IBM C4090-454 Online Questions & Answers

• Question 51:

  A customer wants to encrypt data written to tape drives. A competitor offers an encryption solution that encrypts the data before sending to the tape drives for compression. IBM wants to offer IBM TS1140 tape drives using the built-in encryption feature. Which competitive advantage does the IBM solution provide?

  A. The TS1140 offers the most secure encryption method available on the market
  B. The TS1140 encrypts and compresses data at the same time for best throughput
  C. The TS1140 encrypts data before compressing in order to obtain best performance
  D. The TS1140 compresses data before encrypting in order to obtain the best compression ratio
  D. The TS1140 compresses data before encrypting in order to obtain the best compression ratio
