Docker Certified Associate (DCA) Exam Sample Questions (Q136-Q141):

NEW QUESTION # 136
Is this an advantage of multi-stage builds?
Solution: optimizes Images by copying artifacts selectively from previous stages

  • A. No
  • B. Yes

Answer: B

Explanation:
Explanation
Optimizing images by copying artifacts selectively from previous stages is an advantage of multi-stage builds.
Multi-stage builds allow you to use multiple FROM statements in your Dockerfile, each starting a new stage of the build. You can selectively copy artifacts from one stage to another, leaving behind everything you don't want in the final image. This reduces the size and complexity of your images, and improves security and performance. References: https://docs.docker.com/build/building/multi-stage/,
https://docs.docker.com/engine/reference/builder/#copy


NEW QUESTION # 137
Will this command ensure that overlay traffic between service tasks is encrypted?
Solution: docker service create --network --encrypted

  • A. No
  • B. Yes

Answer: A

Explanation:
= The command docker service create --network --encrypted will not ensure that overlay traffic between service tasks is encrypted. This is because the --network flag requires an argument that specifies the name or ID of the network to connect the service to1. The --encrypted flag is not a valid option for docker service create2. To encrypt overlay traffic between service tasks, you need to use the --opt encrypted flag on docker network create when you create the overlay network3. For example:
docker network create --opt encrypted --driver overlay my-encrypted-network Then, you can use the --network flag on docker service create to connect the service to the encrypted network.
For example:
docker service create --network my-encrypted-network my-service
References:
* docker service create | Docker Documentation
* docker service create | Docker Documentation
* Manage swarm service networks | Docker Docs
I hope this helps you understand the command and the encryption, and how they work with Docker and swarm. If you have any other questions related to Docker, please feel free to ask me.


NEW QUESTION # 138
You want to provide a configuration file to a container at runtime. Does this set of Kubernetes tools and steps accomplish this?
Solution: Turn the configuration file into a configMap object, use it to populate a volume associated with the pod, and mount that file from the volume to the appropriate container and path.

  • A. No
  • B. Yes

Answer: A

Explanation:
= Mounting the configuration file directly into the appropriate pod and container using the
.spec.containers.configMounts key is not a valid way to provide a configuration file to a container at runtime. The .spec.containers.configMounts key does not exist in the Kubernetes API1. The correct way to provide a configuration file to a container at runtime is to use a ConfigMap2. A ConfigMap is a Kubernetes object that stores configuration data as key-value pairs. You can create a ConfigMap from a file, and then mount the ConfigMap as a volume into the pod and container. The configuration file will be available as a file in the specified mount path3. Alternatively, you can also use environment variables to pass configuration data to a container from a ConfigMap4. References:
* PodSpec v1 core
* Configure a Pod to Use a ConfigMap
* Populate a Volume with data stored in a ConfigMap
* Define Container Environment Variables Using ConfigMap Data


NEW QUESTION # 139
Your organization has a centralized logging solution, such as Splunk.
Will this configure a Docker container to export container logs to the logging solution?
Solution: Set the log-driver and log-oPt keys to values for the logging solution (Splunk) In the daemon.json file.

  • A. No
  • B. Yes

Answer: B

Explanation:
Explanation
Setting the log-driver and log-opt keys to values for the logging solution (Splunk) in the daemon.json file will configure a Docker container to export container logs to the logging solution. This is because the Splunk logging driver sends container logs to the HTTP Event Collector in Splunk Enterprise and Splunk Cloud1. To use the Splunk driver as the default logging driver, set the keys log-driver and log-opts to appropriate values in the daemon.json configuration file and restart Docker1. To use the Splunk driver for a specific container, use the commandline flags --log-driver and log-opt with docker run1. The Splunk logging driver supports various options, such as splunk-token, splunk-url, splunk-source, splunk-sourcetype, splunk-index, etc1. References:
Splunk logging driver | Docker Docs1


NEW QUESTION # 140
Is this the purpose of Docker Content Trust?
Solution. Sign and verify image tags.

  • A. No
  • B. Yes

Answer: B

Explanation:
Explanation
Signing and verifying image tags is the purpose of Docker Content Trust. Docker Content Trust (DCT) is a feature that allows you to use digital signatures for data sent to and received from remote Docker registries.
These signatures allow client-side or runtime verification of the integrity and publisher of specific image tags.
With DCT, image publishers can sign their images and image consumers can ensure that the images they pull are signed. References: https://docs.docker.com/engine/security/trust/
