Linux Foundation Certified Kubernetes Application Developer Exam 認定 CKAD 試験問題 (Q80-Q85):

質問 # 80
Context

Context
Developers occasionally need to submit pods that run periodically.
Task
Follow the steps below to create a pod that will start at a predetermined time and]which runs to completion only once each time it is started:
* Create a YAML formatted Kubernetes manifest /opt/KDPD00301/periodic.yaml that runs the following shell command: date in a single busybox container. The command should run every minute and must complete within 22 seconds or be terminated oy Kubernetes. The Cronjob namp and container name should both be hello
* Create the resource in the above manifest and verify that the job executes successfully at least once

質問 # 81
You are deploying a sensitive application that requires strong security measures. You need to implement a solution to prevent unauthorized access to the container's runtime environment. How would you use Seccomp profiles to enforce security policies at the container level?

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Seccomp Profile:
- Create a new YAML file (e.g., 'seccomp-profile.yaml') to define your Seccomp profile.
- Specify the name of the Seccomp profile and the namespace where it will be applied.
- Define the allowed syscalls for the container. You can use the 'seccomp' tool or the
'k8s.io/kubernetes/pkg/security/apparmor/seccomp' package to generate the profile.

2. Apply the Seccomp Profile: - Apply the Seccomp profile to your cluster using the following command: bash kubectl apply -f seccomp-profile.yaml 3. Deploy Applications with Seccomp Profile: - Update your Deployment YAML file to include the Seccomp profile:

4. Verify the Seccomp Profile: - Check the status of the pods with 'kubectl describe pod - Look for the "Security Context" section and verify that the Seccomp profile is correctly applied. 5. Test the Restrictions: - Try to access system resources or make syscalls that are not allowed by your Seccomp profile. - Verify that the profile is effectively restricting the container's access to system resources.

質問 # 82
Exhibit:

Task
You are required to create a pod that requests a certain amount of CPU and memory, so it gets scheduled to-a node that has those resources available.
* Create a pod named nginx-resources in the pod-resources namespace that requests a minimum of 200m CPU and 1Gi memory for its container
* The pod should use the nginx image
* The pod-resources namespace has already been created

A. Solution:
B. Solution:

正解：A

質問 # 83
You have a stateful set named 'mysql-statefulset' that runs a MySQL database. The database data is stored in a PersistentV01umeClaim (PVC) named 'mysql-pvc' _ You want to ensure that the PVC is always mounted to the same pod, even after a pod restart or replacement. Additionally, you want to configure the PVC to use a specific storage class tor data persistence.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Storage Class:
- Create a storage class YAML file with the desired storage class name and parameters, such as 'accessModes', 'reclaimPolicy' , and 'provisioner'.

- Apply the YAML file using 'kubectl apply -f mysql-storage.yaml' 2. Create a PersistentVolumeClaim: - Create a PVC YAML file With the storage class defined, and specify the storage size and access modes for the PVC.

- Apply the YAML file using 'kubectl apply -f mysql-pvc.yamr 3. Define the StatefulSet: - Update the 'mysql-statefulset' YAML file: - Set the 'spec-template-spec-containers-volumeMounts' to mount the 'mysql-pvc' volume to the container- - Define a 'spec-volumeClaimTemplates' section to define the volume claim associated with the StatefulSet.

- Apply the YAML file using 'kubectl apply -f mysql-statefulset.yamr 4. Verify the StatefulSet: - Check the status of the StatefulSet using 'kubectl get sts mysql-statefulset' - Use ' kubectl describe pod mysql-o' to verify that the 'mysql-pvc' is mounted to the pod and the storage class is being used 5. Test Pod Replacement: - Delete a pod within the StatefulSet (e.g., 'kubectl delete pod mysql-O'). - Observe that a new pod is automatically created witn the same name Cmysql-ff) and the 'mysql-pvc' is mounted to it. 6. Monitor the Database: - Connect to the MySQL database using the 'kubectl exec' command and verify that the data is preserved even after a pod restan or replacement. These steps ensure that your mysql-statefulset utilizes a specific storage class for data persistence and the PVC is always mounted to the same pod, providing consistent data access. ,

Refer to Exhibit.

Set Configuration Context:
[student@node-1] $ | kubectl
Config use-context k8s
Context
A user has reported an aopticauon is unteachable due to a failing livenessProbe .
Task
Perform the following tasks:
* Find the broken pod and store its name and namespace to /opt/KDOB00401/broken.txt in the format:
<namespace>/<pod>

The output file has already been created
* Store the associated error events to a file /opt/KDOB00401/error.txt, The output file has already been created. You will need to use the -o wide output specifier with your command
* Fix the issue.

正解：

解説：
To find the broken pod and store its name and namespace to /opt/KDOB00401/broken.txt, you can use the kubectl get pods command and filter the output by the status of the pod.
kubectl get pods --field-selector=status.phase=Failed -o jsonpath='{.items[*].metadata.namespace}/{.items[*].metadata.name}' > /opt/KDOB00401/broken.txt This command will list all pods with a status of Failed and output their names and namespaces in the format <namespace>/<pod>. The output is then written to the /opt/KDOB00401/broken.txt file.
To store the associated error events to a file /opt/KDOB00401/error.txt, you can use the kubectl describe command to retrieve detailed information about the pod, and the grep command to filter the output for error events.
kubectl describe pods <pod-name> --namespace <pod-namespace> | grep -i error -B5 -A5 > /opt/KDOB00401/error.txt Replace <pod-name> and <pod-namespace> with the name and namespace of the broken pod you found in the previous step.
This command will output detailed information about the pod, including error events. The grep command filters the output for lines containing "error" and also prints 5 lines before and after the match.
To fix the issue, you need to analyze the error events and find the root cause of the issue.
It could be that the application inside the pod is not running, the container image is not available, the pod has not enough resources, or the liveness probe configuration is incorrect.
Once you have identified the cause, you can take appropriate action, such as restarting the application, updating the container image, increasing the resources, or modifying the liveness probe configuration.
After fixing the issue, you can use the kubectl get pods command to check the status of the pod and ensure
