Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
oc logs api-server-xyz --tail=50 -f
Why this is correct
--tail=50 restricts initial output to the last 50 lines, and -f follows the log stream.
- ✗
oc describe pod api-server-xyz --lines=50
Why it's wrong here
oc describe does not support log tailing flags.
- ✗
oc logs api-server-xyz --lines=50 --follow
Why it's wrong here
The correct flag is --tail=50, not --lines=50.
- ✗
oc tail api-server-xyz -n 50
Why it's wrong here
'oc tail' is not a valid OpenShift command.
