IBM C4040-250 Online Questions & Answers

• Question 51:

  Why is OpenPOWER strategically important for Power Systems customers?

  A. To support IBM i solutions for hybrid clouds
  B. To help integrate IBM Cloud with OpenStack for private cloud.
  C. To collaborate with companies and develop new Power solutions
  D. To enable community development of AIX and PowerVM.
  A. To support IBM i solutions for hybrid clouds

  ---

  Explanation: The connection between the OpenPower Alliance and IBM iis more indirect than direct, but do not miscalculate the significance of OpenPower, IBM's most critical, most ambitious, and most risky strategic move of the 21st century. Although this is all about scale out Linux, the cloud market, and attacking Intel, the IBM i community should be watching closely. It is a business model shift for the Power brand. From a hardware perspective, this is a trip to another galaxy.

• Question 54:

  Which management function is provided by IBM Cloud Manager with OpenStack?

  A. Resource pooling and dynamic VM placement
  B. Ongoing optimization and VM resilience
  C. Electronic Service Agent for proactive hardware reporting
  D. End-user self-service provisioning and automation
  D. End-user self-service provisioning and automation

  ---

  Explanation: IBM Cloud Manager with OpenStack, together with Platform Resource Scheduler, helps to reduce the total cost of ownership of the cloud by using infrastructure more efficiently, sharing resources between tenants, and

  automating tedious cloud management tasks. By continuously monitoring the cloud and taking actions as necessary to ensure that configurable policy objectives are being achieved, performance and availability remain optimal even as the

  topology of the cloud infrastructure and workloads inevitably change with time.

• Question 55:

  A customer needs to support an HPC cluster, and needs the maximum number of cores in a standard 19 inch rack. The customer can run either AIX or Linux. Which POWER8 server best satisfies the requirement?

  A. S824
  B. S822
  C. S822L
  D. S824L
  B. S822

  ---

  The Power S822 is designed to mount in the 36U 7014-T00 (#0551), the 42U 7014-T42 (#0553), or the IBM 42U Slim Rack (7965-94Y) racks. These racks are built to the 19-inch EIA 310D standard.

• Question 56:

  What are key cost elements that should always be included in a POWER8 proposal?

  A. Rack space and DR
  B. Staffing and energy
  C. Software and hardware D. RAS and financing
  C. Software and hardware D. RAS and financing

  ---

  Of course, you need to include the software and hardware implications of Power8 in the proposal so the customers can understand the performance of Power8 in hardware and software environment.

• Question 57:

  Upon meeting in an elevator, a customer's senior executive asks an IBM sales agent to explain in one sentence why POWER8 systems are superior to x86 solutions. Which statement best represents the Power Systems value proposition?

  A. IBM POWER8 servers deliver a lower TCO with unparalleled system reliability.
  B. x86 technology is reaching chip design limitations and x86 performance has not increased proportionality to the chip core count, which results in higher software costs.
  C. Regardless of the benchmark used, IBM POWER8 has proven to be the fastest performing server chip in the industry.
  D. The IBM POWER8 processor is Purpose Built resulting in premium performance over x86, which results in lower TCA and TCO.
  D. The IBM POWER8 processor is Purpose Built resulting in premium performance over x86, which results in lower TCA and TCO.
