• Question 42:

  The users within a department require a shared folder on their Windows desktop.

  Which protocol accomplishes this requirement?

  A. GPFS

  B. CIFS

  C. NFS

  D. HTTPS

  Correct Answer: B

  You can connect to a CIFS share using a CIFS client, such as Microsoft Windows.

  The Common Internet File System (CIFS) is the standard way that computer users share files across corporateintranets and the Internet. An enhanced version of the Microsoft open, cross-platform Server Message Block (SMB) protocol, CIFS is a native file-sharing protocol in Windows.

• Question 43:

  A customer wants to clone a database for use as a test environment.

  What feature of IBM Spectrum Control Advanced Edition enables the point-in-time clone to be application consistent?

  A. IBM Copy Services Manager

  B. FlashCopy

  C. IBM Spectrum Protect Snapshot

  D. Volume Mirroring

  Correct Answer: C

  The IBM Spectrum Control Advanced Edition licensed program includes application-aware, snapshot-based protection that is offered by IBM Spectrum Protect Snapshot (formerly known as IBM Tivoli Storage FlashCopy Manager).

• Question 44:

  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?

  A. Use IBM Spectrum Control Base

  B. Create one large volume

  C. Create another storage pool with new storage

  D. Create 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 interchangeablywith a storage pool. It supports volume copy and migration.

• Question 45:

  A state government education system is implementing a cloud solution for schools to plan and score standardized testing. The client needs a solution that supports file and block data for its environment.

  Which IBM Storwize product should the IT architect recommend to maximize storage space using compression?

  A. IBM Storwize V5020

  B. IBM SAN Volume Controller

  C. IBM Storwize V7000 Unified

  D. IBM Storwize V9000

  Correct Answer: C

  Storwize V7000 is designed for all-flash or hybrid storage, while Storwize V7000 Unified isdesigned for block and file needs.

  When you choose Storwize V7000 Unified and Storwize V7000, you gain the most advanced storage technologies to unlock the business value of your stored data, including virtualization and IBM Real-time Compression.

• Question 46:

  What must be configured and installed to use VMware virtual volumes (vVols) with IBM Storwize solutions?

  A. IBM Spectrum Control Base Edition and the correct host type set on the Storwize

  B. IBM Spectrum Virtualize and a vCenter plug in onthe Storwize

  C. IBM Spectrum Control Base Edition and child pools on the Storwize

  D. IBM Spectrum Control Standard Edition and a plug in on the Storwize

  Correct Answer: A

  Three core software components are needed for a successful implementation of VVols. The minimum code level required for each component is provided in the following list:

  *

  IBM Spectrum Control Base Edition (SCB) version 2.2.1 (or higher)

  *

  Compatible storage system running IBM Spectrum Virtualize version 7.6.0 (or higher

  *

  VMware vSphere 6.0 (or higher):

  ?VMware ESXi version 6.0

  ?VMware vCenter Server 6.0 or vCenter Server Appliance (vCSA) 6.0 (vSphere Web Client 6.0)

  )

  We use the term VVols-enabled host to describe a host that meets the following requirements:

  *

  VMware ESXi (ESXi) version 6.0 or later installed.

  *

  Registered with the storage system with host type set to VVol. Note that in the CLI, the VVol host type is referred to as adminlun.

• Question 47:

  Where is the master encryption key supplied for an IBM Storwize V7000 at power on?

  A. SKLM

  B. SAS controller

  C. USB stick

  D. Quorum disk

  Correct Answer: C

  The master keys are stored on USB sticks at the time of array creation. This encryption support means drives themselves can be protect from malicious removal - and if drives fail and need to be replaced you can be surethat nobody can read the data from the failed drives.

• Question 48:

  A customer has two IBM Storwize V5010 systems installed at two locations and is considering IP data replication between the two sites. The IP link between locations is a shared resource and is not scalable.

  Why would Global Mirror with Change Volumes be a beneficial solution for this customer?

  A. Host writes are directly replicated

  B. More appropriate for lower bandwidth intersite links

  C. Smaller Recovery Point Objective

  D. Utilizes Enhanced Stretched Cluster

  Correct Answer: B

  Global Mirror withChange Volumes may be appropriate when bandwidth is an issue, although if bandwidth cannot support the replication, the cycling period may need to be adjusted from seconds up to 24 hours.

• Question 49:

  A customer is looking to enhance its existing environment with the addition of an IBM Storwize V7000. The customer currently has an EMC VNX and wants to better utilize this storage.

  Which two IBM Storwize features must be licensed to address the customer's needs? (Choose two.)

  A. Thin provisioning

  B. Tieredstorage optimizer

  C. Replication

  D. Real-time Compression

  E. External virtualization

  Correct Answer: AB

  A: Thin Provisioning (Oversubscribing)

  Thin LUNs are supported. Care must be taken for the LUNs not to become over allocated or SVC will take

  the MDisk and itsMDiskgroup offline, until corrected.

  B: EMC VNX LUN configuration

  The storage is provisioned from the VNX as LUNs, that appear as managed disks (Mdisks) on the SVC, which can use them to create storage pools (MDiskgroups) to provision SVC volumes (VDisks) for use by hosts or for use with tiering.

• Question 50:

  Which IBM Storwize product allows for scalability up to a maximum of 20 expansion enclosures with a single control enclosure?

  B. IBM Storwize V3700

  C. IBM Storwize V5020

  D. IBM Storwize V5010

  Correct Answer: A

  V5030: Standard expansion enclosures: up to 20 standard expansion enclosures per controller. High-density expansion enclosures: up to 8 high-density expansion enclosures per controller.
