Which two statements are true?（） It is possible for more than two threads to deadlock at once.。 The JVM implementation guarantees that multiple threads cannot enter into a deadlocked state.。 Deadlocked threads release once their sleep() method's sleep duration has expired.。 Deadlocking can occur only when the wait(), notify(), and notifyAll() methods are used incorrectly.。 It is possible for a single-threaded application to deadlock if synchronized blocks are used incorrectly.。 If a piece of code is capable of deadlocking, you cannot eliminate the possibility of deadlocking by inserting invocations of Thread.yield().。
AIX 5L and SUN Solaris have differing approaches at handling processor failures. Which statement best describes how AIX handles processor failures？（） 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.。 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.。 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.。 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.。
