Linux Foundation Certified Kubernetes Application Developer Exam Sample Questions (Q76-Q81):

NEW QUESTION # 76
Exhibit:

Context
A pod is running on the cluster but it is not responding.
Task
The desired behavior is to have Kubemetes restart the pod when an endpoint returns an HTTP 500 on the /healthz endpoint. The service, probe-pod, should never send traffic to the pod while it is failing. Please complete the following:
* The application has an endpoint, /started, that will indicate if it can accept traffic by returning an HTTP 200. If the endpoint returns an HTTP 500, the application has not yet finished initialization.
* The application has another endpoint /healthz that will indicate if the application is still working as expected by returning an HTTP 200. If the endpoint returns an HTTP 500 the application is no longer responsive.
* Configure the probe-pod pod provided to use these endpoints
* The probes should use port 8080

A. Solution:

In the configuration file, you can see that the Pod has a single Container. The periodSeconds field specifies that the kubelet should perform a liveness probe every 5 seconds. The initialDelaySeconds field tells the kubelet that it should wait 5 seconds before performing the first probe. To perform a probe, the kubelet executes the command cat /tmp/healthy in the target container. If the command succeeds, it returns 0, and the kubelet considers the container to be alive and healthy. If the command returns a non-zero value, the kubelet kills the container and restarts it.
When the container starts, it executes this command:
/bin/sh -c "touch /tmp/healthy; sleep 30; rm -rf /tmp/healthy; sleep 600"
For the first 30 seconds of the container's life, there is a /tmp/healthy file. So during the first 30 seconds, the command cat /tmp/healthy returns a success code. After 30 seconds, cat /tmp/healthy returns a failure code.
Create the Pod:
kubectl apply -f https://k8s.io/examples/pods/probe/exec-liveness.yaml
Within 30 seconds, view the Pod events:
kubectl describe pod liveness-exec
The output indicates that no liveness probes have failed yet:
FirstSeen LastSeen Count From SubobjectPath Type Reason Message
--------- -------- ----- ---- ------------- -------- ------ -------
24s 24s 1 {default-scheduler } Normal Scheduled Successfully assigned liveness-exec to worker0

After 35 seconds, view the Pod events again:
kubectl describe pod liveness-exec
At the bottom of the output, there are messages indicating that the liveness probes have failed, and the containers have been killed and recreated.

2s 2s 1 {kubelet worker0} spec.containers{liveness} Warning Unhealthy Liveness probe failed: cat: can't open '/tmp/healthy': No such file or directory
Wait another 30 seconds, and verify that the container has been restarted:
kubectl get pod liveness-exec
The output shows that RESTARTS has been incremented:
NAME READY STATUS RESTARTS AGE
liveness-exec 1/1 Running 1 1m

Answer: A

NEW QUESTION # 77
You are building a Kubernetes application tnat requires persistent storage for its dat a. The application needs to be able to access the data even if the pod is restarted or deleted. You have a PersistentVolumeClaim (PVC) defined for this purpose.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a PersistentVolume (PV):
- Define a PV with a suitable storage class, access modes (ReadWriteOnce), and a capacity that meets your application's storage requirements.
- Example:

2. Create a PersistentVolumeClaim (PVC): - Define a PVC with the desired storage class and access modes. - Specify the desired storage capacity. - Example:

3. Create a Deployment With the PVC: - In the Deployment YAML, define a volume mount that uses the PVC you created_ - Specify the volume mount path within the container. - Example:

4. Create the Deployment: - Apply the Deployment YAML using 'kubectl apply -f my-app-deployment.yamr 5. Verify the Deployment - Check the status of the Deployment using 'kubectl get deployments my-app' - Verify that the Pod is running and using the PersistentVolumeClaim. - You can also check the pod's logs for confirmation that the data is stored in the mounted volume.

NEW QUESTION # 78
You are building a microservice that requires a specific configuration file to be mounted into the container This configuration file should be updated witnout restarting tne microservice container. How can you achieve this using Kubernetes?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. use ConfigMaps:
- Create a 'ConfigMap' to store the configuration file.
- Create a YAML file (e.g., 'config.yamIS) with your configuration content:

2. Mount the ConfigMap: - In your 'Deployment definition, mount the 'configMap' into the container using a volume mount

3. Update the Configuration: - IJpdate the 'ConfigMap' directly using ' kubectl patch configmap my-microservice-config -type-merge -p '{"data": {"config-json"' "updated - The changes will be reflected in the mounted volume inside the container. 4. Access the Configuration: - Your microservice code should read the configuration file from the mounted path (e.g., '/etc/config')- Note: This approach avoids restarting the container when you need to update the configuration. The 'ConfigMaps acts as a persistent volume, and changes to its content are automatically reflected in the mounted volume inside the container

NEW QUESTION # 79
Refer to Exhibit.

Context
You have been tasked with scaling an existing deployment for availability, and creating a service to expose the deployment within your infrastructure.
Task
Start with the deployment named kdsn00101-deployment which has already been deployed to the namespace kdsn00101 . Edit it to:
* Add the func=webFrontEnd key/value label to the pod template metadata to identify the pod for the service definition
* Have 4 replicas
Next, create ana deploy in namespace kdsn00l01 a service that accomplishes the following:
* Exposes the service on TCP port 8080
* is mapped to me pods defined by the specification of kdsn00l01-deployment
* Is of type NodePort
* Has a name of cherry

Answer:

Explanation:
Solution:

NEW QUESTION # 80
