View Answer

Answer: B

Explanation:

The networkPolicy shown in the image is a Kubernetes yaml file that describes a networkPolicy. This networkPolicy will not block traffic from a pod bearing the tier: backend label, to a pod bearing the tier: frontend label. This is because the networkPolicy is configured to allow ingress traffic from pods with the tier: backend label to pods with the tier: frontend label.
