Oracle Cloud Infrastructure 2025 Developer Professional Practice Exam: Test Your Knowledge 2025

Your team is developing a microservices-based application on OCI and needs to implement service-to-service communication with automatic retries, circuit breakers, and traffic management. Which OCI service should you use to implement this functionality without modifying application code?

You are deploying a containerized application to OCI Container Engine for Kubernetes (OKE). The application requires persistent storage that can be dynamically provisioned and shared across multiple pods simultaneously with read-write access. Which storage option should you configure?

A developer is creating an OCI Function that needs to access secrets stored in OCI Vault. What is the recommended approach to authenticate the function to retrieve these secrets?

Your application uses OCI Streaming service and you need to ensure that messages are processed in order within a partition, but you want to maximize parallel processing across partitions. Which consumer implementation pattern should you use?

You need to monitor the performance of your OCI Functions and set up alerts when function execution time exceeds a specific threshold. Which OCI service should you use to accomplish this?

A development team is implementing a distributed tracing solution for their microservices architecture running on OKE. They want to correlate requests across multiple services and identify performance bottlenecks. Which OCI service provides distributed tracing capabilities?

You are designing a serverless application on OCI that needs to process uploaded images. Users upload images to Object Storage, which should trigger automatic processing. What is the most appropriate architecture to implement this?

Your containerized application running on OKE needs to scale based on custom metrics such as queue depth from OCI Streaming. Which Kubernetes component should you configure to enable this custom metric-based scaling?

You need to implement API rate limiting and request throttling for your REST APIs deployed on OCI. Which service provides these capabilities with minimal operational overhead?

Your application uses OCI Queue service for asynchronous message processing. Messages occasionally fail processing due to transient errors. What is the best practice to handle these failed messages without losing data?

A microservices application on OKE is experiencing intermittent connection failures between services. You need to identify which service is causing the failures and analyze the communication patterns. Which combination of OCI services provides the most comprehensive troubleshooting capability?

You are implementing a blue-green deployment strategy for an application on OKE. Which approach allows you to instantly switch traffic between the blue and green environments with the ability to quickly rollback?

Your OCI Function needs to call another OCI Function synchronously and wait for the response. The second function typically takes 3 minutes to complete. What should you consider in this design?

You need to implement a fan-out messaging pattern where a single message should be processed by multiple independent consumer applications. Which OCI service is most appropriate for this requirement?

Your application running on OKE needs to securely access OCI services like Object Storage and Autonomous Database. What is the recommended authentication approach that avoids managing credentials in the cluster?

You are designing an event-driven architecture where multiple services need to react to the same events from OCI Streaming. Each service should process events independently and maintain its own processing position. How should you configure the consumers?

Your OKE cluster is experiencing pod scheduling failures with the error 'Insufficient cpu'. You have verified that worker nodes have available CPU resources. What is the most likely cause and solution?

You need to implement request/response correlation across multiple microservices for troubleshooting purposes. What is the best practice approach?

Your application uses OCI API Gateway with multiple backend services. You need to transform request and response payloads before they reach the backend and before returning to clients. Which API Gateway feature should you use?

You need to ensure that messages in OCI Streaming are retained for compliance purposes for 7 days, even after they have been consumed. How should you configure this?
