Docker Certified Associate (DCA) Exam Sample Questions (Q132-Q137):

NEW QUESTION # 132
The following Docker Compose file is deployed as a stack:

Is this statement correct about this health check definition?
Solution: Health checks test for app health ten seconds apart. Three failed health checks transition the container into "unhealthy" status.

  • A. No
  • B. Yes

Answer: B


NEW QUESTION # 133
Is this a Linux kernel namespace that is disabled by default and must be enabled at Docker engine runtime to be used?
Solution: user

  • A. No
  • B. Yes

Answer: B

Explanation:
The user namespace is a Linux kernel namespace that is disabled by default and must be enabled at Docker engine runtime to be used. The user namespace allows the host system to map its own uid and gid to some different uid and gid for containers' processes. This improves the security of Docker by isolating the user and group ID number spaces, so that a process's user and group ID can be different inside and outside of a user namespace1. To enable the user namespace, the daemon must start with --userns-remap flag with a parameter that specifies base uid/gid2. All containers are run with the same mapping range according to /etc/subuid and /etc/subgid3. Reference:

NEW QUESTION # 134
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 them to a team in the engineering organization that has read/write access to the engineering/api repository.

  • A. Yes
  • B. No

Answer: B

Explanation:
= I cannot give you a comprehensive explanation, but I can tell you that the question is about Docker Trusted Registry (DTR), which is a secure and scalable image storage solution for Docker Enterprise1. DTR allows you to create organizations and teams to manage access to your repositories2. Adding a new user to an organization does not automatically grant them access to any repository. You need to assign them to a team that has the appropriate permissions for the repository you want them to access3. Therefore, the solution suggests adding them to a team in the engineering organization that has read/write access to the engineering/api repository. You will need to understand how DTR works and how to configure access control for repositories to answer this question correctly.

* Manage access to repositories


NEW QUESTION # 135
Which of the following is supported by control groups?

  • A. Limit CPU usage within a container
  • B. Manage certificates
  • C. Isolate processes in a container
  • D. Collect net

Answer: A


NEW QUESTION # 136
You want to create a container that is reachable from its host's network. Does this action accomplish this?
Solution: Use network attach to access the containers on the bridge network

  • A. Yes
  • B. No

Answer: B

Explanation:
Explanation
Using network attach to access the containers on the bridge network does not make the container reachable from its host's network. The network attach option connects a running container to another network, but it does not expose any ports to the host. To make a container reachable from its host's network, you need to use either EXPOSE or --publish to access the containers on the bridge network. References:
