CompTIA A+ Core 1 (220-1101) — Question 327

Which of the following provides the highest level of isolation from the host operating system?

Answer options

• A. Type II hypervisor
• B. Resource pooling
• C. Hardware-assisted virtualization
• D. Single-node clustering

Correct answer: C

Explanation

Hardware-assisted virtualization (C) utilizes specific CPU features to create a virtual environment that operates independently from the host OS, ensuring maximum isolation. In contrast, a Type II hypervisor (A) runs on top of the host OS, which does not provide the same level of isolation. Resource pooling (B) focuses on aggregating resources rather than isolation, and single-node clustering (D) is more about redundancy than isolation from the host system.
