NO.5 A customer with AIX and IBM i based applications is considering a move to open source Linux
applications on x86 systems.
Which benefit should be highlighted for the customer to stay with the Power platform?
A. The customer can recompile the AIX and IBM i applications and continue with Linux on their
existing Power System.
B. The Power system uses Lx86 allowing Linux to run unchanged on Power.
C. The Power Linux system is more powerful and will cost less than the x86 systems, thereby saving
costs.
D. The Power system they are running on can support the existing applications and the new Linux
applications at the same time.
Answer: B

Explanation:
PowerVM Lx86 (Linux only) brings new benefits to customers and application providers who want the
reliability and flexibility of Power Systems in their Linux environment, yet use applications that have
not yet been ported to the platform. IBM PowerVM Lx86 allows most Linux x86 binaries to run
unchanged on POWER systems using translation software that translates x86.

NO.6 A customer needing an analytics solution is comparing POWER8 with x86 servers for their
infrastructure.
What makes Power Systems a better value than the x86solution?
A. Stronger encryption capabilities and proprietary analytics algorithms
B. Greater storage capacity with encrypted data.
C. Higher performance and faster response times
D. More supported analytic solutions providing more choices
Answer: C

Explanation:
X86 solutions cannot provide high performance and faster response times during to their
architecture. Power8 processor is much faster and provide consistent performance throughout the
service lifecycle.

NO.7 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. The IBM POWER8 processor is Purpose Built resulting in premium performance over x86, which
results in lower TCA and TCO.
B. Regardless of the benchmark used, IBM POWER8 has proven to be the fastest performing server
chip in the industry.
C. IBM POWER8 servers deliver a lower TCO with unparalleled system reliability.
D. 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.
Answer: A

NO.8 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. AIX binary compatibility allows applications created on earlier releases of AIX to run unchanged
and without recompilation on POWER8.
C. Versioned Workload Partitions (WPARs) for AIX 7.1 EE can allow workloads dependent on AIX 5.2
to run on POWER8.
D. Logical Partitions (LPARs) enable different versions of AIX to run simultaneously on one POWER8
system.
Answer: A
Explanation:
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.
