An API gateway is a server that serves as a single entry point for managing and routing API requests from clients to multiple backend services. It handles key functions such as authentication, rate limiting, load balancing, caching, and protocol translation, making it easier to secure, monitor, and scale applications in a microservices architecture. By centralizing these operations, an API gateway simplifies API management, reduces latency, and enhances the overall user experience while abstracting the complexity of the underlying services.

4. How does AWS API Gateway handle authentication for APIs?
A) Only through custom code
B) Using AWS Cognito, Lambda authorizers, or API keys
C) By automatically generating usernames and passwords
D) Through direct integration with social media logins
Answer: B
Explanation: API Gateway supports multiple authentication methods, including AWS Cognito for user pools, Lambda authorizers for custom logic, and API keys for simple access control.
5. What feature of AWS API Gateway allows you to limit the number of requests a client can make?
A) API versioning
B) Throttling
C) Caching
D) Logging
Answer: B
Explanation: Throttling in API Gateway sets rate limits and burst limits to prevent abuse and ensure fair usage of API resources.
6. Which endpoint type in AWS API Gateway is optimized for global access?
A) Regional endpoint
B) Edge-optimized endpoint
C) Private endpoint
D) Public endpoint
Answer: B
Explanation: Edge-optimized endpoints use Amazon CloudFront to distribute API traffic globally, reducing latency for users around the world.
7. What is the role of API Gateway in integrating with AWS Lambda?
A) It replaces Lambda functions entirely
B) It acts as a trigger for Lambda functions and handles API requests
C) It stores Lambda code
D) It monitors Lambda execution times only
Answer: B
Explanation: API Gateway can invoke AWS Lambda functions in response to API requests, serving as a front door for serverless applications.
8. How can you cache responses in AWS API Gateway?
A) By enabling caching at the API level
B) Through manual database queries
C) By using external CDN services
D) Caching is not supported
Answer: A
Explanation: API Gateway provides built-in caching to store responses from backend services, improving performance and reducing latency for repeated requests.
9. What is a usage plan in AWS API Gateway?
A) A blueprint for API design
B) A way to define and enforce quotas and throttling for API keys
C) A schedule for API maintenance
D) A log of API usage history
Answer: B
Explanation: Usage plans allow you to set throttle and quota limits for specific API keys, helping manage and monetize API access.
10. Which protocol is commonly used with AWS API Gateway for simple, stateless interactions?
A) WebSocket
B) MQTT
C) HTTP/HTTPS
D) TCP
Answer: C
Explanation: API Gateway supports HTTP/HTTPS protocols for RESTful and HTTP APIs, which are ideal for stateless, client-server communications.
11. What does AWS API Gateway use to transform and manipulate request/response data?
A) Mapping templates
B) Direct SQL queries
C) Custom JavaScript files
D) API scripts
Answer: A
Explanation: Mapping templates in API Gateway allow you to use Velocity Template Language (VTL) to modify the structure of requests and responses.
12. How can you monitor API performance in AWS API Gateway?
A) Only through third-party tools
