Accepted Answer

D

Question 2

Switching in Internets done by using datagram approach to packet switching at the
A)network layer.
B)application layer.
C)data link layer.
D)physical layer..

Accepted Answer

Switching in the Internet, using the datagram approach to packet switching, occurs at the network layer. This layer is responsible for routing packets across a complex network such as the Internet, ensuring data is sent from its source to its destination.

Question 3

A Circuit-Switched Network is made of a set of switches connected by physical
A)links.
B)media.
C)nodes.
D)frames.

Accepted Answer

Circuit-switched networks are made of a set of switches connected by physical links, which establish a dedicated circuit between endpoints for the duration of a communication session.

Question 4

A switch in a datagram network uses a routing table that is based on the
A)destination address.
B)sender address.
C)routing table.
D)header.

Accepted Answer

Switches in a datagram network use routing tables based on the destination address to determine how to forward packets to their final destination.

Question 5

Routing processor searches routing table is called
A)switch fabric.
B)buffer.
C)table lookup.
D)rolling table.

Accepted Answer

The process of a routing processor searching the routing table to determine the best path for data packets is referred to as "table lookup."

Question 6

A Virtual-Circuit Network (VCN) is normally implemented in the
A)session layer.
B)data link layer.
C)network layer.
D)physical layer.

Accepted Answer

The answer of A Virtual-Circuit Network (VCN) is normally implemented...

Question 7

Which frame completes entries in switching tables
A)acknowledgment frame.
B)setup frame.
C)routing frame.
D)none.

Accepted Answer

Setup frames are used to establish a connection between two devices. They contain information about the source and destination addresses, as well as the type of service requested. This information is used by the switching tables to determine how to forward the data frames.

Question 8

Virtual-Circuit Networks and datagram networks are sub categories of
A)message-switched networks.
B)packet-switched networks.
C)circuit-switched networks.
D)none of them.

Accepted Answer

Virtual-Circuit Networks and Datagram Networks are both types of Packet-Switched Networks, where data is divided into packets for transmission.

Question 9

Actual communication in a circuit-switched network requires
A)one phase.
B)two phases.
C)three phases.
D)four phases.

Accepted Answer

Actual communication in a circuit-switched network requires three phases: circuit establishment, data transfer, and circuit disconnect.

Question 10

In a packet-switched network, resources are allocated
A)randomly.
B)on demand.
C)reserved already.
D)both a and c.

Accepted Answer

In a packet-switched network, resources are allocated on demand rather than being reserved in advance. This means that as data packets arrive, they are routed based on the current network conditions and availability, allowing for more efficient use of network resources.

Question 11

In Circuit Switching, resources need to be reserved during the
A)data transfer phase.
B)teardown phase..
C)setup phase.
D)propagation phase.

Accepted Answer

In Circuit Switching, resources such as bandwidth or a specific communication path are reserved during the setup phase of the connection. This ensures a dedicated path for the duration of the communication session.

Question 12

Circuit Switched Networks are used in
A)cellular network.
B)satellite network.
C)cable network.
D)telephone network.

Accepted Answer

Circuit Switched Networks are used in telephone networks.

Question 13

Term that performs physical and data link functions of packet switch is called
A)input port.
B)output port.
C)routing processor.
D)switching fabric.

Accepted Answer

The input port is responsible for performing the physical and data link functions of a packet switch, handling the reception of packets from the physical medium and processing them at the data link layer.

Question 14

Circuit-Switched Networks are not as efficient as other two types of networks because resources are unavailable to
A)other connections.
B)same connections.
C)other switches.
D)other networks.

Accepted Answer

Circuit-switched networks are not as efficient because once a circuit is established for a connection, the resources along that path are dedicated to that connection and are unavailable to other connections until the circuit is terminated.

Question 15

Asynchronous Transfer Mode (ATM) network is an example of
A)packet switching network.
B)datagram networks.
C)virtual circuit network.
D)message switched network.

Accepted Answer

ATM is an example of a virtual circuit network, where a pre-determined path is established for the duration of a connection and all packets follow this path.

Question 16

Three methods of switching are
A)circuit switching, packet switching, and protocol switching.
B)circuit switching, packet switching, and message switching.
C)loop switching, packet switching, and message switching.
D)node switching, packet switching, and message switching.

Accepted Answer

Circuit switching, packet switching, and message switching are the three primary methods of switching used in telecommunications networks. Circuit switching establishes a dedicated communication path between nodes, packet switching divides messages into packets and sends them individually, and message switching involves the entire message being sent to the next switch where it is stored and forwarded.

Question 17

A ________switched network is made of switches connected by physical links, in which each link is divided into
A)line-switched
B)frame-switched
C)circuit-switched
D)none of the above

Accepted Answer

A circuit-switched network is characterized by the establishment of a dedicated communication path (circuit) between nodes and terminals before the users may communicate, as seen in traditional telephone networks. This involves the allocation of resources for the duration of the communication session, which differentiates it from packet-switched networks where data is divided into packets and each packet can take a different path through the network.

Question 18

A switched network consists of a series of interlinked nodes is called
A)frames.
B)packets.
C)switches.
D)links.

Accepted Answer

Switched networks are composed of nodes that are switches, which route data across the network.
