What is a primary benefit of a modular chassis-based switch?

A primary benefit of a modular chassis-based switch is scalability. These types of switches are designed with a modular architecture that allows users to add or swap out components, such as line cards and power supplies, to accommodate increased network demands. This flexibility means that as a network grows or changes, additional modules can be integrated to support new technologies, increased bandwidth, or more ports without the need to replace the entire switch.

This scalability is particularly advantageous in enterprise environments where traffic patterns and requirements may evolve over time. In contrast, fixed configuration switches do not offer this level of flexibility, as their capabilities are limited to the original design. The ability to easily upgrade specific components helps organizations manage their networking needs efficiently while optimizing their investment over time.

Other options, like cost-efficiency, space requirements, or limited interfaces, do not align with the inherent strengths of modular chassis-based switches, which are primarily defined by their scalability and adaptability in growing networks.
