Quiz

1/10
You are tasked with deploying a highly available application in OpenShift. Create a Deployment using YAML to deploy the nginx container with three replicas, ensuring that it runs successfully. Verify that the Deployment is active, all replicas are running, and the application can serve requests properly. Provide a complete walkthrough of the process, including necessary commands to check deployment status.
Select the answer
1 correct answer
Deployments provide a scalable and declarative way to manage applications. YAML manifests ensure the configuration is consistent, while NodePort services expose the application for testing. Verifying replicas ensures that the application is running as expected and resilient.

Quiz

2/10
Your team requires an application to load specific configuration data dynamically during runtime. Create a ConfigMap to hold key-value pairs for application settings, and update an existing Deployment to use this ConfigMap. Provide a complete YAML definition for both the ConfigMap and the updated Deployment, and demonstrate how to validate that the configuration is applied correctly.
Select the answer
1 correct answer
ConfigMaps decouple configuration data from the application code, enabling environment-specific settings without altering the deployment logic. Using environment variables from ConfigMaps ensures flexibility and reduces maintenance complexity.

Quiz

3/10
Your cluster requires an application to be exposed to external users. Use the OpenShift CLI to expose an application running on the nginx Deployment as a service, making it accessible via NodePort. Provide step-by-step instructions, including testing the accessibility of the service from the host machine.
Select the answer
1 correct answer
NodePort services allow external access to applications for testing or specific use cases. This ensures that developers and testers can interact with the application from outside the cluster without requiring advanced ingress configurations.

Quiz

4/10
Your organization needs a shared storage solution for an application running on OpenShift. Configure a PersistentVolume (PV) and a PersistentVolumeClaim (PVC), and update an existing Deployment to use this storage. Include a demonstration of how to validate that the storage is mounted correctly in the application pods.
Select the answer
1 correct answer
Persistent volumes and claims abstract storage allocation in Kubernetes. By binding PVs to PVCs, applications can use persistent storage seamlessly across deployments, ensuring data persistence beyond pod lifecycles.

Quiz

5/10
Configure a Role-based Access Control (RBAC) setup to allow a user named dev-user to list all pods in the test-project namespace. Provide YAML definitions for the Role and RoleBinding, and demonstrate how to verify the permissions.
Select the answer
1 correct answer
RBAC provides fine-grained access control, enabling administrators to assign specific permissions to users or groups. Verification ensures the intended access level is configured.

Quiz

6/10
Troubleshoot a pod stuck in the CrashLoopBackOff state. Investigate and resolve an issue where the application fails due to a missing environment variable. Provide commands to identify the problem and fix it.
Select the answer
1 correct answer
CrashLoopBackOff indicates repeated failures. Investigating logs and descriptions often reveals misconfigurations. Updating the Deployment resolves the issue without redeploying the entire application.

Quiz

7/10
Use the OpenShift CLI to back up the resource configuration of the test-project namespace into a single file. Provide commands to export and restore these resources.
Select the answer
1 correct answer
Exporting resource configurations allows administrators to create backups for disaster recovery. Applying the backup ensures that the namespace state can be restored quickly.

Quiz

8/10
Deploy an application using a Helm chart. Use the nginx chart from the stable repository and provide instructions to customize the deployment.
Select the answer
1 correct answer
Helm simplifies application deployment by packaging pre-configured resources. Customizing values during installation ensures the deployment meets specific requirements.

Quiz

9/10
Set up OpenShift monitoring to send email alerts when CPU usage exceeds 80% for any node. Include steps to configure an alert in Prometheus.
Select the answer
1 correct answer
Setting up alerts ensures proactive monitoring. Prometheus rules allow administrators to customize alerts for specific metrics.

Quiz

10/10
Inspect all events in the cluster and filter for warnings related to pods. Provide commands to gather and analyze the data.
Select the answer
1 correct answer
Cluster events provide a timeline of activities. Filtering warnings helps identify potential issues requiring attention.
