What the System Architecture interview quiz covers

This quiz tests your knowledge of distributed system design and high-scale software engineering: microservices, service decoupling, and network protocols.

It covers resilience patterns (Circuit Breaker, Rate Limiting, Retry with exponential backoff and jitter), distributed transaction consistency (Saga Pattern), distributed observability (OpenTelemetry), and multi-layer caching.

Difficulty levels

Beginner covers service architecture fundamentals, REST vs gRPC trade-offs, load balancers, and caching patterns (Cache-Aside, Write-Through).

Intermediate explores resilience design, Circuit Breakers, rate limiting algorithms (Token Bucket, Leaky Bucket), idempotency, and backpressure.

Advanced challenges your ability to design large-scale microservice ecosystems, Service Meshes, Chaos Engineering, distributed tracing, and fault-tolerant backends.

Question topics covered

  • Modular monolith vs microservices trade-offs
  • Communication protocols: REST vs gRPC vs GraphQL
  • Circuit Breaker states: Closed, Open, and Half-Open transitions
  • Rate limiting algorithms (Token Bucket, Leaky Bucket, Sliding Window)
  • Idempotency guarantees with idempotent API keys
  • Observability pillars: metrics, structured logging, and distributed tracing
