CKA Free Exam Questions & Answers PDF Updated on Jul-2022 [Q18-Q41]

NO.18 A 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.
You can ssh to the failed node using:
[student@node-1] $ | ssh Wk8s-node-0
You can assume elevated privileges on the node with the following command:
[student@w8ks-node-0] $ | sudo -i

NO.19 Delete persistent volume and persistent volume claim

NO.20 Get the deployment rollout status

NO.21 Create a deployment as follows:
* Name: nginx-random
* Exposed via a service nginx-random
* Ensure that the service & pod are accessible via their respective DNS records
* The container(s) within any pod(s) running as a part of this deployment should use the nginx Image Next, use the utility nslookup to look up the DNS records of the service & pod and write the output to
/opt/KUNW00601/service.dns and /opt/KUNW00601/pod.dns respectively.

NO.22 Score: 4%

Task
Create a persistent volume with name app-data , of capacity 1Gi and access mode ReadOnlyMany. The type of volume is hostPath and its location is /srv/app-data .

NO.23 Get list of all the pods showing name and namespace with a jsonpath expression.

NO.24 A bootstrap USB flash drive has been prepared using a Windows workstation to load the initial configuration of a Palo Alto Networks firewall that was previously being used in a lab. The USB flash drive was formatted using file system FAT32 and the initial configuration is stored in a file named init-cfg.txt. The firewall is currently running PAN-OS 10.0 and using a lab config. The contents of init-cgf.txt in the USB flash drive are as follows:
type=dhcp-client
Ip-address=
default-gateway=
netmask=
Ipv6-address=
Ipv6-default-gateway=
hostname=Ca-FW-DC1
panorama-server=10.5.107.20
panorama-server-2=10.5.107.21
tplname=FINANCE_TG4
dgname=finance_dg
dns-primary=10.5.6.6
dns-secondary=10.5.6.7
op-command-modes-multi-vsys.jumbo-frame
dhcp-send-hostname=yes
dhcp-send-client-id=yes
dhcp-accept-server-hostname=yes
dhcp-accept-server-domain=yes
The USB flash drive has been inserted in the firewalls’ USB port, and the firewall has been restarted using command> request restart system Upon restart, the firewall fails to begin the bootstrapping process. The failure is caused because:

NO.25 Create a pod that echo “hello world” and then exists. Have the pod deleted automatically when it’s completed

NO.26 Create a hostPath PersistentVolume named task-pv-volume with storage 10Gi, access modes ReadWriteOnce, storageClassName manual, and volume at /mnt/data and verify

NO.27 Install a kubernetes cluster with one master and one worker using kubeadm

NO.28 An Administrator is configuring Authentication Enforcement and they would like to create an exemption rule to exempt a specific group from authentication. Which authentication enforcement object should they select?

NO.29 Check the Image version of nginx-dev pod using jsonpath

NO.30 List all persistent volumes sorted by capacity, saving the full kubectl output to
/opt/KUCC00102/volume_list. Use kubectl ‘s own functionality for sorting the output, and do not manipulate it any further.

NO.31 Score:7%

Task
Create a new PersistentVolumeClaim
* Name: pv-volume
* Class: csi-hostpath-sc
* Capacity: 10Mi
Create a new Pod which mounts the PersistentVolumeClaim as a volume:
* Name: web-server
* Image: nginx
* Mount path: /usr/share/nginx/html
Configure the new Pod to have ReadWriteOnce
Finally, using kubectl edit or kubectl patch PersistentVolumeClaim to a capacity of 70Mi and record that change.

NO.32 Given a partially-functioning Kubernetes cluster, identify symptoms of failure on the cluster.
Determine the node, the failing service, and take actions to bring up the failed service and restore the health of the cluster. Ensure that any changes are made permanently.
You can ssh to the relevant I nodes (bk8s-master-0 or bk8s-node-0) using:
[student@node-1] $ ssh <nodename>
You can assume elevated privileges on any node in the cluster with the following command:
[student@nodename] $ | sudo -i
