Which methods could the developer use to complete a signed request?
(Choose two.)
Add the signature to an HTTP header that is named Authorization
Add the signature to a session cookie
Add the signature to an HTTP header that is named Authentication
Add the signature to a query string parameter that is named X-Amz-Signature
Add the signature to an HTTP header that is named WWW-Authenticate
Explanations:
The signature must be added to the HTTP header named “Authorization” as per AWS Signature Version 4 specifications. This header includes credentials and additional information required for authentication.
Adding the signature to a session cookie is not a standard method for AWS Signature Version 4. Cookies are generally used for session management and do not comply with the requirements for signed requests.
The header named “Authentication” is not recognized in AWS Signature Version 4. The correct header to include the signature is “Authorization.”
It is acceptable to add the signature to a query string parameter named “X-Amz-Signature.” This method is valid for including the signature when making requests via HTTP GET, particularly when using URL signing.
The header “WWW-Authenticate” is used primarily in the context of authentication challenges (like Basic or Digest authentication) and does not apply to AWS Signature Version 4. The signature should not be placed in this header.
I infer that the answer is:
Add the signature to an HTTP header that is named Authorization
To the best of my knowledge, the answer is:
Add the signature to an HTTP header that is named Authorization
