質問 # 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.
正解：
解説：
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.
質問 # 33
Prevent workloads from running on dedicated nodes (taints)
Task Information : Apply a taint to dedicated nodes so only pods with tolerations can run there.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Taint nodes
* oc adm taint nodes worker-1 dedicated=payments:NoSchedule
* oc adm taint nodes worker-2 dedicated=payments:NoSchedule
* NoSchedule blocks new pods that do not tolerate the taint.
* Confirm taints
* oc describe node worker-1 | grep -i taints -A2
* Ensures taints are present.
* Validate effect
* A normal deployment without tolerations will remain Pending if it can only land on those tainted nodes.
質問 # 34
Add tolerations to a deployment
Task Information : Update payments/api deployment to tolerate dedicated=payments:NoSchedule.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Patch deployment with toleration
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"tolerations":[
* {"key":"dedicated","operator":"Equal","value":"payments","effect":"NoSchedule"}
* ]}}}
* }'
* Toleration allows pods to schedule onto tainted nodes.
* Verify scheduling
* oc -n payments get pods -o wide
質問 # 35
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 # 36
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.
