Questions: Which statement is true about broadcast and collision domains?

The question seems to be about understanding broadcast and collision domains in networking. Let's analyze the statements provided:

1. Adding a router to a network will increase the size of the collision domain.

   • This statement is incorrect. Routers are used to segment networks into different broadcast domains, and they do not forward collision domain traffic. In fact, adding a router typically reduces the size of collision domains because each interface on a router represents a separate collision domain.

2. The size of the collision domain can be reduced by adding hubs.

   • This statement is incorrect. Hubs are layer 1 devices that do not segment collision domains; they simply repeat the signal to all ports. Therefore, adding a hub actually increases the size of the collision domain because all devices connected to the hub are in the same collision domain.

3. The more interfaces a router has, the larger the resulting broadcast domain.

   • This statement is incorrect. Each interface on a router typically represents a separate broadcast domain. Therefore, adding more interfaces to a router does not increase the size of a single broadcast domain; instead, it creates more separate broadcast domains.

In summary, none of the statements provided are true about broadcast and collision domains.
