Docker Exam DCA Topic 4 Question 102 Discussion

Actual exam question for Docker's DCA exam
Question #: 102
Topic #: 4
[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

Wait, are we sure this isn't a trick question? I mean, the image shows a networkPolicy, but the question asks about 'this trafftc'. Sounds fishy to me. I'm gonna play it safe and go with 'No'.

Ha, 'trafftc'? Looks like someone needs to brush up on their spelling. But I digress, I think the 'No' answer is the way to go here. The policy doesn't seem to be blocking that specific traffic.

Hold up, I'm not so sure about that. The question says the policy will 'BLOCK this trafftc', but the solution mentions a request from a pod with the 'tier: api' label to a pod with 'tier: backend' label. Shouldn't that be allowed? I'm gonna go with 'No'.

Hmm, this looks like a tricky one. I'm gonna go with 'Yes' on this one. The networkPolicy seems pretty straightforward to me.
