   A team is designing an event-driven system where events must be processed in the exact order they were generated, and each event must be processed exactly once. Which event handling approach should they choose?

   • AUse a topic with multiple partitions and assign each partition to a different consumer group.
   • BUse a single partition and a single consumer group, ensuring one consumer processes events sequentially.
   • CUse a queue with multiple competing consumers.
   • DUse a topic with multiple partitions and multiple consumers per partition.

   What is a key benefit of using an event-driven architecture in a cloud application?

   • AIt allows components to be decoupled and scaled independently.
   • BIt guarantees data consistency across all services.
   • CIt reduces the need for monitoring and logging.
   • DIt simplifies the overall system design by removing the need for a broker.

   A team is evaluating whether to adopt an event-driven architecture for a new application. They are concerned about the complexity of debugging and tracing events across multiple services. Which challenge of event-driven architectures should they plan for?

   • AEvent brokers are always more expensive than direct API calls.
   • BEvent-driven architectures cannot handle high throughput.
   • CDistributed tracing is difficult because events flow asynchronously through multiple components.
   • DEvent-driven architectures do not support microservices.
