Microservices - Event-Driven ArchitectureWhich scenario best illustrates a request-driven microservice interaction?AService A publishes an event and continues without waitingBService A logs an event for auditing purposesCService A sends a command and waits for Service B's response immediatelyDService A stores data locally without contacting other servicesCheck Answer
Step-by-Step SolutionSolution:Step 1: Identify request-driven behaviorRequest-driven means a service sends a request and waits for a response before proceeding.Step 2: Match scenario to request-drivenService A sending a command and waiting for Service B's immediate response fits request-driven interaction.Final Answer:Service A sends a command and waits for Service B's response immediately -> Option CQuick Check:Request-driven example = B [OK]Quick Trick: Waiting for response means request-driven [OK]Common Mistakes:MISTAKESConfusing event publishing with request callsIgnoring the waiting behaviorAssuming logging is communication
