Docker Certified Associate (DCA) Exam Sample Questions (Q181-Q186):

NEW QUESTION # 181
Some Docker images take time to build through a Continuous Integration environment. You want to speed up builds and take advantage of build caching.
Where should the most frequently changed part of a Docker image be placed in a Dockerfile?

  • A. at the bottom of the Dockerfile
  • B. in the ENTRYPOINT directive
  • C. at the top of the Dockerfile
  • D. after the FROM directive

Answer: A


NEW QUESTION # 182
Is this a type of Linux kernel namespace that provides container isolation?
Solution. Process ID

  • A. Yes
  • B. No

Answer: A

Explanation:
Process ID is a type of Linux kernel namespace that provides container isolation. Linux namespaces are a feature of the Linux kernel that isolate and virtualize system resources of a collection of processes1. Process ID namespace isolates the process ID number space, meaning that processes in different PID namespaces can have the same PID2. This allows each container to have its own init process with PID 1, which is the ancestor of all other processes in the container3. Process ID namespace also affects other identifiers, such as thread IDs, parent process IDs, and session IDs4.

NEW QUESTION # 183
You want to create a container that is reachable from its host's network. Does this action accomplish this?
Solution: Use --link to access the container on the bridge network.

  • A. No
  • B. Yes

Answer: A

Explanation:
= The action of using --link to access the container on the bridge network does not accomplish the goal of creating a container that is reachable from its host's network. The --link option allows you to connect containers that are running on the same network, but it does not expose the container's ports to the host1. To create a container that is reachable from its host's network, you need to use the --network host option, which attaches the container to the host's network stack and makes it share the host's IP address2. Alternatively, you can use the --publish or -p option to map the container's ports to the host's ports3.

NEW QUESTION # 184
Will this configuration achieve fault tolerance for managers in a swarm?
Solution: at least seven nodes in total

  • A. Yes
  • B. No

Answer: A


NEW QUESTION # 185
Are these conditions sufficient for Kubernetes to dynamically provision a persistentVolume, assuming there are no limitations on the amount and type of available external storage?
Solution: A default storageClass is specified, and subsequently a persistentVolumeClaim is created.

  • A. Yes
  • B. No

Answer: A

Explanation:
= The conditions are sufficient for Kubernetes to dynamically provision a persistentVolume, because they include a default storageClass and a persistentVolumeClaim. A storageClass defines which provisioner should be used and what parameters should be passed to that provisioner when dynamic provisioning is invoked. A persistentVolumeClaim requests a specific size, access mode, and storageClass for the persistentVolume. If a persistentVolume that satisfies the claim exists or can be provisioned, the persistentVolumeClaim is bound to that persistentVolume. A default storageClass means that any persistentVolumeClaim that does not specify a storageClass will use the default one. Therefore, the conditions in the question are enough to enable dynamic provisioning of storage volumes on-demand. Reference:
