To validate the high-availability claim for a major sporting venue, which testing type is essential?

• A. Vulnerability testing
• B. Penetration testing
• C. Load testing
• D. Failover testing

Answer: (D)

Testing failover and redundancy is essential to validate high availability. For a major sporting venue, the goal is that critical services stay online even if a component or site fails. Failover testing verifies that the system automatically switches to a backup without noticeable downtime, checks that failover triggers work correctly, and confirms that data remains consistent and services recover within the required recovery objectives. It also validates the coordination between primary and standby resources, the timing of the switch, and the monitoring that signals a failure. Security-focused tests like vulnerability and penetration testing examine weaknesses that could be exploited, but they don’t prove that automatic failover will function when a failure occurs. Load testing assesses performance under heavy load, which is important but doesn’t by itself demonstrate the ability to maintain service continuity through failures.
