What is the minimum slot requirement for a Supervisor Engine 720 in a 6-slot chassis?

To determine the minimum slot requirement for a Supervisor Engine 720 in a 6-slot chassis, it's essential to understand the architecture of Cisco's modular chassis. The Supervisor Engine 720 serves as the central management and control component of the chassis, and it is designed to occupy specific slots to function correctly.

The Supervisor Engine typically requires two consecutive slots. In a standard 6-slot chassis configuration, the initial slots are usually designated for the Supervisor Engine and other components like line cards and service modules. For the Supervisor Engine 720, the commonly accepted slots for installation are Slots 1 and 2.

Choosing Slots 5 and 6 would not be appropriate because those slots are typically used for line cards or other interface modules, not the Supervisor Engine. Additionally, Slots 3 and 4, while potentially usable for other types of components, would not be the designated slots to house the Supervisor Engine 720, which is meant for Slots 1 and 2.

Thus, the correct answer aligns with the standard configuration practice that assigns specific locations within the chassis framework to ensure that the Supervisor Engine can properly manage and maintain the system's operations.
