The correct answer is C. SSH. SSH provides encrypted, secure remote access to a computer's command-line interface over a network, enabling a technician to manage systems remotely. For remote access scenarios requiring security, SSH is the preferred protocol over unencrypted alternatives.

Why each option
SSH provides encrypted, secure remote access to a computer's command-line interface over a network, enabling a technician to manage systems remotely. For remote access scenarios requiring security, SSH is the preferred protocol over unencrypted alternatives.
VNC (Virtual Network Computing) allows graphical desktop sharing where both the local user and remote technician can simultaneously view and control the desktop - this actually matches the stated requirement of simultaneous visibility more directly than SSH.
Telnet provides unencrypted command-line remote access, transmitting all data including passwords in plaintext, making it unsuitable for secure remote administration of any system.
SSH (Secure Shell) establishes an encrypted channel between the technician's system and the remote computer, protecting all transmitted data including credentials from interception. It is the industry-standard secure remote administration protocol, supporting interactive shell sessions, file transfers, and port forwarding, making it the secure choice for remote access to desktop computers.
RDP (Remote Desktop Protocol) establishes a remote graphical session but typically takes exclusive control of the session, disconnecting or locking the local user out while the technician is connected, preventing simultaneous use.
