Evaluate the statement: “Most routers can also act as bridges.” Is this generally true in networking practice?

Introduction / Context:
Routers and bridges (switches) operate at different layers of the networking stack: routers at Layer 3 (network), bridges/switches at Layer 2 (data link). Although some modern devices are ‘‘multifunction’’ (for example, home gateways combining routing, switching, and access point functions), the statement about “most routers” is misleading in classical networking terms.

Given Data / Assumptions:

• ‘‘Router’’ refers to a Layer-3 device that forwards packets between IP subnets.
• ‘‘Bridge’’ refers to a Layer-2 device that forwards frames based on MAC addresses.
• Enterprise/classical context is assumed rather than consumer all-in-one devices.

Concept / Approach:
Routers and bridges serve distinct roles. A router does not inherently perform transparent bridging between interfaces; it routes between different subnets. Conversely, a bridge does not perform Layer-3 forwarding. While some platforms support both features (for example, bridge groups, BVI interfaces), that capability is model-specific and not universal across “most” routers, especially historically.

Step-by-Step Solution:

Verification / Alternative check:
Review router interface configuration defaults: interfaces are routed ports, not switchports; bridging requires explicit configuration or specific hardware modules (switching blades) not present on all routers.

Why Other Options Are Wrong:

• ‘‘True’’ overgeneralizes from combo devices to the entire router category.
• ‘‘Only when STP is disabled’’ and ‘‘Only on wireless routers’’ are unrelated caveats that mischaracterize bridging.
• ‘‘None of the above’’ is incorrect because the correct evaluation is “False”.

Common Pitfalls:
Assuming consumer ‘‘Wi-Fi routers’’ (which include a switch and AP) reflect professional router capabilities. In enterprise environments, routing and switching roles are often distinct.

Final Answer:
False
