IBM Storwize Family Technical Solutions V4

Question No: 1

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?

  1. Network Information Service (NIS)

  2. Kerberos

  3. Services for UNIX (SFU)

  4. POSIX

Answer: B Explanation: 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 No: 3

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

  1. Storage Tier Optimizer

  2. IBM Spectrum Control Advanced

  3. Disk Magic

  4. IBM Storage Tier Advisory Tool

Answer: D Explanation:

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 quot;hotquot; 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 No: 4

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

  1. 4

  2. 1

  3. 2

  4. 6

Answer: C Explanation:

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 No: 5

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?

  1. IBM Storwize V5020

  2. IBM SAN Volume Controller

  3. IBM Storwize V7000 Unified

  4. IBM Storwize V9000

Answer: C Explanation:

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 No: 6

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?

  1. IBM Copy Services Manager

  2. FlashCopy

  3. IBM Spectrum Protect Snapshot

  4. Volume Mirroring

Answer: C Explanation:

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 No: 7

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

  1. IBM Storwize V5030

  2. IBM Storwize V3700

  3. IBM Storwize V5020

  4. IBM Storwize V5010

Answer: A Explanation:

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.

Question No: 8

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

  1. SKLM

  2. SAS controller

  3. USB stick

  4. Quorum disk

Answer: C Explanation:

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 No: 9

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

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

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

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

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

Answer: A Explanation:

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.
