NEW QUESTION # 40
Prevent workloads from running on dedicated nodes (taints)
Task Information : Apply a taint to dedicated nodes so only pods with tolerations can run there.
Answer:
Explanation:
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.
NEW QUESTION # 41
Install OADP Operator and verify Velero components
Task Information : Install the OADP operator and confirm Velero pods/components are running.
Answer:
Explanation:
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.
NEW QUESTION # 42
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.
Answer:
Explanation:
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
NEW QUESTION # 43
Kubeconfig Management - Use Context
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Make sure the context already exists in the kubeconfig file.
This follows the context creation Task SIMULATION .
Step 2: Run the command:
oc config use-context audit --kubeconfig audit.config
Step 3: Confirm the active context switches successfully.
The lab output shows:
Switched to context "audit".
Detailed explanation:
This command activates the audit context inside the specified kubeconfig file. Once selected, subsequent oc commands using that kubeconfig will default to the cluster, user, and namespace associated with that context.
This is operationally important because many administration mistakes come from running commands against the wrong cluster or project. Using explicit context switching reduces that risk and makes the kubeconfig usable for the intended audit workflow. In exams and real environments alike, the context is what turns separate kubeconfig elements into a working session configuration. Without switching to the correct context, even a well-formed kubeconfig may not be used as expected.
NEW QUESTION # 44
Configure BackupStorageLocation and VolumeSnapshotLocation
Task Information : Configure OADP/Velero storage locations and confirm they show as Available.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Create a secret for cloud credentials (S3-compatible example)
* oc -n openshift-adp create secret generic cloud-credentials \
* --from-file=cloud=/path/to/credentials
* Velero uses this secret to authenticate to object storage.
* Create/Update the DataProtectionApplication (DPA)
* Apply a DPA CR that defines:
* backupLocations (bucket, endpoint URL, region, etc.)
* snapshotLocations (if using snapshots)
* Verify BackupStorageLocation and SnapshotLocation
* velero backup-location get
* velero snapshot-location get
* Status should be Available, meaning storage config is valid.
