Router

What is the primary function of a router?

• Amplify signals in a network

• Forward packets between different networks

• Convert data between different protocols

• Store and manage MAC addresses

Which layer of the OSI model does a router operate at?

• Application Layer (Layer 7)

• Transport Layer (Layer 4)

• Network Layer (Layer 3)

• Data Link Layer (Layer 2)

How do routers determine the best path for data packets?

• Using MAC addresses

• Using routing tables and algorithms

• Broadcasting packets to all devices

• Randomly selecting a path

Which of the following is NOT a function of a router?

• Breaking up broadcast domains

• Filtering traffic based on IP addresses

• Connecting multiple networks

• Forwarding data based on MAC addresses

What type of routing requires manual updates by a network administrator?

• Static Routing

• Dynamic Routing

• Link-State Routing

• Distance-Vector Routing

Which of the following is an example of a dynamic routing protocol?

• RIP (Routing Information Protocol)

• ARP (Address Resolution Protocol)

• FTP (File Transfer Protocol)

• MAC (Media Access Control)

What does a router do when it receives a packet with an unknown destination?

• Broadcasts it to all connected devices

• Discards the packet

• Stores the packet for later transmission

• Sends it back to the sender

Which of the following best describes a broadcast domain?

• A group of devices that share the same IP address

• A network segment where all devices receive broadcast messages

• A physical network connection between routers

• A secure network segment

What is the main disadvantage of distance-vector routing protocols?

• They do not consider the number of hops in a route

• They fail to account for network congestion and speed

• They require high processing power

• They cannot be used in large networks

How do routers help prevent broadcast storms?

• By discarding broadcast packets

• By forwarding all packets to every network

• By increasing the number of broadcast domains

• By operating at the Physical Layer
