Power Systems with POWER8 Sales Skills V1

Question No: 61

In a competitive situation, a customer wants to compare virtualization capabilities of POWER8 systems and x86 systems.

Which response describes a competitive advantage of PowerVM compared to VMware?

  1. PowerVM runs in a secure address space while VMware runs in application state

  2. PowerVM can run dual VIO servers to provide higher availability

  3. PowerVMprovide higher system utilization because it is implemented in the processor logic.

  4. PowerVM has the ability to virtualize memory while VMware does not.

Answer: B



Question No: 62

A customer has an application that requires the following:

-> 21 cores

  1. TwoS822s

  2. TwoS814s

  3. TwoS824s

  4. One E870 with two client partitions

Answer: C

  1. CoD memory and cores

  2. CAPI

  3. Redundant power supplies

  4. Redundant FSPs

Answer: C

Explanation: The Redundant power supplies are available for both scale-out and enterprise systems.

Question No: 64

A customer is running a large application on x86 Linux with an Oracle Enterprise database.

Which of the following can be used to financially justify migrating the application to POWER8 and DB2?

  1. POWER8 requires fewer cores to run the same workload.

  2. POWER8 Active Memory Expansion reduces the cost of memory.

  3. POWER8 cores exploit SMT6.

  4. POWER8 hardware and software maintenance costs are lower.

Answer: A Explanation:

Comparing performance, the 740D 3.6ghz 16 core is rated at 197.7 rPerf (SMT4) whereas the S822 3.89ghz 12 core is rated at 220.1 rPerf (SMT4) or 235.6 rPerf (SMT8).

So you can get 11 to 19 percent more performance, more memory, more disk bays and PCIe slots for about 40 percent less cost. Another point to note is that the memory and I/O bandwidth for the POWER8 servers (scale out and enterprise) is significantly higher than all of the previous architectures. And there are additional follow-on savings for software licensing-for our 740D versus S822, we need four fewer cores on the POWER8, which allows for additional savings on software licensing.



Question No: 65

Which resource is used to determine if an adapter can move from the 570 to the S824?

  1. Workload Estimator

  2. Sales Manual

  3. Alinean Tool

  4. Fix Central

Answer: B Explanation:

The sales manual provides details and resource that can help determine if the technican can move an adapter on 570 to IBM S824. The compatibility matrix helps in determining the choice and the transfer of hardware from one model to another.

Question No: 66

A customer offers mobile phone plans via a secure website. They requested a meeting to evaluate what IBM has to offer in terms of a hybrid cloud infrastructure and data analytics solution, which will allow them to increase sales of mobile phone plans.

What solution can be proposed to satisfy the requirements?

  1. S814, PowerVM, PowerHA, Worklite, and IBM Cloud Orchestrator

  2. S824, Cognos. IBM Cloud Orchestrator, PowerSC, and PowerVM

  3. S822, ProtecTIER, Websphere, and IBM Cloud Manager with OpenStack

  4. S822, PowerKVM, PowerHA, and Cloud Toolkit

Answer: B

Explanation: With availability beginning June 10, the new scale-out S Class servers include two systems that run Linux exclusively – the Power Systems S812L and S822L servers. The three additional offerings, the Power Systems S814, S822 and S824 servers, provide clients the choice of running multiple operating systems including Linux, AIX and IBM i. Available in 1 and 2 socket and 2U and 4U configurations, the starting price of the new servers



Question No: 67

When implementing a 40TB NoSQL in-memory database on an x86 platform, a customer needs 24 servers. The same database requirement can be satisfied on POWER with a CAPI connected FlashSystem 840.

How many Power S822L(s) is (are) needed?

  1. 8

  2. 16

  3. 24

  4. 1

Answer: D

Question No: 68

A customer is evaluating infrastructure options in order to deploy IBM DB2 BLU. What is a benefit of running DB2 BLU on POWER8?

  1. It exploits large caches and memory bandwidth, delivering better performance

  2. It takes full advantage of 16 threads per core, delivering better performance.

  3. It can be managed with PowerVP to simplify deployment of new images.

  4. It minimizes the number of support contracts that the customer needs.

Answer: A Explanation:

Moving data from memory to disk and back again impacts query performance. But if data stays in memory, the response time is much faster. DB2 10.5 introduces BLU Acceleration for next generation in-memory computing. BLU Acceleration provides breakthrough performance by delivering instant insight from operational data and historical data. IBM Power Systems, with the new POWER8 processor, provides industry-leading capability to keep high volumes of data in memory because of its large cache sizes and memory bandwidth. Power Systems are designed to optimize analytics performance for big data.

Question No: 69

An application has a high availability requirement and is implemented with two local

partitioned POWER8 servers and one remote partitioned POWER8 server. One local server runs production and replicates data to the backup local server. The backup local server replicates data to backup remote server.

What is the minimum number of HMCs required to support the sites?

  1. 4

  2. 2

  3. 3

  4. 1

Answer: B Explanation:

You need 2 HMCs for backup local server to replicate data to backup remote server. Reference: http://www.redbooks.ibm.com/redpapers/pdfs/redp5102.pdf
