AWS Certified Solutions Architect Associate (SAA-C03) - API Gateway

The video tutorial provides an in-depth look at APIs, focusing on AWS API Gateway. It covers the historical context of APIs, their role in cloud management, and how they interact with AWS and external services. The tutorial explains the architecture of API Gateway, emphasizing its serverless nature and integration with Lambda functions. An example illustrates how serverless architecture can automate inventory management. The video also discusses Cross-Origin Resource Sharing (CORS) and its significance in API Gateway operations. Finally, it highlights potential use cases for API Gateway in accessing cloud-stored code.

What is the primary purpose of an API?

• To provide a standardized way to perform tasks

• To create new software from scratch

• To manage hardware resources

• To replace all existing software

Where is the API Gateway located in AWS services?

• In the DevOps tools category

• In the Storage category

• In the Networking and Content Delivery category

• In the Security category

What can APIs interact with besides AWS services?

• Only AWS databases

• Other web services and external data

• Only AWS storage solutions

• Only local files

What is a key feature of serverless architecture?

• It is limited to AWS services

• It only works with EC2 instances

• It eliminates the need for server instances

• It requires constant server management

How do Lambda functions and API Gateway work together?

• They operate independently without interaction

• They are incompatible with each other

• They enable serverless processing of data

• They require manual server setup

What is the role of CORS in API Gateway?

• To allow cross-domain requests

• To limit API usage to AWS services

• To enhance server performance

• To restrict all external requests

In the given example, what triggers the Lambda function?

• A manual server command

• An automatic AWS update

• A directive from a sales application

• A scheduled task
