質問 # 33
Kubeconfig Management - Set Context in Kubeconfig
正解：
解説：
See the solution below in Explanation:
Explanation:
Step 1: Verify the cluster name, namespace, and user name that should be referenced.
The lab uses cluster api-ocp4-example-com:6443, namespace audit-ns, and user audit-sa.
Step 2: Run the command:
oc config set-context audit --cluster api-ocp4-example-com:6443 --namespace audit-ns --user audit-sa -- kubeconfig audit.config Step 3: Confirm context creation.
The lab output shows:
Context "audit" created.
Detailed explanation:
A kubeconfig context ties together three things: a cluster endpoint, a user identity, and optionally a default namespace. This Task creates a context named audit in the file audit.config. Contexts are useful because they simplify repeated administration by letting the user switch between prepared working environments instead of re-entering cluster and namespace details each time. The namespace portion is especially helpful for project- scoped operations, because commands run under that context default to the chosen namespace. Accuracy matters here: if the user name in the context does not match the credentials entry or the cluster name does not exist in the kubeconfig, the context will not function as intended.
質問 # 34
Service Accounts and RBAC - Grant Cluster Reader Role
正解：
解説：
See the solution below in Explanation:
Explanation:
Step 1: Confirm the service account exists in auth-audit.
It must exist before a role can be assigned to it.
Step 2: Run the command:
oc adm policy add-cluster-role-to-user cluster-reader system:serviceaccount:auth-audit:audit Step 3: Verify the binding is added.
The lab output shows:
clusterrole.rbac.authorization.k8s.io/cluster-reader added: "system:serviceaccount:auth-audit:audit" Detailed explanation:
This binds the cluster-reader cluster role to the audit service account. The full subject format system:
serviceaccount:namespace:name is required because OpenShift RBAC needs the exact service account identity. The cluster-reader role is broader than a project-scoped view role because it allows read-level access across cluster resources. This is appropriate for auditing or inspection use cases where the account must observe but not modify. The distinction between cluster roles and namespaced roles is important: cluster roles apply to non-namespaced resources and broad cluster visibility, while local roles are limited to individual projects. This Task is a classic RBAC operation that combines identity creation with controlled privilege assignment.
質問 # 35
Backup and Restore - Fix SCC for Restored Application
正解：
解説：
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.
質問 # 36
Create an Argo CD Application (OpenShift GitOps)
Task Information : Create an Argo CD Application that syncs from Git into namespace gitops-demo with automated sync enabled.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Create target namespace
* oc new-project gitops-demo
* Destination must exist (unless Argo is configured to auto-create).
* Create Application manifest
* apiVersion: argoproj.io/v1alpha1
* kind: Application
* metadata:
* name: demo-app
* namespace: openshift-gitops
* spec:
* project: default
* source:
* repoURL: https://git.example.com/org/repo.git
* targetRevision: main
* path: manifests/demo
* destination:
* server: https://kubernetes.default.svc
* namespace: gitops-demo
* syncPolicy:
* automated:
* prune: true
* selfHeal: true
* automated: enables auto sync.
* prune: removes deleted objects from Git.
* selfHeal: corrects drift.
* Apply Application
* oc apply -f demo-app.yaml
* Verify sync health
* oc -n openshift-gitops get application demo-app -o yaml | grep -i -E "sync|health" -n
* oc -n gitops-demo get all
質問 # 37
Recover a NotReady worker node (basic remediation workflow)
Task Information : Diagnose a NotReady worker node and restore it to Ready state using standard OpenShift admin workflow.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Identify failing node and status
* oc get nodes
* Confirms which node is NotReady.
* Inspect node conditions and events
* oc describe node < worker >
* Shows kubelet condition issues (network, disk pressure, runtime, etc.).
* Check MachineConfigPool state
* oc get mcp
* oc describe mcp worker
* If MCP is degraded, node may be stuck applying a config.
* Check node logs (kubelet)
* oc adm node-logs < worker > --path=kubelet.log
* Often reveals why node isn't reporting Ready.
* Remediate based on symptom
* Examples:
* If out of disk: free space, then verify kubelet recovers.
* If stuck MCO: investigate current/desired config and fix broken MachineConfig.
* If node cordoned/drained incorrectly: uncordon after remediation.
* oc adm uncordon < worker >
* Confirm node returns Ready
* oc get node < worker >
