Which statement best describes the primary benefit of a multi-tenant cloud service model?

An application team wants to reduce risk when making changes by deploying the new version alongside the old one and gradually shifting traffic to validate behavior. Which deployment strategy is this?

A security engineer needs to ensure an application running on IBM Cloud can access a third-party API key without embedding the secret in code or container images. Which approach is the best practice?

A team is designing a microservices application. They want to decouple services and handle traffic bursts by buffering requests so downstream services can process work asynchronously. Which architectural component best addresses this?

A cloud administrator notices repeated failed login attempts against a public endpoint. They want automated detection and alerting based on platform logs, with minimal custom code. What is the most appropriate approach?

A product owner wants a globally distributed web application to provide low-latency responses to users in multiple regions. Static assets are large and change infrequently. Which design choice best improves performance while reducing load on the origin?

A compliance requirement states that only specific IBM Cloud services should be allowed to communicate with a backend database, and traffic must remain on the provider network rather than the public internet. Which approach best meets this requirement?

After migrating an application to IBM Cloud, users report intermittent timeouts. Metrics show the application pods frequently restart, and logs show out-of-memory (OOM) kills. What is the most likely root cause and best immediate remediation?

A company is designing a disaster recovery strategy for a mission-critical workload. They require low recovery point objective (RPO) and low recovery time objective (RTO) across regions. Which design best aligns with these requirements?

A development team wants to deploy a stateless web application on IBM Cloud without managing servers. The application should automatically scale based on demand. Which option best fits this requirement?

A team is evaluating cloud models. They want to use shared provider-managed infrastructure while retaining control over their application configuration and data. Which cloud service model does this describe?

An application is being migrated to IBM Cloud. The security team requires that data exchanged between microservices is encrypted in transit. Which approach best meets this requirement?

A site reliability engineer wants to reduce the impact of a single availability zone failure for a customer-facing app running on IBM Cloud. Which design choice best improves resiliency?

A team uses IBM Cloud Object Storage to store user uploads. They need to ensure that accidental deletion can be recovered for a limited period. Which feature best addresses this requirement?

A company must enforce that developers can deploy resources only in a specific IBM Cloud resource group and cannot create IAM policies. What is the BEST way to implement this?

A microservices application experiences intermittent failures when calling an external payment API. The team wants to prevent cascading failures and reduce pressure on the failing dependency. Which pattern should be implemented?

An operations team wants to be alerted when application latency exceeds a threshold and also wants to troubleshoot by correlating metrics with logs. Which approach best meets this need on IBM Cloud?

A regulated workload requires that encryption keys are controlled by the customer and are not accessible to the cloud provider. Which IBM Cloud capability is most appropriate?

A company is designing a multi-region architecture for disaster recovery. The RPO requirement is close to zero and the RTO must be very low. Which design best meets these requirements?

A developer wants to run a containerized API on IBM Cloud without managing servers, and wants automatic scaling based on incoming HTTP requests. Which IBM Cloud service best fits this requirement?

An application is deployed across two availability zones for high availability. The database is in a single zone and becomes a single point of failure. What is the best architectural improvement to reduce this risk?

Which statement best describes the main benefit of measured service in cloud computing?

A security team wants to ensure credentials for external services (API keys, passwords) are not stored in source code or container images. Which approach is the best practice on IBM Cloud?
