IT Operations Management (ITOM) Practice Exam 2026 - Free ITOM Practice Questions and Study Guide

Capacity management ensures IT resources are available to meet current and future business demand in a cost-effective way while keeping service levels intact. It involves understanding how demand will grow or change, measuring how capacity is being used, forecasting needs, and planning how to scale compute, storage, networks, and related services. The aim is to balance performance with cost, avoiding both over-provisioning and under-provisioning so that services remain reliable and affordable as requirements evolve.

Maximizing utilization without regard to actual demand can waste resources or cause failures when demand spikes, and focusing only on server capacity misses other critical components like networks and applications that impact performance. Narrowly removing assets to cut costs can degrade service levels by reducing available capacity.
