FC0-U71 Practice Question: A user can access the internet and other…
A user can access the internet and other computers on the network but cannot print to a network printer that is on the same subnet. The printer's IP is 192.168.1.100. What is the most likely cause?
⚠ Common exam trap
Watch out — candidates often assume a network configuration issue (like DNS or subnet mask) is the cause, overlooking the simplest physical-layer problem—a powered-off device—which is a common CompTIA troubleshooting focus.

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 printer is powered off
If the printer is powered off, it cannot respond to print jobs, yet the user can still access the internet and other computers on the network since those services are independent of the printer. The printer's IP address (192.168.1.100) being on the same subnet means that connectivity to it relies solely on the printer being powered on and operational at Layer 2 (Ethernet) and Layer 3 (IP). A powered-off printer will not respond to ARP requests or TCP connections, causing print jobs to fail while other network functions remain unaffected.
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 router is not forwarding print jobs
Why it's wrong here
Print jobs on the same subnet do not traverse the router.
- ✗
The user's computer has a wrong subnet mask
Why it's wrong here
A wrong subnet mask would affect all network communication, not just the printer.
- ✗
The printer's DNS is misconfigured
Why it's wrong here
DNS is not required for local subnet communication.
- ✓
The printer is powered off
Why this is correct
A powered-off printer is unreachable, while other network functions work.
