A team is explaining cloud computing to new hires. Which statement best describes elasticity in cloud computing?

A cloud architect is asked to recommend a best practice for segregating resources for multiple environments (dev, test, prod) while keeping billing and access control cleanly separated. What is the best approach?

A company is troubleshooting sporadic login failures for a web application deployed across multiple instances. Logs show that some requests are routed to instances that do not recognize the user session. Which infrastructure-level change most directly addresses this issue without changing application code?

A retailer expects unpredictable traffic spikes and wants to minimize operational overhead while ensuring the application can scale quickly. The application is stateless and can be packaged as containers. Which architecture is most appropriate?

A company must integrate an on-premises ERP system with a cloud-based order processing service. The integration must be reliable, tolerate intermittent network issues, and decouple the two systems. What is the best design choice?

An application stores images and must deliver them globally with low latency. The images are rarely updated, but when they change, users should see updates within minutes. Which approach best meets this requirement?

A development team wants to reduce deployment risk by shifting traffic gradually to a new version of a microservice and rolling back quickly if error rates rise. Which release strategy best fits?

A regulated workload requires that encryption keys are controlled by the customer and rotated according to policy. Auditors also require separation of duties so that cloud administrators cannot export keys. Which solution best meets these requirements?

A company is migrating a monolithic application to the cloud. The database is highly transactional and must remain consistent, but the application tier can be modernized later. They want minimal changes now and a migration that reduces downtime. Which approach is most appropriate?

A multi-tier cloud application experiences occasional failures when calling an external payment API. The failures correlate with short network interruptions. The architect wants to improve resiliency and avoid amplifying load on the payment provider during partial outages. Which pattern is the best fit?

A project team is adopting cloud computing and wants a simple way to explain a key difference between virtualization and cloud computing to stakeholders. Which statement is MOST accurate?

A company is defining service-level objectives for a new cloud-based application. Which metric BEST aligns with the principle of "measured service" in cloud computing?

An application experiences unpredictable traffic spikes. The team wants to avoid overprovisioning while still meeting performance targets. Which cloud capability BEST addresses this requirement?

A solution architect is designing a cloud application and wants to reduce the blast radius of a component failure. Which design approach BEST supports this goal?

A company must integrate an on-premises order management system with a cloud-hosted inventory service. The systems use different message formats and require guaranteed delivery. Which integration approach is MOST appropriate?

A team is migrating a multi-tier application to the cloud. They want to minimize downtime during cutover and validate the new environment under real traffic before switching fully. Which migration strategy BEST fits?

A cloud application uses stateless web servers and a managed database. During a failure, the web tier recovered quickly but users still experienced errors because the database became a bottleneck. Which architectural change MOST directly improves resilience for the database layer?

A security review finds that an application running in the cloud uses long-lived credentials embedded in code to access storage services. What is the BEST practice remediation?

A financial services company requires that all customer data remains within a specific geographic boundary, but it also needs high availability. Which design BEST meets both requirements?

After migrating an application, users report intermittent failures. Logs show that requests sometimes hit new cloud instances that do not have the latest configuration values. The application instances are frequently replaced by auto-scaling. What is the MOST likely root cause and best fix?

A team is comparing cloud service models for a new customer-facing web app. They want the provider to manage the OS, runtime, and patching, while the team focuses on deploying code and scaling. Which cloud service model best fits this requirement?

A cloud architect is asked to design for high availability across data centers. Which approach most directly improves availability if a full site failure occurs?

A developer reports that a stateless API running in containers intermittently fails to connect to an internal database. The database is only reachable on a private network. What is the MOST likely architectural cause?

A retailer wants to modernize an application by decoupling order intake from downstream processing. They need asynchronous communication and the ability to absorb traffic spikes without dropping requests. Which design is the BEST fit?

A company is migrating an existing application to the cloud. They want to move quickly with minimal code change but still reduce the risk of configuration drift between environments. Which approach best supports this goal?

An organization wants to enforce that only approved images are deployed to its container platform and that each deployment is traceable to a specific build. Which practice best addresses this requirement?

A regulated workload requires encryption in transit and at rest, plus strict separation between application tiers. The architect proposes placing the database in a private subnet with no public IPs and allowing access only from the application subnet. Which additional control MOST directly enforces this separation at the network level?

A global application must serve users with low latency while maintaining a single authoritative source of truth for transactional data. The architect considers replicating the primary database to multiple regions. Which risk must be MOST carefully managed when using multi-region replication for transactions?
