Kubernetes - Networking

Given this NetworkPolicy snippet, what traffic is allowed?

egress:
  - to:
    - ipBlock:
        cidr: 10.0.0.0/24
        except:
        - 10.0.0.5/32

AAll outgoing traffic to 10.0.0.0/24 except 10.0.0.5

BAll incoming traffic from 10.0.0.0/24 except 10.0.0.5

CAll outgoing traffic to 10.0.0.5 only

DAll incoming traffic from 10.0.0.5 only

Step-by-Step Solution

Solution:

Step 1: Analyze egress rule with ipBlock
The rule allows outgoing traffic to IPs in 10.0.0.0/24 except 10.0.0.5.
Step 2: Confirm direction and exceptions
Egress means outgoing traffic; 'except' excludes 10.0.0.5 from allowed IPs.
Final Answer:
All outgoing traffic to 10.0.0.0/24 except 10.0.0.5 -> Option A
Quick Check:
Egress with ipBlock except excludes IPs [OK]

Quick Trick: Egress 'to' with ipBlock allows excepted IPs blocked [OK]
