Docker DCA Exam - Topic 4 Question 102 Discussion

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

Is this statement correct?

Solution: A Dockerfile provides instructions for building a Docker image

Show Suggested Answer Hide Answer

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
