An engineer chose to design an architecture where distribution switches are in VSS and are connected to access switches using Multichassis Etherchannel. What is
the resulting topology?

A.
Looped

B.
Ring

C.
Hybrid

D.
Star

Explanation:
What is multichassis EtherChannel?
A:
Multichassis EtherChannel (MEC) is a Layer 2 multipathing technology. This form of EtherChannel allows a connected node to terminate the EtherChannel
across the two physical Cisco Catalyst 6500 Series Switches that make up the VSS leading to creating simplified loop-free Layer 2 topology. Using MEC in VSS
topology results in all links being active and at the same time provides for a highly available topology without the dependency of Spanning Tree Protocol. With the
introduction of 12.2(33)SXI, the virtual switching system supports a maximum number of 512 MECs.
