Dell Technologies Proven Professional – Midrange Storage Solutions — Question 48

Which describes cascade replication on the Dell Unity XT platform?

Answer options

• A. Asynchronous replication of a file resource from Sites A to B, then В to C, then С to D
• B. Asynchronous replication of a block resource from Sites A to B, then В to C, then С to D
• C. Synchronous replication of a block resource from Sites A to B, then В to C, then С to D
• D. Synchronous replication of a file resource from Sites A to B, then В to C, then С to D

Correct answer: A

Explanation

The correct answer is A because cascade replication specifically involves asynchronous replication of file resources across multiple sites. The other options incorrectly describe the type of replication (synchronous vs asynchronous) or the resource type (file vs block), making them incorrect for this scenario.
