A network engineer repeatedly saves a configuration on Catalyst switches to NVRAM using the write memory command. What action should be taken to implement the same action on Nexus switches?

Question

Options

• AUse the write memory command to save the configuration.
• BUse the alias command to use the write memory command.
• CUse the exit command to leave the configuration mode and save the configuration automatically.
• DUse the wri command to use the copy running-config startup-config command.

Explanation

On Cisco Nexus switches running NX-OS, the 'write memory' command from IOS/Catalyst does not natively exist in the same form. The correct method to save the running configuration to NVRAM (startup-config) on NX-OS is 'copy running-config startup-config'. To allow engineers familiar with Catalyst/IOS to use the familiar 'write memory' syntax, option B is correct: use the CLI alias feature ('cli alias name wr copy running-config startup-config' or 'cli alias name write memory copy running-config startup-config'). Option A is incorrect because 'write memory' is not a default valid command on NX-OS without an alias. Option C is incorrect - NX-OS does not auto-save on exit. Option D references 'wri' which is also an alias abbreviation, not the underlying mechanism.
