FC0-U71 Practice Question: Which THREE of the following are common methods…
Which THREE of the following are common methods for securing a wireless network?
⚠ Common exam trap
Test-takers frequently think WEP is still acceptable for security because it was once a standard, but the exam expects you to know it is deprecated and easily broken, while changing the IP range is a common misconception that offers no real security benefit.

Correct answer & explanation
✓
Implementing MAC address filtering
MAC address filtering is a common method for securing a wireless network because it allows the administrator to create an allowlist of specific MAC addresses that are permitted to connect to the access point. This prevents unauthorized devices from associating with the network, even if they know the SSID and password. However, it is not foolproof, as MAC addresses can be spoofed using tools like `macchanger`.
