CompTIA Network+ (N10-007) — Question 152

A small business utilizes a SOHO router and wishes to secure its existing wireless infrastructure. The business has fewer than ten devices, which are a mixture of old and new machines. Due to the varying ages of the machines, the latest wireless encryption methods may not be supported on all devices. Which of the following would be the MOST cost-effective method to add a layer of security while allowing all machines to connect?

Answer options

• A. WPA2
• B. EAP-FAST
• C. MAC filtering
• D. 802.1X

Correct answer: A

Explanation

WPA2 is the most cost-effective encryption method that provides strong security while being widely supported by both old and new devices. EAP-FAST and 802.1X are more complex and may not be necessary for a small business with fewer devices, while MAC filtering does not provide robust security as it can be easily bypassed.
