CompTIA A+ Core 2 (220-1002) — Question 368

Which of the following wireless security protocols supports the use of a 40-bit encryption key?

Answer options

• A. TKIP
• B. WEP
• C. WPA
• D. WPA2

Correct answer: B

Explanation

WEP (Wired Equivalent Privacy) is known for its use of a 40-bit encryption key, which is considered weak by today's standards. TKIP, WPA, and WPA2 use stronger encryption methods and do not support a 40-bit key, making WEP the correct answer in this context.
