IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 認定 A4040-109 試験問題：

1. When attempting to install a VIO client using NIM, an adminstrator finds that no disks are available for installation. The disks are provided by NPIV through the virtual Fibre Channel adapter as described here:

Which of the following explains why is the administrator unable to see the disks?

A) The virtual fibre channel device has not been assigned to the client.
B) The fibre device drivers are missing from the SPOT.
C) The LUNs have been incorrectly zoned.
D) The HBA on the VIO server is not connected to the SAN.

2. 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) The target managed system already has the maximum number of partitions.
C) IVM-managed systems reserve RAM allocations, even for inactive LPARs.
D) IVM-managed systems do not support inactive migrations.

3. An administrator is attempting to apply a Fix Pack to an VIO server which is not connected to a network.
The administrator loaded the Fix Pack DVD into the drive. The updates command fails with an error stating that the local SAS optical drive is busy.
What must be verified before attempting to use the optical drive?

A) That the optical device is allocated to the VIO LPAR.
B) That the device is mounted with Read/Write permissions.
C) That the appropriate SAS adapter is allocated to the VIO LPAR.
D) That the media repository on the VIO LPAR is forced offline.

4. An architect is looking at the implications of uncapped weights for a new POWER7 system. The system will consist of four uncapped logical partitions with the following weightings:

Assuming all partitions have equal entitlement and virtual processor configurations in the partition profiles, and request additional resources from the shared processor pool over a period of 1000 cycles, how many cycles will be allocated to LPAR B?

A) 150
B) 1000
C) 300
D) 250

5. 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) 4
B) 1
C) 2
D) 8
