Certificate of Cloud Security Knowledge (CCSK) — Question 204

Why do blind spots occur in a virtualized environment, where network-based security controls may not be able to monitor certain types of traffic?

Answer options

• A. The network stack is out of alignment
• B. Clouds do not occur in networked environments
• C. Traffic is undetectable in virtual machines
• D. Virtual machines may communicate with each other over a virtual network all on the same host rather than a physical network between servers
• E. None of the above

Correct answer: D

Explanation

The correct answer is D because in a virtualized environment, virtual machines can communicate directly over a virtual network, bypassing the physical network, which creates blind spots for traditional network-based security controls. Options A, B, and C are incorrect as they do not accurately describe the reasons for blind spots in virtualized environments.
