SK0-004 · Question #279
After applying a new driver to a NIC, the server reboots and fails to restart. Which of the following is the BEST way to resolve the problem?
The correct answer is B. Boot the server, press F8 and access last known good configuration. When a newly installed driver causes a boot failure, accessing Last Known Good Configuration via F8 at startup reverts the system registry to its last successful state, restoring the previous driver.

Why each option
When a newly installed driver causes a boot failure, accessing Last Known Good Configuration via F8 at startup reverts the system registry to its last successful state, restoring the previous driver.
While the recovery console can manually replace driver files, it requires complex command-line steps and is a slower, more error-prone approach compared to the automated Last Known Good Configuration rollback.
Pressing F8 during boot and selecting Last Known Good Configuration restores the HKLM\System\CurrentControlSet registry hive to the state captured at the last successful logon, effectively rolling back the faulty NIC driver without manual file manipulation. This is the fastest and most targeted recovery option for a driver-related boot failure because it directly undoes the problematic registry change. No data loss occurs and no additional recovery media is required.
Restoring from a backup tape is a last-resort measure that causes data loss for everything created since the last backup, making it disproportionate for reversing a single driver change.
ASR (Automated System Recovery) performs a full system rebuild from backup and is designed for catastrophic failures, not for rolling back a single driver update.
