NetBEUI (NetBIOS Extended User Interface) characteristics: Which of the following statements is not true about NetBEUI?

Introduction / Context:
NetBEUI is a lightweight transport once common on small Windows LANs. It emphasizes simplicity and low overhead but does not scale across routers. Understanding its traits helps compare it with routable protocols like TCP/IP and IPX/SPX used in larger or segmented networks.

Given Data / Assumptions:

• Scope: small, flat LANs without routing.
• Priority: ease of setup and minimal tuning.
• Historically used for quick peer-to-peer file and printer sharing.

Concept / Approach:
The defining limitation of NetBEUI is that it is not routable. It broadcasts for name resolution and relies on a single broadcast domain. While quick and self-configuring, it cannot traverse IP routers, making it unsuitable for multi-subnet or wide-area environments.

Step-by-Step Solution:

Verification / Alternative check:
In multi-subnet designs, NetBEUI traffic does not pass through IP routers. Administrators historically migrated to TCP/IP to enable routing, centralized services, and Internet connectivity.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming NetBEUI can be routed like TCP/IP; overlooking broadcast overhead as LANs grow.

Final Answer:
Routable.
