CKS Question #61: Real Exam Question with Answer & Explanation

Question

You must connect to the correct host (e.g., via `ssh cks000031`). You are required to implement NetworkPolicies controlling the traffic flow of existing Deployments across namespaces. Task: 1. First, create a NetworkPolicy named `deny-policy` in the `prod` namespace to block all ingress traffic. The `prod` namespace is labeled `env:prod`. 2. Next, create a NetworkPolicy named `allow-from-prod` in the `data` namespace to allow ingress traffic only from Pods in the `prod` namespace. The `data` namespace is labeled `env:data`. Do not modify or delete any namespaces or Pods. Only create the required NetworkPolicies.
