NEW QUESTION # 16
Collect Cluster Information
Task information Details:
Run must-gather and archive the gathered data into a tar file.
Answer:
Explanation:
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.
NEW QUESTION # 17
Configure limits
Configure your OpenShift cluster to use limits in the bluebook project with the following requirements:
The name of the LimitRange resource is: ex280-limits
The amount of memory consumed by a single pod is between 5Mi and 300Mi The amount of memory consumed by a single container is between 5Mi and
300Mi with a default request value of 100Mi
The amount of CPU consumed by a single pod is between 10m and 500m
The amount of CPU consumed by a single container is between 10m and 500m with a default request value of
100m
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
Solution:
$ vim limit.yaml
# Edit the yaml file like below mentioned
apiVersion: "v1" kind: "LimitRange" metadata:
name: "resource-limits" spec:
limits:
- type: "Pod"
max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
- type: "Container" max:
cpu: "500m" memory: "300Mi"
min:
cpu: "10m" memory: "5Mi"
defaultRequest: cpu: "100m" memory: "100Mi"
$ oc create -f limit.yaml --save-config -n bluebook
$ oc describe limitranges -n bluebook
NEW QUESTION # 18
Use Secret in Monday Project
Task information Details:
Use the secret created earlier as environment variables in deployment monday .
Answer:
Explanation:
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.
NEW QUESTION # 19
