    What SME record types are required to analyze a potential customer tape workload using Batch Magic?

    A. SMF Type 14, 16 and 21

    B. SMF Type 15, 21 and 94

    C. SMF Type 14, 15 and 21

    D. SMF Type 14, 15 and 94

  • Question 52:

    On a TS3500 Tape Library, what is the minimum number of cartridge cells that can be configured in an L23 frame?

    B. 58

    C. 117

    D. 248

  • Question 53:

    What is the key advantage of the IBM TS7720 over the EMO DLm?

    A. Larger maximum capacity

    B. Virtual drive scalability up to 256

    C. Supports bi-directional replication in a grid

    D. Deduplication which does not use hashing algorithms

  • Question 54:

    As viewed from the front of the library, which frame can be configured as a service bay on the right side of the TS3500 High Availability Tape Library?

    A. 3584-S24 frame

    B. 3584-Lx3 frame

    C. 3584-SC1 frame

    D. 3584-HA 1 frame

  • Question 55:

    Which activity is a customer responsibility during setup of a TS7700 Virtualization Engine?

    A. Initializing logical volumes

    B. Defining East Ready categories

    C. Formatting the tape volume cache

    D. Entering the library sequence number

  • Question 56:

    In a TS7740 two-way grid Cluster 0 is the production site and Cluster I is the remote DR site. The scratch volume category for the production site is 0012 and DR site's scratch volume category is 0022. Before a DR test is started, several DR system updates must be in place to protect the production scratch volumes from being allocated during the test. Assuming Selective Write Protect is enabled, which of the following is one step that must be taken?

    A. Update the DR TCDB volume entries to change the production volumes from 0012 to 0022

    B. Update the DR system's DEVSUPxx parmlib member to use a unique scratch volume category

    C. Disconnect the grid link connections to ensure production volumes are not updated in the remote cluster during the DR test

    D. Run the Return To Scratch process from the DR system to ensure the production and DR system volumes are in sync and protected during a DR test

  • Question 57:

    A customer is in the process of installing a two node TS7740 grid with a single production site. The second site used for DR is 50 km away. They want to set all logical volumes to have a size of 6 GB. What is a possible effect on the customer's tape workload?

    A. It may increase the recall time for logical volumes

    B. It may increase the amount of data stored on stacked volumes

    C. It may increase the mount time for fast ready scratch volumes

    D. It may increase the amount of data stored in the tape volume cache

  • Question 58:

    A newly installed TS7720 Virtualization Engine has recently been integrated into a three-way grid. The logical volumes created in the other two systems are not properly being replicated to the new system. All local IBM and customer support resources have been exhausted in trying to determine the cause with no resolution in sight. What should be the next step to try to resolve the issue via IBM?

    A. Contact local PSR to escalate

    B. Contact the local SSR to escalate

    C. Contact the sales representative to escalate

    D. Contact the local software provider to escalate

  • Question 59:

    On a TS3500 Tape Library, how many cartridge cells are available in a D23 frame with twelve TS1140 drives installed?

    A. 58

    B. 117

    C. 248

    D. 360

  • Question 60:

    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. Six hours after the PMR was created, IBM Level 2 support requested to change the Severity Level to 2, even though the problem had not been resolved. 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
