Correct Answer: A

QUESTION NO: 4
An administrator is designing a new system for their existing batch environment. The current system is a POWER5 570 with 16 cores and 128GB of RAM with a single LPAR running AIX 5.3. It takes 12 hours to run their large batch job which is heavily CPU bound on 4 the available CPUs. The new system will be a Power 770 with 16 cores, 128GB of RAM and the LPAR will run AIX 6.1.What should be done to maximize the batch performance?

A. Disable Simultaneous Multi-threading B. Disable Multiple Shared Processor Pools C. Activate TurboCore mode during batch processing D. Set the processor compatibility mode to POWER7

Correct Answer: A

QUESTION NO: 5
An administrator is planning to configure two new Power Systems servers for Live Partition Mobility (LPM). Each server will be connected to a separate HMC. What is required to achieve this in addition to those requirements needed for LPM with a common HMC?

A. A common IP network between all VIO partitions RMC key exchange between both HMCs and all VIO partitions B. A common IP network between both HMCs SSH key exchange between both HMCs C. An RMC connection between each VIO partition SSL key exchange between each VIO partition and all FSPs D. An RMC connection between both HMCs SSH key exchange between all HMCs and FSPs

Correct Answer: B

QUESTION NO: 6
A second virtual disk has been added to a SuSE Linux LPAR on the existing vhost0 adapter. What must be done for this disk to be recognized on the Linux LPAR?

A. /bin/kpartx -a -v /dev/sdb B. /usr/bin/rescan-scsi-bus C. /usr/bin/cfgmgr D. echo "- - -" > /sys/class/scsi_host/host0/scan

Correct Answer: D

QUESTION NO: 7
An administrator would like to perform a Live Partition Mobility (LPM) operation between two systems. The source system has been configured with a single VIO Server (VIOS) partition and the destination system has been configured with dual VIO server partitions. What must be considered when planning for LPM?

A. Access to all the disk data must be completely provided by at least one of the destination VIO Server partitions. B. A second VIO Server partition must be configured on the source system to allow for LPM. C. Device-level virtualization provided by the single VIOS of the source system must be matched by both of the dual VIOS on the target system. D. An LPAR must be configured on the target system before the LPM operation is invoked.

Correct Answer: A

QUESTION NO: 8
An administrator has configured a system to provide resilient networking through the use of SEA failover. The administrator wants to know if the SEA for one VIO server, ent10, is the active adapter.
Which of the following commands could the administrator use to determine the status of ent10?

A. entstat-netent10 B. netstat -cdlistats ent10 C. Ismap-net-devent10 D. seastat-liststatent10

Correct Answer: B

QUESTION NO: 9
An administrator is trying to perform Live Partition Mobility (LPM) between physical systems managed by the same HMC. The VIO Servers (VIOS) on each physical system are connected to the same SAN. The client LPARs will use virtual SCSI (vSCSI) disks. The SCSI adapter slot numbers are between 11 and 20.Each client LPAR has a unique name. The network used by the client LPARs use Logical Host Ethernet adapters (LHEA).The PowerVM Enterprise edition is being used. No EtherChannel has been configured. Why are LPM activities failing?

A. Multiple MSP (mover service partitions) were configured. B. The ssh keys have not been exchanged between the two VIO servers. C. The SCSI adapter slot numbers are too high. D. This LHEA configuration is not supported for LPM.

Correct Answer: D

QUESTION NO: 10
What is the maximum number of clients which can be configured to use a single port on a Host Ethernet Adapter?

A. 16 B. 8 C. 2 D. 4

Correct Answer: A

QUESTION NO: 11
An architect is designing a new POWER7 implementation consisting of a VIO Server (VIOS) and 6 AIX partitions.
AIX partitions need to occasionally access a tape drive for restoration and backup of application data and tape access will not be required by more than on partition at any time.
The performance of the solution is not critical and the architect wants to keep the cost to a minimum.
Which of the following configurations will address the architects requirements?

A. Allocate a SAS tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using vSCSI. B. Allocate a FC tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using NPIV. C. Allocate a SCSI tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using vSCSI. D. Allocate a USB tape drive to the VIOS partition.
Virtualize connections from the tape drive to the AIX clients using NPIV

Correct Answer: A

QUESTION NO: 12
An administrator is troubleshooting a network connectivity error on a POWER blade.
Checking netstat, the administrator can see that the relevant adapter is "up and running". A ping test to the default gateway times out.
Checking on another adapter, connected to the same LPAR, ping works as expected.
What needs to be checked?

A. If the CIOv network adapter is installed in the correct slot B. If the MCS value is correctly sized for the number of LHEAs C. If the switch module port for the adapter is enabled and plugged in D. If the mapping between network adapter and switch module port is correct

Correct Answer: B
