You want to create a container that is reachable from its host's network.

Does this action accomplish this?

Solution. Use network connect to access the container on the bridge network.

A.

Yes

Answers
A.

Yes

B.

No

Answers
B.

No

Suggested answer: B

Explanation:

Using network connect to access the container on the bridge network does not accomplish creating a container that is reachable from its host's network.The network connect command connects a container to an existing network, but it does not expose the container's ports to the host1.The bridge network is the default network that Docker creates for containers, and it provides isolation from the host network2.To create a container that is reachable from its host's network, you need to use the host network driver, which disables network isolation and uses the host's network stack directly3.Alternatively, you can use the port mapping feature to publish specific ports of the container to the host4.Reference:
