質問 # 38
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.

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.
質問 # 40
Configure resiliency using a PodDisruptionBudget
Task Information : Ensure at least 2 replicas of payments/api remain available during voluntary disruptions.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Create PDB
* cat < < EOF | oc -n payments apply -f -
* apiVersion: policy/v1
* kind: PodDisruptionBudget
* metadata:
* name: api-pdb
* spec:
* minAvailable: 2
* selector:
* matchLabels:
* app: api
* EOF
* minAvailable: 2 blocks evictions that would reduce availability below 2.
* Verify PDB
* oc -n payments get pdb
* oc -n payments describe pdb api-pdb
質問 # 41
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 # 42
Integrate OpenShift with LDAP (create LDAP identity provider)
Task Information : Configure cluster OAuth to add an LDAP identity provider using an existing bind secret and CA ConfigMap , then verify login works.
正解：
解説：
See the solution below in Explanation:
Explanation:
* Verify prerequisites exist (Secret + ConfigMap)
* oc -n openshift-config get secret rhds-ldap-secret
* oc -n openshift-config get configmap rhds-ca-config-map
* OAuth LDAP configuration references these objects. If they don't exist, OAuth won't be able to bind to LDAP securely.
* Edit the cluster OAuth resource
* oc edit oauth cluster
* The oauth/cluster resource is where identity providers are defined.
* Add an LDAP identity provider entry (example structure) Add under spec.identityProviders:
* - name: corp-ldap
* mappingMethod: claim
* type: LDAP
* ldap:
* url: "ldaps://ldap.example.com:636/ou=People,dc=example,dc=com?uid"
* bindDN: "uid=openshift,ou=svc,dc=example,dc=com"
* bindPassword:
* name: rhds-ldap-secret
* ca:
* name: rhds-ca-config-map
* insecure: false
* attributes:
* id: ["dn"]
* name: ["cn"]
* preferredUsername: ["uid"]
* email: ["mail"]
* url: where to search for users and which attribute is used for login (here uid).
* bindDN + bindPassword: service account used for LDAP queries.
* ca: trusts the LDAP server CA for TLS.
* attributes: maps LDAP data into OpenShift user identity fields.
* Restart OAuth pods to load changes quickly
* oc -n openshift-authentication delete pod -l app=oauth-openshift
* This forces pods to restart and re-read the updated configuration.
* Verify the identity provider appears and users can log in
* In the web console login page, you should see the new provider (name may show as corp-ldap).
* After a successful login, confirm user objects appear:
* oc get users
* oc get identities
* OpenShift creates User and Identity objects upon first successful authentication.
