FC0-U71 A technician installs a new network printer Practice Question
A technician installs a new network printer. It can communicate with other computers on the same network but no one outside the network can access it. What is the MOST likely cause?
⚠ Common exam trap
Many candidates confuse a firewall blocking external traffic with a network connectivity issue, such as a faulty cable or missing IP address, but the key clue is that local communication works fine, isolating the problem to external access control.

Correct answer & explanation
✓
Firewall blocking external traffic
A firewall is designed to control incoming and outgoing network traffic based on predetermined security rules. If the printer can communicate locally but not with external networks, the most likely cause is that the firewall is blocking inbound traffic from outside the local subnet, preventing external devices from reaching the printer's IP address or port.
