  A. 2 Gbps
  B. 4 Gbps
  C. 8 Gbps

• Question 3:

  What copying activity does "Pull Cache Copy Throttling" limit on the TS7740?

  A. the data copied from tape to cache
  B. the data copied from cache onto tape
  C. the data copied into the cache from another TS7740 cluster
  D. the data copied out from the cache into another TS7740 cluster
  C. the data copied into the cache from another TS7740 cluster

• Question 4:

  A customer has installed two TS7700 Virtualization Engines in a grid configuration for disaster recovery. Cluster U is local to the production hosts, and Cluster 1 is located in the remote DR center with no host processors. They want to maximize the probability that recently written logical volumes are in the cache of Cluster 1 in case of a loss of Cluster U, while maintaining copies in both clusters. Which Copy Consistency Point settings are most appropriate to use?

  A. Cluster U = RD. Cluster 1 = RD
  B. Cluster U = RD. Cluster 1 = NR
  C. Cluster U = DR. Cluster 1 = DR
  D. Cluster U = NR, Cluster 1 = RN
  C. Cluster U = DR. Cluster 1 = DR

• Question 5:

  What is limited by Performance Increments in the TS7700?

  A. Host Read only
  B. Host Write only
  C. Host Read and Write
  D. Host Read, Write and Grid Replication
  B. Host Write only

• Question 6:

  A customer is impressed by the cost savings shown in the IBM proposal to consolidate their tape infrastructure replacing Oracle 9840 and 9940 tape drives with TS1140. However they are concerned about replacing their 9840 drives as they have a specific workload which requires fast access to the data. What is the best response to this concern?

  A. the 9840 does not provide fast access so there is no issue
  B. the TS1140 has a faster data rate than the 9840 so it will provide faster access to first byte of data
  C. instead of a specific drive type for the workload, using the IBM Economy Data Cartridge provides the required fast access
  D. the newer drive technology in the TS1140 will fail less frequently than the 9840 so overall provide faster access capability
  C. instead of a specific drive type for the workload, using the IBM Economy Data Cartridge provides the required fast access

• Question 7:

  After a requirements analysis including the use of the Batch Magic tool, it has been determined that a TS7740 four-way grid is the most appropriate solution, with two clusters in each of two sites. The customer wants to have four copies of the data, (one in each cluster), but also to minimize the data sent over the network between the sites. What is the best way to setup the TS7740 Virtualization Engines to achieve this?

  A. Setup cluster families
  B. Set up 400 MB logical volumes
  C. Set up Selective Device Access Control
  D. Set up two two-way grids and write two copies of the data as before
  A. Setup cluster families

• Question 8:

  To install an IBM 3592-007 with attached drives housed in a TS3500 Tape Library, which of the following is required?

  A. TS3500 frame with mountings to install the 3592-007 and its switches
  B. Customer-supplied standard rack using switches in one of the TS3500 frames
  C. IBM 3953 frame with switches installed either in 3953 frame or one of the TS3500 frames
  D. IBM 3952 frame with switches installed either in 3952 frame or one of the TS3500 frames
  D. IBM 3952 frame with switches installed either in 3952 frame or one of the TS3500 frames

• Question 9:

  Which two are types of nodes in the TS7700 Virtualization Engine architecture? (Select two)

  A. hNode
  B. vNode
  C. sNode
  D. pNode
  E. tNode
  A. hNode
  B. vNode

• Question 10:

  A customer has a TS3500 Tape Library with TS1140 Tape Drives, but does not have the High Availability' feature. If the accessory fails, which activity must be performed to resume operations?

  A. Contact IBM support
  B. Re-initialize the Library Manager
  C. Cycle between Pause and Auto mode
  D. Perform a re-inventory of the cartridges in the library
  A. Contact IBM support
