Which three statements describe Solaris 11 boot environments (BEs)?

Question

Options

• AA full backup of your OS image is provided.
• BPackages can be installed and uninstalled in an inactive BE.
• CThe OS can be upgraded in an active BE while the system is live without impacting production.
• DA new BE can be created from the snapshot of an existing BE.
• EA BE can become active without rebooting the system.
• FAn active BE can be unmounted and upgraded without impacting production.

• A
  6% (2)
• B
  81% (26)
• E
  3% (1)
• F
  9% (3)

Explanation

Solaris 11 Boot Environments (BEs) are ZFS-based snapshots of the OS that allow safe system modifications. B is correct because you can install or remove packages into an inactive BE (using pkg -R or beadm) without touching the running system. C is correct because running pkg update on a live system automatically creates a new BE in the background, leaving the active production environment completely unaffected until you choose to reboot into it. D is correct because BEs are built on ZFS clone/snapshot technology, so beadm create can derive a new BE from a snapshot of any existing BE.

Why the distractors are wrong:

• A - A BE is not a full backup; it's a space-efficient ZFS clone that shares unchanged data blocks with the source BE.
• E - Switching the active BE always requires a reboot; you can designate a BE for next boot, but it won't activate until the system restarts.
• F - You cannot unmount the active BE because it is the live, running OS; only inactive BEs can be mounted/unmounted.

Memory tip: Think of BEs with the acronym SIC - Snapshot-based creation (D), Inactive BE modification (B), and Continuous uptime during upgrades (C). If an answer claims you can unmount the active BE or avoid rebooting to switch BEs, it's a trap.
