Which cloud solution should be selected for these requirements? A. multi B. public C. private D. hybrid 18. A REST API service requires authentication based on the username and password. The user “john” has the password “384279060” and the Base64 encoding of those credentials is “am9objowMTIzNDU2Nzg=”. Which method completes an authentication request? A.
