Suggested Answer: ABD 🗳️
A: The beadm utility includes support for creating and administering non-global zone boot environments.
Note: A boot environment is a bootable instance of the Oracle Solaris operating system image plus any other application software packages installed into that image. System administrators can maintain multiple boot environments on their systems, and each boot environment can have different software versions installed.
