ACSP Peripherals and Printing 4 — Questions and Answers
Question 1: A user's USB-C hub stops working after connecting it to a Mac running macOS Ventura. Which step should you perform first to isolate the issue?
- Replace the hub with a known-good unit immediately
- Test the hub on a different Mac or with a different cable (Correct answer)
- Reinstall macOS to restore USB-C drivers
- Reset the SMC and then try the hub again
Correct answer: Test the hub on a different Mac or with a different cable
Testing with a different Mac or cable isolates whether the issue is with the hub, the cable, or the specific Mac's port.
Question 2: Which macOS feature allows a Mac to act as a printer host so other devices on the network can share that printer?
- AirPrint
- Printer Sharing in System Settings (Correct answer)
- Bonjour Browser
- IPP Everywhere
Correct answer: Printer Sharing in System Settings
Printer Sharing in System Settings (formerly System Preferences) lets a Mac share a locally connected printer over the network.
Question 3: A customer's Magic Mouse is not tracking correctly on their desk surface. What is the most likely cause?
- Low battery causing reduced sensor output
- Incompatible Bluetooth version on the Mac
- Dirty or reflective surface interfering with the optical sensor (Correct answer)
- The mouse needs a firmware update
Correct answer: Dirty or reflective surface interfering with the optical sensor
Optical mice can track poorly on highly reflective, transparent, or dirty surfaces that confuse the sensor.
Question 4: When using an Apple Studio Display connected to a MacBook Pro, a user reports the display's built-in camera is not recognized. What should you check first?
- Camera permissions in System Settings > Privacy & Security
- Whether Thunderbolt firmware is up to date on the display
- If the display's USB-C cable is fully seated in the Thunderbolt port (Correct answer)
- Whether the user has enabled Screen Time restrictions
Correct answer: If the display's USB-C cable is fully seated in the Thunderbolt port
The Studio Display's camera, speaker, and microphone only function when connected via the included Thunderbolt cable that also carries data; a loose connection drops those devices.
Question 5: A user wants to print from their iPhone to a printer on their home Wi-Fi network. Which technology enables this without installing an app?
- Bluetooth printing
- AirPrint (Correct answer)
- USB tethering
- Google Cloud Print
Correct answer: AirPrint
AirPrint is Apple's wireless printing protocol built into iOS and macOS that works with compatible printers over Wi-Fi without additional drivers or apps.
Question 6: A Thunderbolt 3 peripheral is connected to a Mac's Thunderbolt 4 port. What is the expected result?
- The peripheral will not function because the protocols are incompatible
- The peripheral works but is limited to USB 3.1 speeds only
- The peripheral functions normally because Thunderbolt 4 is backward compatible with Thunderbolt 3 (Correct answer)
- macOS will prompt the user to update the peripheral's firmware
Correct answer: The peripheral functions normally because Thunderbolt 4 is backward compatible with Thunderbolt 3
Thunderbolt 4 is fully backward compatible with Thunderbolt 3 devices, so they operate at Thunderbolt 3 speeds.
Question 7: Which command-line tool in macOS can be used to list available printers and their status from the Terminal?
- printutil
- lpstat -p (Correct answer)
- lsusb --printers
- system_profiler SPPrintersDataType only
Correct answer: lpstat -p
`lpstat -p` lists all configured printers and indicates whether each is enabled or disabled.
