Explanation

The show inventory command is used on Cisco devices to display detailed information about the hardware components installed, including: Product Identifier (PID) Version Identifier (VID) Serial Number (SN) Description of the component In the exhibit, the output clearly shows: NAME: "Chassis", DESCR: "Cisco ISR4451-X/K9" PID: ISR4451-X/K9, VID: V01, SN: FCW2134L0SH This confirms that show inventory is the correct command to retrieve the serial number and hardware inventory details. show version provides some system information and sometimes includes serial numbers, but it's not as reliable or detailed for component-level hardware info. show idprom is not commonly used and not supported on all platforms. show platform provides platform-specific info but not typically the serial number.
