FC0-U71 Practice Question: Refer to the exhibit
Exhibit
C:\>ipconfig Windows IP Configuration Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : example.com IPv4 Address. . . . . . . . . . . : 192.168.1.105 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 Wireless LAN adapter Wi-Fi: Media State . . . . . . . . . . . : Media disconnected
Refer to the exhibit. A user is able to browse the internet using the Ethernet connection but not the Wi-Fi. What is the most likely cause?
⚠ Common exam trap
Test-takers frequently confuse 'Not connected' with a disabled adapter or a configuration issue like a missing DNS suffix, but the exhibit clearly shows the Wi-Fi adapter is enabled yet has no IP address, pointing to a lack of network association.

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
✓
The Wi-Fi adapter is not connected to any network
The exhibit shows that the Ethernet interface has an IP address (192.168.1.114) and is connected to the internet, while the Wi-Fi interface shows 'Not connected' with no IP address assigned. Since the user can browse the internet via Ethernet but not Wi-Fi, the most likely cause is that the Wi-Fi adapter is not connected to any network, meaning it has not associated with a wireless SSID or obtained an IP address via DHCP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The Wi-Fi adapter is not connected to any network
Why this is correct
The Ethernet path proves the network and router work, so the fault lies at the wireless link itself. An adapter not associated with any SSID cannot pass traffic, matching the symptom of no Wi-Fi browsing. Association must occur before DHCP or authentication can succeed.
- ✗
The Wi-Fi adapter is disabled
Why it's wrong here
A disabled Wi-Fi adapter would also prevent the wireless connection from appearing or associating, yet the stem shows Ethernet working and Wi-Fi failing at the browsing stage. It is tempting because disabling an adapter is a common quick fix, but that scenario would typically show no wireless networks available at all.
- ✗
The DNS suffix is missing
Why it's wrong here
A missing DNS suffix affects name resolution for specific domains, not general internet browsing, and would impair Ethernet equally. It is tempting because DNS misconfiguration commonly causes browsing failures, but it would not produce a split where wired access succeeds and wireless fails.
- ✗
The default gateway is incorrect
Why it's wrong here
An incorrect default gateway would break Ethernet browsing too, since both interfaces route through the same gateway configuration. It is tempting because gateway errors do cause connectivity loss, but they would affect all adapters equally rather than isolating the fault to Wi-Fi alone.
