CERTIFIED-IN-CYBERSECURITY Question #475: Real Exam Question with Answer & Explanation

Question

In a data center, what do backup generators need to be sized for?

Options

• AThe network and supporting infrastructure
• BThe fire suppression system and supporting infrastructure
• CThe critical load and supporting infrastructure
• DThe HVAC system and supporting infrastructure

Explanation

Backup generators in a data center must be sized for the critical load and supporting infrastructure because the primary function of backup generators is to provide power to critical systems and infrastructure in the event of a power outage (see ISC2 Study Guide, Chapter 4, Module 3). For example, suppose a data center hosts a critical application that must be available 24/7. In this case, the backup generators must be sized to support the servers running that application and the supporting infrastructure, such as cooling systems, power distribution units, and lighting. The other options, while important, are not the primary considerations when sizing backup generators. The HVAC system and supporting infrastructure are part of the supporting infrastructure that the backup generators must support, but they are not the critical load. The fire suppression system and supporting infrastructure are also important, but typically require less power than the critical load and supporting infrastructure. The network and supporting infrastructure are also part of the supporting infrastructure, but again, they are not the critical load that the backup generators must be sized to support.
