Microservices - Event-Driven ArchitectureWhich component typically stores events for replay in a microservices system?AAPI gatewayBCache memoryCLoad balancerDEvent store or event logCheck Answer
Step-by-Step SolutionSolution:Step 1: Identify storage for eventsEvents are stored in an event store or event log to enable replay.Step 2: Eliminate other optionsCache memory is temporary, load balancer and API gateway do not store events.Final Answer:Event store or event log -> Option DQuick Check:Event storage = Event store/log [OK]Quick Trick: Events are stored persistently in event logs for replay [OK]Common Mistakes:MISTAKESConfusing cache with persistent event storageThinking load balancer stores eventsAssuming API gateway handles event storage
