問題文
A retailer's 900 stores each run a small switch stack. The architect is deciding between extending one flat segment across all stores over the wide-area network and giving each store its own segment with routing between them. Store systems need to discover a local receipt printer by broadcast. Which design should be chosen?
選択肢
- One flat segment per region with routing between regions, because that balances the size of the broadcast domain against the number of routed hops.
- One segment per store with routing between stores, because the broadcast that finds the printer stays local and a fault in one store cannot flood the others.
- One flat segment across all stores, since printer discovery then needs no extra configuration and one large range keeps the addressing plan simple.
- One segment per store with a translation device at each store boundary.
