Dell EMC SC Series Storage Professional — Question 5

An administrator needs to replicate data to an off-site Storage Center. Data on both sides must always match. The administrator must have the data sent to the remote system as soon as the data is written. If the communication to the remote system fails, all writes to the local system must stop.
Which option should the administrator choose to meet the requirements?

Answer options

• A. synchronous replication with High Consistency
• B. synchronous replication with High Availability
• C. asynchronous replication of the Active Replay
• D. asynchronous replication with frequent replays

Correct answer: C

Explanation

The correct answer is C because asynchronous replication of the Active Replay allows data to be sent to the remote site without halting local operations, which is necessary when communication fails. Options A and B involve synchronous replication, which would require halting local writes if the connection fails, contradicting the requirement. Option D also implies asynchronous replication but does not ensure immediate data matching as required.
