Networking Fundamentals — Question 47

What is an example of a network device that associates a network address with a port?

Answer options

• A. Switch
• B. Router
• C. Hub
• D. DSL modem

Correct answer: B

Explanation

A Router is designed to connect different networks and manage traffic between them by using IP addresses and routing tables, thereby associating network addresses with specific ports. In contrast, a Switch operates at the data link layer and forwards data based on MAC addresses, a Hub broadcasts to all ports without any addressing, and a DSL modem is primarily for connecting to the internet.
