   A small company has a simple internal tool used by a few dozen employees. The tool is a single application that handles user authentication, data entry, and reporting. The company has no dedicated DevOps team and wants to minimize deployment complexity. They expect the tool's functionality to remain stable for the next few years. Which architectural pattern is most appropriate?

   • AMonolithic architecture
   • BService-oriented architecture with an ESB
   • CMicroservices architecture
   • DEvent-driven architecture

   Compared to a monolithic architecture, what is a primary advantage of a microservices architecture?

   • ALower operational complexity because there are fewer moving parts.
   • BEasier to maintain because all code is in one codebase.
   • CSimpler deployment because there is only one artifact to manage.
   • DBetter scalability because individual services can be scaled independently.

   A startup is building a new e-commerce platform. The team is small (5 developers) and wants to launch a minimum viable product (MVP) quickly. They expect the product to grow, but they are not yet sure which parts will need the most scaling. The CTO wants to avoid the operational overhead of managing many services and databases initially. Which architectural approach best meets these constraints?

   • AMicroservices architecture with a separate database per service
   • BService-oriented architecture with an enterprise service bus
   • CEvent-driven architecture with multiple event brokers
   • DMonolithic architecture with a modular internal structure

   A company has a microservices-based application where the 'order' service needs to notify the 'inventory' service and the 'notification' service when a new order is created. The company wants to avoid the order service having to know the addresses of the other services. They also want to ensure that if the notification service is temporarily down, the order service is not affected. Which communication pattern best meets these requirements?

   • APublish an 'OrderCreated' event to a message broker; inventory and notification services subscribe to that event
   • BUse synchronous REST calls from the order service to the inventory and notification services
   • CUse a shared database where the order service writes and the other services poll for changes
   • DUse a service mesh with direct calls to each service
