- Replace the battery immediately
- Check Battery Health in Settings and review per-app battery usage (Correct answer)
- Restore the iPhone to factory settings
- Disable all background app refresh globally
Correct answer: Check Battery Health in Settings and review per-app battery usage
Battery Health and per-app usage data in Settings > Battery helps identify whether the issue is battery degradation or a specific misbehaving app before taking more drastic steps.
Question 2: Which macOS feature allows a Mac to share its internet connection over Wi-Fi while connected to Ethernet?
- AirDrop
- Internet Sharing (Correct answer)
- Personal Hotspot
- Network Bridge
Correct answer: Internet Sharing
Internet Sharing in System Settings > General > Sharing lets a Mac share its Ethernet connection as a Wi-Fi hotspot to other devices.
Question 3: A Mac displays a flashing question mark folder at startup. What does this indicate?
- The display firmware needs updating
- macOS cannot locate a valid startup disk (Correct answer)
- The keyboard is not recognized
- Secure Boot is preventing startup
Correct answer: macOS cannot locate a valid startup disk
A flashing question mark folder means the Mac's firmware cannot find a bootable macOS installation on any connected storage.
Question 4: An iPhone is stuck in a reboot loop and does not respond to a normal restart. Which action should a support professional recommend first?
- Connect to iTunes and perform a DFU restore immediately
- Force restart using the correct button combination for the iPhone model (Correct answer)
- Remove and reinsert the SIM card
- Boot into Recovery Mode and erase the device
Correct answer: Force restart using the correct button combination for the iPhone model
A force restart (model-specific button sequence) is the least destructive first step and often breaks a boot loop without data loss.

- Apple Configurator 2
- Apple Diagnostics (Correct answer)
- System Information
- Activity Monitor
Correct answer: Apple Diagnostics
Apple Diagnostics (launched by holding the power button at startup on Apple Silicon Macs) tests hardware components and returns reference codes for identified issues.
Question 6: A customer wants to use the same Apple ID on a new iPhone while keeping their old iPhone active. What is the maximum number of devices that can be signed into one Apple ID simultaneously?
- 5
- 10 (Correct answer)
- 15
- 20
Correct answer: 10
An Apple ID supports up to 10 trusted devices signed in simultaneously across iCloud and Apple services.
Question 7: A user's iPad cannot connect to a WPA3 Enterprise Wi-Fi network. After verifying credentials are correct, what should the technician check next?
- Disable Private Wi-Fi Address on the iPad
- Verify the required Wi-Fi certificate is installed in the iPad's trust store (Correct answer)
- Reset network settings immediately
- Downgrade to WPA2 on the network
Correct answer: Verify the required Wi-Fi certificate is installed in the iPad's trust store
Enterprise Wi-Fi networks typically require a trusted certificate installed on the device; missing or expired certs are a common cause of connection failures.
