IBM Cloud Platform Application Development v2 Practice Exam 2025: Latest Questions

A developer is new to IBM Cloud and needs a quick way to organize access and billing for a small project team without giving everyone full account privileges. Which IBM Cloud construct is the BEST fit?

A team wants to deploy a containerized REST API to IBM Cloud with minimal infrastructure management and automatic scaling based on request load. Which option BEST meets these requirements?

An application must store unstructured files (images and PDFs) with high durability and access via HTTP APIs. Which IBM Cloud service is most appropriate?

A developer needs to securely provide an application running on IBM Cloud with credentials to access another IBM Cloud service, without hardcoding secrets in code. What is the RECOMMENDED approach?

A microservices application is deployed on IBM Cloud Kubernetes Service (IKS). One service cannot reach another via its Kubernetes Service name. Pods are running and ready. Which issue is the MOST likely cause?

A team needs to connect an IBM Cloud application to a managed PostgreSQL database. They want automatic backups, patching, and high availability handled by IBM. Which service should they choose?

A company must ensure that only specific applications can call an internal API, and they also want request throttling and centralized authentication. What is the BEST IBM Cloud approach?

A DevOps engineer wants consistent, repeatable provisioning of IBM Cloud resources across environments (dev/test/prod) with peer-reviewed changes and easy rollback. Which practice BEST supports this goal?

A regulated workload requires encryption of application secrets, the ability to rotate them, and audit access to those secrets. The application runs on Kubernetes. Which solution BEST satisfies these requirements on IBM Cloud?

A team is designing an event-driven architecture where multiple services must react to business events (e.g., "OrderCreated") reliably and independently. They want loose coupling and the ability to add new consumers without changing the producer. Which IBM Cloud pattern/service is the BEST fit?

A developer needs to quickly verify which IBM Cloud region and account they are currently targeting from the command line before provisioning resources. Which action is most appropriate?

A team is building a microservice that must store configuration values and credentials securely and rotate them without redeploying the application. Which IBM Cloud service is the best fit?

A developer wants to run a stateless REST API without managing servers and prefers automatic scaling based on request load. Which deployment option best matches this requirement?

A CI pipeline deploys an app to IBM Cloud. The job fails because it cannot access resources created in a specific resource group. The user can log in, but authorization errors occur when provisioning or reading services. What is the most likely cause?

A team is integrating multiple IBM Cloud services with their app and wants to avoid embedding service credentials in the source code. Which approach is recommended?

A microservice publishes events that must be processed by multiple downstream services independently. The publisher should not need to know which consumers exist. Which integration pattern and IBM Cloud service best meet this requirement?

A containerized application runs in a managed Kubernetes environment on IBM Cloud. The team wants to collect application logs centrally and query them during incident response. Which approach is most appropriate?

A team needs to deploy the same application to dev, test, and prod in IBM Cloud with consistent configuration and repeatability. Which approach best supports this goal?

After deploying a new revision of a cloud-native API, users report intermittent 5xx errors. Monitoring shows a sharp increase in latency and pod restarts. The deployment used a rolling update with default settings. Which change is most likely to reduce user impact during future rollouts?

A regulated workload must ensure that applications can access only specific IBM Cloud services and cannot exfiltrate data to the public internet. The team wants network-level controls with minimal changes to application code. Which architecture decision best addresses this?

A team is building a public-facing API on IBM Cloud and wants to centralize authentication, apply rate limiting, and generate analytics without changing the application code. Which IBM Cloud service best fits this requirement?

An application stores user-uploaded documents in IBM Cloud Object Storage. The security team requires that access to the objects be granted only via short-lived credentials and never through long-lived access keys embedded in code. What is the recommended approach?

A developer deploys a containerized microservice to IBM Cloud Kubernetes Service (IKS). The pod starts but then repeatedly restarts after failing health checks. Which Kubernetes configuration is most likely causing restarts due to an overly strict startup period?

A team uses IBM Cloud Continuous Delivery with Tekton pipelines. They want to prevent a production deployment unless automated tests pass and a manual approval is recorded. What is the best way to implement this control?

A financial services application on IBM Cloud must ensure that database credentials used by multiple microservices are rotated regularly without rebuilding container images. Which approach best meets this requirement?
