What is a REST API in API Gateway?

• A REST API in API Gateway is used for real-time data processing

• A REST API in API Gateway is a type of database management system

• A REST API in API Gateway is designed for offline data synchronization

• A REST API in API Gateway follows REST principles to define endpoints for clients to interact with resources using HTTP methods.

Explain the caching mechanisms available in API Gateway.

• Edge caching and distributed caching

• Local caching and global caching

• Edge caching and regional caching

• Regional caching and server-side caching

What are the different authorization methods supported by API Gateway?

• API keys

• OAuth tokens

• IAM permissions, resource policies, Lambda authorizers, Amazon Cognito user pools

• SAML assertions

Discuss the various deployment strategies in API Gateway.

• Sunset deployment

• Red-yellow deployment

• Purple deployment

• Canary deployment, blue-green deployment, staged deployment, and shadow deployment.

How do API Gateway usage plans work?

• API Gateway usage plans work by setting unlimited access to all APIs

• API Gateway usage plans work by defining access rules and usage limits for APIs, which can be assigned to different clients or API keys.

• API Gateway usage plans work by randomly assigning access rules to clients

• API Gateway usage plans work by restricting access based on the weather forecast

What are the key aspects of monitoring and logging in API Gateway?

• Tracking API usage, performance metrics, error logs, security audits, and real-time alerts.

• Tracking user preferences

• Analyzing weather patterns

• Sending automated emails

How can you create a REST API in API Gateway?

• Follow the steps provided in the AWS API Gateway documentation to create a REST API.

• Write a letter to Jeff Bezos asking for a REST API to be created

• Use a spreadsheet software to manually input the API endpoints

• Send an email to AWS support requesting the creation of a REST API

What is the purpose of caching in API Gateway?

• To increase security by exposing sensitive data to unauthorized users

• To complicate the API response process

• To slow down the API performance by adding unnecessary steps

• To improve performance by storing responses from the backend server and serving them directly to clients without re-executing the request.

Describe the process of setting up API Gateway authorization using IAM roles.

• Create an S3 bucket and link it to the API Gateway for authorization

• Create an IAM role with required permissions and attach it to the API Gateway as the authorizer.

• Use API Gateway API keys instead of IAM roles for authorization

• Grant full admin access to all users in the IAM roles for API Gateway authorization

Compare the blue/green deployment strategy with canary deployment in API Gateway.

• Blue/green deployment involves routing all traffic to the new version immediately.

• Blue/green deployment involves gradually shifting traffic to the new version by routing a small percentage first.

• Blue/green deployment involves two identical production environments, while canary deployment gradually shifts traffic to the new version by routing a small percentage first.

• Canary deployment involves two identical production environments.
