Correct answers - "Stage Variables & Lambda Aliases" : Stage variables are name-value pairs
that you can define as configuration attributes associated with a deployment stage of an API.
They act like environment variables and can be used in your API setup and mapping templates.
With deployment stages in API Gateway, you can manage multiple release stages for each API, such
as alpha, beta, and production. Using stage variables you can configure an API deployment stage
to interact with different backend endpoints.
Incorrect:
"Lambda Versions" - Aliases enable you to abstract the process of promoting new Lambda function
version and becomes more manageable than new versions
"Lambda X-Ray integration" - This is good for tracing and debugging requests so it can be looked
at as a good option for troubleshooting issues in the future
"Mapping Templates" - If you did use this template you can access your stage variables but its
not required to use
