CompTIA Network+ (N10-007) — Question 628

An administrator implemented a wireless network in a warehouse for an employee to scan inventory as it arrives and is shipped out. The scanners are proprietary devices that connect to the wireless network, but they have no configuration options beyond connecting via DHCP. Which of the following should the administrator implement to harden the wireless network without negatively affecting the scanners' ability to connect?

Answer options

• A. Secure the wireless network using PEAP authentication for connecting devices.
• B. Implement a two-factor authentication method for the wireless network.
• C. Allow only devices with statically assigned IP addresses to connect to the network.
• D. Configure the wireless network to allow connections based on hardware address only.

Correct answer: D

Explanation

The correct answer is D because configuring the network to allow connections based on hardware addresses (MAC filtering) can enhance security while still allowing the proprietary scanners to connect via DHCP. Options A and B are not suitable as they require configurations that the scanners do not support, and option C would prevent the scanners from connecting since they rely on DHCP.
