Docker Certified Associate (DCA) Exam Sample Questions (Q46-Q51):

NEW QUESTION # 46
Will this command display a list of volumes for a specific container?
Solution:docker volume inspect nginx'

A. Yes
B. No

Answer: B

Explanation:
Explanation
= The command docker volume inspect nginx will not display a list of volumes for a specific container. This is because docker volume inspect expects one or more volume names as arguments, not a container name1. To display a list of volumes for a specific container, you can use the docker inspect command with the --format option and a template that extracts the volume information from the container JSON output2. For example, to display the source and destination of the volumes mounted by the container nginx, you can use the following command:
docker inspect --format=' { {range .Mounts}} { {.Source}}: { {.Destination}} { {end}}' nginx References:

NEW QUESTION # 47
In the context of a swarm mode cluster, does this describe a node?
Solution: an instance of the Docker engine participating in the swarm

A. No
B. Yes

Answer: B

Explanation:
Explanation
In the context of a swarm mode cluster, an instance of the Docker engine participating in the swarm is indeed a node1. A node can be either a manager or a worker, depending on the role assigned by the swarm manager2. A manager node handles the orchestration and management of the swarm, while a worker node executes the tasks assigned by the manager2. A node can join or leave a swarm at any time, and the swarm manager will reconcile the desired state of the cluster accordingly1. References:

NEW QUESTION # 48
Will a DTR security scan detect this?
Solution: known vulnerabilities or exposures in binaries

A. No
B. Yes

Answer: B

NEW QUESTION # 49
You add a new user to the engineering organization in DTR.
Will this action grant them read/write access to the engineering/api repository?
Solution: Add the user directly to the list of users with read/write access under the repository's Permissions tab.

A. Yes
B. No

Answer: B

Explanation:
Explanation
Adding a new user to the engineering organization in DTR will not automatically grant them read/write access to the engineering/api repository. This is because the repository permissions are not inherited from the organization level, but are configured separately for each repository. Therefore, to grant read/write access to the new user, you need to add them directly to the list of users with read/write access under the repository's Permissions tab. References:
