sent to the cloud, saving bandwidth and storage space. The other methods, such as Target-based, Application-based, and Agent-based deduplication, either process data after it has been transferred or use agents which may not be efficient for a cloud service provider's backup data management.
