What of the following is true about the features Lambda@Edge in AWS?

Answer options:

A.It is used specifically for the Edge-based programing language.
B.It is used for running Lambda functions at edge locations defined by S3.
C.It is used for running Lambda functions at edge locations used by CloudFront.
D.It can support any type of programming language.

Answer – C
Option A is incorrect as it is not used for Edge-based programming.
Option B is incorrect because edge locations are part of the CloudFront setup, not S3.
Option C is CORRECT because Lambda@Edge allows you to run Lambda functions at the AWS edge locations in response to CloudFront events. Without Lambda@Edge, customized processing requires requests to be forwarded back to compute resources at the centralized servers. This slows down the user experience.
Option D is incorrect because Lambda@Edge supports only Node.js, which is a server-side JavaScript framework.
