Prevent threads from executing
None of the above
Q18
Q18 In most modern operating systems, a new thread is created by:
Forking a process
Using a thread library function like pthread_create in C
Cloning the operating system
Writing a new kernel module
Q19
Q19 If a program with multiple threads is using more CPU resources than expected, you should first:
Check for infinite loops within threads
Increase the number of CPUs in the system
Delete unused threads
None of the above
Q20
Q20 A thread is unable to proceed with its execution because it's waiting for a resource that's held by another thread. This scenario describes:
A deadlock
A segmentation fault
A syntax error
A runtime error
Q21
Q21 When a process is not responding to user inputs, a likely cause is:
The process is in a deadlock state
