Title : P5 and PSeries Enterprise Technical Support AIX 5L V5.3


1. 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

2. 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 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

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?
A.8-way logical CPU partition, where each logical CPU has the power of 25% of a logical processor
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
Answer: C

4. A customer has just installed a p5 595 with four uncapped LPARs in a shared processor pool. The system and profile settings are still in their default states. One of the LPARs has an application that is consuming all of the available shared processor resources. Users of this application are complaining about response time. Which of the following changes to the slow LPAR would improve response time?
A.Enable SMT
B.Reduce the weight
C.Renice the process
D.Increase the weight
Answer: D

5. A customer wants to buy a new p5 570 running AIX 5.3. The applications require 4 processors and 8GB of memory. There is a requirement to have a Virtual IO Server. What is the smallest p5 570 that should be sold to this customer?
A.4 processors 8GB of memory
B.5 processors 8GB of memory
C.4 processors 10GB of memory
D.5 processors 10GB of memory
Answer: D
