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.)
To generate a checkpoint and ensure a rollback occurs only if no errors occur, the correct commands are 'checkpoint before_maintenance' to create the checkpoint and 'rollback running-config file before_maintenance atomic' to restore the configuration using the atomic method.
The question explicitly asks for a file to be generated and to rollback from file, so A and B are the correct answers.
There are two key requirements in the question: 1. Configuration rollback from a file -> B 2. Rollback will be performed only in there are NO ERRORS -> atomic rollback method must be used = A

A and B We need to give a file name for checkpoint hence we need "checkpoint file ..." Command. We need "atomic" flag and execute rollback from a file to the running configuration, hence we need "rollback running-config file ... atomic" command.
yes C and D!
I agree
The answer is totally incorrect. The correct answer is CD https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/6-x/system_management/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide/sm_7rollback.html#task_742A244D6D954A37BE3DBA8E740D665E:~:text=all%20checkpoint%20files.-,Configuration%20Example%20for%20Rollback,-This%20example%20shows
I am so sorry. I was wrong. The answer is correct. Rollback should be done from file. The right answer is AB.
Why should be from file and not from non-file ?

A,B look correct.
shouldn't it be AD?
The Answer A & B Seems correct atomic—Implement a rollback only if no errors occur. best-effort—Implement a rollback and skip any errors. stop-at-first-failure—Implement a rollback that stops if an error occurs.
Configuration Example for Rollback This example shows how to create a checkpoint file and then implements a best-effort rollback to a user checkpoint name: checkpoint stable rollback running-config checkpoint stable best-effort
