Topic #: 3
[All Docker Certified Associate Exam 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

Is it just me, or does this networkPolicy look like a bowl of spaghetti? I hope I can untangle this in time for the exam!

Wow, this Kubernetes stuff is getting complicated! I'm going to have to study that networkPolicy diagram more closely to figure out the correct answer.

Based on the diagram, it seems like the networkPolicy should block the traffic between the 'api' and 'backend' pods. I'm confident in this answer.

The networkPolicy looks comprehensive, but I'm not sure if it will block the traffic. I'd like to see the full configuration to understand the rules better.
