CompTIA A+ Core 1 (220-1001) — Question 243
A customer travels often and needs to connect a laptop to the home office server. The customer wants to use a cell phone data connection but has connected to the wrong network in the past. Which of the following would work BEST to ensure a secure connection through the cell phone?
Answer options
- A. Bluetooth with PIN
- B. Tethering with USB
- C. Hotspot with WPA
- D. Public WiFi with password
Correct answer: B
Explanation
The best option is B, Tethering with USB, because it provides a direct and secure connection to the laptop without exposing it to external networks. Option A, Bluetooth with PIN, is less secure and has limited range, while C, Hotspot with WPA, can still be vulnerable to interception. Option D, Public WiFi with password, is the least secure as public networks are often targeted for attacks.
