An engineer must open a support case with Cisco TAC. Which two commands verify the model and serial number of a controller? (Choose two)

The `show sysinfo` command provides general system information but typically does not display the detailed model and serial numbers in a format directly used for TAC cases.

The `show udi` command displays the Universal Device Identifier (UDI), which includes the product identifier (PID) and serial number (SN) of the controller, crucial information for TAC.

The `show inventory` command provides detailed information about the hardware components of the controller, including their model numbers and serial numbers, which are essential for identifying the device for support.

The `show boot` command displays information related to the boot parameters and image of the controller, not its hardware model or serial number.

The `show tech-support` command gathers extensive diagnostic information, but it is an aggregation of many commands and often includes too much data when only specific model and serial numbers are needed.
