Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 488

What is a characteristic of para-virtualization?

Answer options

• A. Para-virtualization allows the host hardware to be directly accessed.
• B. Para-virtualization guest servers are unaware of one another.
• C. Para-virtualization lacks support for containers.
• D. Para-virtualization allows direct access between the guest OS and the hypervisor.

Correct answer: D

Explanation

The correct answer is D because para-virtualization allows the guest operating system to communicate directly with the hypervisor, improving performance. Option A is incorrect as para-virtualization does not provide direct access to host hardware. Option B is misleading since knowledge of other guest servers can depend on the configuration. Option C is wrong because para-virtualization can support containers, although it's not its primary function.
