• Question 70:

  A banking customer's TS7740 was unable to replicate the tape backup data to the DR data center via the current grid network. The IBM support engineer had created a PMR with Severity 1 because the tape library is supporting the customer's production environment.

Based on IBM guidelines, why would this problem need to be reduced to Severity 2?

  A. Severity 1 only applies to Tape Faillure
  B. Severity 1 only applies to Network Failure
  C. Severity 1 only applies to Production Failure
  D. Severity 1 problem must be resolved within 6 hours
  C. Severity 1 only applies to Production Failure
