CCNA: Cisco Certified Network Associate — Question 350

What identifies the functionality of virtual machines?

Answer options

• A. The hypervisor communicates on Layer 3 without the need for additional resources.
• B. Each hypervisor supports a single virtual machine and a single software switch.
• C. The hypervisor virtualizes physical components including CPU, memory, and storage.
• D. Virtualized servers run efficiently when physically connected to a switch that is separate from the hypervisor.

Correct answer: C

Explanation

The correct answer is C because the hypervisor's primary role is to virtualize physical hardware components like CPU, memory, and storage, allowing multiple virtual machines to run on a single physical machine. Options A and B are incorrect as they inaccurately describe the capabilities and limitations of hypervisors, while D is misleading since the physical connection to a separate switch is not a requirement for efficient virtualized server operation.
