A technician is backing up 10 GB of data on a file server to a 250 GB external USB hard drive. After 4 GB has been backed up, the software generates an error that the size of the backup exceeds the file limit. Which file system type is being used?

The situation described indicates that the file backup process encounters a limitation after only 4 GB has been transferred, suggesting that the file system in use has a maximum file size limitation that is being exceeded. The FAT32 file system is known for its restriction on individual file sizes, which is capped at 4 GB. This limitation means that any single file being created or transferred cannot surpass this size, leading to the error observed in the backup process.

In contrast, NTFS supports much larger file sizes, far exceeding 4 GB, and is commonly used for its efficiency and robustness in handling modern storage requirements. The VMFS (VMware File System) is designed specifically for virtual machines, and ZFS is a file system and volume manager that can handle large data volumes and files effectively. Neither NTFS, VMFS, nor ZFS would generate a file size-related error in this scenario, confirming that FAT32 is indeed the file system causing the limitation experienced during the backup.
