After a company rolls out software updates, Ann, a lab researcher, is no longer able to use lab equipment connected to her PC. The technician contacts the vendor and determines there is an incompatibility with the latest IO drivers. Which of the following should the technician perform so that Ann can get back to work as quickly as possible?

A. Reformat and install the compatible drivers.
B. Reset Ann’s equipment configuration from a backup.
C. Downgrade the PC to a working patch level.
D. Restore Ann’s PC to the last known good configuration.
E. Roll back the drivers to the previous version.

Correct Answer: E
Section: Network operations

Explanation:
By rolling back the drivers Ann would be able to use her lab equipment again. To roll back a driver in Windows means to return the driver to the version that was last installed for the device. Rolling back a driver is an easy way to return a driver to a working version when a driver update fails to fix a problem or maybe even causes a new problem. Think of rolling back a driver as a quick and easy way to uninstall the latest driver and then reinstall the previous one, all automatically.
