IBM C4040-250 Online Questions & Answers

• Question 41:

  A customer asks why they might be interested in open source developed software. Which statement accurately describes the benefit?

  A. Open Source provides binary compatibility applications with AIX.
  B. Open Source projects share the same terms and conditions.
  C. Open Source uses the community development model.
  D. Open Source code is free of security issues.
  C. Open Source uses the community development model.

  ---

  Explanation: Open source software is a community driven effort that uses expertise of various individuals and get evolved in to a robust and secure environment safe for applications and usage.

• Question 42:

  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?

  A. POWER8 requires fewer cores to run the same workload.
  B. POWER8 Active Memory Expansion reduces the cost of memory.
  C. POWER8 cores exploit SMT6.
  D. POWER8 hardware and software maintenance costs are lower.
  A. POWER8 requires fewer cores to run the same workload.

  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 48:

  In addition to one System Node, what is (are) the minimum E880 hardware feature(s)?

  A. One System Control Unit and two I/O drawers
  B. One System Control Unit
  C. One I/O drawer r
  D. Two I/O drawers and one disk expansion drawer

  The IBM Power System E880 with POWER8 system node uses 8-core symmetric multiprocessing (SMP) processor chips with 512 KB of L2 and 8 MB of L3 cache per core, DDR3 CDIMM memory, dual memory controllers, and an industry-

  standard Gen3 PCIe I/O bus designed to use 32 lanes organized in two sets of x16. The peak memory and I/O bandwidths per system node have increased over 300% compared to POWER7+TM servers. The two primary system building

  blocks are one system control unit and one or more system nodes. Additional I/O support is provided with a 19-inch PCIe Gen3 I/O expansion drawer and an EXP24S SFF Gen2 expansion drawer. The processors, memory, and base I/O are

  packaged within the system nodes. The system nodes are rack based.

  New POWER8 processor single chip modules (SCM) are provided in each system node. Processors are interconnected by two sets of system buses. Each SCM contains two memory controllers per processor module. Four 4.35 GHz 8-core

  SCMs are used in each system node, providing 32 cores (#EPBB). As few as eight cores in the system can be activated or up to 100% of the cores in the system can be activated. Incrementing one core at a time is available through built-in

  capacity on demand (CoD) functions to the full capacity of the system.

  The Power E880 can have up to four system nodes per system. With 32-core nodes, the maximum is a 128-core system. In 2014, up to two system nodes per server are supported or a maximum of 64 cores. The system control unit provides

  redundant system master clocks and redundant system master service processors (FSPs). Additionally, it contains the Operator Panel, the System VPD, and the Base DVD.
