Question 1

An administrator has a Power 720 with 64GB of memory and Active Memory Expansion (AME).

How should this be configured in the LPAR?

A. Enter 10GB as 'desired', enter 1.6 in the Active memory expansion factor field.

B. Enter 10GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.

C. Enter 16GB as 'desired', enter 1.6 in the Active memory expansion factor field.

D. Enter 16GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.

Question 5

A partition that uses an LHEA for network connectivity needs to be moved to another managed system. The administrator has the LHEA configured in an Etherchannel with a virtual Ethernet adapter as the backup adapter. When attempting to perform the migration using the Migration Wizard, it fails. What is necessary for the migration to be successful?

A. The HMC command line interface needs to be used to perform the migration.

B. The destination server does not have an LHEA available for the migration.

C. The migration must be initiated from the opertaing systems of the mobile partition.

D. The LHEA must be removed from the Etherchannel before the migration.

Correct Answer: C

Question 6

A single port on a physical Ethernet adapter (ent0) has failed on a VIO Server. The network devices are as follows:

When using the diagmenu command to deconfigure the physical adapter, an error occurs saying the adapter is in use.
What is the correct sequence to deconfigure the physical adapter?

A. Deconfigure ent3 first, then deconfigure ent0, ent1, ent2.

B. Deconfigure ent3 first, then deconfigure only ent0

C. Deconfigure ent3 first, then deconfigure ent0, ent1

D. Deconfigure ent3 first, then deconfigure ent0, ent2.

Correct Answer: C

Question 7

To prevent frames being dropped as a result of network congestion on high speed links, IBM recommends enabling the use of pause frame on compatible switches and IVE adapters. Which attribute enables pause frames?

A. Flow Control

B. Port Group MCS

C. Jumbo Frames

D. 802.3ad

Correct Answer: A

Question 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. seastat-liststatent10

B. entstat-netent10

C. Ismap-net-devent10

D. netstat -cdlistats ent10

Correct Answer: D

Question 9

An administrator has removed a client LPAR and would like to unmap the virtual Fibre Channel adapter vfchost0 from the physical backing adapter fcs2.
Which of the following commands will achieve this?

A. rmvdev -vtd vfchost0

B. vfcmap -vadapter vfchost0 -fcp

C. vfcumap -vdev vfchost0 -dev fcs2

D. rmdev -dev fcs2

Correct Answer: B

Question 10

When creating a new LPAR, what should be considered when setting the maximum value for memory?

A. On a given system, by default the Hypervisor reserves 2.5GB of the system memory, regardless of the maximum memory allocation for an LPAR.

B. The Hypervisor will reserve a fraction of the maximum memory value for page tables.

C. Where the maximum value exceeds 32GB, the Barrier Synchronization Register value needs to be set appropriately in the LPAR profile.

D. The maximum memory value should be a multiple of the desired memory and the Logical Memory Block (LMB) to ensure minimal Hypervisor memory overhead.

Correct Answer: B

Question 11

What is a major benefit for using LHEA instead of an SEA?

A. 64 MAC addresses

B. Logical port throttling

C. 802.11Q support

D. Reduced networking configuration

Correct Answer: D

Question 12

The wlmstat -@ 2 command has been run from a global environment with the following results:

What action can an administrator take to set limits, so that both server1 and server2 use the same amount of CPU resources?

A. Use the syncwpar -E command to copy the CPU resource allocation from server1 to server2.

B. Use the cpu_deallocate -P command to reduce the CPU resources on server2

C. Use the chsysres command to assign the same CPU attributes to both servers.

D. Use the chwpar -R command to set the CPU attributes for each server.

Correct Answer: D

Question 13

When planning a deployment what should be noted about the Virtual Media Repository when compared to other storage visualization offered by a VIO Server?

A. The repository is vulnerable to VIO Server outage.

B. Items within the repository must be virtualized through an NPIV adapter.
