Exam DP-500 topic 1 question 124 discussion

I think it should be Web API because of the API key. Check this out: https://learn.microsoft.com/en-us/power-query/connector-authentication#select-an-authentication-method

Basic authentication allows you to pass a username (in this case, the API key) and an optional password in the headers of the request, which is a common method for APIs that require API key-based authentication whereas Anonymous option is used when the API does not require any form of authentication, meaning you don't need to pass an API key in the headers and the question requires API key passed in the headers of the request.

change mind, answer is B The specified API key typically falls under "Basic" authentication rather than anonymous authentication. Basic authentication involves passing a username and password or API key in the request to verify the source of the request. This method is usually used for authentication that requires a certain level of security but does not involve complex OAuth2.0 or Azure AD integration scenarios.

Correct answer is Anonymous, see https://community.fabric.microsoft.com/t5/Desktop/A-web-API-key-can-only-be-specified-when-a-web-API-key-name-is/m-p/547468/highlight/true#M257397
