A team needs to expose an HTTP API to external consumers and also enforce policies such as rate limiting, OAuth validation, and logging. Which IBM Cloud Pak for Integration capability is most appropriate?

A new integration must reliably deliver messages between two applications, and the receiving application can only process a limited number of messages at a time. Which messaging pattern best fits this requirement?

A solution architect is designing a multi-tenant integration platform using Cloud Pak for Integration. Different application teams require isolation of runtime resources while sharing the same OpenShift cluster. Which design approach is most appropriate?

A company is implementing event-driven integration. Multiple independent services must react to business events (for example, "OrderCreated") without the producer knowing the consumers. Which capability and pattern best matches this requirement?

An integration uses App Connect to orchestrate several downstream REST APIs. The architect must ensure that credentials for these endpoints are not stored in plain text in flow definitions and can be rotated without redeploying the entire application. What is the best approach?

A team reports that messages are accumulating on an MQ queue and the consuming application is not processing them. The MQ channel shows RUNNING. What is the most likely first item to check from an integration perspective?

A regulated organization requires that every API request be traced end-to-end across API gateway, integration flows, and messaging so that audits can correlate a business transaction to all technical hops. Which design choice best supports this requirement?

A solution must expose an API that triggers an integration flow which publishes an event. The architect wants to avoid duplicate event publication when the client retries due to transient network failures. Which approach is the most robust?

A customer wants a single place for developers to discover, test, and subscribe to APIs implemented across multiple runtimes in Cloud Pak for Integration. Which capability should the solution architect recommend?

An integration team is choosing between asynchronous event-driven integration and synchronous request/reply APIs for propagating customer profile updates to many downstream systems. The key requirement is to minimize coupling and allow new consumers to be added without changing producers. Which approach best meets the requirement?
