Statement: A disaster recovery system is unnecessary for preventing service interruptions. Is this statement True or False?

• A. Not Applicable
• B. Cannot Be Determined
• C. True
• D. False

Answer: (D)

Disaster recovery is about restoring IT services quickly after a disruption to minimize how long those services are down. Saying it’s unnecessary to prevent interruptions is not correct, because the value of a DR system is to reduce the duration of an outage by having backups, replication to a secondary site, automated failover, and tested recovery procedures in place. It doesn't stop the disaster from occurring, but it enables fast restoration to meet objectives like Recovery Time Objective (RTO) and Recovery Point Objective (RPO). For example, if a data center goes offline due to a disaster, a DR plan can switch operations to a remote site with minimal downtime, keeping services available. So, the statement is false—the DR system is essential for preventing service interruptions from lasting too long.
