The distribution layer of the Cisco hierarchical internetworking model is where policies should be implemented.

• A. Addresses
• B. Wireless standards
• C. Policies
• D. Routing protocols

Answer: (C)

Traffic policies are implemented and enforced at the boundary between users and the rest of the network. The distribution layer acts as the control point where you apply rules that govern how traffic is handled as it moves from access devices toward the core. This includes security measures like access control lists, quality of service settings to prioritize or shape traffic, and policy-based routing or route redistribution between VLANs. Because the focus here is on governing traffic behavior and applying rules, the distribution layer is where policies belong. Addresses are just identifiers for devices, not how traffic is governed. Wireless standards describe how wireless devices communicate and aren’t about policy enforcement in the distribution layer. Routing protocols deal with learning and sharing routes; while routing decisions can be influenced by policies, the question targets where policies themselves are implemented, which is the policy layer at this node.
