FC0-U71 Practice Question: Refer to the exhibit
Exhibit
C:\Users\Tech> ipconfig Windows IP Configuration Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : IPv4 Address. . . . . . . . . . . : 192.168.1.101 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1
Refer to the exhibit. A technician is troubleshooting a connectivity issue. The user can access local resources but cannot reach the internet. Based on the output, what is the most likely cause?
⚠ Common exam trap
CompTIA often tests the distinction between a missing default gateway (which breaks all off-subnet traffic) and a missing DNS server (which breaks name resolution but allows IP-based access), and the trap here is that candidates assume internet access requires only a default gateway, overlooking that most internet access relies on DNS to resolve domain names.
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
✓
Missing DNS server configuration
The user can access local resources but cannot reach the internet, which indicates that local network communication (e.g., ARP, broadcast) is functioning, but name resolution is failing. The output likely shows that the DNS server configuration is missing or incorrect, preventing the resolution of internet domain names to IP addresses. Without a valid DNS server, the user cannot translate URLs like www.example.com into routable IP addresses, even if the default gateway and IP configuration are correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
No default gateway
Why it's wrong here
A default gateway (192.168.1.1) is present.
- ✗
IP address conflict
Why it's wrong here
No evidence of conflict; the IP is unique.
- ✗
Incorrect subnet mask
Why it's wrong here
The subnet mask matches a typical /24 network.
- ✓
Missing DNS server configuration
Why this is correct
No DNS server is shown; without DNS, internet hostnames cannot be resolved.
