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.
