Designing Cisco Data Center Infrastructure (DCID) — Question 151

A customer is evaluating a new disaster-recovery solution for their SAN, which is used for noncritical CRM purposes. The SAN is frequently backed up locally at the customer's existing single location, and several hours of data loss can be sustained. The customer wants to retain complete control of the failover process to a separate physical location. Which type of DR is most suitable for the customer?

Answer options

• A. active/passive
• B. cold standby
• C. active/active
• D. warm standby

Correct answer: D

Explanation

The warm standby option is correct because it allows for a backup system that is partially running and can be quickly activated in case of a failure, giving the customer control over the failover process. Active/passive and cold standby do not provide the desired level of control or immediacy, while active/active setups are typically more complex and unnecessary for the client's needs.
