Which AWS service publishes HTTP/REST and WebSocket APIs in front of Lambda, EC2, or any HTTP backend, with built-in authorisation, throttling, and request validation?
AAmazon ElastiCache for Redis

Answer & Solution
Correct answer: B. Amazon API Gateway
API Gateway is the managed API façade — handles auth, rate-limiting, validation, and request transformation. Direct Connect is private fibre, ElastiCache is an in-memory cache, Polly is text-to-speech.
