Question #16
A customer wants to encrypt some of the data implementing a clustered IBM Storwize V7000-524 solution, possibly utilizing an existing model 324 keep costs down.
How should the desired solution be implemented?
How should the desired solution be implemented?
- AIBM Storwize V7000-324s and IBM Storwize V7000-524s cannot be clustered together, so two IBM Storwize V7000-524s with encryption enabled on both should be implemented.
- BCluster the existing IBM Storwize V7000-324 with a new model 324 ensuring IBM Storwize version 7.4 is installed on both systems, as it is needed to enable encryption.
- CCluster the existing IBM Storwize V7000-324 with an IBM Storwize V7000-524, enabling encryption of the RAID arrays/MDisks on the Model 524 enclosures.
- DCluster the existing IBM Storwize V7000-324 with an IBM Storwize V7000-524, enabling encryption on all the enclosures for maximum protection.
Correct Answer:
A
The Model 524 control enclosure supports only the attachment of Model 12F, 24F, and 92F expansion enclosures. Previous generation Storwize V7000 control enclosures (Models 112, 124, 312, and 324) do not support the attachment of Model 12F,24F, and 92F expansion enclosures.

Question #17
A customer wishes to provide a VMware administrator with storage capacity to manage the volume creation. The system only has one storage pool.
How should the customer configure the existing system to limit the capacity provided to the administrator?
How should the customer configure the existing system to limit the capacity provided to the administrator?
- AUse IBM Spectrum Control Base
- BCreate one large volume
- CCreate another storage pool with new storage
- DCreate a child pool
Correct Answer:
D
Before V7.4, the disk space of a storage pool was provided from MDisks, so the capacity of a storage pool depended on the MDisks capacity. Creating or splitting a storage pool is not possible and a user cannot freely make a storage pool with a particular capacity they want. A child pool is a new logical object that is created from a physical storage pool and provides most of the functions that Pools have (for example, volume creation), but the user can specify the capacity of the child pool at creation.
A child pool is an object similar to a storage pool, and can be used interchangeably with a storage pool. It supports volume copy and migration.

Question #18
A customer is planning to purchase a new IBM Storwize V5030 system and is evaluating the host Ethernet connectivity requirements.
What is the standard Ethernet interface connection type capability for iSCSI host support in a base V5030 configuration?
What is the standard Ethernet interface connection type capability for iSCSI host support in a base V5030 configuration?
- A8 Gb connectivity
- B10 Gb connectivity
- C40 Gb connectivity
- D16 Gb connectivity
Correct Answer:
B
All Storwize V5000 second-generation control enclosures include support for 16 Gb FC, 12 Gb SAS, 10 Gb iSCSI/FCoE, and 1 Gb iSCSI for additional I/O connectivity.

Question #19
Comprestimator output shows capacity savings from Real-time Compression and which other factor?
- AThin provisioning
- BData archiving
- CDrive consolidation
- DData deduplication
Correct Answer:
A
In the output of the Comprestimator, the Total Savings is presented as a break-down of thin-provisioning savings and compression savings. This helps in future planning tasks; when the volume stores more data than it does today , thin-provisioning savings get lower, but compression savings are expected to stay the same if new data written to the volume is of the same nature as the data stored in the volume today.

Question #20
A customer wants a better understanding of how storage is being used in the file systems of various servers.
Which IBM Spectrum Control tool gathers these details?
Which IBM Spectrum Control tool gathers these details?
- AStorage Resource Agents
- BSTAT
- CTiered Storage Optimizer
- DCapacity reporting
Correct Answer:
A
Storage Resource agents provide file system and local disk information.
You deploy Storage Resource agents if you want to enable full server monitoring for internal resources, such as controllers, disks, and file systems.
Incorrect Answers:
B: The IBM Storage Tier Advisor Tool (STAT) is not an IBM Spectrum Control tool.
