Answer:
Explanation:
See the solution below in Explanation.
Explanation:

tar -cvzf system10-4ktjl-l4kj5l-lk45j.tar.gz must-gather.local.*
* Verify:
ls -lh *.tar.gz
Notes:
* The lab text shows a tar command without source paths. A valid tar command must include the source directory or files.
* Use the actual must-gather output directory generated in your environment.
This task validates support-data collection and cluster diagnostics handling.
