Q53. 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.

Q54. 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.
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.

Q56. 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. More supported analytic solutions providing more choices
B. Higher performance and faster response times
C. Greater storage capacity with encrypted data.
D. Stronger encryption capabilities and proprietary analytics algorithms
Answer: B
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.
Q57. An existing customer wants to mitigate the risk of replacing their HP system running an Oracle database with IBM Power Systems.
Which resource should be reviewed with the customer?
A. IBM Power System’s ranking on the RPE website
B. IBM’s participation in the OpenPOWER Foundation
C. IBM Migration Factory
D. IBM Power Systems Roadmap
Answer: C
Explanation: The IBM Migration Factory works across all industries and sectors. It provides support for all phases of an engagement, including customer presales presentation, RFP response and proposal development. The Migration Factory formed at the end of 2003 following the acquisition of IBM Business Partner Sector7. The Migration Factory offers unique skill sets required for cross-platform work.
