145 If you back up your network by performing a full backup every Wednesday at 6:00 p.m. and incremental backups in the evening of the other days of the week, how many jobs would be needed to completely restore a computer with a hard drive that failed on a Monday at noon?OneTwoFiveSix

146 How does an autochanger increase the overall storage capacity of a backup solution?By compressing data before it is stored on the mediumBy automatically inserting media into and removing it from a driveBy running a tape drive at half its normal speedBy writing two tracks at once onto a magnetic tape

147 For a complete restore of a computer that failed at noon on Tuesday, how many jobs would be needed if you performed full backups to tape at 6:00 a.m. every Wednesday and Saturday and incremental backups to tape at 6:00 a.m. every other day?OneTwoThreeFour

148 If you back up your network by performing a full backup every Wednesday at 6:00 p.m. and differential backups in the evening on the other six days of the week, how many jobs would be needed to completely restore a computer with a hard drive that failed on a Tuesday at noon?OneTwoSixSeven

149 Why does performing incremental backups to a hard drive, rather than a tape drive, make it possible to restore a server with a single job, rather than multiple jobs?Because hard drives hold more data than tape drivesBecause hard drives can transfer data faster than tape drivesBecause hard drives are random access devices and tape drives are notBecause hard drives use a different block size than tape drives
