質問 # 12
Backup and Restore - Restore Application from Existing Backup
正解：
解説：
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.

Identity Management - Create HTPasswd Secret
正解：
解説：
See the solution below in Explanation:
Explanation:
Step 1: Open a terminal with oc access to the cluster.
This Task is CLI-driven and targets the openshift-config namespace.
Step 2: Run the command:
oc create secret generic rhds-ldap-secret --from-literal bindPassword=redhatocp -n openshift-config Step 3: Verify that the secret is created successfully.
The lab output shows:
secret/rhds-ldap-secret created
Detailed explanation:
This step creates a generic secret named rhds-ldap-secret in the openshift-config namespace. The secret stores a key called bindPassword with the value redhatocp. In an identity-provider or LDAP integration workflow, the bind password is used by OpenShift when connecting to the external directory service. Storing this value in a secret is the correct operational pattern because authentication material should not be embedded directly into configuration objects. The openshift-config namespace is specifically important because cluster authentication configuration commonly references secrets and configmaps from that namespace. If the secret name or key is wrong, the authentication configuration that depends on it may fail to validate or connect properly.
質問 # 14
Create a full application backup (resources + PV data)
Task Information : Create a Velero backup of namespace orders including PV snapshots.
正解：
解説：
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.
質問 # 15
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.
質問 # 16
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.
