Docker Exam DCA Topic 5 Question 108 Discussion

Actual exam question for Docker's DCA exam
Question #: 108
Topic #: 5
[All DCA Questions]

The Kubernetes yaml shown below describes a networkPolicy.

Will the networkPolicy BLOCK this trafftc?

Solution. a request issued from a pod bearing the tier: api label, to a pod bearing the tier: backend label

Show Suggested Answer Hide Answer
Suggested Answer: B

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 the tier: api label to a pod bearing the tier: backend label will not be blocked by this networkPolicy1. This is because the networkPolicy explicitly allows ingress from pods with the tier: api label1. For more information on Kubernetes Network

I think the answer is B) No. The networkPolicy doesn't seem to have any rules that would block traffic from the 'api' pods to the 'backend' pods.

I agree with Audria, the networkPolicy seems to be configured to block the traffic.

But the solution mentions that it will block traffic between pods with specific labels.

Hmm, this looks like a trick question. The networkPolicy description doesn't specify the direction of the traffic, so I'm not sure if it will block the traffic or not.

I think it might block the traffic because it specifies the source and destination pods.
