Drag the network characteristic on the left to the design method on the right which will best ensure redundancy at the building distribution layer.
Answer: 
Explanation:
Correct Answer
Layer 2 between distribution and access layers, with a Layer 3 link between the distribution
switches
-> Support Layer 2 VLANs spanning multiple access layer switches across the distribution
switches
Layer 2 between distribution and access layers, with a Layer 2 link between the distribution
switches-> FHRP for convergence, no VLANs span between access layer switches across the distribution
switches
VSS -> Convergence (FHRP) is not an issue
The following are recommended best practices at the distribution layer:

Hi, this update is great stuff. Just one thing though, the answer in this Q12 (top 2 boxes) appears to be different to the answer in Q13 following. Thanks, Paul
Seems like the answer is wrong. http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Campus/HA_campus_DG/hacampusdg.html#wp1108899
That should be:
Layer 2 between distribution and access layers, with a Layer 3 link between the distribution switches FHRP for convergence, no VLANs span between access layer switches across the distribution
switches
Layer 2 between distribution and access layers, with a Layer 2 link between the distribution switches Support Layer 2 VLANs spanning multiple access layer switches across the distribution
