- ReadOnlyMany

Collect Cluster Information
Task information Details:
Run must-gather and archive the gathered data into a tar file.
Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Run must-gather:
oc adm must-gather
* Confirm the directory created, usually something like:
ls
* Archive the directory:
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.
Use Secret in Monday Project
Task information Details:
Use the secret created earlier as environment variables in deployment monday .
Correct Answer:
See the solution below in Explanation.
Explanation:
Solution:
* Switch to the correct project if needed:
oc project monday
* Inject environment variables from the secret:
oc set env deployment/monday --from=secret/magic
* Verify:
oc set env deployment/monday --list
oc describe deployment monday
Notes:
* The uploaded lab references secret/file-secret, but Task 8 clearly intends the secret to be named magic .
* In a real exam, match the actual secret name present in the cluster.
This task tests secret consumption by workloads through environment variable injection.
