Docker DCA Exam - Topic 6 Question 90 Discussion

Actual exam question for Docker's DCA exam
Question #: 90
Topic #: 6
[All DCA Questions]

Is this statement correct?

Solution: A Dockerfile stores the Docker daemon's configuration options.

Show Suggested Answer Hide Answer
Suggested Answer: A

The provided Kubernetes NetworkPolicy YAML configuration indicates that the policy applies to pods with the label tier: backend in the default namespace1. The ingress rule allows traffic from pods with the label tier: api1. Therefore, a request issued from a pod bearing only the tier: frontend label to a pod bearing the tier: backend label will be blocked by this networkPolicy1. This is because the networkPolicy does not have a rule allowing ingress from pods with the tier: frontend label1. For more information on Kubernetes NetworkPolicies, you can refer to the Kubernetes Documentation on Network Policies.

Yeah, Dockerfile is all about instructions for creating images!

Nope, definitely incorrect. The daemon has its own config files.

That's not right, a Dockerfile defines the image build process.

This sounds familiar, but I can't recall if the Docker daemon's settings are stored elsewhere. I might go with Yes just to be safe.

I think a Dockerfile is more about defining the environment for the application, not the daemon's config. So, I’m leaning towards No.

Ah, I know this one! Dockerfiles are for defining the build process of Docker images, not for storing the daemon's configuration. I'm pretty sure the correct answer here is "No".

I'm a bit confused by this question. I thought Dockerfiles were used to build images, but I could be misremembering some of the details around Docker configuration. I'll have to review my notes to be sure.

This statement is definitely wrong. Dockerfiles are for building images, not configuring the Docker daemon itself. I'm confident I know the difference between these two key Docker concepts.

Hmm, I'm a bit unsure about this one. I know Dockerfiles are used to define the build process for Docker images, but I can't recall if they store the daemon's configuration. I'll have to think this through carefully.

I think the answer might be to create a criteria-based sharing rule for the Quota object, using the ISCHANGED function on the Account Owner field. That way, the new account owner would automatically get access to the related Quota records.

I'm a bit unsure, but I think leaving the boot target definition empty might not work. Isn't that option C a risk if the system can't find the LUN?

This seems like a pretty straightforward access control issue. The network admin made a mistake in the firewall rule, allowing users to access Gmail when they shouldn't have.

I'm a bit confused about the timeline; are we calculating up to the end of March 2012 or just to the end of 2011? I hope that doesn't affect the cash in hand!
