Explanation

Option D is correct because Cisco devices expose the serial number in multiple locations - physically on the hardware and logically through the operating system. You can find it on the front panel (often on a label or LCD), on the back panel (typically a sticker near the power supply or chassis), and in software via commands like show version or show inventory in Cisco IOS/NX-OS. Options A, B, and C are each only partially correct - none of them alone captures all the places a serial number can appear, making them incomplete as standalone answers.

Memory tip: Think "FBS - Front, Back, Software." Cisco gives you three ways to find the serial because one method might not always be accessible (e.g., the device is rack-mounted with the back inaccessible, or the label is worn off), so the software fallback via show version is especially valuable in real-world scenarios.
