Why each option

This question tests knowledge of backup strategies that simultaneously satisfy high security and ease of recovery requirements.

ATake a full backup daily with the previous night's tape taken offsite.Correct

Taking a full backup daily ensures the simplest and fastest recovery because only a single tape is needed to restore all data. Moving the previous night's tape offsite provides high security by protecting data against on-site disasters such as fire or theft. This combination directly addresses both requirements of the policy.

BTake a full backup daily and use six-tape rotation.

A six-tape rotation keeps all tapes on-site, which fails the high-security requirement because no offsite copy protects against physical site loss.

CTake a full backup on Monday and an incremental backup on each of the following weekdays.

Incremental backups require restoring the last full backup plus every subsequent incremental tape in sequence, making recovery significantly more complex and time-consuming.

DTake a full backup on alternate days and keep rotating the tapes.

Taking full backups only on alternate days means a data loss window of up to two days, reducing recovery completeness and failing the easy-recovery standard.

ETake a full backup on Monday and a differential backup on each of the following weekdays. Keep

While differential backups simplify recovery compared to incrementals, the answer as presented is incomplete and does not specify a daily full backup or a consistent offsite rotation policy.

FTake a full backup daily with one tape taken offsite weekly.

Taking a tape offsite only once per week leaves up to six days of backups unprotected against an on-site disaster, which does not meet the high-security requirement.
