FC0-U71 Secure its wireless network Practice Question
A company wants to secure its wireless network. Which of the following is the BEST practice?
⚠ Common exam trap
The trap here is that candidates often focus on wireless-specific settings like SSID broadcast or encryption, overlooking the critical importance of securing the administrative interface itself, which is a common and easily exploited vulnerability.

Correct answer & explanation
✓
Change the default administrator password
Changing the default administrator password is the best practice because default credentials are widely known and easily exploited, providing an attacker with full administrative access to the wireless access point or router. This action directly mitigates unauthorized configuration changes, which is a fundamental security measure. In contrast, the other options either weaken security or have no significant protective effect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Broadcast the SSID
Why it's wrong here
Broadcasting SSID makes network visible to all; not a security best practice.
- ✗
Disable MAC filtering
Why it's wrong here
Disabling MAC filtering removes an access control layer.
- ✗
Use WEP encryption
Why it's wrong here
WEP is weak and easily cracked; use WPA2 or WPA3.
- ✓
Change the default administrator password
Why this is correct
Default passwords are well-known; changing them prevents easy access.
