Loosely Coupled Architectures Quiz

What you'll be asked

1. What is the primary benefit of a loosely coupled architecture in terms of system reliability?
2. When implementing an asynchronous communication pattern between two services using a message queue, which reliability challenge are you primarily addressing?
3. Which design pattern is most effective for ensuring system reliability when a downstream service is performing poorly or experiencing intermittent outages?
4. In a microservices environment, why is 'Service Discovery' considered a critical component for maintaining system reliability?
5. You are designing a distributed system where Service A invokes Service B synchronously. To improve resilience, you implement an idempotent retry policy. What is the most critical side effect you must manage to ensure system integrity?
