You run the crash utility on an Oracle Linux system after a kernel panic and use the bt - a command as shown:
crash> bt -a
PID: 286 TASK: c0b3a000 CPU: 0 COMMAND: "in.rlogind"

Which two statements are true about the purpose of the bt -a command?

• A. The output of each CPU must be requested separately.
• B. It shows stack traces of all tasks and threads.
• C. It shows stack traces of the active task on each CPU.
• D. It may help show a relationship between panicking tasks on one CPU and tasks on other CPUs.

You dynamically configure a system to concurrently run tasks A1 and A2 using these commands: # mkdir /cgroup/cpu # mount -t cgroup -o cpu cpu /cgroup/cpu # mkdir /cgroup/cpu/A1 # mkdir /cgroup/cpu/A2 # echo 5 > /cgroup/cpu/A1/cpu.shares # echo 5 > /cgroup/cpu/A2/cpu.shares # mkdir /cgroup/cpuacct # mount -t cgroup -o cpuacct cpuacct /cgroup/cpuacct You want to generate a /etc/cgconfig.conf configuration fail that contains the current cgroup
configuration on the system. Which command would you use?

• A. cgclassify
• B. cgsnapshot
• C. lscgroup
• D. cgcreate
• E. cgset
