Answers
D.
System documentation not being updated to reflect changes in the environment
Suggested answer: A

Explanation:

The most significant risk in virtualizing the server environment without making any other changes to the network or security infrastructure is the inability of the network intrusion detection system (IDS) to monitor virtual server-to-server communications. This can create blind spots for the IDS and allow malicious traffic to bypass detection. A vulnerability in the virtualization platform affecting multiple hosts is a potential risk, but not necessarily more significant than the loss of visibility. Data center environmental controls not aligning with new configuration or system documentation not being updated to reflect changes in the environment are operational issues, not security issues.Reference:ISACA, CISA Review Manual, 27th Edition, 2018, page 373
