Selected Answer: B
A key feature of a container network is to enable communication between containers running on separate hosts. This is essential for distributed applications where different components of the application may be running on different nodes in a cluster. Container networks provide the necessary infrastructure to ensure that containers can discover and communicate with each other across the network, regardless of the physical host they are running on.
