• A. True
• B. False
• C. Not applicable
• D. Unknown

Answer: (A)

In a vSphere environment, a cluster is a group of ESXi hosts managed by vCenter that can share resources and be coordinated as a single entity. The important idea is that the hosts within a cluster can pool CPU, memory, and I/O resources and be managed collectively, allowing features like Distributed Resource Scheduler (DRS) and High Availability (HA) to operate across the entire group. Because the hosts are connected and managed together, they communicate in a way that enables this resource pooling and balanced workload distribution, which is exactly what “aggregating resources” refers to in practice. Therefore, the statement is correct: a vSphere cluster is a logical grouping of multiple ESXi hosts that can communicate with one another to allow aggregating resources. The other options don’t describe a defined construct in vSphere.
