ACSP Data Management and Backups 5 — Questions and Answers
Question 1: A technician needs to clone a bootable macOS drive to a new SSD. Which tool is best suited for creating a bootable clone on Apple Silicon Macs?
- Disk Utility Restore function
- Carbon Copy Cloner or SuperDuper (Correct answer)
- Time Machine
- Migration Assistant
Correct answer: Carbon Copy Cloner or SuperDuper
Third-party tools like Carbon Copy Cloner or SuperDuper are designed to create bootable clones and handle APFS-specific structures and Apple Silicon requirements that Disk Utility's Restore may not fully replicate.
Question 2: Which command-line tool is used to manage Time Machine backups, list snapshots, and trigger manual backups from Terminal?
- backupd
- tmutil (Correct answer)
- timemachine
- diskutil backup
Correct answer: tmutil
tmutil is the command-line interface for Time Machine, allowing admins to start/stop backups, list snapshots, and manage backup destinations from Terminal.
Question 3: A user's iCloud Drive is nearly full, causing sync issues. What is the most appropriate first step an ACSP technician should take?
- Delete the iCloud Drive folder on the Mac
- Review storage in System Settings > Apple ID > iCloud and remove unneeded data or upgrade storage (Correct answer)
- Disable iCloud Drive and use a local folder instead
- Reinstall macOS to clear iCloud cache
Correct answer: Review storage in System Settings > Apple ID > iCloud and remove unneeded data or upgrade storage
Checking iCloud storage usage in System Settings allows the technician to identify what is consuming space and advise on removing data or purchasing additional iCloud+ storage.
Question 4: When migrating data from an old Mac to a new Mac using Migration Assistant, which connection method provides the fastest transfer speed?
- Wi-Fi
- Thunderbolt cable (Correct answer)
- USB-A cable
- Ethernet
Correct answer: Thunderbolt cable
A Thunderbolt cable provides the highest bandwidth (up to 40 Gb/s), making it the fastest option for Migration Assistant transfers between two Macs.
Question 5: An organization wants to prevent employees from using external drives for Time Machine backups and restrict backups to an approved network share. Which tool is used to enforce this policy?
- Apple Configurator 2
- Mobile Device Management (MDM) with a Time Machine configuration profile (Correct answer)
- FileVault
- System Integrity Protection (SIP)
Correct answer: Mobile Device Management (MDM) with a Time Machine configuration profile
An MDM server can deploy a Time Machine configuration profile that restricts backup destinations to approved network volumes and disables use of local external drives.
Question 6: What is the purpose of the 'Optimize Mac Storage' option in iCloud Drive settings?
- Compresses local files to save space
- Stores full-resolution files only in iCloud and downloads them on demand, keeping smaller local copies (Correct answer)
- Moves all files to an external drive automatically
- Encrypts local files using FileVault
Correct answer: Stores full-resolution files only in iCloud and downloads them on demand, keeping smaller local copies
Optimize Mac Storage allows macOS to keep only recently accessed files locally in full quality while older files are stored in iCloud and downloaded on demand to free local disk space.
Question 7: A user reports that Time Machine backups have been failing with an error indicating the backup disk needs to be repaired. What should the technician do first?
- Erase and reformat the Time Machine disk, then start a new backup set
- Use Disk Utility to run First Aid on the Time Machine backup disk (Correct answer)
- Delete the Time Machine backup folder and let it recreate
- Replace the disk immediately as it is failing
Correct answer: Use Disk Utility to run First Aid on the Time Machine backup disk
Running First Aid in Disk Utility repairs minor file system errors on the Time Machine disk, which often resolves backup failures without requiring a full erase.
