1. 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
2.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
3. 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
4. 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
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
6. 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
7. 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
8. A customer has restored their mksysb. They notice that the external
volume groups cannot be seen. What should be done to access the volume
groups?
A.Run importvg command
B.Run synclvodm command
C.Recreate volume groups
D.Update /etc/filesystems
Answer: A
