  1. A customer wants to transfer files between two Macs at maximum speed. Which method should a technician recommend?

    Answer: Thunderbolt cable in Target Disk Mode

    Thunderbolt in Target Disk Mode provides up to 40 Gbps transfer speeds, far exceeding AirDrop's Wi-Fi bandwidth and external drive transfer rates.

  2. How does Target Disk Mode work on an Intel Mac?

    Answer: The Mac presents its storage as an external drive to another Mac connected via Thunderbolt or FireWire

    Target Disk Mode presents the Mac's internal storage as an external volume to a host Mac via a Thunderbolt or FireWire cable, allowing direct disk access.

  3. Which protocol does Bluetooth use to create a Personal Area Network (PAN) between devices?

    Answer: PAN profile over Bluetooth radio in the 2.4 GHz band

    Bluetooth uses its Personal Area Network (PAN) profile to share internet or local connectivity between devices over the 2.4 GHz Bluetooth radio.

  4. A MacBook's Bluetooth is greyed out and unavailable after a repair. What is the most likely cause?

    Answer: The Bluetooth antenna or its cable was damaged or disconnected during the repair

    Bluetooth sharing the same antenna or having a dedicated cable that can be damaged or disconnected during repair is the most common hardware cause of post-repair Bluetooth failure.

  5. Which macOS command flushes the local DNS cache to resolve domain name resolution issues?

    Answer: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

    On macOS, flushing the DNS cache requires running 'sudo dscacheutil -flushcache' followed by 'sudo killall -HUP mDNSResponder' to clear and restart the DNS resolver.

  6. What does the 'Internet Sharing' feature in macOS System Settings allow?

    Answer: Sharing the Mac's internet connection with other devices via Wi-Fi, Ethernet, or Bluetooth

    Internet Sharing turns the Mac into a router, distributing its internet connection to other devices connected via Wi-Fi hotspot, Ethernet, or Bluetooth.
