Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 286

What is a benefit of a virtual machine when compared with a physical server?

Answer options

• A. Multiple virtual servers can be deployed on the same physical server without having to buy additional hardware.
• B. Virtual machines increase server processing performance.
• C. The CPU and RAM resources on a virtual machine cannot be affected by other virtual machines.
• D. Deploying a virtual machine is technically less complex than deploying a physical server.

Correct answer: A

Explanation

The correct answer is A because virtual machines allow for efficient use of hardware by hosting multiple instances on a single physical server, thus saving costs on additional hardware. Option B is incorrect as virtual machines may not inherently increase performance compared to physical servers. Option C is misleading because resource contention can occur between virtual machines. Option D is also not necessarily true, as deploying virtual machines can still involve complex configurations.
