Certified Information Systems Security Professional (CISSP) — Question 391

Which of the following virtual network configuration options is BEST to protect virtual machines (VM)?

Answer options

• A. Data segmentation
• B. Data encryption
• C. Traffic filtering
• D. Traffic throttling

Correct answer: C

Explanation

Traffic filtering is the best option to protect virtual machines as it controls the flow of traffic and can block unauthorized access. Data segmentation and encryption are important but do not directly manage the traffic that reaches the VMs. Traffic throttling is related to bandwidth management, which does not inherently provide security for the VMs.
