FC0-U71 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. ipconfig output: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : example.com IPv4 Address. . . . . . . . . . . : 192.168.1.100 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1
Refer to the exhibit. A user can ping 192.168.1.1 but cannot ping 8.8.8.8. What is most likely the issue?
⚠ Common exam trap
CompTIA often tests the distinction between local connectivity (Layer 2/3 within subnet) and external routing (Layer 3 beyond the gateway), and the trap here is that candidates confuse DNS resolution with IP reachability, selecting DNS even though the ping uses a raw IP address.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The default gateway is not forwarding traffic to external networks
The user can ping the local gateway (192.168.1.1), which confirms that the local IP configuration, subnet mask, and ARP resolution are working correctly. However, the inability to ping 8.8.8.8 (a public IP) indicates that traffic is not being routed beyond the local subnet. The most likely cause is that the default gateway is either misconfigured, down, or not performing IP forwarding to external networks, as the gateway is the router responsible for forwarding packets destined outside the local network.
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 default gateway is not forwarding traffic to external networks
Why this is correct
The gateway is reachable but may not have a route to the internet.
- ✗
IP address is invalid
Why it's wrong here
The IP address is valid and within the subnet.
- ✗
Subnet mask is incorrect
Why it's wrong here
The subnet mask is standard and correct.
- ✗
DNS server is not configured
Why it's wrong here
Pinging an IP does not require DNS.
