최신 Kubernetes Application Developer CKAD 무료샘플문제 (Q183-Q188):
질문 # 183
You are tasked witn building a container image for a Node.js application that needs to interact with a MongoDB database. Describe now you would configure your Dockerfile to include MongoDB and how you would set up your Node.js application to connect to the database within the container.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Utilize a Multi-Stage Dockerfile: Employ a multi-stage Dockerfile to separate the build and runtime environments, optimizing the final image size.
2. Install MongoDB in the Base Image: - Use a suitable MongoDB base image, such as 'mongo:latest', in the runtime stage. 3. Install Node.js Dependencies: - IJse a Nodejs base image, such as 'node:16-alpine', in the build stage. - Install Node.js dependencies using 'yarn install'. 4. Connect to MongoDB from the Node.js Application: - In your Node.js application, use a MongoDB driver (e.g., 'mongodb') to establish a connection to the MongoDB instance.
5. Build and Run the Container: - Build the image using 'docker build . -t my-node-mongo-apps - Run the container using 'docker run -it -p 2701727017 my-node-mongo-app' - The '-p 27017:27017' mapping exposes the MongoDB port to your host machine, allowing you to connect to the database from your local machine. 6. Access MongoDB. - You can use a MongoDB client tool (e.g., Mongo Shell, Robo 3T) or other applications to connect to the MongoDB instance running inside the container.,
질문 # 184
You have a Kubernetes cluster running a critical application With multiple pods. Recently, the application has started experiencing intermittent performance issues, with some pods exhibiting high CPU utilization and others remaining idle. You suspect a network issue might be the culprit. Describe the steps you would take to investigate this issue and determine the source of the network problem.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Gather Logs and Metrics:
- Kubernetes Events: use 'kubectl get events' to see if any events related to pods, services, or network issues are being logged.
- Container Logs: Inspect the logs of the affected pods to see if any network-related errors are reported.
- Metrics: Utilize tools like Prometheus or Grafana to monitor metrics like:
- CPU Utilization: Identify pods With high CPIJ usage.
- Network 1/0: Monitor network traffic patterns and look for anomalies.
- Latency: Check for network delays pods and services-
- Network Monitoring Tools: TOOIS like Wireshark or tcpdump can be used to capture and analyze network traffic for deeper insignts.
2. Examine Network Connectivity:
- Ping Test Run 'pings commands to check the connectivity between pods, nodes, and external services.
- Connectivity Tests: Use 'kubectl exec' to access a pod and #fform 'curl' commands to verify connectivity to services and other pods.
3. Inspect Network Configuration:
- Network Policies: Review any network policies applied to the pods, namespaces, or the cluster.
- Service Definitions: Check tne 'service' definitions to ensure tney are correctly configured and routing traffic as intended.
- Network Plugins: If using a network Plugin like Calico or Flannel, review its configuration and logs for any issues.
- Network Namespaces: Verity if the pods are using the correct network namespaces.
4. Analyze Network Traffic:
- Traffic Flow IJse tools like 'kubectl describe service' to analyze how traffic flows through the services and pods.
- Network Tracing: Utilize tracing tools to map tne flow of requests through the network and identify potential bottlenecks.
- Network Bandwidth: Check if the network bandwidth is sufficient to handle the traffic load-
5. Isolate and Resolve the Issue:
- Restart Pods: Try restarting the affected pods to see if it resolves the issue.
- Update Network Configurations: Adjust network policies, service definitions, or plugin settings if required.
- Network Troubleshooting: Utilize the collected information and network analysis tools to pinpoint the root cause.
6. Implement a Solution:
- Network Optimization: Adjust network settings or configurations to improve performance.
- Scaling: Increase the number of pods or modify deployment strategies if necessary.
- Network Monitoring: Implement continuous monitoring and alerting for potential network issues.,

질문 # 187
You're tasked with deploying a containerized application that handles sensitive customer datm The security policy mandates that only containers With specific security profiles can access the dat a. How would you implement Pod Security Standards (PSS) in your Kubernetes cluster to enforce this requirement?
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Pod Security Policies:
- Create a Pod Security Policy (PSP) resource using a YAML file.
- Define the allowed security profiles based on your security requirements.
- You can restrict things like:
- Container privileges (root or non-root)
- Allowed capabilities (e.g., 'SYS_ADMINS)
- Security context constraints (e.g., read-only root filesystem)
- Access to host resources (e.g., devices, networking)
2. Apply the Pod Security Policy: - Use 'kubectl apply -f sensitive-data-psp.yamr to apply the PSP to your cluster. 3. Modify Your Deployment (or other workload) to IJse the PSP: - Update the Deployment (or other workload) YAML file to include a 'securitycontext' field that references the PSP you created. - Ensure that the container image and configuration adhere to the constraints defined in the PSP.
4. Verify Deployment: - Use ' kubectl get pods -l app=sensitive-data-app' to ensure your pods are running. - The poos should now adhere to the specified security constraints defined by the PSP 5. Enforcement: - Kubernetes will prevent pods from running if they violate the constraints defined in the PSP - This provides a layer of security enforcement for sensitive applications. Note: PSPs are deprecated in Kubernetes 1.25 and are replaced by Pod Security Admission. For newer Kubernetes versions, you would use Pod Security Admission to enforce these security constraints. ]
