NO.1 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.

NO.2 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 Power Linux system is more powerful and will cost less than the x86 systems, thereby saving
costs.
B. The Power system they are running on can support the existing applications and the new Linux
applications at the same time.
C. The Power system uses Lx86 allowing Linux to run unchanged on Power.
D. The customer can recompile the AIX and IBM i applications and continue with Linux on their
existing Power System.

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.3 A client running Oracle databases is considering a Power solution. They want the highest level
of reliability, performance, and support.
Which operating system on Power should be recommended?
A. Red Hat
B. IBMi
C. AIX
D. SUSE
Answer: C

Explanation:
Businesses today need to maximize the return on investment in information technology. Their IT
infrastructure should have the flexibility to quickly adjust to changing business computing
requirements and scale to handle ever expanding workloads-without adding complexity. But just
providing flexibility and performance isn't enough; the IT infrastructure also needs to provide rock-
solid security and near-continuous availability and while managing energy and cooling costs.
These are just some of the reasons why more and more businesses are choosing the AIX operating
system (OS) running on IBM systems designed with Power Architecture@ technology. With its proven
scalability, advanced virtualization, security, manageability and reliability features, the AIX OS is an
excellent choice for building an IT infrastructure. And, AIX is the only operating system that leverages
decades of IBM technology innovation designed to provide the highest level of performance and
reliability of any UNIX operating system.

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.
