Red Hat Certified Specialist in OpenShift Application Development (EX288) Mock Test

Overview

The Red Hat Certified Specialist in OpenShift Application Development exam (EX288) is a rigorous, performance-based test designed to validate the skills and knowledge of developers working with Red Hat OpenShift Container Platform. This certification is ideal for developers who need to demonstrate their proficiency in creating, deploying, and managing containerized applications on an OpenShift cluster. Earning this credential showcases your ability to leverage OpenShift's powerful features for agile application development and deployment, making you a valuable asset in organizations adopting cloud-native strategies. The exam is practical, requiring candidates to perform real-world tasks within an OpenShift environment, ensuring that certified professionals possess hands-on expertise.

Syllabus Chapters

To succeed in the EX288 exam, a deep understanding of the following key areas is essential:

• Manage OpenShift Projects: Create and manage projects, understand resource quotas, and control access permissions within OpenShift.
• Create and Manage Applications: Deploy applications using various methods like oc new-app, define application resources, and manage application lifecycles.
• Build Applications with Source-to-Image (S2I): Utilize S2I for building container images directly from source code, customize S2I builds, and integrate with Git repositories.
• Configure Application Networking: Expose applications using routes, manage internal and external network access, and understand OpenShift networking concepts.
• Troubleshoot Applications: Diagnose and resolve common application deployment and runtime issues using OpenShift tools and logs.
• Implement Continuous Integration/Continuous Deployment (CI/CD): Use OpenShift Pipelines (Tekton) or other CI/CD tools to automate application builds, tests, and deployments.
• Manage Application Storage: Provision and consume persistent storage for stateful applications using Persistent Volumes (PVs) and Persistent Volume Claims (PVCs).
• Utilize Service Mesh Features: Implement and configure Service Mesh (e.g., Istio/Kiali) for traffic management, observability, and security of microservices.
• Work with Serverless Applications: Understand and deploy serverless functions using Knative on OpenShift.

Test Rules

1. The exam is a performance-based test, meaning you will perform tasks on a live OpenShift environment.
2. You will have 3 hours (180 minutes) to complete the exam.
3. No outside materials, notes, or internet access (other than specified documentation within the exam environment) are allowed.
4. All tasks must be completed using the provided OpenShift cluster and tools.
5. Read each question carefully and ensure all requirements are met.
6. Save your work frequently, as progress might not be automatically saved.

Scoring

The EX288 exam is scored based on the successful completion of specific tasks. Each task has a defined number of points. To pass the exam, a candidate must achieve a score of 70% or higher. There is no partial credit for partially completed tasks; tasks are typically graded as all-or-nothing. The specific passing score ensures that certified professionals have a robust understanding and practical ability in OpenShift application development. Results are typically provided within a few business days after the exam.

Preparation Tips

• Hands-on Practice: The most crucial preparation is extensive hands-on experience with OpenShift. Set up your own local OpenShift cluster (e.g., Minishift, CodeReady Containers) or use a cloud-based sandbox.
• Review Red Hat Documentation: The official Red Hat documentation for OpenShift Container Platform is an invaluable resource. Familiarize yourself with key concepts and oc commands.
• Understand Core Concepts: Ensure you have a solid grasp of Kubernetes concepts (Pods, Deployments, Services, Routes, ConfigMaps, Secrets, Persistent Volumes) as they underpin OpenShift.
• Practice with Example Applications: Work through deploying and managing various types of applications (e.g., Java, Node.js, Python) using different build strategies (S2I, Dockerfiles).
• Focus on Troubleshooting: Develop strong troubleshooting skills. Practice identifying and resolving common issues related to deployments, networking, and storage.
• Mock Tests: Utilize mock tests to simulate the exam environment and identify areas where you need further practice. Our mock test provides a realistic simulation.
• Time Management: During practice, pay attention to the time it takes to complete tasks. The exam has a strict time limit.
