Exam 312-49v10 topic 1 question 65 discussion

Revised Answer: B Explanation: (A) Port 7 ❌ Used for Echo Protocol, not netstat. (B) Port 15 ✅ Historically assigned to netstat, though rarely used today. (C) Port 23 ❌ Used for Telnet, not netstat. (D) Port 69 ❌ Used for TFTP, unrelated to netstat. Port 15 was originally assigned to netstat by the IANA (Internet Assigned Numbers Authority) but was later deprecated. The assignment of Port 15 for netstat dates back to early networking implementations. Over time, it became unused and unmaintained, leading to its deprecation. Modern versions of netstat do not rely on a specific port; instead, they analyze active TCP/UDP connections and listening services on various ports.
