CompTIA Cloud+ Practice Test

Which of the following does not directly affect the hypervisor’s performance?

1. A. CPU architecture

2. B. Storage performance

3. C. Network speed

4. D. Number of client applications

The correct answer is: D. Number of client applications

The reason why the number of client applications does not directly affect the hypervisor's performance lies in the distinction between the hypervisor's function and the workloads it manages. A hypervisor is responsible for creating and managing virtual machines, including allocating resources such as CPU, memory, and storage. Its performance is primarily influenced by the underlying hardware and the efficiency of resource management rather than the number of applications running on the virtual machines. While more client applications may lead to increased resource demands and potentially impact overall system performance, the hypervisor itself manages these demands by allocating resources accordingly. This alleviates the direct impact on hypervisor performance. In contrast, CPU architecture, storage performance, and network speed are critical factors that do affect how effectively the hypervisor can operate. CPU architecture determines the computational capabilities, storage performance influences data access speed for virtual machines, and network speed affects how data is transmitted between virtual machines and external resources. Hence, the number of client applications is more of a user-defined aspect that relies on the existing performance capabilities of the hypervisor and the physical resources it has to work with, making it less impactful on the hypervisor’s performance compared to the other listed factors.
