ACSP File System and Storage 5

Question 1

A user wants to share a large video file between a Mac and a Windows 11 PC using an external drive without reformatting. Which file system supports this with files larger than 4 GB?

Accepted Answer

ExFAT

Answer

ExFAT supports files larger than 4 GB and is natively readable and writable on both macOS and Windows without additional drivers.

Question 2

Which macOS utility command verifies and repairs permissions on a volume running macOS Catalina or later?

Accepted Answer

diskutil repairVolume /

Answer

On macOS Catalina and later, `diskutil repairVolume` is used since System Integrity Protection manages system file permissions automatically.

Question 3

When a macOS system volume is mounted as 'read-only' after a failed update, what underlying technology enforces this protection?

Accepted Answer

Signed System Volume (SSV)

Answer

The Signed System Volume (SSV) cryptographically seals the system volume, and macOS mounts it read-only to protect its integrity.

Question 4

A Mac supports up to how many APFS volumes within a single APFS container before performance may be impacted?

Accepted Answer

There is no defined limit; performance depends on available storage

Answer

APFS imposes no hard limit on the number of volumes per container, but all volumes share the same pool of free space and I/O resources.

Question 5

What does the 'noatime' mount option do when applied to an APFS or HFS+ volume on macOS?

Accepted Answer

Prevents access-time timestamps from being updated when files are read

Answer

The `noatime` option stops macOS from writing an updated access-time to disk every time a file is read, reducing unnecessary write operations.
