Docker Certified Associate (DCA) Exam Sample Questions (Q170-Q175):

NEW QUESTION # 170
You created a new service named 'http* and discover it is not registering as healthy. Will this command enable you to view the list of historical tasks for this service?
Solution. 'docker inspect http"

  • A. Yes
  • B. No

Answer: B

Explanation:
Explanation
The command docker inspect http will not enable you to view the list of historical tasks for the service. The docker inspect command returns low-level information on Docker objects, such as containers, images, networks, or volumes1. It does not work on services, which are higher-level objects that define the desired state of a set oftasks2. To view the list of historical tasks for a service, you need to use the docker service ps command, which shows the current and previous states of each task, as well as the node, error, and ports3.

* Services | Docker Docs
* docker service ps | Docker Docs


NEW QUESTION # 171
Will this command ensure that overlay traffic between service tasks is encrypted?
Solution: docker service create --network --secure

  • A. Yes
  • B. No

Answer: B


NEW QUESTION # 172
A company's security policy specifies that development and production containers must run on separate nodes in a given Swarm cluster. Can this be used to schedule containers to meet the security policy requirements?
Solution.environment variables

  • A. Yes
  • B. No

Answer: B

Explanation:
Environment variables cannot be used to schedule containers to meet the security policy requirements. Environment variables are used to pass configuration data to the containers, not to control where they run1. To schedule containers to run on separate nodes in a Swarm cluster, you need to use node labels and service constraints23. Node labels are key-value pairs that you can assign to nodes to organize them into groups4. Service constraints are expressions that you can use to limit the nodes where a service can run based on the node labels. For example, you can label some nodes as env=dev and others as env=prod, and then use the constraint --constraint node.labels.env==dev or --constraint node.labels.env==prod when creating a service to ensure that it runs only on the nodes with the matching label.

NEW QUESTION # 173
An application image runs in multiple environments, with each environment using different certificates and ports. Is this a way to provision configuration to containers at runtime?
Solution.Create a Dockerfile for each environment, specifying ports and Docker secrets for certificates.

  • A. Yes
  • B. No

Answer: B

Explanation:
Explanation
Creating a Dockerfile for each environment, specifying ports and Docker secrets for certificates is not a way to provision configuration to containers at runtime. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image1. A Dockerfile is used to build an image, not to run a container. Once an image is built, the configuration specified in the Dockerfile cannot be changed at runtime. To provision configuration to containers at runtime, you need to use a different mechanism, such as environment variables, command-line arguments, or config maps234. References:

* Environment variables in Compose | Docker Docs
* Override the default command | Docker Docs
* Configuration management with Containers | Kubernetes


NEW QUESTION # 174
Is this an advantage of multi-stage builds?
Solution.better logical separation of Dockerfile instructions for increased readability

  • A. No
  • B. Yes

Answer: B

Explanation:
= Multi-stage builds allow you to use multiple FROM statements in your Dockerfile, each starting a new stage of the build1. This can help you achieve better logical separation of Dockerfile instructions for increased readability, as well as other benefits such as smaller image size, faster build time, and reduced security risks23. By separating your Dockerfile into different stages, you can organize your instructions by their purpose, such as building, testing, or deploying your application. You can also copy only the artifacts you need from one stage to another, leaving behind the unnecessary dependencies or tools1. This can make your Dockerfile easier to read and maintain, as well as improve the performance and security of your final image. Reference:
