NEW QUESTION # 15
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 # 16
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.
Answer:
Explanation:
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.
NEW QUESTION # 17
Backup and Restore - Restore Application from Existing Backup
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Make sure Velero is installed and configured in the environment.
The Task SIMULATION assumes an existing backup named backup-app-daily is already present.
Step 2: Run the restore command:
velero restore create --from-backup backup-app-daily
Step 3: Confirm the restore request is submitted.
The lab output shows:
Restore request "backup-app-daily-2024" submitted successfully.
Detailed explanation:
This command instructs Velero to create a restore operation using the existing backup called backup-app- daily. Velero is commonly used to protect Kubernetes and OpenShift resources by backing up object definitions and, when configured, persistent data integrations. The command does not manually recreate resources one by one; instead, it leverages the metadata captured during backup. A successful restore submission means the request has been accepted, not necessarily that every object has already been fully restored. In practical administration, you would often follow this by checking restore status and validating the application namespace, pods, services, routes, and storage bindings. This lab Task SIMULATION focuses specifically on initiating the restore from the named backup source.
NEW QUESTION # 18
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 # 19
Create and use a service account token via kubeconfig
Task Information : Create SA ci-bot in ci namespace and generate a kubeconfig that authenticates using its token.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Create namespace and service account
* oc new-project ci
* oc -n ci create sa ci-bot
* The SA will represent automation access.
* Grant permissions (example: edit in namespace)
* oc -n ci policy add-role-to-user edit system:serviceaccount:ci:ci-bot
* Without permissions, token auth succeeds but API actions are denied.
* Generate token (TokenRequest)
* TOKEN=$(oc -n ci create token ci-bot)
* OCP issues a short-lived token by default (good practice).
* Create kubeconfig using the token
* oc config set-cluster lab --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true --kubeconfig=ci-bot.kubeconfig
* oc config set-credentials ci-bot --token="$TOKEN" --kubeconfig=ci-bot.kubeconfig
* oc config set-context ci --cluster=lab --user=ci-bot --namespace=ci \
* --kubeconfig=ci-bot.kubeconfig
* oc config use-context ci --kubeconfig=ci-bot.kubeconfig
* This produces a self-contained kubeconfig for CI automation.
* Test access
* oc --kubeconfig=ci-bot.kubeconfig get pods
