See the solution below  \nAnswer: A  \nsolution  \nVisit us at: [https://www.examsboost.com/test/cka](https://www.examsboost.com/test/cka)  \nStep 0: Set the correct Kubernetes context  \nIf you're given a specific context (k8s in this case), you must switch to it: kubectl config use-context k8s  \n⚠⚠ Skipping this can cause you to work in the wrong cluster/namespace and cost you marks. Step 1: Identify the namespace of the pod foo  \nFirst, check if foo is running in a specific namespace or in the default namespace. kubectl get pods--all-namespaces | grep foo  \nVisit us at: [https://www.examsboost.com/test/cka](https://www.examsboost.com/test/cka)  \nAssume the pod is in the default namespace if no namespace is mentioned.  \nStep 2: Confirm pod foo exists and is running kubectl get pod foo  \nYou should get output similar to:  \nNAME READY STATUS RESTARTS AGE  \nfoo 1/1 Running 0 1h  \nIf the pod is not running, logs may not be available.  \nStep 3: View logs and filter specific error lines We’re looking for log lines that contain:  \nunable-to-access-website Command:  \nkubectl logs foo | grep \"unable-to-access-website\"Step 4: Write the filtered log lines to a file Redirect the output to the required path:  \nkubectl logs foo | grep \"unable-to-access-website\" > /opt/KULM00201/foo  \n✅ This creates or overwrites the file /opt/KULM00201/foo with the filtered logs.  \n✅ You may need sudo if /opt requires elevated permissions. But in most exam environments, you're already the root or privileged user.  \nStep 5: Verify the output file (optional but smart)  \nCheck that the file was created and has the correct content: cat /opt/KULM00201/foo  \n✅ Final Answer Summary: kubectl config use-context k8s  \nkubectl logs foo | grep \"unable-to-access-website\" > /opt/KULM00201/foo  \nSIMULATION  \nList all persistent volumes sorted by capacity, saving the full kubectl output to  \n/opt/KUCC00102/volume_list. Use kubectl 's own functionality for sorting the output, and do not manipulate it any further.  \nA. See the solution below  \nAnswer: A  \nsolution  \nVisit us at: [https://www.examsboost.com/test/cka](https://www.examsboost.com/test/cka)  \nSIMULATION  \nEnsure a single instance of pod nginx is running on each node of the Kubernetes cluster wherenginx also represents the Image name which has to be used. Do not override any taints currently in place.  \nUse DaemonSet to complete this task and use ds-kusc00201 as DaemonSet name.  \nA.
