CompTIA A+ Core 1 (220-1101) — Question 186

Which of the following protocols operates without a port number assignment?

Answer options

• A. SNMP
• B. TCP
• C. SSH
• D. DHCP

Correct answer: B

Explanation

TCP is a protocol that does not use a specific port number assignment for its operations, as it establishes communication sessions based on the connection rather than a fixed port. In contrast, SNMP, SSH, and DHCP are all protocols that do rely on designated port numbers for their functionality.
