  B it's not possible, Access-Distribution-Access maybe possible but not Access-Distribution-Distribution-Access So I think is D

• Chose B1

  Distribution switches can connect to each other, depending on physical location and design, not to mention the case in which access switches connected to the same distribution switch. The traffic does not have to go a level up to the core switch. This is why the 3-tier network does not guarantee equal hop number or latency. In comparison, a spin-leaf topology eliminates horizontal connections between switches at the same level.

  Yeah but still, think about it as in the CCNA exam logic, we study cisco materials, where, talking about 3-tier topology, distribution more often doesn't connect directly to each other. For two access switches connected on the same distribution, traffic: access-distribution-acces (which is not listed here). Also as the question precise "separate switch" we should consider that such topology, in a lan campus, are not in the same building. Therefore, traffic goes like : access-distribution-core-distribution-access
