正解:
devnet:Cisco123, Basic
Explanation:
Solution as below
When using Basic Authentication in HTTP, the username and password are concatenated with a colon (:) in between. This concatenated string is then encoded using Base64. For the provided username devnet and password Cisco123, the string devnet:Cisco123 is encoded in Base64, resulting in ZGV2bmV0OkNpc2NvMTIz. This Base64 string is then included in the HTTP Authorization header. This process is described in the RFC 7617 and is a standard practice in HTTP Basic Authentication.
