• Edge layer

• Access layer

Which feature in the hierarchical model supports uninterrupted wireless and wired access across multiple device types?

• VLANs

• EtherChannel

• Cisco Borderless Network

• OSPF

What is the primary reason for implementing a three-tier hierarchical design over a two-tier model?
