The correct answer is D. HTTPS/443.

Amazon WorkSpaces is a managed, secure desktop computing service that runs on the AWS cloud. It allows users to access the applications, documents, and resources they need from any supported device, anywhere in the world.

Authentication is the process of verifying the identity of a user or device attempting to access a resource. Amazon WorkSpaces uses HTTPS/443 to authenticate users. HTTPS is a protocol used for secure communication over the internet. It encrypts data in transit, preventing unauthorized access and ensuring the privacy and integrity of the data being transmitted.

TCP/80 and HTTP/80 are not used for authentication in Amazon WorkSpaces. TCP/80 is used for unencrypted HTTP traffic, while HTTP/80 is used for unencrypted web traffic. However, using unencrypted protocols is not secure and can expose sensitive data to interception and unauthorized access.

UDP/443 is also not used for authentication in Amazon WorkSpaces. UDP is a connectionless protocol that does not provide the same level of security as TCP. Furthermore, UDP/443 is not a standard protocol/port combination, and is not commonly used for secure communication over the internet.

Therefore, the correct answer is D. HTTPS/443.
