What is the major difference between LTWD and RTDW?

• A. RTDW requires a Layer 3 switch that can function as a router
• B. RTDW uses a Layer 2 switch only
• C. RTDW uses more displays
• D. LTWD uses a routerless approach

Answer: (B)

The key difference is whether routing between networks is used. RTDW is built on a Layer 2 switch fabric, so devices are connected in the same network segment and data is switched within that single domain—no inter-subnet routing. LTWD, on the other hand, uses routing (Layer 3) to connect multiple network segments, enabling communication across subnets and greater flexibility in topology.

In practical terms, RTDW is simpler and usually faster within one network, but limited to one broadcast domain. LTWD adds routing capability, which allows more complex network layouts and scalable growth. The other options don’t capture this main distinction: RTDW does not require a Layer 3 switch, RTDW isn’t defined by using more displays, and LTWD is not routerless.
