IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 Sample Questions:

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

2. An administrator has a requirement to back up a VIO server (VIOS) so that it can be rebuilt in the event of a disaster. Which set of actions will achieve this requirement?

A) Save "Upgrade Data" on the HMC. Backup all non rootvg volume groups using savevg. Run a mksysb of the VIOS with the -U flag.
B) Backup all non rootvg volume groups using savevg. Backup all Storage Pool Information. Run a mksysb of the system.
C) Capture the virtual network tuning to a file using the optimizenet command. Capture all virtual device attributes to a file using the lsattr command. Run a backupios.
D) Backup non rootvg structures using savevgstruct. Capture virtual mappings to a file using viosbr. Run a backupios

3. A customer is planning to purchase a fully populated Power 795. There are 65 applications which need to run and all need an AIX 7 environment. The architect is considering whether to use an LPAR for each application or to use a single large LPAR and have a WPAR for each application.
What must be considered before creating the environment?

A) There is a limit of 64 WPARs in any AIX V7 global environment.
B) An activation key for LPARs with more than 128 processors is required.
C) Multiple IVE adapters are required to support all the partitions.
D) There is a limit of 32 Processors in a WPAR.

4. An administrator wants to add vSCSI adapters to a new client using the existing mapping schema. The slots will be 40/41 on the VIO Server. Given the current properties of the VIO server, what must be done to accomplish this?

A) Change the Maximum virtual adapters to 50 in the VIOS partition profile.
Create the vSCSI adapters on slots 40/41 in the VIOS partition profile and map them to the
new client.
Shutdown and reactivate the VIOS.
B) Change the Maximum virtual adapters to 50 in the VIOS partition profile.
Create the vSCSI adapters on slots 40/41 in the VIOS partition profile and map them as
"Any client partition can connect".
Reboot the VIOS.
C) Use DLPAR to increase the Maximum virtual adapters to 50.
Use DLPAR to create the vSCSI adapters on slots 40/41 and map them as "Any client
partition can connect".
D) Use DLPAR to increase the Maximum virtual adapters to 50.
Use DLPAR to create the vSCSI adapters on slots 40/41 and map them to the new client.

5. An architect is desiging a new virtualized POWER7 system. The system will have a number of AIX and Linux LPARs and will be deployed with a logical memory block size of 16MB.Which of the following could be used to determine the amount of memory used by the Hypervisor?

A) LPAR Validation Tool.
B) System Configurator.
C) Facts and Features Guide.
D) System Planning Tool.
