Kubernetes - Networking

Given this NetworkPolicy snippet, what will be the effect on pod traffic? ```yaml apiVersion: networking.k8s.io/v1 kind: NetworkPolicy metadata: name: allow-web-egress spec: podSelector: matchLabels: role: web policyTypes: - Egress egress: - to: - ipBlock: cidr: 10.0.0.0/24 ports: - protocol: TCP port: 80 ```

APods with label role=web can send traffic to any IP and port

BPods with label role=web can only send TCP traffic to port 80 in 10.0.0.0/24

CPods with label role=web can only receive traffic on port 80

DPods with label role=web are blocked from all egress traffic

Step-by-Step Solution

Solution:

Step 1: Analyze podSelector and policyTypes
The policy applies to pods labeled role=web and controls egress traffic only.
Step 2: Interpret egress rules
Egress allows TCP traffic on port 80 only to IPs in 10.0.0.0/24 subnet.
Final Answer:
Pods with label role=web can only send TCP traffic to port 80 in 10.0.0.0/24 -> Option B
Quick Check:
Egress restricted to TCP port 80 in subnet [OK]

Quick Trick: Egress rules restrict outbound traffic by IP and port [OK]

Common Mistakes:

Confusing egress with ingress rules
Assuming open traffic to all IPs
Thinking it controls incoming traffic
