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

• Question 51:

  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

  Correct Answer: B

• Question 52:

  What is the minimum of connections that an IBM Storwize node canister should have to a host according to best practices?

  A. 4

  B. 1

  C. 2

  D. 6

  Correct Answer: C

  The system contains a Storwize V7000 storage system. Each Storwize V7000 single processing unit is a node canister, which is also called a node. The two nodes within their canisters make an I/O group that is attached to the SAN fabric.

  Each Storwize V7000 control enclosure requires two Ethernet cables to connect it to an Ethernet switch or hub. One cable connects to port 1 of the left node canister, and the other cable connects to port 1 of the right node canister. A 10/100/1000 Mb Ethernet connection is required for each cable. Both Internet Protocol Version 4 (IPv4) and Internet ProtocolVersion 6 (IPv6) are supported.

  Note: For increased redundancy, an optional second Ethernet connection is supported for each Storwize V7000 node canister.

• Question 53:

  An online shopping website stores large amounts of product data and orders on a multi-tier IBM Storwize storage solution. All data is stored in a pool including Nearline, Enterprise, and SSD storage. Depending on purchases, some products may place a higher demand on the storage.

  How will Easy Tier assist this organization with its data performance?

  A. Promotion of data directly from Nearline to Flash storage

  B. Demotion of data from Nearline to Enterprise storage

  C. Demotion of data from Flash to Nearline storage

  D. Promotion of data from Enterprise to Flash storage

  Correct Answer: D

  Note: IBM Spectrum Virtualize includes IBM Easy Tier, a function that responds to the presence of drives in a storage pool that also contains hard disk drives (HDDs). The system automatically and nondisruptively moves frequently accessed data from HDD MDisks to flash storage MDisks, thus placing such data in a faster tier of storage.

  The system supports these tiers:

  *

  Flash tier

  The flashtier exists when flash MDisks are in the pool. The flash MDisks provide greater performance than

  enterprise or nearline MDisks.

  *

  Enterprise tier

  The enterprise tier exists when enterprise-class MDisks are in the pool.

  *

  Nearline tier

  The nearline tier exists when nearline-class MDisks are used in the pool.

  Note 2: The formal distinction between online, nearline, and offline storage is:

  *

  Online storage is immediately available for I/O.

  *

  Nearline storage is not immediately available, but can be made online quickly without human intervention.

  *

  Offline storage is not immediately available, and requires some human intervention to become online.

• Question 54:

  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

  Correct Answer: A

• Question 55:

  A NetApp customer has been concerned about the fragmentation of its system. The customer is considering moving to an IBM Storwize solution.

  What does the IBM Storwize Family use as the foundational file system for file sharing?

  A. HDFS

  B. SMB

  C. GPFS

  D. NFS

  Correct Answer: C

  Shares and exports can be managed through the GUI or CLI by Storwize V7000 Unified administrative users that have a user role definition that isauthorized 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 56:

  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

  Correct Answer: D

  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 57:

  A customer has a pair of IBM Storwize storage systems installed and plans to implement IP based replication for DR and has asked a technical specialist for guidance on remote-copy port groups.

  The technical specialist explains that remote-copy port groups are unique to IP partnerships and must contain at least one IP address in the local system and one IP address in the remote system.

  What is the maximum number of remote-copy port groups that is supported?

  A. 2

  B. 4

  C. 1

  D. 3

  Correct Answer: D

  Remote-copy port groups are unique to IP partnerships, and are the local and remote IP addresses accessible to each other through an IP partnership. A remote-copy port groupmust contain at least one IP address in the local system and one IP address in the remote system. You must configure ports and assign to them a remote-copy port group number before establishing the IP partnership.

  A remote-copy port group is designatedby a number between 0 and 2 inclusive that identifies a set of IP addresses. These port groups are defined as follows:

  Group 0 ?These ports are not configured for remote copy (supports iSCSI host attachment by default) Group 1 ?Ports that belong to remote-copy port group 1 Group 2 ?Ports that belong to remote-copy port group 2 The system will select one pair of IP addresses within port groups 1 and 2, one address on each system, and will open a remote copy connection between them.
