IBM Assessment: Cloud Solutions v1 Practice Exam 2025: Latest Questions

A startup is designing a new customer-facing API expected to have unpredictable traffic spikes. The team wants to minimize operational overhead while ensuring the API scales automatically. Which approach best fits this requirement?

An application uses multiple microservices and needs a way to externalize configuration (such as feature flags and environment-specific settings) without rebuilding images for each environment. What is the recommended cloud-native approach?

A company is migrating a web application to the cloud and wants to reduce the risk of downtime. They plan to keep the on-premises version running while gradually shifting traffic to the cloud deployment. Which migration strategy is this?

A security team requires that all data stored in cloud object storage be encrypted and that access be limited to only approved identities. Which combination best meets this requirement?

A retail company needs a resilient architecture for a critical ordering service. They want to avoid single points of failure and ensure the service remains available even if a zone failure occurs. Which design best achieves this?

After migrating an application to the cloud, users report intermittent slow responses during peak hours. Metrics show CPU is low, but database connections frequently hit a maximum limit. What is the most likely root cause?

A company has on-premises systems that publish order events and multiple cloud services that must react to those events asynchronously. They want loose coupling and the ability to replay events for new consumers. Which integration approach is most appropriate?

An organization must demonstrate that only authorized administrators can modify cloud resources and that all changes are traceable for audits. Which control set best satisfies this requirement?

A financial services company is deploying workloads to a multi-tenant cloud environment. They require strong separation between environments (dev, test, prod) and need to minimize the blast radius of misconfigurations while still allowing centralized governance. What is the best architectural approach?

A company is modernizing a monolithic application into microservices. One service must make a change that triggers updates in two other services, but the organization wants to avoid distributed transactions and still maintain eventual consistency. Which pattern best addresses this?

A development team is building a new cloud-native application and wants independent scaling and deployment of components. Which architecture best supports this goal?

A company needs to connect a cloud application to an on-premises system using asynchronous communication to handle bursts of traffic. Which integration approach is most appropriate?

A security team wants to ensure that cloud resources can be audited to determine who changed configurations and when. What capability best addresses this requirement?

A retail application experiences intermittent failures when calling an external payment API. The team wants to prevent cascading failures and allow the app to recover quickly when the API becomes healthy again. Which resilience pattern should be implemented?

An organization is migrating a legacy application to the cloud. The application cannot be modified in the short term, but the company wants to reduce risk and move quickly. Which migration approach is most appropriate?

A team is deploying an application to multiple environments (dev/test/prod). They need consistent, repeatable infrastructure provisioning with peer review and the ability to roll back changes. What is the best practice approach?

A company must integrate several internal services and wants a single entry point for clients, consistent authentication, rate limiting, and request routing to the correct backend. Which component best meets these needs?

A regulated company needs to enforce least privilege for cloud administrators by granting only the permissions needed for specific tasks (e.g., read-only auditors vs. network admins). What is the best approach?

A cloud application uses short-lived containers that frequently restart. Troubleshooting is difficult because logs are scattered across instances and lost when containers terminate. What is the most effective solution?

A company is designing for high availability across two regions. They need the ability to continue operating if an entire region is unavailable, but also want to minimize data inconsistency. Which design best balances these requirements?

A product team is building a customer-facing API on a cloud platform. Traffic is unpredictable and they want to avoid capacity planning while still supporting horizontal scaling. Which design choice best aligns with cloud-native best practices?

A company is migrating a 3-tier application to the cloud. The database must remain in the on-premises data center for the next 6 months due to a vendor contract. Users in the cloud-hosted web tier are experiencing high latency when the app queries the database. Which approach most directly addresses the issue while the database stays on-premises?

An enterprise needs to integrate an on-premises order system with multiple cloud services. Messages must be delivered at least once, and the integration should buffer spikes in traffic without losing messages. Which integration pattern is most appropriate?

A regulated workload must ensure that object storage data is encrypted and that encryption keys are not managed by the cloud provider. Security also requires the ability to rotate and revoke keys on demand. Which approach best meets these requirements?

A team deploys a microservices application and observes intermittent timeouts between services during peak load. CPU and memory are within normal ranges, but downstream services sometimes respond slowly. The team wants to improve resiliency without changing business logic. Which solution is most appropriate?
