   A company has a critical application that requires high availability and can tolerate brief periods of data inconsistency. The application has several components that need to react to changes in other components. The team is experienced with asynchronous programming. They are considering an event-driven architecture. What is a key trade-off they must accept?

   • AIncreased complexity in debugging and monitoring due to asynchronous flows
   • BTighter coupling between components because they must share a database
   • CSimpler deployment because all components are deployed as a single unit
   • DReduced scalability because the event broker becomes a bottleneck

   A company is building a new application that will have several services. They want to ensure that if one service fails, it does not cause a cascade of failures across the application. They are considering both microservices and event-driven architecture. Which combination of patterns best addresses this concern?

   • AService-oriented architecture with an ESB and synchronous calls
   • BMonolithic architecture with a shared database
   • CMicroservices with synchronous REST calls and a circuit breaker
   • DEvent-driven architecture with a message broker and asynchronous communication

   A company has a monolithic application that is becoming difficult to scale because the entire application must be replicated to handle increased load on one component. The team is considering moving to microservices. However, they are concerned about the operational complexity of managing many services. They want to reduce the risk of the migration. Which approach best addresses their concerns?

   • AStart by extracting the highest-load component into a separate service, while keeping the rest as a monolith
   • BUse a service-oriented architecture with an ESB
   • CKeep the monolith and add more servers to handle the load
   • DMigrate all components to microservices at once
