Which two options describe how to override the default boot behavior of an Oracle Solaris 11
SPARC system to boot the system to the single-user milestone?

A.
from the ok prompt, issue this command:boot -m milestone=single-user

B.
From the ok prompt, issue this command:boot -m milestone/single-user

C.
From the ok prompt, issue this command: boot -milestone=single-user

D.
From the ok prompt. issue this command:boot -s

E.
From from the ok prompt, issue this command:boot -m milestone=s

Explanation:
By default, Solaris will boot to the pseudo milestone all and start all services. This
behaviour can be changed at boot time using either -s to reach single-user, or the new SMF
option -m milestone=XXX (see kernel(1M) for a list of the bootable milestones) to select an
explicit milestone.
Note: boot -s is the same as: boot -m milestone=single-user
with the difference being that the former is a lot less to type and is what most SysAdmins will be
familiar with.
