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

1. An LPAR is configured using Virtual IO. It has two Virtual SCSI adapters, connecting it to two VIO servers.
The disks presented over Virtual SCSI are available across both Virtual SCSI adapters (2 paths).
Assuming 20 disks are required, what is the maximum recommended queue depth to maximize performance?

A) 22
B) 20
C) 512
D) 510

2. A dedicated LPAR has two dedicated Fibre Channel HBAs assigned to it.
In order to reduce the amount of hardware, the LPAR will be migrated to a currently
running VIO server.
The administrator collects some server performance from the VIO server and notices that the I/O peaks at 5.5Gbits and runs at an average of 4Gbits per second.
The VIO Server runs two dual port 8Gbit FCS cards, so the load is not affected by other LPARS on the VIO Server.
Which of the following is the most cost-efficient configuration for the VIO client?

A) Assign one of the ports in the 8Gbit Fibre Channel HBA, using NPIV directly to the new client partition.
B) Dedicate two new Fibre Channel HBAs to the VIO Server and use them to exclusively host the vSCSI disks for the new client partition.
C) Assign vSCSI disk for the new client LPAR through prioritized channels.
D) Install SDDPCM drivers onto the VIO Server, set up the client LPAR and run the following command: "datapath priorities vhostX fscsi0 fscsi1 fscsi2 fscsi3".

3. Which of the following is required to support AME?

A) Virtual I/O Server
B) AIX LPARs
C) A maximum of 4GB of RAM per LPAR
D) On-demand memory feature enabled

4. Which of the following statements regarding the implementation of Multiple Shared Processor Pools (MSPPs) is correct?

A) MSPPs allow for both IBM and third party applications to be licensed for a subset of physical processors.
B) MSPPs allow the restriction of transferring available processor cycles from one set of LPARs to another.
C) MSPPs allow for physical sets of processors to be reserved for specific sets of LPARs.
D) MSPPs allow processor capacity consumption to be restricted to a set of LPARs.

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