質問 # 23
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.

Deploy Event Router and capture Kubernetes events in logging
Task Information : Deploy an event router so Kubernetes events are recorded as logs, then trigger events and confirm they appear in logging queries.
正解：
解説：
See the solution below in Explanation:
* Deploy event router resources
* Apply a deployment/serviceaccount/rolebinding manifest for eventrouter:
* oc apply -f eventrouter.yaml -n openshift-logging
* Eventrouter watches event API and writes them to stdout (collected by logging).
* Verify eventrouter pod is running
* oc -n openshift-logging get pods | grep -i event
* Trigger some events
* oc -n default run evtest --image=busybox --restart=Never -- sleep 1
* oc -n default delete pod evtest
* Creation/deletion generates events.
* Query logs for events
* In the logging UI/backend, search for the namespace/pod name evtest or eventrouter messages.
* Explanation: Validates that events are being converted to searchable logs.
質問 # 25
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 # 26
Kubeconfig Management - Use Context
正解：
解説：
See the solution below in Explanation:
Explanation:
Step 1: Make sure the context already exists in the kubeconfig file.
This follows the context creation Task SIMULATION .
Step 2: Run the command:
oc config use-context audit --kubeconfig audit.config
Step 3: Confirm the active context switches successfully.
The lab output shows:
Switched to context "audit".
Detailed explanation:
This command activates the audit context inside the specified kubeconfig file. Once selected, subsequent oc commands using that kubeconfig will default to the cluster, user, and namespace associated with that context.
This is operationally important because many administration mistakes come from running commands against the wrong cluster or project. Using explicit context switching reduces that risk and makes the kubeconfig usable for the intended audit workflow. In exams and real environments alike, the context is what turns separate kubeconfig elements into a working session configuration. Without switching to the correct context, even a well-formed kubeconfig may not be used as expected.
質問 # 27
Kubeconfig Management - Approve CSR
正解：
解説：
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.
