IBM Assessment: Cloud Computing Infrastructure Architect v1 Intermediate Practice Exam: Medium Difficulty 2025

A financial services company is designing a hybrid cloud architecture that requires workloads to dynamically shift between on-premises data centers and public cloud based on compliance requirements. Which architectural pattern would BEST support this requirement while maintaining consistent management and security policies?

An organization is experiencing performance bottlenecks in their cloud application during peak hours. Monitoring shows that the database tier has adequate resources, but the application tier CPU utilization spikes to 95%. What combination of strategies would provide the MOST effective solution?

A development team needs to deploy microservices that require service discovery, load balancing, and circuit breaking capabilities. They want to avoid implementing these features in application code. Which cloud platform service approach should the architect recommend?

An enterprise is designing a multi-region cloud deployment for a customer-facing application that must achieve less than 100ms latency for users globally and maintain availability during regional outages. Which combination of architectural components is MOST appropriate?

A healthcare organization must ensure that sensitive patient data is encrypted both at rest and in transit, with encryption keys managed according to regulatory requirements that mandate key rotation every 90 days and customer control over key material. Which approach should the architect implement?

During a cloud migration assessment, an architect discovers that a legacy application uses hard-coded IP addresses and cannot be modified. The application must communicate with services in the cloud. What migration strategy should be recommended?

An organization requires that all API calls to cloud platform services be logged with detailed information about who made the call, what action was performed, and when it occurred. These logs must be retained for 7 years and be tamper-proof. Which combination of services should be implemented?

A company is migrating a three-tier application (web, application, database) to the cloud. Cost analysis shows that database licensing represents 40% of current infrastructure costs. The database workload has predictable steady-state usage with occasional reporting spikes. What optimization strategy should the architect prioritize?

An architect needs to design network security for a cloud application that processes payment card data. The application has public-facing web servers, internal application servers, and backend database servers. Which network segmentation strategy BEST aligns with security compliance requirements?

After migrating workloads to the cloud, a company notices their monthly costs are 25% higher than projected. Analysis reveals that development and test environments run 24/7, and production has over-provisioned resources with average CPU utilization of 15%. What optimization approach would deliver the FASTEST cost reduction?
