What is a key benefit of a layered network design?
The correct answer is C. increased flexibility. A layered network design separates the network into distinct functional tiers so that each layer can be scaled or modified independently, making the overall network highly flexible.

Why each option
A layered network design separates the network into distinct functional tiers so that each layer can be scaled or modified independently, making the overall network highly flexible.
Layered designs generally require more equipment and dedicated hardware per tier than flat designs, so cost savings is not a primary benefit of the model.
Security improvements depend on the policies and controls configured within a design, not on the layered topology itself, so security is not a defining benefit.
The modular hierarchy of a layered design - typically core, distribution, and access - isolates changes to a single tier, allowing capacity upgrades, protocol changes, or new service introductions at one layer without restructuring the rest of the network.
Broadcast domain reduction is achieved through deliberate VLAN and subnetting decisions, not as an inherent outcome of adopting a layered topology.
