질문 # 31
Kubeconfig Management - Approve CSR
정답：
설명：
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.
질문 # 32
Configure and synchronize OpenShift groups from LDAP (group sync)
Task Information : Create an LDAP group-sync config, run a one-time sync, and confirm groups exist in OpenShift.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Create a group sync config file (example groupsync.yaml)
* This file defines how OpenShift queries LDAP for groups and members.
* Run a one-time group sync
* oc adm groups sync --sync-config=groupsync.yaml --confirm
* --confirm actually applies changes (without it, it's a dry-run preview).
* Verify groups created/updated
* oc get groups
* oc describe group < groupname >
* Confirms group objects exist and membership is present.
질문 # 33
Create a full application backup (resources + PV data)
Task Information : Create a Velero backup of namespace orders including PV snapshots.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Confirm resources and PVCs exist
* oc -n orders get all
* oc -n orders get pvc
* Ensures there is something meaningful to back up.
* Create backup including volume snapshots
* velero backup create orders-full --include-namespaces orders --snapshot-volumes
* Captures Kubernetes objects and requests PV snapshots where supported.
* Check status/details
* velero backup describe orders-full --details
* velero backup logs orders-full
* Review warnings/errors and confirm snapshot actions.
질문 # 34
Backup and Restore - Restore Application from Existing Backup
정답：
설명：
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.
질문 # 35
Dedicate nodes to a workload using labels and nodeSelector
Task Information : Label two nodes with workload=payments and schedule a deployment only onto those nodes.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Label the chosen worker nodes
* oc label node worker-1 workload=payments
* oc label node worker-2 workload=payments
* Node labels are key/value metadata used by the scheduler.
* Add a nodeSelector to the deployment
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"nodeSelector":{"workload":"payments"}}}}
* }'
* Forces pods to schedule only to nodes that match the label.
* Verify placement
* oc -n payments get pods -o wide
* Confirms pods are running on the intended nodes.
