最新的 Red Hat OpenShift EX380 免費考試真題 (Q20-Q25):

問題 #20
Install OADP Operator and verify Velero components
Task Information : Install the OADP operator and confirm Velero pods/components are running.

答案：

解題說明：
See the solution below in Explanation:
Explanation:
* Install OADP via Web Console
* Operators # OperatorHub # search OADP / OpenShift API for Data Protection # Install
* Explanation: This operator manages Velero and backup integrations.
* Verify the operator CSV is installed
* oc get csv -A | grep -i -E "oadp|data protection|velero"
* Confirms installation succeeded.
* Verify pods in the OADP namespace (commonly openshift-adp)
* oc get pods -n openshift-adp
* You should see Velero/OADP-related pods in Running state.


問題 #21
Create a full application backup (resources + PV data)
Task Information : Create a Velero backup of namespace orders including PV snapshots.

答案：

解題說明：
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.


問題 #22
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.

答案：

解題說明：
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.


問題 #23
Create and use client certificates with kubeconfig (CSR flow)
Task Information : Generate a client key/CSR for audit2, approve it, extract the signed cert, and build a kubeconfig using that cert.

答案：

解題說明：
See the solution below in Explanation:
Explanation:
* Generate private key and CSR
* openssl genrsa -out audit2.key 2048
* openssl req -new -key audit2.key -out audit2.csr -subj "/CN=audit2/O=auditors"
* CN becomes username; O can map to groups in some setups.
* Base64 encode CSR for the API object
* CSR=$(base64 -w0 audit2.csr)
* Kubernetes CSR object expects base64-encoded request data.
* Create the CSR object
* cat < < EOF | oc apply -f -
* apiVersion: certificates.k8s.io/v1
* kind: CertificateSigningRequest
* metadata:
* name: audit2-csr
* spec:
* request: ${CSR}
* signerName: kubernetes.io/kube-apiserver-client
* usages:
* - client auth
* EOF
* Approve the CSR
* oc adm certificate approve audit2-csr
* Approval triggers certificate issuance.
* Extract the signed certificate
* oc get csr audit2-csr -o jsonpath='{.status.certificate}' | base64 -d > audit2.crt
* Produces the client certificate file.
* Build kubeconfig using cert/key
* oc config set-credentials audit2 \
* --client-certificate=audit2.crt --client-key=audit2.key \
* --embed-certs=true --kubeconfig=audit2.kubeconfig
* oc config set-cluster lab \
* --server="$(oc whoami --show-server)" \
* --insecure-skip-tls-verify=true \
* --kubeconfig=audit2.kubeconfig
* oc config set-context audit2 \
* --cluster=lab --user=audit2 --namespace=default \
* --kubeconfig=audit2.kubeconfig
* Creates a kubeconfig that authenticates using client certificates.
* Test
* oc --kubeconfig=audit2.kubeconfig get ns


問題 #24
Prevent workloads from running on dedicated nodes (taints)
Task Information : Apply a taint to dedicated nodes so only pods with tolerations can run there.

答案：

解題說明：
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.
