Oracle Solaris 11 Advanced System Administrator — Question 24

You have installed software updates to a new boot environment (BE) and have activated that the booting to the new BE, you notice system errors. You want to boot to the last known good configuration.
Which option would you use on a SPARC system to boot to the currentBE boot environment?

Answer options

• A. boot –L currentBE
• B. boot –Z rpool/ROOT/currentBE
• C. boot –a Enter the currentBE dataset name when prompted.
• D. boot rpool/ROOT/currentBE
• E. boot –m currentBE
• F. beadm activate currentBE

Correct answer: F

Explanation

The correct answer is F, 'beadm activate currentBE', because this command specifically activates the desired boot environment. The other options either attempt to boot directly into a specified dataset or use incorrect syntax for changing the active boot environment, which would not achieve the intended outcome.
