A.

Yes

Answers
A.

Yes

B.

No

Answers
B.

No

Suggested answer: B

Explanation:

: = The 'docker inspect' command returns low-level information on Docker objects, such as containers, images, networks, etc1It does not show the list of historical tasks for a service.To view the list of tasks for a service, you need to use the 'docker service ps' command2. For example, to see the tasks for the 'http' service, you would run 'docker service ps http'.This would show the ID, name, image, node, desired state, current state, and error of each task2.Reference:Docker inspect | Docker Docs,Docker service ps | Docker Docs
