Q30Advanced Enterprise Campus Networks
Refer to the exhibit. An engineer is designing a Layer 2 campus network. The design must provide fast convergence and use as much bandwidth as possible between layers. The distribution switches support VSS; however, license limitations prevent the use of all routing protocols. Which solution must the engineer choose?

Could be, but theres a reason they wrote "Distribution switches do support VSS"
So it means we should be using MEC (Multi Chassis Etherchannel)
Answer B is 100% right.
B 2
Selected Answer: B
set up StackWise Virtual on the distribution layer and then configure MEC

Selected Answer: B
MEC (Multi Chassis Etherchannel)
B 2
Selected Answer: B
Multi-Chassis EtherChannel. With inter-chassis SSO, the total switchover time stays within a second and when a chassis fails or during a switchover event, all the links on that chassis go down. External switches that are single-homed into the failed chassis will see an outage. It is recommended to dual-home all connections to the SV pair using MEC technology, which mainly load-balances traffic across links, and keeps the traffic impact minimal in the event of chassis or link failure.

For me, the answer is A: Etherchannel
