Device-alias distribute Command

B.

The device-alias distribute command is used in Cisco MDS (Multilayer Director Switch) SAN (Storage Area Network) switches to distribute the device alias configuration to other switches in the same Fabric Services region.

Answer A is the correct answer, as it accurately describes the function of the device-alias distribute command. When this command is executed on a switch in a Cisco Fabric Services region, it sends the device alias configuration to all other switches in the same region, allowing all switches to have the same device alias configuration.

This command is particularly useful in large SAN environments, where there may be many switches with multiple device aliases. By using the device-alias distribute command, administrators can ensure that all switches in the same Fabric Services region have consistent device alias configurations, reducing the likelihood of errors or configuration mismatches.

Answer B is not correct, as the device-alias distribute command does not require a commit to be executed. Answer C is also incorrect, as the command does not change the distribution mode for device aliases. Answer D is not correct, as the command does exist and is a valid command in Cisco MDS switches.
