A and C. After creating an user pool "API Gateway doesn't know that the requests should made only by authenticated users". So we need to create a cognito authorizer in API Gateway, by specifing the user pool already created (A is correct). Then, we do need to specify the authorizer (created in the previous step) in the GET method of our endpoint and redeploy the service (C is correct)

A. Create an Amazon Cognito authorizer in API Gateway and specify the Amazon Cognito user pool: An authorizer in API Gateway is responsible for verifying incoming requests before they reach your API's backend. By creating an Amazon Cognito authorizer and specifying the user pool, the API Gateway will authenticate the user's credentials with the Amazon Cognito user pool. C. Specify the authorizer in the GET method section of API Gateway and redeploy the API: After creating the authorizer, the developer should specify it in the GET method section of the API Gateway. The authorizer will then be invoked on all incoming requests to the API. The API Gateway will then return a 401 Unauthorized status response for any unauthenticated requests.

I believe it’s A,C After the user pool is created in Cognito, an authorizer will need to be created in API Gateway for Cognito (not Lambda) specifying a user pool. Then, redeploying the API after the changes will allow the changes to take effect.
