IBM PureFlex Technical Expert V1 Sample Questions:

1. Exhibit:

The technical expert is designing a solution to replace the existing server environment. What configuration will most likely be successful in a highly competitive bid scenario?

A) Flex System using existing XIV and Brocade SAN
B) Flex System with existing XIV externally virtualized by Storwize V7000
C) PureFlex Enterprise with existing XIV externally virtualized by Flex System V7000
D) PureFlex Express with Storwize V7000 used to virtualize the XIV

2. A client has recently installed a Storwize V7000 storage system which they plan to connect to an IBM Flex solution.
However, they are experiencing some performance concerns with the existing installed storage and this is becoming a barrier to the solution sale.
The technical expert is provided with the following information and asked to suggest a possible cause and a solution while on site at the meeting.
Storage:
-Client is an ISP and offers "storage tiers of service" to their clients -Storwize V7000 with several disk expansion trays attached -Mixture of 200 GB SSD, 600 GB 10k rpm SAS drives and 2 TB NL-SAS drives installed -SSD and SAS drives in a single pool; Easy Tier enabled -NL-SAS drives in separate disk pool -Hosts are VMware Virtual machines.. (no applications mentioned) -Latency is high when viewed from the Storwize V7000 onboard performance monitor -Performance Monitor, STAT and Mon traces are provided in the exhibit




IBM 000-784 Exam
What course of action should the technical expert suggest given this initial information?

A) The current Easy Tier solution does not have enough SSD capacity; add SSD drives as advised by the STAT tool
B) Disk contention problems on one or both disk pools
C) Node Canisters latency figures indicate they are faulty and must be replaced
D) Enable Easy Tier on the NL-SAS disk pool to reduce latency

3. The client has three independent redundant SAN fabrics: One for development, one for validation and one for production. The client will use a chassis with x240 nodes to connect these SAN fabrics. What is the best solution for the client?

A) Use one CN4054 adapter, LOM, and four CN4093 switches with FoD enhancements throughout
B) Use two CN4054 adapters and two EN4093 switches, each with two FoD enhancements
C) Use two CN4058 adapters and two CN4093 switches, each with two FoD enhancements
D) Use two CN4058 adapters and four EN4093 switches, each with one FoD enhancement

4. 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 networking defaults should work well for the Ethernet connectivity but the Fibre Channel SAN connectivity must becarefully planned to ensure interoperability
C) The PureFlex system could be inoperable and require potentially expensive last-minute upgrades to get it operational
D) The PureFlex system will work, but performance may be inadequate without potentially expensive upgrades

5. On a PureFlex system, how can an FSM be recovered if the management software is inoperable because of misconfiguration or corruption, but the management node hardware is operational and the hard drives have not failed?

A) Boot while pressing F12 and select the recovery partition as the boot device, then run a full system recovery
B) Call smcli restore from the FSM CLI to restore the FSM
C) Connect to the Internet, download a new FSM image and install it over the IMM connection to the FSM
D) Call IBM Support and request a replacement of the FSM ITE
