Which type of IT resource is most likely to become a bottleneck during a rapid increase in business demand?
Computing infrastructure absorbs the direct processing load of increased transactions, so rapid demand growth saturates CPU, memory and throughput first. Storage and network capacity can often be expanded with less immediate effect on service delivery, making compute the most likely bottleneck during a sudden surge.
Why this answer
Computing infrastructure (servers, storage, network capacity) is a finite, physical resource that cannot scale instantly, so a rapid spike in business demand will exhaust capacity and create a bottleneck. Policies, culture, and documentation are intangible and do not constrain throughput in the same way. This makes computing infrastructure the most likely bottleneck under sudden demand growth.
Exam trap
CGEIT often tests the misconception that governance artifacts (policies, culture, documentation) are the primary constraints on IT performance, when the exam expects recognition that physical infrastructure capacity is the binding constraint under demand spikes.
How to eliminate wrong answers
Option A is wrong because policies and procedures are governance artifacts that shape behavior but do not directly constrain transaction throughput or processing capacity. Option B is wrong because organizational culture affects adoption speed and change readiness, but it is not a resource that gets consumed by demand. Option D is wrong because strategic documentation is a planning output that guides direction but has no capacity limit that demand can exhaust.
