1. A customer has several AS/400 servers in their IT infrastructure running V5R2 that they wish to consolidate. The customer wants to simplify their environment and install i5/OS on a p5 590 with 16 1.65GHz processors and 20 i5/OS partitions. The customer plans to use the Advanced Power Virtualization to share their storage, processors, and memory. What considerations and limitations should be reviewed with the customer before the purchase?
A. Resources cannot be shared with an i5 partition when it is put on a pSeries. The i5 partition needs its own 9411-100 tower because of IOP. V5R3 OS or later is required. There is a maximum of two partitions in a 590.
B. Resources cannot be shared between partitions when i5/OS is put on a pSeries. The i5 partition needs its own 9411-100 tower because of IOP. i5/OS can be at V5R2 or a V5R3. Currently only one i5 partition is allowed.
C. V5R3 is required for the i5 partitions. Virtual IO Server is not supported for the i5/OS partitions to share storage. Up to 10 i5 partitions per processor are allowed (a maximum of two processors for up to 20 partitions).
D. Processor and memory resources can be shared between AIX 5L, Linux and i5/os partitions. i5/OS needs to be at V5R3, and Virtual IO Server is not supported for the i5/OS partition to share storage. On a 1.65 GHz POWER5 p5 590 there is a maximum of one partition.
Answer: C
2. A customer wants to use Virtual SCSI disks to boot multiple operating systems from the same disk. How will the volumes appear in the Virtual IO Server and how will the logical volumes appear in the partition?
A. The Virtual SCSI disks are defined as logical volumes in the Virtual IO Server. The logical volumes appear as real devices (hdisks) in the client partitions.
B. The Virtual IO adapters are connected to a virtual host bridge. On the Virtual IO Server they are vdisks, on the client partition, the exported disks are visible as virtual disks.
C. The Virtual SCSI disks are represented in the ODM as a bus device whose parent is sysplanar0. Logical volumes will be assigned to the Virtual IO Server and virtual disks, vdisks, in the client partition.
D. The Virtual IO adapters are represented as adapter devices with the virtual host bridge as their parent. On the Virtual IO Server they are vdisks attached to vscsi, on the client partition the exported disks are visible as virtual disks.
Answer: A
3. A customer has purchased a p5 590 with 16 CPUs. To run Simultaneous Multi-Threading (SMT) with a 4-way virtual processor partition with 2.0 processing units of entitlement, how many logical CPUs will be allocated?

B. 4-way logical CPU partition, where each logical CPU has the power of 50% of a physical processor
C. 8-way logical CPU partition, where each logical CPU has the power of 25% of a physical processor
D. 16-way logical CPU partition, where each logical CPU has the power of 25% of a physical processor

D. Update /etc/filesystems
Answer: A
7. A customer is purchasing a p5 595 as part of a large server consolidation. They are planning on using micropartitioning and Virtual IO to consolidate small machines. They used the rPerf numbers for AIX 5.3 to size their solutions. They discovered that their application is not yet certified on AIX 5.3, so they will have to use AIX 5.2. What changes should be made to their configuration?
A. Increase memory
B. Add more adapters
C. Increase both processors and adapters
D. Increase the number of processors by 20 - 30%
Answer: C
8. A customer is moving their application to a p5 590 and at the same time moving to a new version of the application. The customer knows only about the resource requirements of the old version. Which of the following is the best method to migrate their application to POWER5?
A. Add CPU and memory COD so they have room to grow if required
B. Make the server configuration twice as large as the current requirement
C. Configure the server for the current capacity requirements
D. Make the server configuration a little larger than the current capacity requirements
Answer: A
9. A large customer is consolidating their pSeries systems onto a p5 590. They will have a requirement for a single device (disk, lun) to have multiple paths through different adapters in a single LPAR. The primary applications were written for AIX 5.2. Which of the following would be the recommended solution to satisfy this requirement?
A. Assign the adapters to a Virtual IO partition
B. Use the MPIO function included in AIX 5.2
C. Migrate the application to AIX 5.3 and use the MPIO function
D. Set up two Virtual IO partitions and attach both partitions to the device
Answer: B
10. A customer has a requirement for an LPAR in their p5 595 to run SUSE Linux. They also require an adapter that is not currently supported in Linux. Which of the following would be the best solution to recommend?
