NEW QUESTION # 24
Kubeconfig Management - Approve CSR
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
Step 1: Identify the pending certificate signing request.
The lab names it audit-csr.
Step 2: Run the approval command:
oc adm certificate approve audit-csr
Step 3: Confirm approval.
The lab output shows:
certificatesigningrequest.certificates.k8s.io/audit-csr approved
Detailed explanation:
In Kubernetes and OpenShift, a CSR must be approved before the requester can use the signed certificate for authentication. This Task approves the CSR named audit-csr, which is likely associated with the audit user or service account access flow in the lab. Certificate-based authentication is commonly used for kubeconfig access because it enables secure client identity without relying solely on tokens. Until the CSR is approved, the certificate cannot be trusted by the cluster API for authenticated operations. Administrative approval is therefore a gatekeeping step that ensures only intended certificate requests become valid credentials. This Task is part of a broader kubeconfig workflow that continues with setting credentials and defining context.
NEW QUESTION # 25
Identity Management - Create CA ConfigMap
Answer:
Explanation:
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.
NEW QUESTION # 26
Recover a NotReady worker node (basic remediation workflow)
Task Information : Diagnose a NotReady worker node and restore it to Ready state using standard OpenShift admin workflow.
Answer:
Explanation:
See the solution below in Explanation:
Explanation:
* Identify failing node and status
* oc get nodes
* Confirms which node is NotReady.
* Inspect node conditions and events
* oc describe node < worker >
* Shows kubelet condition issues (network, disk pressure, runtime, etc.).
* Check MachineConfigPool state
* oc get mcp
* oc describe mcp worker
* If MCP is degraded, node may be stuck applying a config.
* Check node logs (kubelet)
* oc adm node-logs < worker > --path=kubelet.log
* Often reveals why node isn't reporting Ready.
* Remediate based on symptom
* Examples:
* If out of disk: free space, then verify kubelet recovers.
* If stuck MCO: investigate current/desired config and fix broken MachineConfig.
* If node cordoned/drained incorrectly: uncordon after remediation.
* oc adm uncordon < worker >
* Confirm node returns Ready
* oc get node < worker >
NEW QUESTION # 27
Add tolerations to a deployment
Task Information : Update payments/api deployment to tolerate dedicated=payments:NoSchedule.
Answer:
Explanation:
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
NEW QUESTION # 28
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
