Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 421

A network engineer must perform a backup and restore of the Cisco Nexus 5000 Series Switch configuration. The backup must be made to an external backup server. The only protocol permitted between the Cisco Nexus Series switch and the backup server is UDP. The backup must be used when the current working configuration of the switch gets corrupted. Which set of steps must be taken to meet these requirements?

Answer options

• A. 1. Perform a running-config backup to an SFTP server. 2. Copy backup-config from the SFTP server to the running-config file.
• B. 1. Perform a startup-config backup to a TFTP server. 2. Copy backup-config from the backup server to the running-config file.
• C. 1. Perform a running-config backup to an SCP server. 2. Copy running-config in the boot flash to the running-config file.
• D. 1. Perform a startup-config backup to an FTP server. 2. Copy startup-config in the boot flash to the running-config file.

Correct answer: B

Explanation

The correct answer is B because TFTP is a UDP-based protocol that allows for the required backup and restore process. Options A and C use SFTP and SCP, which are not UDP-based, and option D uses FTP, which is also not permitted as it is TCP-based. Therefore, only option B meets the criteria of using UDP with TFTP.
