Given the following excerpt of a Dockerfile:
Run apt-get –y update andand apt-get install –y fortunes andand apt-get clean
Why are the multiple apt-get commands combined in one RUN statement instead of using multiple RUN statements?
A. To prevent the commands from running in parallel because Docker executes all RUN statements in their own container at the same time.
B. To ensure the execution order of the commands because Docker might evaluate the statements of a Dockerfile in any order.
C. To avoid the creation of unnecessary images because Docker creates a new image for each RUN statement.
D. To execute both commands in the same container instance and void Docker to reset the container to the original base image.
E. To execute the apt-get install command only if the apt-get update command was successful because Docker does not check the success of RUN statements.
A Dockerfile contains the statements:
COPY data/ /data/ VOLUME /data
What happens when the resulting container is started without any additional volume configuration? (Choose two correct answers.)
A. Files existing in /data/ in the image are not available in the running container.
B. Changes to files within /data/ affect the Docker image and all other containers derived from it.
C. Existing files from /data/ in the image are copied to the new volume.
D. An error is raised because /data/ already contains data when the volume is mounted.
E. A new volume is created and mounted to /data/ within the new container.
What is the purpose of a .dockerignore file?
A. It specifies which parts of a Dockerfile should be ignored when building a Docker image.
B. It musr be placed in the top level directory of volumes that Docker should never attach automatically to a container.
C. It exists in the root file system of containers that should ignore volumes and ports provided by Docker.
D. It specifies files that Docker does not submit to the Docker aemon when building a Docker image.
E. It lists files existing in a Docker image which should be excluded when building a derivative image.

Leads4Pass is one of the best websites I have ever used. It only took me 3 days of preparation to complete my goal plan. Not only that, I was successful with high scores.

It was the 16th when I purchased the Leads4Pass materials. They updated the materials on the 18th. When I asked them to send me the latest materials, they quickly sent me the latest ones. The new materials included several of the latest core question types. Finally, I succeeded. Six of the new core questions were completely matched. Thank you!

I have used free materials, the privacy is poor, the public content matching rate is too low,I gave up on them because they failed me once. Leads4Pass was recommended by a friend. Both the privacy protection and the preciousness of the materials are very high. By the way, I won this time.

There is nothing more satisfying than success! Their question types are very similar, and they were very helpful to my progress in answering questions during the exam. Thank you.

I need to take multiple certification exams for my organization. There are so many certification exams that I can't help but choose supporting materials. I have tried multiple platforms with some success and failure. In the end, I chose Leads4Pass. It was instant for me. Effective materials are where the real value lies.

I was despised by a close friend until he failed twice and I passed once and then he changed his mind. He shared his failure experience with me. He told me that he had been learning through books and looking for free materials. These outdated contents could not really help him. Later I recommended him Leads4Passs and he also succeeded.

I was lucky enough to choose Leads4Pass for the first time. I used their VCE tool to learn, and it was really easy and efficient. I think what’s really amazing is that they can ensure that all materials are industry-leading, which is really amazing.
