NEW QUESTION # 23
GitOps and MachineConfig - Push MachineConfig to Git
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Make sure the MachineConfig YAML has already been created or modified in the local Git repository.
This Task assumes the file change is ready to be committed.
Step 2: Run the command:
git commit -am "Add MachineConfig for motd" & & git push origin main
Step 3: Verify the commit succeeds and the push goes to the main branch.
The lab output shows:
[main 8d32a1] Add MachineConfig for motd
Detailed explanation:
This Task is part of a GitOps workflow. Instead of manually applying changes directly to the cluster, the desired configuration is stored in Git, and a GitOps controller such as Argo CD synchronizes the cluster to match the repository state. The command commits all tracked modified files with the message Add MachineConfig for motd and then pushes the change to the main branch. In this model, Git becomes the source of truth. A MachineConfig is typically used to manage node-level operating system configuration in OpenShift, so pushing it through GitOps ensures the change is auditable, repeatable, and reconciled declaratively. If the commit does not include the intended YAML, the synchronization mechanism will not apply the desired change.
NEW QUESTION # 24
Kubeconfig Management - Approve CSR
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Identify the pending certificate signing request.
The lab names it audit-csr.
Step 2: Run the approval command:
oc adm certificate approve audit-csr
Step 3: Confirm approval.
The lab output shows:
certificatesigningrequest.certificates.k8s.io/audit-csr approved
Detailed explanation:
In Kubernetes and OpenShift, a CSR must be approved before the requester can use the signed certificate for authentication. This Task approves the CSR named audit-csr, which is likely associated with the audit user or service account access flow in the lab. Certificate-based authentication is commonly used for kubeconfig access because it enables secure client identity without relying solely on tokens. Until the CSR is approved, the certificate cannot be trusted by the cluster API for authenticated operations. Administrative approval is therefore a gatekeeping step that ensures only intended certificate requests become valid credentials. This Task is part of a broader kubeconfig workflow that continues with setting credentials and defining context.
NEW QUESTION # 25
Silence an alert in Alertmanager
Task Information : Create an Alertmanager silence for a noisy alert for 2 hours, then confirm it's silenced.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Find the alert name and labels
* Web console: Observe # Alerts # click the alert to view label set.
* Open Alertmanager silences
* Observe # Alerting # Alertmanager # Silences # Create silence
* Explanation: Silences mute alerts matching label filters.
* Create the silence
* Add matcher: alertname = < ALERT_NAME >
* Duration: 2 hours
* Save.
* Verify the alert shows as silenced
* The alert should indicate it is silenced in the UI.
NEW QUESTION # 26
Backup and Restore - Fix SCC for Restored Application
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Identify the application namespace after restore.
The lab shows the namespace as my-app-namespace.
Step 2: Run the SCC assignment command:
oc adm policy add-scc-to-user anyuid -z default -n my-app-namespace
Step 3: Confirm the role binding is applied.
The lab output shows:
clusterrole.rbac.authorization.k8s.io/system:openshift:scc:anyuid added: "default" Detailed explanation:
After a restore, the application may fail if its pods require a security context not permitted by the default SCC allocation. This command grants the anyuid SCC to the default service account in the my-app-namespace project. The -z default syntax targets the default service account, which many restored workloads use if no custom service account is defined. The anyuid SCC allows containers to run with arbitrary user IDs, which some legacy or prebuilt images require. In OpenShift, SCC mismatches commonly cause pods to remain in pending or crash-related states. Assigning the proper SCC resolves those admission issues so workloads can start successfully. This step is therefore a post-restore operational fix to align security policy with application requirements.
NEW QUESTION # 27
Add tolerations to a deployment
Task Information : Update payments/api deployment to tolerate dedicated=payments:NoSchedule.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Patch deployment with toleration
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"tolerations":[
* {"key":"dedicated","operator":"Equal","value":"payments","effect":"NoSchedule"}
* ]}}}
* }'
* Toleration allows pods to schedule onto tainted nodes.
* Verify scheduling
* oc -n payments get pods -o wide
