Dell EMC Specialist – Systems Administrator, Unity XT — Question 88

Which describes cascade replication on a Dell Unity XT?

Answer options

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

Correct answer: C

Explanation

The correct answer is C, as cascade replication involves synchronous replication which ensures that the block resource is replicated in real-time across the specified sites. Options A and D describe file resources, while option B refers to asynchronous replication, which does not align with the definition of cascade replication.
