   A company is redesigning its customer-facing application. They want to deploy new features for different parts of the application independently. For example, the team wants to update the recommendation engine without redeploying the entire application. They also want each team to own its data and scale only the services that experience high load. Which architectural pattern best meets these requirements?

   • AService-oriented architecture with an ESB
   • BEvent-driven architecture
   • CMonolithic architecture
   • DMicroservices architecture

   A company has a microservices-based application where services communicate synchronously via REST. They are experiencing performance issues because some services are slow, and the slow responses are causing timeouts in other services. They want to improve resilience and reduce coupling. They are considering moving to event-driven communication. What is a key challenge they will face?

   • AEnsuring that all services use the same programming language
   • BEliminating the need for a message broker
   • CReducing the number of services in the application
