QuestionQ20

Configuration Basics

You successfully committed a configuration change. You now discover that an issue exists and must revert to the previous configuration.

Which command, entered in configuration mode and then committed, accomplishes this task?

  • A show | compare
  • B save config
  • C rollback 0
  • D rollback 1
Explanation

In Junos, rollback configuration 0 is the current, most recently committed configuration, while rollback configuration 1 is the immediately preceding committed configuration. rollback 1 loads that prior configuration as the candidate configuration; committing it activates the restored configuration.
