What can firmware updates cause to reset in a device such as a router?

• A. Firmware updates
• B. Antivirus updates
• C. Disk defragmentation
• D. User password changes

Answer: (A)

Firmware updates require restarting the device so the new code can initialize and run. When the update finishes, the router reboots and starts up with the updated firmware, effectively resetting its running state to apply the changes. This reboot during an update is normal and is the primary way the update takes effect. Other actions like antivirus updates, disk defragmentation, or changing a user password don’t inherently trigger a reset of the router’s firmware behavior; they address different systems or settings and don’t force the device to restart to apply the update.
