As the old saying goes, practice is the only standard to testify truth. In other word, it has been a matter of common sense that pass rate of the DCA study materials is the most important standard to testify whether it is useful and effective for people to achieve their goal. We believe that you must have paid more attention to the pass rate of the DCA study materials. If you focus on the study materials from our company, you will find that the pass rate of our products is higher than other study materials in the market, yes, we have a 99% pass rate, which means if you take our the DCA Study Materials into consideration, it is very possible for you to pass your exam and get the related certification.

The DCA Exam covers a broad range of topics related to Docker, including containerization, image creation and management, orchestration, networking, security, and storage. Candidates are expected to be proficient in the use of Docker tools and technologies such as Docker Engine, Docker Compose, Docker Swarm, and Docker Hub. They are also expected to have a solid understanding of how Docker integrates with other technologies and platforms, such as Kubernetes, AWS, and Azure.

The DCA certification is intended for developers and system administrators who want to validate their Docker skills and knowledge. Docker Certified Associate (DCA) Exam certification is ideal for professionals who work with Docker in production environments and want to demonstrate their expertise to their employers and clients. The DCA certification is also suitable for professionals who want to advance their careers in the field of DevOps, cloud computing, and containerization.

Docker Certified Associate (DCA) exam is a certification program that measures the skills and knowledge of an individual in containerization using Docker. It is an online, proctored exam that is designed to test the candidate's ability to work with Docker containers, images, networks, and storage. DCA Exam is based on the latest version of Docker, ensuring that candidates are tested on the most up-to-date technology.

Docker Certified Associate (DCA) Exam Sample Questions (Q32-Q37):

NEW QUESTION # 32
During development of an application meant to be orchestrated by Kubernetes, you want to mount the /data directory on your laptop into a container.
Will this strategy successfully accomplish this?
Solution. Set containers. Mounts. hostBinding: /data in the container's specification.

A. No
B. Yes

Answer: A

Explanation:
Explanation
The strategy will not successfully accomplish mounting the /data directory on your laptop into a container.
The containers. Mounts. hostBinding: /data is not a valid syntax for specifying a bind mount in a Kubernetes container specification. According tothe Kubernetes documentation), the correct way to mount a host directory into a container is to use a hostPath volume, which takes a path parameter that specifies the location on the host. For example, to mount the /data directory on your laptop into a container at /var/data, you can use the following YAML snippet:
spec:
containers:
-name:my-container
image:my-image
volumeMounts:
-name:data-volume
mountPath:/var/data
volumes:
-name:data-volume
hostPath:
path:/data
References: Volumes), Use bind mounts)

NEW QUESTION # 33
You configure a local Docker engine to enforce content trust by setting the environment variable DOCKER_CONTENT_TRUST=1.
If myorg/myimage: 1.0 is unsigned, does Docker block this command?
Solution: docker service create myorg/myimage:1.0

A. No
B. Yes

Answer: B

Explanation:
Explanation
When content trust is enabled, Docker blocks any command that operates on unsigned images, such as docker service create. This is because Docker Content Trust (DCT) allows users to verify the integrity and publisher of specific image tags, using digital signatures stored on a Notary server. If an image tag is not signed, or the signature cannot be verified, Docker will refuse to pull, run, or build with that image. Therefore, if myorg/myimage:1.0 is unsigned, Docker will block the command docker service create myorg/myimage:1.0 and display an error message. References:

NEW QUESTION # 34
You want to create a container that is reachable from its host's network. Does this action accomplish this?
Solution: Use either EXPOSE or --publish to access the containers on the bridge network

A. No
B. Yes

Answer: B

NEW QUESTION # 35
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
Multi-stage builds are a feature of Docker that allows you to use multiple FROM statements in your Dockerfile. Each FROM statement creates a new stage of the build, which can use a different base image and run different commands. You can then copy artifacts from one stage to another, leaving behind everything you don't want in the final image. This optimizes the image size and reduces the attack surface by removing unnecessary dependencies and tools. For example, you can use a stage to compile your code, and then copy only the executable file to the final stage, which can use a minimal base image like scratch. This way, you don't need to include the compiler or the source code in the final image. References:

NEW QUESTION # 36
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. No
B. Yes

Answer: A

Explanation:
Explanation
Environment variables cannot be used to schedule containers to meet the security policy requirements.
Environment variables are key-value pairs that can be passed to containers when they are created or run.
Environment variables can be used to configure the behavior of the containerized application or provide runtime information, such as database credentials, API keys, etc. Environment variables do not affect how containers are scheduled on nodes in a swarm mode cluster. References:
