Certified Kubernetes Administrator (CKA) Program Exam certification is recognized by industry leaders, including AWS, Google Cloud, and Red Hat. Certified Kubernetes Administrator (CKA) Program Exam certification also provides access to a network of certified professionals and resources, including training, events, and community support. Overall, the CKA certification is an excellent way to demonstrate your expertise in Kubernetes and advance your career in the cloud-native ecosystem.   NO.21 List pod logs named “frontend” and search for the pattern “started” and write it to a file “/opt/error-logs” See the solution below.ExplanationKubectl logs frontend | grep -i “started” > /opt/error-logsNO.22 Score: 4%TaskSchedule a pod as follows:* Name: nginx-kusc00401* Image: nginx* Node selector: disk=ssd Solution:#yamlapiVersion: v1kind: Podmetadata:name: nginx-kusc00401spec:containers:– name: nginximage: nginximagePullPolicy: IfNotPresentnodeSelector:disk: spinning#kubectl create -f node-select.yamlNO.23 Delete the pod without any delay (force delete) Kubect1 delete po “POD-NAME” –grace-period=0 –forceNO.24 Create a snapshot of theetcdinstance running at , saving thesnapshot to the file path/srv/data/etcd-snapshot.db.The following TLScertificates/key are suppliedfor connecting to the server withetcdctl:* CA certificate:/opt/KUCM00302/ca.crt* Client certificate:/opt/KUCM00302/etcd-client.crt* Client key:Topt/KUCM00302/etcd-client.key See the solution below.ExplanationsolutionNO.25 Change the Image version back to 1.17.1 for the pod you just updated and observe the changes kubectl set image pod/nginx nginx=nginx:1.17.1 kubectl describe po nginx kubectl get po nginx -w # watch itNO.26 Verify certificate expiry date for ca certificate in /etc/kubernetes/pki openssl x509 -in ca.crt -noout -text | grep -i validity -A 4NO.27 Create a namespace called ‘development’ and a pod with image nginx called nginx on this namespace. kubectl create namespace development kubectl run nginx –image=nginx –restart=Never -n developmentNO.28 Score:7%ContextAn existing Pod needs to be integrated into the Kubernetes built-in logging architecture (e. g. kubectl logs).Adding a streaming sidecar container is a good and common way to accomplish this requirement.TaskAdd a sidecar container named sidecar, using the busybox Image, to the existing Pod big-corp-app. The new sidecar container has to run the following command:/bin/sh -c tail -n+1 -f /va r/log/big-corp-app.logUse a Volume, mounted at /var/log, to make the log file big-corp-app.log available to the sidecar container. See the solution below.ExplanationSolution:#kubectl get pod big-corp-app -o yaml#apiVersion: v1kind: Podmetadata:name: big-corp-appspec:containers:– name: big-corp-appimage: busyboxargs:– /bin/sh– -c– >i=0;while true;doecho “$(date) INFO $i” >> /var/log/big-corp-app.log;i=$((i+1));sleep 1;donevolumeMounts:– name: logsmountPath: /var/log– name: count-log-1image: busyboxargs: [/bin/sh, -c, ‘tail -n+1 -f /var/log/big-corp-app.log’]volumeMounts:– name: logsmountPath: /var/logvolumes:– name: logsemptyDir: {}#kubectl logs big-corp-app -c count-log-1NO.29 Which one is the correct configuration?  #Panorama  &Panorama  $Panorama  @Panorama NO.30 For this item, you will have to ssh to the nodes ik8s-master-0 and ik8s-node-0 and complete all tasks on these nodes. Ensure that you return to the base node (hostname: node-1) when you have completed this item.ContextAs an administrator of a small development team, you have been asked to set up a Kubernetes cluster to test the viability of a new application.TaskYou must use kubeadm to perform this task. Any kubeadm invocations will require the use of the–ignore-preflight-errors=all option.* Configure the node ik8s-master-O as a master node. .* Join the node ik8s-node-o to the cluster. See the solution below.ExplanationsolutionYou must use the kubeadm configuration file located at /etc/kubeadm.conf when initializingyour cluster.You may use any CNI plugin to complete this task, but if you don’t have your favourite CNI plugin’s manifest URL at hand, Calico is one popular option: https://docs.projectcalico.org/v3.14/manifests/calico.yaml Docker is already installed on both nodes and has been configured so that you can install the required tools.NO.31 Set the node named ek8s-node-1 as unavailable and reschedule all the pods running on it. solutionNO.32 Check nodes which are ready and print it to a file /opt/nodestatus  JSONPATH='{range .items[*]}{@.metadata.name}:{range@.status.conditions[*]}{@.type}={@.status};{end}{end}’ && kubectl get nodes -o jsonpath=”$JSONPATH” | grep“Ready=True” > /opt/node-status//Verifycat /opt/node-status  JSONPATH='{range .items[*]}{@.metadata.name}:{range@.status.conditions[*]}{@.type}={@.status};{end}{end}’ //Verifycat /opt/node-status NO.33 Create an nginx pod and list the pod with different levels of verbosity See the solution below.Explanation// create a podkubectl run nginx –image=nginx –restart=Never –port=80// List the pod with different verbositykubectl get po nginx –v=7kubectl get po nginx –v=8kubectl get po nginx –v=9NO.34 Create a pod named kucc8 with a single app container for each of thefollowing images running inside (there may be between 1 and 4 images specified):nginx + redis + memcached. See the solution below.ExplanationsolutionNO.35 Create a pod as follows:* Name:non-persistent-redis* container Image:redis* Volume with name:cache-control* Mount path:/data/redisThe pod should launch in thestagingnamespace and the volumemust notbe persistent. See the solution below.ExplanationsolutionNO.36 Score: 13%TaskA Kubernetes worker node, named wk8s-node-0 is in state NotReady. Investigate why this is the case, and perform any appropriate steps to bring the node to a Ready state, ensuring that any changes are made permanent. See the solution below.ExplanationSolution:sudo -isystemctl status kubeletsystemctl start kubeletsystemctl enable kubeletNO.37 Create a pod that having 3 containers in it?
