IBM IBM Certified Specialist - Storwize Family Technical Solutions V4 C9020-562 Questions & Answers

• Question 11:

  A customer is planning to implement a new IBM Storwize V5030 solution and is evaluating the requirements for implementing disaster recovery with HyperSwap.

  Which HyperSwap configuration requirement needs to be part of installation?

  A. Both I/O groups and managed disks are at the same site.

  B. Configuration with standard topology with all controlenclosures are at the same site.

  C. Configure volume mirror relationship with a controller from each I/O group at different sites.

  D. Each I/O group and its managed disks are at different sites.

  Correct Answer: D

  HyperSwap volumes, where copies of a single volume are in different storage pools that are on different sites. The volume is cached in two I/O groups that are on different sites. These volumes can only be created on Storwize V5030 systems when the system topology is HyperSwap.

• Question 12:

  A customer wants to create an IBM SVC Enhanced Stretch Cluster between two data centers.

  Which license is required to create this configuration?

  A. Spectrum Control

  B. Spectrum Virtualize

  C. FlashCopy

  D. Metro Mirror

  Correct Answer: B

  The Enhanced Stretched Cluster configuration provides a continuous availability platform, whereby hostaccess is maintained during the loss of any single failure domain. This availability is accomplished through the inherent active/active architecture of IBM Spectrum Virtualize and SAN Volume Controller along with the use of volume mirroring.

• Question 14:

  Which product should be included as part of an IBM Storwize Family solution for a customer who desires to simplify and automate capacity management?

  A. IBM Spectrum Control

  B. Easy Tier

  C. IBM Spectrum Archive

  D. Tiered Storage Optimizer

  Correct Answer: A

  Spectrum Control provides analytics-driven storage management and efficient infrastructure management for virtualized, cloud, and software-defined storage to simplify and automate storage provisioning, capacity management, availability monitoring, and reporting.

  IBM Spectrum Control communicates with Storwize V7000 storage systems through a native interface.

  Use IBM Spectrum Control to monitor Storwize V7000 systems, including discovery, data collection (probes), performance monitoring, trending, storage optimization, and provisioning. IBM Spectrum Control reports and topology views also provide information about the tier, tier capacity, and tier free capacity for Storwize V7000.

• Question 15:

  Which network authentication protocol is supported on the IBM Storwize V7000 Unified storage system, is used for client/server applications, and provides symmetric key cryptography?

  A. Network Information Service (NIS)

  B. Kerberos

  C. Services for UNIX (SFU)

  D. POSIX

  Correct Answer: B

  Kerberos To provide heterogeneous file sharing for Unix and Windows, the Storwize V7000 Unified system must support authentication methods for Unix and Windows. The Storwize V7000Unified system uses Windows authentication for incoming CIFS connections and Unix authentication for incoming NFS, HTTP, SFTP and SCP connections.

  Kerberos is a network authentication protocol for client/server applications that uses symmetric key cryptography.

  Note: User password in clear text format is never sent over a network; the Kerberos server grants a ticket to the client for a short span of time. This ticket is used while communicating with the server to obtain access to the service, such as a file server. The Windowsbased authentication is based on Kerberos. MIT Kerberos is a free implementation of the Kerberos protocol, which is provided by the Massachusetts Institute of Technology.

• Question 16:

  A data center provides a Cloud Software as a Service environment primarily for websites and online transactions. Each client is allocated a standard 400 GB LUN for storage. The data center wants to reclaim usable capacity and avoid the need to purchase new disks.

  How can this be achieved using IBM Storwize V5020?

  A. Implement IBM Real-Time Compression to the existing LUNs to provide more free space.

  B. Add a Thin-Provisioned copy to a fully allocated LUN, then remove the fully allocated LUN.

  C. Use external storage virtualization to add new LUNs.

  D. Reconfigure internal drives from RAID5 to RAID6.

  Correct Answer: A

  Store up to five times as much active data in the same physical space with IBM Real-time Compression. It is supported by the three StorwizeV5000 hybrid models: IBM Storwize V5030, IBM Storwize V5020 and IBM Storwize V5010.

• Question 17:

  A customer has an Oracle RAC environment that requires high availability and disaster recovery in one solution.

  Which feature of IBM Spectrum Virtualize addresses these needs?

  A. FlashCopy

  B. HyperScale

  C. HyperSwap

  D. Volume Migration

  Correct Answer: A

  IBM Spectrum Protect Snapshot uses the FlashCopy or snapshot function of the storage solutions for database cloning. This method eliminates downtime and minimizes the impact on the production database.

  After you share the FlashCopy repository, configuration and binary files, an Oracle RAC database clone can be created from every node of the Oracle RAC cluster. IBM Spectrum Protect Snapshot can operate on the clone from all RAC nodes, so that a clone created on one RAC node can be inquired, refreshed, or deleted from any other node within the RAC cluster.

• Question 18:

  Which IBM Storwize family member is capable of two-way system clustering?

  A. Storwize V5010

  B. Storwize V3700

  C. Storwize V5020

  D. Storwize V5030

  Correct Answer: D

  Storwize V5030 supports maximum of 760 drives per system and 1,056 drives in two-way cluster.

• Question 19:

  A solution requires access to a file share on the IBM Storwize V7000 Unified via Mac OS X 10.7, RHEL 6.4, and Windows 8.

  Where should the technical specialist determine connection protocol support for this mixed environment?

  A. SSIC

  B. eConfig

  C. Announcement

  D. SalesManual

  Correct Answer: A

  The IBM System Storage Interoperation Center (SSIC) is used to check for hardware and software compatibility.

• Question 20:

  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?

  A. IBM 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.

  B. Cluster 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.

  C. Cluster the existing IBM Storwize V7000-324 with an IBM Storwize V7000-524, enabling encryption of the RAID arrays/MDisks on the Model 524 enclosures.

  D. Cluster 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.
