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?

A. B. C. D.B.
The correct answer for this scenario is B: 1. Perform a startup-config backup to a TFTP server. 2. Copy backup-config from the backup server to the running-config file.
Here's a detailed explanation of the steps and the reasoning behind them:
Step 1: Perform a startup-config backup to a TFTP server The first step is to perform a backup of the switch's startup-config to an external backup server using TFTP (Trivial File Transfer Protocol). TFTP is a simple protocol that can be used to transfer files between network devices. The startup-config is the configuration file that is loaded when the switch boots up, so it contains the most important configuration information for the switch. This backup will be used in case the current working configuration of the switch gets corrupted.
Step 2: Copy backup-config from the backup server to the running-config file If the current working configuration of the switch gets corrupted, the backup-config file from the TFTP server can be used to restore the startup-config. The switch will load the startup-config file when it boots up, so this will restore the switch to its previous configuration. The backup-config file should be copied from the TFTP server to the running-config file in order to make the switch use the backed up configuration.
The other answer choices are incorrect for the following reasons:
A. Perform a running-config backup to an SFTP server. Copy backup-config from the SFTP server to the running-config file. This answer is incorrect because it suggests using a running-config backup instead of a startup-config backup. The running-config file contains the current configuration of the switch, so if it gets corrupted, the backup file will also be corrupted. Also, the protocol permitted between the switch and the backup server is UDP, and SFTP uses TCP (Transmission Control Protocol), so this protocol is not permitted in this scenario.
C. Perform a running-config backup to an SCP server. Copy running-config in the boot flash to the running-config file. This answer is incorrect because it suggests using a running-config backup instead of a startup-config backup. As mentioned earlier, the running-config file contains the current configuration of the switch, so if it gets corrupted, the backup file will also be corrupted. SCP (Secure Copy Protocol) is not supported by the Cisco Nexus 5000 Series switch, so this protocol cannot be used for the backup.
D. Perform a startup-config backup to an FTP server. Copy startup-config in the boot flash to the running-config file. This answer is incorrect because it suggests using FTP (File Transfer Protocol) instead of TFTP. FTP uses TCP, which is not permitted in this scenario. Also, copying the startup-config file from the boot flash to the running-config file will not restore the switch's configuration to the backed up configuration. The backup-config file should be copied from the TFTP server to the running-config file instead.
