CompTIA Network+ (N10-009) — Question 274

A newly opened retail shop uses a combination of new tablets, PCs, printers, and legacy card readers. Which of the following wireless encryption types is the most secure and compatible?

Answer options

• A. WPA3
• B. WPA2
• C. WPA2 / WPA3 mixed mode
• D. WPA / WPA2 mixed mode

Correct answer: C

Explanation

WPA2 / WPA3 mixed mode (Option C) provides a balance of security and compatibility, allowing both legacy and modern devices to connect securely. WPA3 (Option A) is the most secure but may not support older devices, while WPA2 (Option B) lacks the enhanced security features of WPA3. WPA / WPA2 mixed mode (Option D) is outdated and less secure compared to the mixed mode of WPA2 and WPA3.
