CompTIA Network+ (N10-007) — Question 475

The following instructions were published about the proper network configuration for a videoconferencing device:
`Configure a valid static RFC1918 address accordingly to 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

Correct answer: D

Explanation

The correct answer is D, 172.19.0.2, as it falls within the private IP range defined by RFC1918. Option A is an IPv6 link-local address, which is not suitable for this context, while B (100.64.0.1) is part of the Shared Address Space and not a private RFC1918 address. Option C (169.254.1.2) is a link-local address assigned by the Automatic Private IP Addressing (APIPA) and option E (224.0.0.12) is a multicast address, both of which are invalid for this configuration.
