AIX 5L and SUN Solaris have differing approaches at handling processor failures. Which statement best describes how AIX handles processor failures？（）A、If AIX discovers a processor with too many recoverable errors during runtime， it will dynamically turn off that processor， while the rest of the system keeps running.B、If AIX detects a failing processor it will automatically move all resources to another processor. The failed processor can be hot-swapped and the new replacement becomes the active processor.C、If AIX determines a processor is failing， it will perform diagnostics to determine which processor function can be disabled and dynamically reallocate all CPU and memory resources thus isolating the failure condition and preventing a reboot.D、If AIX senses a processor level error condition， internal diagnostics are activated to determine the severity of the problem. After the failure threshold is met， a message is broadcast to the service processor informing the operator to perform a system reboot.

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.
