Drag and Drop Question Drag and drop the application protocols from the left onto the transport protocols that is uses on the right. Answer:

The correct answer is TCP: FTP; TCP: SMTP; TCP: SSH; UDP: DHCP; UDP: SNMP; UDP: TFTP. FTP, SMTP, and SSH use TCP because they require reliable, connection-oriented delivery to ensure data integrity - FTP transfers files, SMTP delivers emails, and SSH provides secure remote sessions, all of which cannot tolerate packet loss. DHCP, SNMP, and TFTP use UDP because the

Correct arrangement

TCP: FTP
TCP: SMTP
TCP: SSH
UDP: DHCP
UDP: SNMP
UDP: TFTP

Explanation

FTP, SMTP, and SSH use TCP because they require reliable, connection-oriented delivery to ensure data integrity - FTP transfers files, SMTP delivers emails, and SSH provides secure remote sessions, all of which cannot tolerate packet loss. DHCP, SNMP, and TFTP use UDP because they prioritize speed and low overhead over guaranteed delivery - DHCP broadcasts for IP address assignment before a full network stack is established, SNMP polls network devices quickly, and TFTP is a lightweight file transfer protocol designed for simplicity without the overhead of TCP's handshake.
