Q1. A developer is building a web application where users upload profile photos. The photos must be stored durably, scale to millions of files, and be served to browsers over HTTPS. Which AWS service should store the photos?
Select one answer before revealing.
Q2. A developer needs to run backend code in response to events such as file uploads, without provisioning or managing any servers, and wants to be billed only for the compute time actually consumed. Which AWS service meets these requirements?
Select one answer before revealing.
Q3. An application requires a fully managed NoSQL database that provides single-digit millisecond latency for key-value lookups and scales automatically as traffic grows, with no instance management. Which service should the developer choose?
Select one answer before revealing.
Q4. A developer has implemented business logic in AWS Lambda and must expose it to client applications as a RESTful HTTPS API with request throttling and API key support. Which service should sit in front of the Lambda function?
Select one answer before revealing.
Q5. A web application experiences traffic spikes that overwhelm its order-processing backend, causing dropped orders. The developer wants to decouple the front end from the backend so orders are buffered durably and processed asynchronously at the backend's own pace. Which service is designed for this?
Select one answer before revealing.
Q6. When a new order is placed, an application must immediately push the event to several downstream systems at once, each of which processes it independently. Which service provides this push-based, one-to-many message delivery?
Select one answer before revealing.
Q7. A Lambda function needs to read items from a single DynamoDB table. Following AWS best practices, how should the developer grant the function this access?
Select one answer before revealing.
Q8. A developer is adding authentication to a mobile app. The app needs user sign-up and sign-in with email verification, MFA, and social login with Google — without the team building or operating its own identity backend. Which AWS service should they use?
Select one answer before revealing.
Q9. A company requires that application data stored in Amazon S3 and DynamoDB be encrypted at rest using centrally managed keys, and that every use of those keys be recorded for compliance auditing. Which AWS service provides this key management and usage auditing?
Select one answer before revealing.
Q10. An application currently stores its Amazon RDS database credentials in a configuration file. A new security policy requires the credentials to be stored encrypted and rotated automatically every 30 days without application downtime. Which AWS service should the developer use?
Select one answer before revealing.
