CompTIA Network+ (N10-008) — Question 103

The following instructions were published about the proper network configuration for a videoconferencing device:
"Configure a valid static RFC1918 address for your network. Check the option to use a connection over NAT."
Which of the following is a valid IP address configuration for the device?

Answer options

• A. FE80::1
• B. 100.64.0.1
• C. 169.254.1.2
• D. 172.19.0.2
• E. 224.0.0.12

Correct answer: D

Explanation

The correct answer, D, 172.19.0.2, is an RFC1918 address, which is suitable for private networks. Options A (link-local), B (shared address space), C (link-local), and E (multicast) do not conform to the RFC1918 standard for private addressing.
