SK0-004 · Question #199
A technician wants to implement a grandfather-father-son tape rotation policy. Which of the following implements this backup strategy?
The correct answer is A. Assign a different set of tapes for daily, weekly, and monthly backups. The grandfather-father-son (GFS) strategy uses three separate tape sets assigned to daily, weekly, and monthly backup cycles, representing the son, father, and grandfather tiers respectively.

Why each option
The grandfather-father-son (GFS) strategy uses three separate tape sets assigned to daily, weekly, and monthly backup cycles, representing the son, father, and grandfather tiers respectively.
GFS rotation is defined by three distinct tape pools corresponding to daily (son), weekly (father), and monthly (grandfather) backups. Each tier retains progressively older restore points, giving administrators both short-term and long-term recovery options. Assigning separate tape sets per cycle is the direct implementation of this naming convention.
Rotating tapes on a two, four, and eight day cycle describes a numeric interval scheme, not the hierarchical daily-weekly-monthly structure that defines GFS.
Odd-day and even-day rotation is a two-set alternating scheme, which provides no hierarchical tiering and does not match any tier of the GFS model.
Rotating tapes by age and usage via a queue describes an automated media management strategy, not the structured three-tier GFS policy.
