Dell EMC Specialist – Systems Administrator, Unity XT — Question 2

A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity feature could reduce failover times?

Answer options

• A. QoS Failover Policy
• B. Cabinet Failover
• C. SRDF Metro
• D. Consistency Groups

Correct answer: D

Explanation

Consistency Groups allow for the coordination of data replication across multiple NAS servers, ensuring that all changes are applied consistently before a failover occurs. This reduces the time it takes to switch to a backup system during a failure. The other options do not specifically address the timing of failovers in the same manner as Consistency Groups.
