When devising a solution, you should consider what kind of undesirable results the proposed solution might have. What can you create to reverse your changes if the proposed solution does not succeed?

What will be an ideal response?

When you've found a solution that you'd like to implement, you should take steps to create a rollback plan, which allows you to return to the original state prior to the implementation of the solution, just in case something goes wrong. A rollback plan might involve saving all network device configuration files, documenting and backing up workstation configurations, and documenting wiring closet configurations.
