350-401 Question 82
Single answerA network administrator is deploying a virtualized environment for a new branch office. The administrator wants to run multiple virtual machines directly on the server's hardware for better performance and isolation. Which type of hypervisor should the administrator choose, and why?
- A
Type 1 hypervisor, because it runs directly on the hardware without requiring a host operating system.
- B
Type 1 hypervisor, because it requires a lightweight host operating system to manage hardware resources.
- C
Type 2 hypervisor, because it runs directly on the hardware without requiring a host operating system.
- D
Type 2 hypervisor, because it runs on top of an existing operating system.
Show answer and explanation
Correct answer: A
Explanation
Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the hardware without a host operating system. This architecture provides superior performance, better resource utilization, and enhanced isolation for virtual machines, making it the ideal choice for environments requiring high efficiency. Type 2 hypervisors, on the other hand, run on top of a host operating system, which introduces additional overhead and is less suitable for scenarios prioritizing performance and isolation.
- A. Correct.
Correct: A Type 1 hypervisor is designed to run directly on the hardware, providing better performance and isolation without the need for a host operating system.
- B. Incorrect.
Incorrect: A Type 1 hypervisor does not require a host operating system and operates directly on the hardware, so this explanation is incorrect.
- C. Incorrect.
Incorrect: This statement is incorrect because a Type 2 hypervisor requires a host operating system to function and does not run directly on hardware.
- D. Incorrect.
Incorrect: While this correctly describes a Type 2 hypervisor, it is not the best choice for the given scenario where direct hardware access and performance are critical.
