    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?（）

    • A、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. 
    • B、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. 
    • C、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. 
    • D、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.
