【单选题】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.
