IBM C9020-562 Online Questions & Answers

• Question 11:

  A customer wants to create file shares for its Windows clients. The customer is interested in an IBM Storwize V7000 Unified. Which protocol should the customer use for file-sharing?

  A. SMB
  B. NFS
  C. SNMP
  D. iSCSI
  B. NFS

  ---

  Using the NFS protocol, you can transfer files between computers running Windows and other non-Windows operating systems, suchas Linux or UNIX.

  Note:Shares and exports can be managed through the GUI or CLI by Storwize V7000 Unified administrative users that have a user role definition that is authorized to perform share and export management functions.

  A share or export results from making a disk space accessible through the protocols specified during its creation. HTTP, SCP, FTP, CIFS and NFS shares and exports can be created, provided that the corresponding protocol is enabled for

  the system. Shares and exports can only be created for data that is stored in the GPFS file system of the Storwize V7000 Unified system. Non-GPFS file system content cannot be shared or exported.

• Question 12:

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

  ---

  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 13:

  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?

  A. Storage Resource Agents
  B. STAT
  C. Tiered Storage Optimizer
  D. Capacity reporting
  A. Storage Resource Agents

  ---

  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.

• Question 14:

  A small customer has an old VNXe with iSCSI and needs a new storage system that is easy to manage. Price is a concern. Which IBM Storwize family product should the technical specialist recommend to the customer?

  A. Storwize V5010
  B. Storwize V5020
  C. Storwize V7000
  D. Storwize V5030
  A. Storwize V5010

• Question 15:

  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
  A. SSIC

  ---

  The IBM System Storage Interoperation Center (SSIC) is used to check for hardware and software compatibility. References:https://www.ibm.com/support/knowledgecenter/STAV45/com.ibm.sonas.doc/sv c_connectingxivtofcswitch.html

• Question 16:

  When using IBM Storwize family, which IBM software provides application consistent point- in-time copies?

  A. IBM Cloud Object Storage
  B. IBM Spectrum Protect Snapshot
  C. IBM Spectrum Protect for Space Management
  D. IBM Spectrum Control Base Edition
  B. IBM Spectrum Protect Snapshot

  ---

  IBM Spectrum Protect Snapshot (formerly known as IBM Tivoli FlashCopy Manager) uses advanced snapshot capabilities of disk subsystems to create application, database, and VM-aware point-in-time snapshots.

• Question 17:

  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
  B. More appropriate for lower bandwidth intersite links

  ---

  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 18:

  The IBM Storwize V5020 generates a heat file to input into which product to analyze the benefit of Easy Tier?

  A. Storage Tier Optimizer
  B. IBM Spectrum Control Advanced
  C. Disk Magic
  D. IBM Storage Tier Advisory Tool
  D. IBM Storage Tier Advisory Tool

  ---

  The IBM Storage Tier Advisor Tool is a Windows console application that analyzes heat data files produced by Easy Tier and produces a graphical display of the amount of "hot" data per volume and predictions of how additional Solid State Drive (SSD) capacity, Enterprise Drive and Nearline Drive could benefit performance for the system and by storage pool.

• Question 19:

  A company currently has EMC VNX systems at both production and DR sites, with asynchronous replication between the sites. The company desperately needs to refresh the storage at its production site because of performance and capacity needs, as well as high maintenance costs. The VNX at the DR site is newer and still under lease. They don't have the budget to replace both systems.

  How could the IBM Storwize Family solve the problem?

  A. Replace production system and use host-based replication to DR site
  B. Replace production system and externally virtualize DR system
  C. Externally virtualize production system and use Real-time Compression
  D. Externally virtualize both production and DR systems
  B. Replace production system and externally virtualize DR system

• Question 20:

  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
  A. FlashCopy

  ---

  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.
