CompTIA Network+ (N10-007) — Question 480

A technician needs to upgrade a SOHO wireless router's firmware. The technician resets the router to factory settings and installs the new firmware. The technician enters the DHCP information and sets the SSID. Which of the following configurations would provide the MOST protection from advance hackers?

Answer options

• A. Disable the broadcasting of the SSID.
• B. Enable WPA2 authentication for all hosts.
• C. Use private addressing for the DHCP scope.
• D. Install unidirectional antennas.

Correct answer: B

Explanation

Enabling WPA2 authentication for all hosts (option B) provides robust security by encrypting the wireless traffic and requiring authentication for access. Disabling SSID broadcasting (option A) offers minimal security as determined hackers can still discover the network. Using private addressing (option C) and installing unidirectional antennas (option D) do not directly enhance the security of the wireless connection itself.
