A. B. C. D. E.Correct Answer: D
UPD needs Storage Spaces Direct (S2D) to meet the performance requirements.
It is a Server Message Block (SMB) protocol that is used by UPD.
Here, the profile is copied to the Virtual Machine in which the target user is being logged.
Option A is incorrect.
UPD doesn't use SMTP protocol.
Option B is incorrect.
UPD doesn't use the UDP protocol.
Rather, it uses SMB protocol.
Option C is incorrect.
Telnet is not the right protocol to be used by UPD.Option D is correct.
It is a Server Message Block (SMB) protocol that is used by UPD.Option E is incorrect.
Gopher protocol is not used by UPD.Reference:

User Profile Disk (UPD) is a technology used in RDSH and VHD environments to store user profiles. It allows users to maintain their personalized desktop and application settings across multiple sessions by creating a separate disk image for each user on a file share.
When a user logs on to a Remote Desktop Session Host (RDSH) server or Virtual Desktop Infrastructure (VDI) session, a UPD is attached to their session. Any changes made by the user to their desktop settings or applications are stored in their UPD. When the user logs off, the UPD is detached from the session and stored on the file share.
To access the UPD, the RDSH server or VDI broker uses the Server Message Block (SMB) protocol, which is a network file sharing protocol. SMB is used to allow the RDSH server or VDI broker to access the file share where the UPD is stored and to read or write to the UPD for the user's session.
SMTP (Simple Mail Transfer Protocol) is a protocol used for email communication, Telnet is a protocol used for remote terminal access, and Gopher is an obsolete protocol for retrieving information from the internet. None of these protocols are used by UPD.
User Datagram Protocol (UDP) is a connectionless protocol that is used for low-latency, loss-tolerant communications. While UDP is used for some network services, it is not used by UPD.
In summary, the protocol used by User Profile Disk (UPD) is Server Message Block (SMB).
