FC0-U71 Practice Question: Which three of the following are recommended…
Which three of the following are recommended practices for securing a home wireless network? (Choose three.)
⚠ Common exam trap
Candidates often think MAC address filtering is a strong security measure, but CompTIA tests the understanding that it is easily bypassed and not a recommended practice for securing a home wireless network.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disable SSID broadcast
Disabling SSID broadcast makes the network name invisible in client scans, reducing casual discovery. However, it is a weak security measure because attackers can still detect the SSID using packet sniffing tools like Wireshark or airodump-ng when a client connects. It should be used as a minor deterrent, not a primary security control.
