What two preventive maintenance tasks should be scheduled to occur automatically? (Choose two.)

• executing a backup
• scanning the signature files
• updating the operating system software
• resetting devices by applying the factory reset feature
• checking the disks for bad sectors
  

  Answers Explanation & Hints: To avoid the loss of irreplaceable information, it is critical that regular backups be executed and that the hard drives be checked regularly. The signature files are scanned constantly by antimalware software. Updating the OS should happen when necessary but should not occur automatically. Because the factory reset of a device deletes all settings and user data, a factory reset should only be done if a major issue requires it.
