Which of the following terms refers to the process of activating alternate systems to restore operations when a disaster strikes?

• A. Failback
• B. Failover
• C. Restoration
• D. Recovery

Answer: (B)

The term that refers to the process of activating alternate systems to restore operations when a disaster strikes is "failover." This process involves automatically or manually switching to a standby database, server, or system to ensure continued operation without significant downtime. Failover is a critical element of business continuity planning and disaster recovery strategies. It allows organizations to maintain availability and minimize disruption when their primary systems are compromised due to a disaster.

In contrast, the term "failback" relates to reverting operations back to the original systems once they are restored and stable. "Restoration" is often used to describe the process of bringing back data and systems after they were compromised or lost, but it does not specifically address the activation of alternative systems during an immediate disaster. "Recovery" encompasses the broader concept of returning to normal operations after any form of interruption or disaster, which could include both the failover and failback processes, but it doesn't specifically denote the act of switching to alternate systems in real time during a crisis. Therefore, "failover" is the most precise term for the activation of alternate systems during a disaster.
