Which two statements are true?

Consider a cgroup configuration in the /etc/cgconfig.conf file: mount {
cpuset = /cgroup/A; cpu = /cgroup/A; cpuacct = /cgroup/cpuacct;
}
group A1 { perm{ admin { uid = root; gid = wheel;
}
task{ uid = root; gid = users;
}
}
cpuset{
cpuset.mems-!On;
cpuset.cpus-!0″;
}
cpu{
cpu shares=”5”;
}
}
group A2 { perm{ admin { uid = root; admin { uid = root gid = root;
}
task{ uid = root; gid = users;
> fe
}
cpuset{
cpuset.mems=”0″;
cpuset.cpus^T;
}
cpu{
cpu.shares=n5”;
}
}
