C9020-562 Online Practice Questions and Answers

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.

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.

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.

Correct Answer: C

The native Internet Protocol (IP) replication feature enables replication between any SVC/Storwize family

memberrunning code version 7.2 or higher, using the built-in networking

ports of the cluster nodes. Following a recent partnership with IBM, it uses SANslide technology developed

by Bridgeworks Limited of Christchurch, UK. They specialize in products that can bridge storage protocols

and accelerate data transfer over long distances.

Adding this technology at each end of a wide area network (WAN) Transmission Control Protocol/Internet

Protocol (TCP/IP) link significantly improves the usage of the link. It does this by applying patented Artificial

Intelligence (AI) to hide latency normally associated with WANs.

The technology built into the SVC/Storwize code uses TCP/IP latency to its advantage. Rather than wait

for the acknowledgment to come back, it sends more sets of packets across other virtual connections. The

number of virtual connections is controlled by the AI engine.

This improves WAN connection use, which results in a data transfer rate approaching full line speed.

Correct Answer: B

IBM VirtualStorage Center for Storwize provides a lower-cost alternative to Fibre Channel- based

replication that is easily configurable in existing IP infrastructures, eliminating the need for FCIP routers

and dark fibre.

SAN Volume Controller can virtualize IBM andnon-IBM storage (over 170 systems from IBM, EMC, HP,

HDS, Sun, Dell, NetApp, Fujitsu, NEC, Bull)

Correct Answer: A

New functionalities in the Version 7.6 release of SpectrumVirtualize include: HyperSwap GUI support: Current local HyperSwap is functionally complete, but requires complex configuration through the existing command-line interface. This new release of HyperSwap offers a new command-line interface which greatly simplifies the set up process to a handful of commands, and also adds the ability to configure and manage local HyperSwap through the GUI.

Correct Answer: A

Flex System V7000 Storage Node includes IBM System Storage Easy Tier, a function that responds tothe presence of flash 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 SSD MDisks, thus placing such data in a faster tier of storage.

EasyTier eliminates manual intervention when assigning highly active data on volumes to faster responding storage. In this dynamically tiered environment, data movement is seamless to the host application regardless of the storage tier in which the data resides.

Correct Answer: A

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.

Correct Answer: A

IBM Variable Stripe RAID is a patented IBM technology that provides an intra-module RAID stripe on each flash module. With two-dimensional (2D) Flash RAID,system-wide RAID 5 along with Variable Stripe RAID helps reduce downtime and maintain performance, and enables the provisioning of an entire flash module as a spare to be used in another flash module failure.
