Which CNM construct represents a collection of endpoints that have connectivity between them and can be used to implement features like Linux bridge or VLAN?

• A. Network
• B. Endpoint
• C. Sandbox
• D. Cloud Carrier

Answer: (A)

In CNM, a Network is the grouping that combines multiple endpoints so they can talk to each other. Endpoints are the individual attachment points that containers use to connect to that network, and the network’s driver—such as a Linux bridge—handles the actual forwarding between those endpoints. VLANs come into play as a way to segment traffic, with each network potentially mapped to a VLAN ID so only endpoints within the same VLAN can reach each other. The Sandbox is the container’s own network namespace that holds its IP and DNS details, not the group of connected endpoints itself. So the construct described as a collection of connected endpoints that can implement features like a Linux bridge or VLAN is a Network.
