IBM Cloud Platform Application Development v2 Intermediate Practice Exam: Medium Difficulty 2025

A development team is deploying a Node.js application to IBM Cloud Foundry. The application requires environment-specific configuration for database connections that should not be hardcoded. Which approach best follows IBM Cloud best practices for managing this configuration?

An application running on IBM Cloud needs to authenticate users and integrate with multiple IBM Cloud services. The development team wants to implement a secure authentication mechanism that follows IBM Cloud identity and access management best practices. What approach should they use?

A microservices-based application on IBM Cloud Kubernetes Service consists of multiple containers that need to communicate with each other. Some services should only be accessible within the cluster, while others need external access. How should the development team configure network access?

A company is building a cloud-native application that processes customer orders and needs to integrate IBM Cloudant for data persistence. The application experiences variable load throughout the day. What design pattern should be implemented to handle database connection management efficiently?

A development team needs to implement a CI/CD pipeline for an application deployed on IBM Cloud. The pipeline should automatically build, test, and deploy code changes to a staging environment, but require manual approval before production deployment. Which IBM Cloud service configuration would best accomplish this?

An application on IBM Cloud needs to process messages asynchronously from multiple sources and ensure message delivery even if processing services are temporarily unavailable. The solution should decouple message producers from consumers. Which IBM Cloud service and pattern would be most appropriate?

A containerized application deployed on IBM Cloud is experiencing performance issues during peak hours. The monitoring shows high CPU usage and increased response times. The team wants to implement automatic scaling based on resource utilization. What configuration approach should they implement?

A company is migrating a monolithic application to IBM Cloud and wants to adopt a microservices architecture. The application has a user authentication component that will be used by multiple microservices. What architectural pattern should be implemented for authentication?

A development team is using IBM Cloud Databases for PostgreSQL in their application. They need to ensure data durability and implement a disaster recovery strategy that meets a Recovery Point Objective (RPO) of 1 hour. What combination of IBM Cloud features should they configure?

An application deployed on IBM Cloud needs to handle sensitive customer data and comply with data protection regulations. The development team must implement proper logging while ensuring sensitive information is not exposed. What approach should they follow?
