AWS Solutions Architect Interview Scenarios
Scenario — Reliable event processing
Design an event-driven AWS workload where downstream processing can become temporarily unavailable.
Discuss:
- Durable decoupling.
- Retry and dead-letter behavior.
- Idempotency.
- Back-pressure.
- Observability.
- Least-privilege IAM.
Follow-up: What happens when the downstream service is unavailable for an extended period?
Scenario — Secure data access
Design access to sensitive data for multiple application roles.
Explain identity boundaries, least privilege, encryption, audit evidence, and how you would test the policy.
