- Match each requirement to the AWS service or feature that meets it best.Medium
- A platform must ingest millions of IoT sensor readings per hour and query them with time-range scans. Which AWS database is purpose-built for this workload?Medium
- A Lambda function processing financial transactions sees 3-5 second cold starts and misses a 200 ms response requirement for business-critical requests. Which feature minimizes cold starts?Medium
- A company streams live sporting events to millions of concurrent viewers worldwide with minimal buffering. Which CloudFront configuration suits live video delivery?Hard
- A web application must push stock price updates to thousands of connected users with sub-second latency, in a read-heavy pattern with one writer and many readers. Which AWS service is optimized for this publish-subscribe, real-time delivery pattern?Hard
- An application serves personalized content and its APIs must authenticate requests carrying JSON Web Tokens (JWTs) issued by a third-party identity provider such as Auth0. The authentication must happen at the API layer, without custom verification code in each microservice. Which AWS service handles JWT validation there?Medium
- A bioinformatics workload requires maximum single-threaded CPU performance for a genomic sequencing algorithm, with jobs that run 2–4 hours. Which EC2 instance family fits best?Easy
- A CloudFront distribution serves both video files (already-compressed MP4 and HLS) and text assets such as JavaScript and CSS. The goal is to reduce bandwidth on the compressible assets without touching video delivery. How should automatic compression be configured?Medium
- A DynamoDB table's primary key is composed of a product identifier and an order date. Items must also be queried by customer identifier sorted by order date, which the primary key cannot serve. What is the native DynamoDB solution?Easy
