Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 459
An engineer must generate a checkpoint of the running configuration on a Cisco Nexus Switch. The checkpoint file name must be called `before_maintenance` and should be used for recovering the switch to its premaintenance state. The rollback of the checkpoint to running configuration should only occur if no errors occur. Which two configuration commands must be used to meet these requirements? (Choose two.)
Answer options
- A. rollback running-config file before_maintenance atomic
- B. checkpoint file before_maintenance
- C. rollback running-config checkpoint before_maintenance
- D. checkpoint before_maintenance
- E. rollback checkpoint file before_maintenance stop-at-first-failure
Correct answer: A, B
Explanation
The correct commands are A and B. Option A specifies an atomic rollback of the running configuration, ensuring that it only applies if no errors occur, while option B creates the checkpoint file with the required name. Options C, D, and E do not meet the requirement for atomic rollback or do not create the checkpoint as specified.
