IBM PureFlex Technical Expert V1 Sample Questions:

1. A client purchased a Flex System six months ago. They configured the management with local user accounts in the CMMs. They recently purchased the FSM and installed it in the system. After configuring the FSM all local CMM user accounts are disabled, and a new user RECOVER_ID has been created. What is the cause of this behavior?

A) The CMM LDAP Server service is stopped on the FSM
B) The client tried more than 3 times to log on with a false Userid or Password
C) The "centralized management" feature has been activated on the FSM
D) The FSM LDAP Server authenticated against the company LDAP server

2. Exhibit:

To respond to the client's RFP, the IBM technical expert performed a Disk Magic study and initially proposed a solution with a mix of both SSD and SAS drives in a Storwize V7000. The client liked the proposal and wants to utilize flash technology, but asked IBM to re-evaluate its cost. They also expressed their desire to maintain the lowest possible latency for their high transaction database workloads, some of which requires sub-millisecond response times. What should the technical expert recommend to best meet all requirements?

A) Add SSD drives to their existing DS8000 and externally virtualize it
B) Rerun the Disk Magic Study with different assumptions for the Storwize V7000
C) Change RAID levels on the Storwize V7000 from RAID 10 to RAID 5
D) Suggest IBM FlashSystem Storage to meet the client's new requirements

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

4. A client wants to purchase a PureFlex solution. Their solution will require 24 ports per Power node to meet their I/O needs. With cost as a consideration, which node will meet the client requirements?

A) A 24-core p270 node with two each EN4093 and FC5022 switches
B) A 16-core p24L node with two each EN4093 and FC5022 switches
C) A 32-core p460 node with four CN4093 switches
D) A 24-core p270 node with four CN4093 switches

5.
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) Find out what Cisco, HP, and Dell are bidding and build an IBM Flex solution to match them at lower costs
C) Arrange a visit to the closest IBM Briefing Center so they can see the latest releases of the compute nodes
D) Propose IBM's Flex nodes that support all appropriate connectivity options to connect to the existing storage
