IBM Assessment: Virtualization Technical Support for IBM i -v1 Sample Questions:

1. A processor upgrade to a new 4-core Power 720 is planned, with processors capped and shared processor pools enabled, using the following configuration:
IBM i: Minimum - 1 .0; Desired - 2.5; Maximum - 2.5
Linux: Minimum - 0.5; Desired - 1.0; Maximum - 1.0
AIX: Minimum - 0.5; Desired - 0.5; Maximum - 1 .0
How many processor entitlements for IBM i are required on the new system?

A) 1
B) 2
C) 3
D) 4

2. A customer is implementing a new POWER7 system that will run along with an older POWER5 system.
A new HMC has been purchased for the POWER7 system.
The older 7310-CR3 HMC for the POWER5 system will remain in service.
The customer wants the older 7310-CR3 provide back up to the new HMC.
What must be done prior to implementing the customer's requirements?

A) Upgrade the POWER5 system firmware to the same fix pack level that the POWER7 system is
running. Upgrade the 7310-CR3 to the latest version of HMC code.
Connect both systems normally to the 7310-CR3
B) Ensurethe POWER7 ESP is running in "Dual Mode"with the"Activated Level"setto supportthe
POWER7 system and the "Deferred Level"set to support the POWER5 system.
Connect the 731 O-CR3 with the "Deferred Level"password.
C) Connect the new HMC to the POWER7 system and to the LAN.
Use the "Transmit Service Information"dialog on the new HMC to update the 7310-CR3 with the
new HMC code and firmware for the FSP.
Update the firmware on the POWER5 system and connect the new HMC.
D) Consult the HMC / Firmware Supported Combinations chart to obtain the proper firmware/HMC
code levelsimplementthe firmware updates on the POWER5 and 7310-CR3 HMC first,
Connectthe 7310-CR3 to the POWER7 system.

3. When attempting to remove a large amount of memory from a partition, the HMC generates an error stating that all the memory requested was not removed.
What can be done to help ensure all the memory gets removed when the request is attempted again?

A) Increase the amount of time allocated for the memory removal operation.
B) Move the memory to an unallocated shared pool in the partition.
C) Change system value QMEMSHRPIRI to *HIGH.
D) Rebootthe HMCto ensure caches are cleared.

4. A POWER7 server is being configured with 1 hosting IBM i partition and 4 client IBM i partitions. All partitions will run IBM i 7.1, TR4. The hosting partition is providing network support to the client partitions and needs both redundancy and best bandwidth.
What connectivity on the host partition will support these requirements?

A) Using two or more physical Ethernet resources configure an aggregated link to the switch and use this for IP address of the host partition.
B) Using two or more physical Ethernet resources configure an aggregated link to the switch and use this for the bridge to the internal vLANs used by the client partitions.
C) Configure two or more Ethernet lines. Use the lines to create redundant bridges to the internal vLANs used by the client partitions.
D) Configure two or more Ethernet lines. Create a Virtual IP address for the host partition. Configure Showler routes to the local network for load balancing.

5. A client IBM i partition is being planned. Dual VIO Servers will each provide 40 SAN disks to the client partition, mirrored in IBM i at the adapter level (see example below).

Considering both the host and client partitions, what is the minimum number of vSCSI adapters required to support this disk configuration?
