CompTIA Network+ (N10-007) — Question 249

A technician set up a small network, which is not connected to the company LAN, for several employees to play a peer-to-peer networking game during breaks.
The users know how to set up the software, but they do not know anything about networking. The technician has wired the network but has not configured any networking information and does not want the employees to have access outside the network. Which of the following should be used to apply addressing to the network?

Answer options

• A. NAT
• B. VLSM
• C. APIPA
• D. CIDR

Correct answer: C

Explanation

APIPA (Automatic Private IP Addressing) is suitable for environments where devices need to communicate on a local network without external access, as it automatically assigns IP addresses in the 169.254.x.x range. NAT, VLSM, and CIDR are not appropriate here since they either involve internet connectivity or complex subnetting that the employees are not equipped to handle.
