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.
