Wake for network access. This option allows users on another computer can access the shared resources of your Mac and makes your Mac wake from sleep mode at that time.

Enable Power Nap. This enables your MacBook to check email, calendar, and iCloud updates and use Time Machine to back up files even in sleep mode.
