Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
spec.ingress
Why it's wrong here
Ingress rules are optional; an empty spec with an empty podSelector isolates a namespace entirely.
- ✓
metadata
Why this is correct
All Kubernetes objects require standard metadata (like name).
- ✗
spec.egress.to.ipBlock
Why it's wrong here
egress rules are optional in a network policy.
- ✗
metadata.namespace
Why it's wrong here
Namespace is specified at creation time or metadata, but podSelector is the core spec requirement.
- ✓
spec.podSelector
Why this is correct
podSelector determines which pods the network policy applies to.
