SG0-001 · Question #480
Which of the following is a term used to describe the access type used to populate data on a tape drive?
The correct answer is A. Block level. Data is typically populated onto a tape drive using block-level access, allowing backup software to efficiently write and manage data segments.

Why each option
Data is typically populated onto a tape drive using block-level access, allowing backup software to efficiently write and manage data segments.
Tape drives, particularly in backup and archival scenarios, operate at the block level for data access. Backup software reads data in fixed-size blocks from the source system and writes these blocks sequentially to the tape, which allows for efficient streaming performance and easier restoration of various file systems.
WORM (Write Once Read Many) describes a characteristic of certain storage media or configurations that prevents data modification, not an access type for populating data.
'Tape object level' is not a standard or commonly recognized term for data access on tape drives; tapes typically handle data in blocks or as part of a file system abstraction.
While tapes store files, the underlying *access type* for populating the raw tape media by the tape drive and backup application is fundamentally at the block level, which is a more granular and direct interaction than file level.
