• Question 13:

  An existing IBM customer explains they cannot consider POWER8 because they have a small application that requires AIX 5.2. Which of the following capabilities will allow that application to run on a POWER8 server?

  A. Little Endian support will allow AIX 5.2 to run on any POWER8 server.
  B. Versioned Workload Partitions (WPARs) for AIX 7.1 EE can allow workloads dependent on AIX 5.2 to run on POWER8.
  C. Logical Partitions (LPARs) enable different versions of AIX to run simultaneously on one POWER8 system.
  D. AIX binary compatibility allows applications created on earlier releases of AIX to run unchanged and without recompilation on POWER8.
  A. Little Endian support will allow AIX 5.2 to run on any POWER8 server.

  Support for little endian mode in the POWER8 processor enables a new generation of applications. While I plan to devote future blog entries to this topic, let me take a moment to address some basic facts about the technology. First, the traditional POWER operating systems (AIX, and IBM i) are big endian and will continue to run as such on POWER8 and future systems. Second, Linux operating systems over time will be migrating from being big endian to little endian in an organized way that by no means compromises the support cycles for their existing releases. Third, as little endian operating systems come to market, a new little endian application ecosystem will grow. Given that most applications today support one or more little endian operating systems (Windows or x86 Linux) and at least one big endian operating system (Linux on Power, AIX, or z/OS), this ecosystem should grow quickly. Finally, little endian mode on POWER8 is not a magic bullet: compiled x86 Linux applications will still require a recompile at a minimum because the x86 and Power instruction set architectures are still different. With this new support, Power will simplify on step in the porting process for new applications, but to develop the whole ecosystem will take time.

• Question 15:

  The executive summary of a proposal should:

  A. present the TCO of the proposal with financial details.
  B. contrast the Power solution to the competitive offerings.
  C. state an overview of all of the elements of the proposal.
  D. provide the primary business objectives of the RFP.
  C. state an overview of all of the elements of the proposal.

  ---

• Question 16:

  Due to new regulatory requirements, a Power Systems customer must set up a disaster recovery site in a geographical location at least 120 miles (194 km) away from the main site. What is the minimum PowerHA solution that should be proposed?

  A. Enterprise Edition
  B. Standard Edition
  C. Geographical Edition
  D. Express Edition
  A. Enterprise Edition

  ---

  Explanation: The PowerHA SystemMirror for i Enterprise Edition includes all of the capabilities of the Standard Edition and more. The Enterprise Edition package enables you to extend your data center solution across two sites. PowerHA SystemMirror Enterprise Edition includes support for DS8000, SVC, V7000, V5000 and V3700 with either Metro Mirror or Global Mirror and with 7.1 of PowerHA SystemMirror, the Enterprise Edition also includes support for geomirroring asynchronous mode. Geomirroring synchronous mode support is included with the PowerHA SystemMirror Standard Edition.
