CKAD Application Observability and Maintenance Practice Question
Which kubectl command streams logs from a pod named 'web-pod' in real-time?
⚠ Common exam trap
Test-takers frequently confuse flags like `--tail` or `--since` with real-time streaming, not realizing that only `-f` (or `--follow`) provides continuous log output.

Correct answer & explanation
✓
kubectl logs -f web-pod
The `-f` flag (short for `--follow`) tells kubectl to stream logs from the pod in real-time, similar to `tail -f` on a file. This is essential for live monitoring of application output as it is generated.
