SK0-005 Question #107: Real Exam Question with Answer & Explanation

The correct answer is A: Tape drive. Tape drives are sequential access devices that require physically winding the tape to locate data, resulting in significantly longer seek times compared to random-access storage like hard drives or solid-state drives.

Security and disaster recovery

Question

A server administrator is attempting to restore a file from monthly backups. The administrator mentions to a coworker that the backup media has the longest seek time of any of the restore methods. From which of the following types of media is the administrator MOST likely restoring?

Options

ATape drive
BSolid-state drive
CRemovable drive
DHard drive

Explanation

Tape drives are sequential access devices that require physically winding the tape to locate data, resulting in significantly longer seek times compared to random-access storage like hard drives or solid-state drives.

Common mistakes.

B. Solid-state drives (SSDs) have no moving parts and offer extremely fast seek times, making them the fastest option for data access, completely contrary to the scenario.
C. Removable drives are a broad category; while some removable drives might be slower, many are USB hard drives or SSDs, which still offer significantly faster seek times than tape.
D. Hard drives (HDDs) use spinning platters and read/write heads for data access. While they have mechanical seek times, these are orders of magnitude faster than the time it takes to wind a tape to a specific location.
