Linux Foundation Certified Kubernetes Administrator (CKA) Program Exam Sample Questions (Q70-Q75):

NEW QUESTION # 70
You have a Deployment named 'web-app' running 3 replicas of a web server. You need to define a PodDisruptionBudget (PDB) that ensures at least 2 replicas of the 'web-app' are always available during a planned or unplanned disruption. Write the YAML definition for the PDB and explain how it helps to ensure availability.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. PDB YAML Definition:

2. Explanation: - 'apiVersion: policy/vl Specifies the API version for the PodDisruptionBudget resource. - 'kind: PodDisruptionBudget': Specifies the type of resource, which is a PodDisruptionBudget. - 'metadata.name: web-app-pdb': Sets the name of the PDB. - 'spec.selector.matchLabels: app: web-app': This selector targets the Pods labeled with 'app: web-app' , ensuring the PDB applies to the 'web-app' Deployment's Pods. - 'spec.minAvailable: 2: Specifies the minimum number of Pods (replicas) that must remain available during a disruption. In this case, at least 2 replicas of 'web-app' must be running. 3. How it ensures availability: - Planned Disruptions: If you need to perform a maintenance operation that requires taking down a Pod, the Kubernetes scheduler will not allow it if doing so would violate the PDB. For example, if you try to delete a Pod belonging to 'web-app' , the scheduler will prevent it because deleting it would reduce the available replicas below the 'minAvailable' threshold. - Unplanned Disruptions: In case of node failures, the PDB helps to protect the application by ensuring that the minimum required number of Pods remain running on other healthy nodes. 4. Implementation: - Apply the YAML using 'kubectl apply -f web-app-pdb.yamr 5. Verification: You can verify the PDB's effectiveness by trying to delete Pods or simulate a node failure. You should observe that the scheduler prevents actions that would violate the 'minAvailable' constraint.


NEW QUESTION # 71
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.
Context
As 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.
Task You 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.

Answer:

Explanation:
solution
You must use the kubeadm configuration file located at /etc/kubeadm.conf when initializing your 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 apt has been configured so that you can install the required tools.


NEW QUESTION # 72
Score: 7%

Task
Reconfigure the existing deployment front-end and add a port specification named http exposing port 80/tcp of the existing container nginx.
Create a new service named front-end-svc exposing the container port http.
Configure the new service to also expose the individual Pods via a NodePort on the nodes on which they are scheduled.

Answer:

Explanation:
See the solution below.
Explanation
Solution:
kubectl get deploy front-end
kubectl edit deploy front-end -o yaml
#port specification named http
#service.yaml
apiVersion: v1
kind: Service
metadata:
name: front-end-svc
labels:
app: nginx
spec:
ports:
- port: 80
protocol: tcp
name: http
selector:
app: nginx
type: NodePort
# kubectl create -f service.yaml
# kubectl get svc
# port specification named http
kubectl expose deployment front-end --name=front-end-svc --port=80 --tarport=80 --type=NodePort


NEW QUESTION # 73
You are working with a Kubernetes cluster that has been configured with RBAC. You need to create a deployment for a new application, but you are encountering permission issues. You have verified that your user account belongs to the "developers" group, which should have sufficient permissions to create deployments. However, you are receiving an error message indicating insufficient privileges.
Investigate the potential causes for the permission issue and provide solutions to resolve the problem.

NEW QUESTION # 74
Create a persistent volume with name app-data, of capacity 2Gi and access mode ReadWriteMany. The type of volume is hostPath and its location is /srv/app-data.

Answer:

Explanation:
Persistent Volume
A persistent volume is a piece of storage in a Kubernetes cluster. PersistentVolumes are a cluster-level resource like nodes, which don't belong to any namespace. It is provisioned by the administrator and has a particular file size. This way, a developer deploying their app on Kubernetes need not know the underlying infrastructure. When the developer needs a certain amount of persistent storage for their application, the system administrator configures the cluster so that they consume the PersistentVolume provisioned in an easy way.
Creating Persistent Volume
kind: PersistentVolume
apiVersion: v1
metadata:
name:app-data
spec:
capacity: # defines the capacity of PV we are creating
storage: 2Gi #the amount of storage we are tying to claim
accessModes: # defines the rights of the volume we are creating
- ReadWriteMany
hostPath:
path: "/srv/app-data" # path to which we are creating the volume
Challenge
* Create a Persistent Volume named app-data, with access mode ReadWriteMany, storage classname shared, 2Gi of storage capacity and the host path /srv/app-data.

2. Save the file and create the persistent volume.
Image for post

3. View the persistent volume.

* Our persistent volume status is available meaning it is available and it has not been mounted yet. This status will change when we mount the persistentVolume to a persistentVolumeClaim.
PersistentVolumeClaim
In a real ecosystem, a system admin will create the PersistentVolume then a developer will create a PersistentVolumeClaim which will be referenced in a pod. A PersistentVolumeClaim is created by specifying the minimum size and the access mode they require from the persistentVolume.
Challenge
* Create a Persistent Volume Claim that requests the Persistent Volume we had created above. The claim should request 2Gi. Ensure that the Persistent Volume Claim has the same storageClassName as the persistentVolume you had previously created.
kind: PersistentVolume
apiVersion: v1
metadata:
name:app-data
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 2Gi
storageClassName: shared
2. Save and create the pvc
njerry191@cloudshell:~ (extreme-clone-2654111)$ kubect1 create -f app-data.yaml persistentvolumeclaim/app-data created
3. View the pvc
Image for post

4. Let's see what has changed in the pv we had initially created.
Image for post

Our status has now changed from available to bound.
5. Create a new pod named myapp with image nginx that will be used to Mount the Persistent Volume Claim with the path /var/app/config.
Mounting a Claim
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
name: app-data
spec:
volumes:
- name:congigpvc
persistenVolumeClaim:
claimName: app-data
containers:
- image: nginx
name: app
volumeMounts:
- mountPath: "/srv/app-data "
name: configpvc
