FC0-U71 Practice Question: That their laptop cannot connect to the corporate…
A user reports that their laptop cannot connect to the corporate Wi-Fi network. Other users in the same area are connected without issues. The laptop shows it is connected to the Wi-Fi but has no internet access. Which of the following is the MOST likely cause?
⚠ Common exam trap
Many exam-takers confuse a successful Layer 2 association (connected to Wi-Fi) with full Layer 3 connectivity, leading them to choose weak signal or MAC filtering instead of recognizing that the issue is at the IP configuration layer.
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
✓
Incorrect IP configuration
The laptop shows it is connected to Wi-Fi but has no internet access, which indicates that the Layer 3 (network layer) configuration is faulty. An incorrect IP configuration, such as a static IP in the wrong subnet or a failed DHCP lease, prevents the laptop from obtaining a valid default gateway and DNS server, breaking internet connectivity while the Wi-Fi association (Layer 2) remains intact.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Weak Wi-Fi signal
Why it's wrong here
A weak signal would degrade throughput or drop the association entirely, yet the laptop is associated and other users nearby are fine, so signal strength is not the failing layer. It tempts because weak signal is a common Wi-Fi complaint, and it would be correct if the laptop were distant from the access point.
- ✗
SSID broadcast disabled
Why it's wrong here
A hidden SSID prevents the network appearing in the list, but the laptop is already associated to it, so broadcast state is irrelevant. It tempts because hidden SSIDs cause connection failures, and it would be correct if the laptop could not see or join the network at all.
- ✓
Incorrect IP configuration
Why this is correct
Static IP or wrong DHCP settings can cause local connectivity but no internet.
- ✗
MAC address filter enabled
Why it's wrong here
MAC filtering blocks association outright, so the laptop would never show as connected; here it associates but cannot reach the internet. It tempts because filtering is a common access-control cause, and it would be correct if the laptop failed to join while others succeeded.
