ITPEC FE Subject A April 2026 Question 13
The operating status of a system is being continuously monitored. When a new task is applied to the system after several years of operation, which of the following is an appropriate sequence of work items in capacity planning?
[Work items in capacity planning]
(i)Evaluate the proposed system configuration, assess its appropriateness, and conduct a review if necessary.(ii)Consider a proposal for the necessary system configuration based on system characteristics, including factors such as the number of servers and whether parallel distributed processing can be performed.(iii)Understand the performance information of the hardware or environment inherent to the system based on the operating status of the system.(iv)Conduct a meeting with users to gather information about the new task, understand requirements such as the estimated number of processes, and determine the time required by the processes.Explanation
(iii), (iv), (ii), (i) — measure the current system, learn the new demand, propose a configuration, then review it.
Capacity planning for a new task on a running system goes:
- (iii) Establish the baseline: the hardware and environment performance, from the monitoring data already collected
- (iv) Gather the new task's requirements from users: estimated number of processes and the time they need
- (ii) Propose a configuration that meets them: number of servers, whether processing can be distributed in parallel
- (i) Evaluate the proposal for appropriateness and review it if necessary
Answer (b)
Why not others:
- •(a) (iii), (ii), (iv), (i) — proposes a configuration before learning what the new task requires
- •(c) (iv), (ii), (i), (iii) — designs and approves the configuration before looking at the current system's performance
- •(d) (iv), (iii), (i), (ii) — evaluates the proposal at step 3, before it is made at step 4
Key rule: Capacity planning gathers its inputs (current performance and new demand) first, then designs, then reviews the design.
