Question 17
Correct Answer: B
The backup job creates a full backup every Sunday and incremental backups every other day. The configuration specifies keeping 14 restore points. On the 16th day at 23:00, the backup chain length is evaluated. The job started on a Friday, and the first full backup was created on the following Sunday. By the next Sunday, there will be one full and six incremental backups. The second full backup will be created on that Sunday. Following this, another six incremental backups will be created, followed by a third full backup on the next Sunday. At this point, there will be a total of two full backups and 12 incremental backups in the repository, keeping the most recent 14 restore points.

because the job starts on Friday and there will be a full taken on Sunday. so you have two backup chains from sunday to the next saturday and the first backups (friday and saturday) will be deleted because there are already 2 backup chains that make 14 restore points
