单选题 Companycom tells the technical sales specialist that recent announcements state that virtual lan in the datacenter is the best option. The customer wants to use interpartition communication to save on adapters and increase performance. The systems are going to have shared and dedicated processor partitions. Some of the partitions will be running AIX 5.2 and some will be running AIX 5.3. The second p5 590 will be running a mixture of AIX 5.3 and Linux partitions with 2.6 kernel. What limitations of vlan/interpartition communication should be discussed with this customer?（）
Virtual Ethernet uses the system processors for all communication functions instead of offloading that load to processors on network adapter cards. Virtual Ethernet is supported on AIX 5L and Linux 2.5 and above.
Virtual Ethernet can be used within groups of shared OR groups of dedicated processor partitions, but not both simultaneously. Virtual Ethernet comes with AIX 5L, and is supported in AIX 5.2 or AIX 5.3 partitions, but not Linux.
Virtual Ethernet can be used in both shared and dedicated processor partitions. Virtual Ethernet can run in an AIX 5.3 or Linux 2.6 Kernel, but not AIX 5.2 partitions. Virtual Ethernet can only connect partitions within a single system.
Virtual Ethernet uses the system processors for all communication functions instead of offloading that load to processors on network adapter cards. Virtual Ethernet can connect partitions between systems if the HMC is shared between systems.
单选题 Companycom will be using Virtual IO Server to share Ethernet adapters. What can be done to prevent network failure of the client if a Virtual IO Server goes down?（）

单选题 Companycom is planning to do server consolidation on POWER5. The customer has a test environment, a QA environment and a production environment for two applications. Both the test and QA environments are very small and are only utilized when new releases are being developed and tested. They require less than 1 CPU each. Both production applications require 2 CPUs for day-to-day operation and can require up to an additional 2 CPUs each during abrupt peak requirements. What is the best design for the LPARs?（）
Use micropartitioning for test and QA environments, and DLPAR for the production applications
Use micropartitioning for test and QA environment, and CPU pooling for the production applications
Create standard LPARs for all test, QA, and production applications to keep all partitions separate and isolated.
Create DLPAR partitions for all test, QA, and production applications to keep test from disturbing production environment.
