VMware Data Center Virtualization Fundamentals — Question 24

After configuring Fault Tolerance for critical servers, an administrate notices that protected virtual machines run slower than usual. What is the reason for performance reduction of these virtual machines?

Answer options

• A. Hosts have lower bandwidth for Fault Tolerance logging.
• B. Virtual machines are usually slow after Fault Tolerance logging.
• C. The storage space on the host is low.
• D. Virtual machines are running memory intensive applications.

Correct answer: A

Explanation

The correct answer is A because when Fault Tolerance is enabled, it requires additional bandwidth for logging, which can reduce the available bandwidth for the virtual machines, leading to performance issues. Option B is incorrect as it suggests a general slowdown that is not necessarily related to Fault Tolerance. Option C is irrelevant to the performance issue described, and option D does not directly relate to Fault Tolerance but rather to the nature of the applications running on the virtual machines.
