Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
Kubelet logs show node-level events, not API server authentication requests from external users.

The kube-proxy packet capture logs.
Why it's wrong here
Kube-proxy deals with service traffic routing, not API authentication.
- ✓
