Question

Which statements are true about routers? check all that apply.

1. Routers operate at the network layer (Layer 3) of the OSI model.
2. Routers are used to connect different networks together.
3. Routers use IP addresses to make forwarding decisions.
4. Routers operate at the data link layer (Layer 2) of the OSI model.
5. Routers are primarily used for broadcasting data within a local network.

Answer 1

Routers operate at the network layer of the OSI model, they connect different networks, and use IP addresses to make forwarding decisions.

Step-by-step explanation:

Three true statements about routers are:

1. Routers operate at the network layer (Layer 3) of the OSI model. This means they handle logical addressing and routing of data between different networks.
2. Routers are used to connect different networks together. They provide the capability to route data packets between networks, allowing for communication between devices in different networks.
3. Routers use IP addresses to make forwarding decisions. They examine the destination IP address of incoming packets to determine the best path for forwarding the packets.
