Networking Concepts Quiz

Which of the following describes the primary function of forwarding in networking?

• Transmitting data between two routers

• Managing the network's routing table

• Delivering data packets to the appropriate output interface of a router

• Deciding the path for data packets to travel from source to destination

What is the key difference between virtual circuit networks and datagram networks?

• Virtual circuit networks do not maintain any path state information, while datagram networks do.

• Datagram networks establish a predefined path for data transfer, while virtual circuit networks route each packet independently.

• Virtual circuit networks establish a predefined path for data transfer, while datagram networks route each packet independently.

• Virtual circuit networks are more reliable than datagram networks.

Which of the following is a characteristic of a datagram network?

• The path for data transfer is set up before sending data.

• All packets follow the same route from source to destination.

• Each packet is treated independently, with no predetermined path.

• It guarantees end-to-end delivery of packets.

In a router, which function is responsible for checking the destination address of an incoming packet?

• Input processing

• Output processing

• Forwarding

• Switching

What is the role of input processing in a router?

• To manage the output queue for the router

• To handle error checking and ensure data integrity

• To check the destination address of packets and forward them to the correct output interface

• To determine the best route for the packet based on routing protocols

What is a key feature of virtual circuit (VC) networks?

• They establish a fixed, pre-negotiated path before data transfer begins.

• They do not require any form of path management.

• They use separate routing tables for each packet.

• They operate using a best-effort delivery model.

Which of the following is an example of a network service model used in both VC and Datagram networks?

• Best-effort service

• Reliable connection-oriented service

• Connectionless service

• Guaranteed delivery service

How does a router determine the next hop for an incoming datagram in a datagram network?

• By consulting its routing table based on the destination address

• By following a predetermined virtual circuit path

• By checking the input buffer for previous packets

• By using a fixed path established at the beginning of the connection

What distinguishes a datagram network from a virtual circuit network in terms of packet handling?

• Datagram networks maintain a fixed route for all packets, while virtual circuit networks use dynamic routing.

• Datagram networks ensure in-order delivery of packets, while virtual circuit networks do not.

• Virtual circuit networks maintain state information and handle packets in sequence, while datagram networks do not.

• Virtual circuit networks are more flexible and adaptable than datagram networks.

What is the purpose of switching in a router?

• To encrypt data packets before transmission

• To manage the routing table for outbound packets

• To manage the connection setup in a virtual circuit network

• To move data packets from the input buffer to the appropriate output interface
