CompTIA A+ Core 1 (220-1001) — Question 166

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

Answer options

• A. SNMP
• B. AFP
• C. TCP
• D. SSH

Correct answer: C

Explanation

TCP is a fundamental protocol that does not have a specific port number assigned to it, as it is used as a transport layer protocol. In contrast, SNMP, AFP, and SSH are application layer protocols that do operate with specific port assignments, making them dependent on port numbers for their functionality.
