質問 # 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.

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 # 17
Identity Management - Create CA ConfigMap

正解：

解説：
See the solution below in Explanation:
Explanation:
Step 1: Ensure the certificate file rhds_ca.crt is available in your current working directory or use the correct path.
The Task requires creating a configmap from this CA certificate file.
Step 2: Run the command:
oc create configmap rhds-ca-config-map --from-file ca.crt=rhds_ca.crt -n openshift-config Step 3: Confirm the configmap is created.
The lab output shows:
configmap/rhds-ca-config-map created
Detailed explanation:
This creates a configmap named rhds-ca-config-map in the openshift-config namespace and maps the local file rhds_ca.crt to the key name ca.crt inside the configmap. This is important in external identity integration because OpenShift may need to trust a custom certificate authority when communicating with LDAP or another secured external service. By placing the certificate in a configmap, the authentication operator or related cluster configuration can reference it cleanly. The key name matters because many OpenShift resources expect a CA bundle key with a specific filename-like convention. If the file path is wrong, the command fails immediately. If the configmap name or key mapping is wrong, the authentication provider referencing it may not trust the external endpoint.


質問 # 18
Kubeconfig Management - Set Credentials in Kubeconfig

正解：

解説：
See the solution below in Explanation:
Explanation:
Step 1: Ensure the client certificate and private key files are available.
The lab uses audit.crt and tls.key.
Step 2: Run the command:
oc config set-credentials audit --client-certificate audit.crt --client-key tls.key --embed-certs --kubeconfig audit.config Step 3: Confirm the user entry is written.
The lab output shows:
User "audit" set.
Detailed explanation:
This command creates or updates the audit user entry inside the kubeconfig file audit.config. It points the user to a client certificate and private key, and the --embed-certs option stores certificate material directly inside the kubeconfig rather than only referencing external files. That makes the kubeconfig more portable because it can be moved and used without separately copying the certificate files, provided the embedded content is valid. In certificate-based authentication, the private key proves client possession while the certificate presents the approved identity. If the certificate and key do not match, authentication will fail. This step does not yet define what cluster or namespace the user works against; it only defines the credential identity.


質問 # 19
Resolve group synchronization conflicts (prune stale data)
Task Information : Run group sync with pruning to remove stale OpenShift group memberships that no longer exist in LDAP.

正解：

解説：
See the solution below in Explanation:
Explanation:
* Run group sync with prune controls
* oc adm groups sync --sync-config=groupsync.yaml --confirm --prune-whitelist=/tmp/whitelist.txt
* Prune removes stale memberships/groups, but whitelist protects selected groups from pruning.
* Verify group membership reflects LDAP
* oc describe group < groupname >
* Confirms removed users are no longer listed.


質問 # 20
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.
