Which ports are required for remote installation?

• A. HTTP Port
• B. TCP and UDP Ports
• C. SSH Port
• D. FTP Port

Answer: (B)

Remote installation relies on two kinds of communication: a reliable, connection-oriented path for commands, files, and status messages, and a lightweight discovery path that can locate devices without establishing a full connection. TCP provides the former, delivering dependable delivery and ordering of data essential for the installation process. UDP provides the latter, allowing fast, broadcast-style discovery and quick signaling without the overhead of a full connection. If you only have one type of port available, the deployment can’t both discover endpoints efficiently and carry installation traffic reliably, so the process would fail to complete on many machines. That’s why ports for both TCP and UDP are required for remote installation. Options that focus on a single protocol (like HTTP, SSH, or FTP) don’t cover the full workflow needed to push and manage agents across a network.
