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

1. 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, ent2.
B) Deconfigure ent3 first, then deconfigure ent0, ent1, ent2.
C) Deconfigure ent3 first, then deconfigure only ent0
D) Deconfigure ent3 first, then deconfigure ent0, ent1

2. An administrator has a Power 720 with 64GB of memory and Active Memory Expansion (AME).
An LPAR has only 10GB of memory available and an application has been sized at 15GB of memory. The administrator runs amepat to determine an efficient expansion factor. Based on the output, an expansion factor of 1.6 has been chosen.
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' and modify/etc/ame.conf with AME_RATIO=1.6.
D) Enter 16GB as 'desired', enter 1.6 in the Active memory expansion factor field.

3. As a result of an acquisition, an administrator is planning to consolidate some single-LPAR POWER6 520 servers onto an existing POWER7 server.
The administrator is attempting to make these 520 systems HMC-managed.
The network connection between the 520 system and an existing operational HMC have been verified and checked. However the POWER6 machines fail to appear on the HMC panels.
What is the most likely resolution for this issue?

A) Upgrade to either PowerVM Standard or Enterprise edition.
B) The POWER6 boxes need to be reset back to factory defaults.
C) Power cycle the physical system.
D) The Flexible Service Processor (FSP) needs to be reset on each POWER6 520.

4. A number of uncapped partitions, which do not use multiple shared processor pools, are requesting additional processor resources. There are not enough resources available to satisfy all the requests. How does the hypervisor determine allocation of the available resources?

A) Each partition would receive a share based on the maximum entitlement of the partition as a fraction of the sum of all the requesting partitions' entitlements.
B) Each partition would receive a share based on weighting value of the partition as a fraction 1000 clock ticks for a millisecond.
C) Each partition would receive a share of the available resource based on the delta between the desired and maximum entitlement.
D) Each partition would receive a share based on the weighting value of the partition as a fraction of the sum of all the requesting partitions weights.

5. While reactivating client LPARs following a scheduled power down, some LPARs have lost visibility to their NPIV-allocated SAN LUNs. On investigation it appears the WWNs have changed on the problem LPARs. What is the most likely cause for the change in WWN?

A) The NPIV adapters on the VIOS LPARs were not tagged as being "required for partition activation."
B) The WWNs will have changed due to the recycle of the Hypervisor. The chsyscfg -r command should be used to recover the previously allocated WWN.
C) The option to randomly assign WWNs for security reasons has been selected.
D) The virtual Fibre Channel client adapters were dynamically allocated to the LPARs before being added to the partition profile.
