The correct answer is D. Replace the LTO3 drive with a DLT IV tape drive. Load the tape. DLT IV and LTO3 are physically and mechanically incompatible tape formats, so a DLT IV drive must be used to read DLT IV tapes.

Question

A company has recently upgraded all backup hardware and media from DLT IV to LTO3 tapes and tape drives. Several weeks after the upgrade, the development team discovers a corruption in one of the application servers and must restore from one of the DLT IV tapes. Which of the following steps are necessary for the server administrator to use these tapes?

Options

  • AReformat the DLT IV tape in LTO3 format. Load the tape.
  • BInstall the DLT IV driver on the LTO3 drive. Load the tape.
  • CLoad the DLT IV tape into the LTO3 drive.
  • DReplace the LTO3 drive with a DLT IV tape drive. Load the tape.

Why each option

DLT IV and LTO3 are physically and mechanically incompatible tape formats, so a DLT IV drive must be used to read DLT IV tapes.

AReformat the DLT IV tape in LTO3 format. Load the tape.

A DLT IV cartridge is physically incompatible with an LTO3 drive and cannot be inserted into it, so reformatting is not possible.

BInstall the DLT IV driver on the LTO3 drive. Load the tape.

No driver can allow an LTO3 drive to read DLT IV media because the tape cartridges are mechanically different and physically cannot be loaded into the wrong drive type.

CLoad the DLT IV tape into the LTO3 drive.

A DLT IV tape cartridge cannot physically be loaded into an LTO3 drive due to the difference in cartridge shell design and dimensions.

DReplace the LTO3 drive with a DLT IV tape drive. Load the tape.Correct

DLT IV and LTO3 cartridges use different physical dimensions, cartridge shells, and recording technologies, making them entirely incompatible at the hardware level. The only way to restore from a DLT IV tape is to replace or supplement the LTO3 drive with a DLT IV tape drive, as no software or driver can overcome the mechanical incompatibility.
