ITPEC FE Morning April 2022 Question 57
In the capacity management process of IT service management, which of the following is an appropriate precaution to observe when the utilization of an online system’s capacity is monitored?
Explanation
Monitor several items, such as response time and CPU utilization, regularly — capacity problems show up in different metrics and build up over time.
Capacity management makes sure resources meet the agreed performance now and in the future. A bottleneck can appear in the CPU, memory, disk I/O or network, and users feel it as longer response time, so one metric can look fine while another degrades. Regular measurement also builds the trend data needed to forecast when capacity will run out and to plan upgrades before the service level suffers.
Answer (c)
Why not others:
- •(a) — watching only the peak in each interval hides averages and trends: a single spike may be an outlier, and a steady rise below the limit goes unnoticed
- •(b) — measurements taken in offline hours do not reflect the online load the capacity must serve
- •(d) — recording incidents is not a precaution for monitoring; it logs problems after users are affected, while monitoring is meant to catch the trend before that
Key rule: Capacity monitoring is proactive: measure several resources and the user-facing response time under the real load, and watch the trend, not just the peaks.
