最新的 Kubernetes Administrator CKA 免費考試真題 (Q82-Q87):

問題 #82
For this item, you will have to ssh and complete all tasks on these
nodes. Ensure that you return to the base node (hostname: ) 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.

答案：

解題說明：
See the solution below.
Explanation
solution
You 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 apt has been configured so that you can install the required tools.


問題 #83
A Deployment named 'my-app-deployment' is experiencing frequent crashes. You suspect that a specific container within the Deployment is causing the crashes. How would you use Kubernetes tools and techniques to isolate and debug the problematic container?

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Examine Pod Logs:
- Use "kubectl logs ' (where is the name of a crashing pod) to examine the logs from all containers within the pod. Look for error messages, unusual patterns, or indications of failing processes.
- Analyze the log messages carefully to identify which container is likely causing the crashes.
2. Investigate Pod Events:
- Use "kubectl describe pod ' to view the pod's events.
- Look for events that might indicate a specific container is crashing or encountering issues during startup. Events will include timestamps and reasons for the events.
3. Check Container Resource Limits:
- Use 'kubectl describe pod to check the resource requests and limits defined for each container within the pod.
- If the limits are too low, the containers might be being throttled or running out of resources, leading to crashes.
4. Use a Debugger:
- If you have access to the application code and a debugger (like a remote debugger in your development environment), you can attach to the problematic container to get more detailed information about its state and execution.
- Use the 'kubectl exec' command to access a container's shell, and then run the debugger.
5. Consider Health Checks:
- Ensure that the containers have proper health checks defined (e.g., liveness probes or readiness probes).
- Health checks can help Kubernetes identify failing containers and restart them or remove them from service.
6. Isolate the Container:
- If you suspect that the container itself is faulty, try isolating it by temporarily disabling the problematic container from the pod. You can do this by either:
- Removing the container from the Pod definition: Temporarily modify the Deployment to remove the problematic container.
- Stopping the container: Use 'kubectl exec' to access the pod's shell, and then stop the container.
7. Monitor and Repeat:
- After isolating the container, monitor the Deployment to see if the crashes stop.
- If the crashes are resolved, the isolated container was likely the cause. You can then focus on troubleshooting the container itself.


問題 #84

  • A. Task Manager
  • B. System Logs
  • C. Configuration Logs
  • D. Traffic Logs

答案：A,C


問題 #85
Create a deployment as follows:
* Name:nginx-random
* Exposed via a servicenginx-random
* Ensure that the service & podare accessible via theirrespective DNS records
* The container(s) within anypod(s) running as a part of thisdeployment should use thenginxImage Next, use the utilitynslookupto lookup the DNS records of the service &pod and write the output to
/opt/KUNW00601/service.dnsand/opt/KUNW00601/pod.dnsrespectively.

問題 #86
You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000047
Task
A MariaDB Deployment in the mariadb namespace has been deleted by mistake. Your task is to restore the Deployment ensuring data persistence. Follow these steps:
Create a PersistentVolumeClaim (PVC ) named mariadb in the mariadb namespace with the following specifications:
Access mode ReadWriteOnce
Storage 250Mi
You must use the existing retained PersistentVolume (PV ).
Failure to do so will result in a reduced score.
There is only one existing PersistentVolume .
Edit the MariaDB Deployment file located at ~/mariadb-deployment.yaml to use PVC you created in the previous step.
Apply the updated Deployment file to the cluster.
Ensure the MariaDB Deployment is running and stable.

答案：

解題說明：
Task Overview
You're restoring a MariaDB deployment in the mariadb namespace with persistent data.
# Tasks:
* SSH into cka000047
* Create a PVC named mariadb:
* Namespace: mariadb
* Access mode: ReadWriteOnce
* Storage: 250Mi
* Use the existing retained PV (there's only one)
* Edit ~/mariadb-deployment.yaml to use the PVC
* Apply the deployment
* Verify MariaDB is running and stable
Step-by-Step Solution
1## SSH into the correct host
ssh cka000047
## Required - skipping = zero score
2## Inspect the existing PersistentVolume
kubectl get pv
# Identify the only existing PV, e.g.:
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS
mariadb-pv 250Mi RWO Retain Available <none> manual
Ensure the status is Available, and it is not already bound to a claim.
3## Create the PVC to bind the retained PV
Create a file mariadb-pvc.yaml:
cat <<EOF > mariadb-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mariadb
namespace: mariadb
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 250Mi
volumeName: mariadb-pv # Match the PV name exactly
EOF
Apply the PVC:
kubectl apply -f mariadb-pvc.yaml
# This binds the PVC to the retained PV.
4## Edit the MariaDB Deployment YAML
Open the file:
nano ~/mariadb-deployment.yaml
Look under the spec.template.spec.containers.volumeMounts and spec.template.spec.volumes sections and update them like so:
Add this under the container:
yaml
CopyEdit
volumeMounts:
- name: mariadb-storage
mountPath: /var/lib/mysql
And under the pod spec:
volumes:
- name: mariadb-storage
persistentVolumeClaim:
claimName: mariadb
# These lines mount the PVC at the MariaDB data directory.
5## Apply the updated Deployment
kubectl apply -f ~/mariadb-deployment.yaml
6## Verify the Deployment is running and stable
kubectl get pods -n mariadb
kubectl describe pod -n mariadb <mariadb-pod-name>
# Ensure the pod is in Running state and volume is mounted.
# Final Command Summary
ssh cka000047
kubectl get pv # Find the retained PV
# Create PVC
cat <<EOF > mariadb-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mariadb
namespace: mariadb
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 250Mi
volumeName: mariadb-pv
EOF
kubectl apply -f mariadb-pvc.yaml
# Edit Deployment
nano ~/mariadb-deployment.yaml
# Add volumeMount and volume to use the PVC as described
kubectl apply -f ~/mariadb-deployment.yaml
kubectl get pods -n mariadb
