Question 1

A sales team needed to complete a PureFlex proposal before they had the opportunity to sort out the details of networking connectivity with the client networking team. Therefore, they did not change the networking defaults from the configuration. What consequences might result from this approach?

A. The PureFlex system networking defaults are well thought out and will work well in most circumstances without changes

B. The PureFlex system will work, but performance may be inadequate without potentially expensive upgrades

C. The PureFlex system networking defaults should work well for the Ethernet connectivity but the Fibre Channel SAN connectivity must becarefully planned to ensure interoperability

D. The PureFlex system could be inoperable and require potentially expensive last-minute upgrades to get it operational

Correct Answer: D

Question 2

A client uses a PureFlex With a Flex System V7000 control enclosure. They want to add more storage capacity to the current system but there is no free bay space in the current class.
What is the recommended solution for this scenario?

A. Add a Storwize V7000 expansion enclosure to the current system

B. Add a Storwize V7000 control enclosure to the current system

C. Add a Flex System V7000 expansion enclosure to the current system using another chassis.

D. Add a Flex System V7000 control enclosure to the current system using another chassis

Correct Answer: A

Question 3

A cost conscious client wants to purchase a two POWER node PureFlex solution. Each node will have 16 cores, two AIX LPARs, and they need four ports of FCoE communications. A critical requirement is there can be no single point of failure. Which solution will meet all the client's requirements?

A. p460

B. p260

C. p24L

D. p270

Correct Answer: A

Question 4

A client is purchasing a PureFlex system. They require that their production data keeps running and they do not want the system to slow down if they have disk failures. The PureFlex will be virtualizing the client's storage behind a Flex System V7000 Storage Node; there are no secondary sites. What should the technical expert recommend?

A. Use volume mirroring between the Flex System V7000 and the external storage for the critical volumes

B. Create a pool of SSD drives so that there won't be any disk failures

C. Have the client purchase a Storwize V7000 to put at a new secondary location so that the data can be replicated

D. Use Snapshots so that the data can be restored in the event of a failure

Correct Answer: A

Question 5

Based on the client requirements, what PureFlex advantages should be emphasized to this client?

A. The PureFlex solution only supports 16Gbps Fibre Channel uplinks thus a Fibre Channel link between datacenters is needed if replicatingto the XIV Gen3 is required.

B. The PureFlex solution does not support FCoE with 1Gbps uplinks. FCoE is only supported when using 10Gbps uplinks thus a Fibre Channellink between datacenters is needed only if replicating to the XIV Gen3 is required.

C. The PureFlex solution supports 1Gbps and 10Gbps uplinks. By using external storage virtualization and remote mirror feature the clientcould implement a high-availability solution using FCoE, with integrated management, while leveraging their existing storage systems.

D. The PureFlex solution supports 1Gbps and 10Gbps uplinks. Using the FSM to virtualize the XIV and remote mirror feature the client couldimplement a high-availability solution using FCoE, with integrated management, while leveraging their existing storage systems.

Correct Answer: C

Question 6

The current phase of their modernization effort is focused on upgrading their servers. Which action best addresses the client's requirement?

A. Propose the x222 Flex nodes because they will provide the most cost effective solution

B. Arrange a visit to the closest IBM Briefing Center so they can see the latest releases of the compute nodes

C. Find out what Cisco, HP, and Dell are bidding and build an IBM Flex solution to match them at lower costs

D. Propose IBM's Flex nodes that support all appropriate connectivity options to connect to the existing storage

Correct Answer: D

Question 7

IBM PureFlex Systems offer a wide range of interconnect options. What network interconnect options are available on VCE Vblock systems?

A. iSCSI and FCoE

B. Ethernet 10GbE and Fibre Channel 16 Gb/s

C. InfiniBand QDR/FDR and iSCSI

D. Virtual Fabric 10 Gb/s and InfiniBand QDR/FDR

Correct Answer: A
