CERTIFIED-IN-CYBERSECURITY Question #511: Real Exam Question with Answer & Explanation

Question

Until the generators start up and stabilize, what do battery backups need to be properly sized to carry?

Options

• AThe critical load
• BThe network load
• CThe HVAC load
• DThe fire suppression load

Explanation

Battery backups need to be adequately sized to carry the critical load until the generators start up and stabilize. The critical load refers to the power required to keep essential systems running, such as servers, storage devices, and network equipment (see ISC2 Study Guide, Chapter 4, Module 3). For instance, in a data center, if there is a power outage, the battery backups (also known as Uninterruptible Power Supply or UPS) should be able to provide sufficient power to keep the critical systems operational until the generators are up and running. While important, other options are not the primary considerations when sizing battery backups. The HVAC load is part of the supporting infrastructure, but it is not typically considered a critical load that must be maintained during a power outage. The network load (option B) is part of the critical load but is not the only component of the critical load. The fire suppression load is also important, but it typically requires power to a different extent than the critical load. Therefore, while all these systems are important in a data center, the battery backups must be primarily sized to support the critical load until the generators start up and stabilize.
