Storage media and cloud services – UGC NET Question

Statements A, B, C and D accurately describe storage options and redundancy. Hard disks and SSDs provide secondary storage, DVDs can distribute data, cloud storage keeps data on remote servers and redundancy improves availability. Statement E is false because local backups remain advisable even with cloud services, and F is false since cloud storage is inherently network-based. Therefore the correct set of statements is A, B, C and D only.

Option A:
Option A is correct because it includes all true statements about physical and cloud storage while rejecting the idea that backups are unnecessary or that cloud access is offline. It aligns with robust data protection strategies.

Option B:
Option B is incomplete because it omits C and does not mention cloud storage, which is a major modern storage option. A, B and D are true but do not cover all correct statements.

Option C:
Option C is incorrect because it includes E, which discourages local backups, contrary to good practice. Mixing a false statement with true ones makes the combination invalid.

Option D:
Option D is incomplete because it omits B and therefore does not acknowledge optical media as a distribution medium. A, C and D are correct but do not represent the full set of correct statements given.
