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

1. What is required on the Global Environment for Live Application Mobility to function?

A) SSH Key Manager
B) RSCT
C) WPAR Manager Agent
D) WPAR Manager

2. 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) 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".
B) 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.
C) 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.
D) 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.

3. A production application is hosted across two Power 750 Express servers, managed by an HMC. Each machine has 16 cores and 32GB RAM. Four 8GB LPARs are defined across the two systems and only 3 LPARs are active at once. Live Partition Mobility is used to maintain availability when maintenance is required.
A test environment is being built across two Power 550 Express servers.
Each machine has 8 cores and 16GB RAM. Four 4GB LPARs will be defined across the two systems, again only 3 will be active at once. To isolate the test and production environment, the test environment is managed by two IVMs.
Two LPARs have been created on each test server. The administrator initiates a Live Partition Mobility operation to test moving LPARs between the servers.
The migrlpar command fails to migrate the 4th LPAR with the following error:
"The target managed system does not have enough available memory to create the partition."
Because the 4th LPAR was inactive, it was expected that an inactive migration would be successful.
Why would this inactive migration fail on the test environment, but succeed on the production environment?

A) Active Memory Sharing (AMS) or Active Memory Expansion (AME) is required for RAM over commitment.
B) IVM-managed systems reserve RAM allocations, even for inactive LPARs.
C) IVM-managed systems do not support inactive migrations.
D) The target managed system already has the maximum number of partitions.

4. A customer is planning to migrate an existing AIX 7 environment from POWER5 hardware to POWER7. The existing deployment consists of multiple machines, each hosting many LPARs. Due to software licensing constraints, the new environment must maintain the same number of logical CPUs. The pmcycles command reports the following on an LPAR on the POWER5 environment:
$ pmcycles -m CPU 0 runs at 2198 MHz CPU 1 runs at 2198 MHz CPU 2 runs at 2198 MHz CPU 3 runs at 2198 MHz CPU 4 runs at 2198 MHz CPU 5 runs at 2198 MHz CPU 6 runs at 2198 MHz CPU 7 runs at 2198 MHz
How many virtual CPUs should be assigned to the destination LPAR on the POWER7 environment?

A) 1
B) 8
C) 2
D) 4

5. An administrator is creating a WPAR with isolated file system spaces. Before creating the WPAR, what should the administrator do?

A) Add the /wparfilesystem to the global environment
B) Add the IP address of the new WPAR to the /etc/hosts file in the global environment
C) Ensure the bos.wpars fileset is installed on the system.
D) Ensure the target disk for the WPAR is not in use.
