Certificate of Cloud Security Knowledge (CCSK) — Question 104

How can virtual machine communications bypass network security controls?

Answer options

• A. VM communications may use a virtual network on the same hardware host
• B. The guest OS can invoke stealth mode
• C. Hypervisors depend upon multiple network interfaces
• D. VM images can contain rootkits programmed to bypass firewalls
• E. Most network security systems do not recognize encrypted VM traffic

Correct answer: A

Explanation

The correct answer is A because virtual machines can communicate over a virtual network that operates on the same physical hardware, thereby avoiding external network security controls. The other options either describe capabilities that do not directly relate to bypassing security controls or involve scenarios that are less common or effective in evading detection.
