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: B

Correct Answer: C

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.

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: A

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.

Correct Answer: C

The GUI storageconfiguration wizard does not know that this storage is mapped to another SAN Volume Controller/Storwize, it can create unbalanced arrays (when optimize for capacity is chosen) or it can leave some drives unconfigured (if optimize for performance is chosen).

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: 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.

Correct Answer: A

In the output of theComprestimator, the Total Savings is presented as a break-down of thin-provisioning savings and compression savings. This helps in future planning tasks; when the volume stores more data than it does today , thin-provisioning savings get lower, but compression savings are expected to stay the same if new data written to the volume is of the same nature as the data stored in the volume today.
