The correct answer is A. Compress the files to reduce the data size before copying to the tape drive. E. Split the files before copying them to the tape drive. To achieve a consistent file transfer rate when archiving large files to a tape drive, the solutions are to compress the files to reduce data size and split large files into smaller chunks.
Question
A storage administrator experiences a slow file transfer rate when archiving backup files on a tape library drive. The tape drive is connected directly to the Cisco Nexus 7009 switches. The file transfer rate gradually goes down with files that are over 100 GB in size. The requirement is for the file transfer rate to be consistent during the transfer window. Which two solutions meet this requirement? (Choose two.)
Options
- ACompress the files to reduce the data size before copying to the tape drive.
- BIncrease the tape drive disk size to increase the write speed.
- CConnect the tape drive with two 10G interfaces in vPC mode.
- DPerform a file transfer to the tape drive after business hours.
- ESplit the files before copying them to the tape drive.

Why each option
To achieve a consistent file transfer rate when archiving large files to a tape drive, the solutions are to compress the files to reduce data size and split large files into smaller chunks.
Compressing files before transfer significantly reduces the amount of data that needs to be written to the tape, helping to maintain a more consistent transfer rate and prevent buffer underrun issues.
Tape drives use cartridges, not disks; increasing capacity does not directly increase write speed.
Connecting with two 10G interfaces in vPC mode increases bandwidth and redundancy but does not address the underlying issue of inconsistent transfer rates with large files on tape drives.
Performing transfers after business hours only shifts the transfer time, it does not solve the technical problem of inconsistent file transfer rates during the transfer window.
Splitting large files into smaller chunks helps maintain a continuous data stream to the tape drive, preventing buffer underruns and allowing the drive to operate at a steady speed without frequent start-stops.
