Docker Exam DCA 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.

Haha, this is a classic trick question. Everyone knows a Dockerfile is for building images, not for configuring the daemon. 'No' is the right answer!

Hmm, I'm pretty sure a Dockerfile is for building Docker images, not managing the daemon. The answer must be 'No'.

No way, a Dockerfile is used to build Docker images, not store the daemon's configuration. This statement is definitely incorrect.

I think the correct answer is B) No because a Dockerfile is used to specify the steps needed to build a Docker image, not to store daemon configurations.
