Kubernetes and Cloud Native Associate (KCNA) — Question 172

What is a key feature of a container network?

Answer options

• A. Proxying REST requests across a set of containers.
• B. Allowing containers running on separate hosts to communicate.
• C. Allowing containers on the same host to communicate.
• D. Caching remote disk access.

Correct answer: B

Explanation

The correct answer is B because a container network enables communication between containers that are located on different hosts, which is essential for distributed applications. Options A and C pertain to specific functionalities within networks but do not define the key feature of container networking. Option D is unrelated, as it focuses on disk access rather than network communication.
