IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 Sample Questions:
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. The target managed system already has the maximum number of partitions.
- D. IVM-managed systems do not support inactive migrations.
Certain configurations of Power 770 and Power 780 servers can be ordered with multiple IVE adapters. When designing a configuration to provide improved network availability what fact should be observed as a risk?
- A. The same model of IVE must be ordered for each building block.
- B. An EtherChannel device created from adjacent IVE ports can result in broadcast storms.
- C. 1Gbps and 10Gbps adapters may not be aggregated into a single logical link.
- D. IVE adapters do not support hot-plug operations.
After restoring a mksysb image from a NIM server, an administrator noticed that the SEA interface had not been successfully reconfigured.
Which one of the following could explain this?
- A. The logical device structure must be backed up prior to the backupios operation.
- B. An invalid bosinst.data file was allocated to the VIO Server partition during the NIM restore.
- C. The VIO Server partition was configured to remain a NIM client after the install.
- D. The profile data must be backed up prior to the mksysb operation.
An administrator needs to update a legacy VIO server (VIOS) partition from version 1.5 to the most current version. The rootvg of the VIOS server is presented from SAN and is managed using the SDDPCM package.
Which of the following must be considered?
- A. The latest version of SDDPCM should be included in the NIM lppsource for the upgrade.
- B. SDDPCM is now included in AIX 6. Upgrading of the package will occur automatically.
- C. SDDPCM must be upgraded immediately before the VIOS migration.
- D. The IBM supplied scripts and procedures should be followed in order to migrate VIOS with SDDPCM.
A system is being upgraded to newer hardware. What measurement can be used to make sure the new system has the correct capacity excluding disk and network?
- A. rPerf
- B. TPC-C
- C. SPECint
- D. ROLTP
