FC0-U71 Practice Question: That their laptop cannot connect to the office…
A user reports that their laptop cannot connect to the office Wi-Fi. Other devices connect fine. The technician checks the wireless adapter status in Device Manager and sees a yellow exclamation mark. The technician attempts to update the driver but receives an error that the best driver is already installed. What should the technician do next?
⚠ Common exam trap
Many exam-takers assume 'best driver already installed' means the driver is fine, but the yellow exclamation mark explicitly contradicts that, and they overlook the rollback option in favor of generic troubleshooting or hardware replacement.

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
✓
Roll back the driver to a previous version
The yellow exclamation mark in Device Manager indicates a driver problem. Since updating the driver fails with 'best driver already installed,' the issue is likely a faulty or incompatible driver version. Rolling back the driver restores the previous working version, which is the correct next step before considering hardware replacement.
