Cisco Confidential 11 Hierarchical Network Design Distribution Layer

Play an AI-generated podcast conversation about this lesson

What is a two-tier collapsed core design in a hierarchical network?

Using three different layers for network functions

Having separate distribution and core layer devices

Combining distribution layer and core layer functions in a single device (correct)

Implementing Layer 3 switching only at the access layer

What is the primary purpose of implementing a two-tier collapsed core design?

To eliminate the need for Spanning Tree Protocol (STP)

To increase network complexity for larger businesses

To reduce network cost for smaller businesses (correct)

To implement Layer 3 switching at the core layer

What is a drawback of a traditional switched hierarchical design in the enterprise campus?

Route summarization is configured at the access layer

Spanning Tree Protocol (STP) allows load balancing between redundant links

Layer 3 boundary is pushed towards the core layer

Only one of the redundant links can be active due to STP (correct)
