During the design of a new data center, a company requires that access switches be placed near servers without requiring a one-to-one ratio of switches to network racks. Which switch layout must be used?
I think it is A -> The End of Row switch provides connectivity to the hundreds of servers within that row. Therefore, unlike Top of Rack where each rack is its own managed unit, with End of Row the entire row of servers is treated like one holistic unit or “Pod” within the data center. Network upgrades or issues at the End of Row switch can be service impacting to the entire row of servers. The data center network in this design is managed “per row”, rather than “per rack” as per http://bradhedlund.com/2009/04/05/top-of-rack-vs-end-of-row-data-center-designs/
It's A - End of row. The request states that it does NOT require a switch per rack
