Certified Information Systems Auditor (CISA) — Question 73

An organization is running servers with critical business applications that are in an area subject to frequent but brief power outages. Knowledge of which of the following would allow the organization's management to monitor the ongoing adequacy of the uninterruptible power supply (UPS)?

Answer options

Correct answer: A

Explanation

Knowing the duration and interval of the power outages (Option A) is crucial for evaluating if the UPS can handle the frequency and length of outages effectively. The business impact of server downtime (Option B) is important but does not directly measure UPS adequacy. The number of servers supported by the UPS (Option C) is relevant but does not provide insights into ongoing performance. Mean time to recover servers after failure (Option D) is more about recovery than monitoring UPS adequacy.
