What is the major difference between the local terminal display workstation (LTWD) and the remote terminal display workstation (RTDW)?

• A. The RTDW requires a Layer 3 switch that can function as a router
• B. The LTWD has more display resolution
• C. The RTDW uses fiber optic connections only
• D. The LTWD needs a separate power supply

Answer: (A)

Understanding how traffic to a terminal display is carried across networks helps explain the difference. A local terminal display workstation stays on the same local network where switching is enough, so it typically doesn’t require routing. A remote terminal display workstation, however, sits across network boundaries and may cross subnets, so the path must be able to route IP packets. That’s why a Layer 3 switch that can function as a router is needed for the remote setup—it provides the IP routing and inter-network connectivity that the RTDW requires. The other statements don’t reflect a fundamental design distinction: display resolution isn’t inherently tied to local versus remote, fiber optic only isn’t a must for remote access, and a separate power supply isn’t a defining difference.
