질문 # 43
Kubeconfig Management - Use Context
정답：
설명：
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.

Export and import container images (mirror to internal registry)
Task Information : Pull an image from an external registry, push it into the OpenShift internal registry, and update a deployment to use the mirrored image.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Log in to OpenShift internal registry
* oc registry login
* Allows podman to push to the internal registry.
* Pull external image
* podman pull docker.io/library/nginx:1.25
* Gets the image locally.
* Tag for internal registry destination
* podman tag nginx:1.25 image-registry.openshift-image-registry.svc:5000/orders/nginx:1.25
* Uses the cluster service DNS name (works inside cluster network).
* Push to internal registry
* podman push image-registry.openshift-image-registry.svc:5000/orders/nginx:1.25
* Update deployment to use internal image
* oc -n orders set image deploy/web web=image-registry.openshift-image-registry.svc:5000/orders/nginx:
1.25
* Verify rollout
* oc -n orders rollout status deploy/web
* oc -n orders get pods -o wide
질문 # 45
Spread replicas using podAntiAffinity
Task Information : Configure payments/api to prefer scheduling pods on different nodes.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Patch deployment with preferred podAntiAffinity
* oc -n payments patch deploy api --type=merge -p '{
* "spec":{"template":{"spec":{"affinity":{
* "podAntiAffinity":{
* "preferredDuringSchedulingIgnoredDuringExecution":[{
* "weight":100,
* "podAffinityTerm":{
* "labelSelector":{"matchLabels":{"app":"api"}},
* "topologyKey":"kubernetes.io/hostname"
* }
* }]
* }
* }}}}
* }'
* Encourages spread across nodes to reduce single-node impact.
* Verify spread
* oc -n payments get pods -o wide
질문 # 46
Configure log forwarding to an external endpoint
Task Information : Configure Cluster Logging to forward application logs to an external output using ClusterLogForwarder.
정답：
설명：
See the solution below in Explanation:
Explanation:
* Verify logging namespace and resources
* oc get ns openshift-logging
* oc -n openshift-logging get clusterlogforwarder
* ClusterLogForwarder configures pipelines and outputs.
* Create/Edit ClusterLogForwarder (example structure)
* Define an output (external system) and pipeline selecting application logs.
* Apply via YAML:
* oc -n openshift-logging apply -f clusterlogforwarder.yaml
* Validate collector pods are healthy
* oc -n openshift-logging get pods
* Forwarding relies on collectors (vector/fluentd depending config).
* Generate a test log line
* oc -n openshift-logging run logger --image=busybox --restart=Never -- /bin/sh -c 'echo hello- forwarding; sleep 5'
* This creates a known message to search in the external endpoint.
* Confirm logs arrive at destination
* Use your external system's query/search to confirm hello-forwarding.
질문 # 47
Kubeconfig Management - Set Context in Kubeconfig
정답：
설명：
See the solution below in Explanation:
Explanation:
Step 1: Verify the cluster name, namespace, and user name that should be referenced.
The lab uses cluster api-ocp4-example-com:6443, namespace audit-ns, and user audit-sa.
Step 2: Run the command:
oc config set-context audit --cluster api-ocp4-example-com:6443 --namespace audit-ns --user audit-sa -- kubeconfig audit.config Step 3: Confirm context creation.
The lab output shows:
Context "audit" created.
Detailed explanation:
A kubeconfig context ties together three things: a cluster endpoint, a user identity, and optionally a default namespace. This Task creates a context named audit in the file audit.config. Contexts are useful because they simplify repeated administration by letting the user switch between prepared working environments instead of re-entering cluster and namespace details each time. The namespace portion is especially helpful for project- scoped operations, because commands run under that context default to the chosen namespace. Accuracy matters here: if the user name in the context does not match the credentials entry or the cluster name does not exist in the kubeconfig, the context will not function as intended.
