Question 1

When a router forwards incoming packets closer to their destination hosts,this is ________.
A)routing
B)switching
C)bridging
D)hopping

Accepted Answer

Routing is the process of forwarding packets closer to their destination using a routing table and determining the best path for the packet to reach its destination based on destination IP address, network topology, and other metrics. Switching is the process of forwarding packets between devices on the same network or VLAN, and bridging is the process of forwarding packets between different networks or VLANs. Hopping is not a networking term. Therefore, the best choice is routing.

Question 2

UDP is reliable.

Accepted Answer

UDP (User Datagram Protocol) is not reliable because it does not guarantee delivery or order of packets. It is a faster and more efficient protocol than TCP but sacrifices reliability for speed.

Question 3

TCP is ________.
A)connectionless
B)unreliable
C)Both A and B
D)Neither A nor B

Accepted Answer

TCP (Transmission Control Protocol) is a connection-oriented protocol and is known for its reliability in ensuring data transfer without errors. Therefore, it is not connectionless (choice A) or unreliable (choice B).

Question 4

In a network mask,the 1s correspond to the ________.
A)network part
B)subnet part
C)host part
D)None of the above.

Accepted Answer

The 1s in the network mask represent the network part of the IP address. The network part is used to identify the network that a device belongs to, while the remaining bits identify the specific device on that network. Therefore, none of the options B and C are correct because they refer to parts of the IP address that are identified by the 0s in the network mask.

Question 5

An internal router only connects different IP ________.
A)subnets
B)networks
C)Both A and B
D)Neither A nor B

Accepted Answer

An internal router only connects different IP subnets. Subnets are a subdivision of a single network that allows for better management and organization of network resources. An internal router is used to connect different subnets within the same network. It helps to manage the flow of network traffic and improve network performance by reducing congestion.

Question 6

In a subnet mask,the 1s correspond to the ________.
A)network part
B)subnet part
C)host part
D)None of the above.

Accepted Answer

The answer of In a subnet mask,the 1s correspond to...

Question 7

________ operates at the transport layer.
A)TCP
B)UDP
C)Both A and B
D)Neither A nor B

Accepted Answer

Both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) operate at the transport layer of the OSI (Open Systems Interconnection) model. TCP is a connection-oriented protocol that provides reliable data delivery and guarantees that packets are received in order, while UDP is a connectionless protocol that does not guarantee reliable data delivery or packet ordering. Both protocols are widely used in networking applications, and the choice between them depends on the specific requirements of the application.

Question 8

A mask has ________ bits.
A)8
B)16
C)24
D)32
E)The number of bits varies.

Accepted Answer

The answer of A mask has ________ bits.
A)8
B)16
C)24
D)32
E)The number of...

Question 9

When a network mask is applied to any IP address on the network,the result is the IP address' network part followed by zeros.

Accepted Answer

This statement is true. The network mask is used to determine the network part of an IP address by separating the bits that represent the network portion from the bits that represent the host portion. When the mask is applied, any bits in the host portion of the IP address are set to zero, resulting in the network part of the address followed by zeros.

Question 10

Which of the following is reliable?
A)TCP.
B)IP.
C)Both A and B
D)Neither A nor B

Accepted Answer

TCP (Transmission Control Protocol) is considered reliable because it ensures data is delivered accurately and in the correct order by establishing a connection and using error-checking mechanisms. IP (Internet Protocol), on the other hand, does not guarantee delivery or order, making it unreliable.

Question 11

Which of the following is one of the three parts of an IP address?
A)Subnet part.
B)Mask part.
C)Both A and B
D)Neither A nor B

Accepted Answer

An IP address consists of three parts; Network part, Subnet part, and Host part. The subnet part determines the size of the local network or subnetwork. The mask part, on the other hand, is used to determine which part of the IP address is for the network and which part is for the host. Therefore, the subnet part is one of the three parts of an IP address.

Question 12

UDP is ________.
A)connection-oriented
B)unreliable
C)Both A and B
D)Neither A nor B

Accepted Answer

UDP (User Datagram Protocol) is an unreliable protocol because it does not guarantee the delivery of packets to the destination. Unlike TCP, UDP does not establish a connection before transmitting data. Therefore, there is no error checking, retransmission mechanism available, or flow control in UDP.

Question 13

The network part of an IP address is ________ bits long.
A)8
B)16
C)24
D)32
E)The size of the network part varies.

Accepted Answer

The size of the network part of an IP address varies depending on the class of the address or the subnet mask used.

Question 14

A border router's main job is to connect different subnets in the same network.

Accepted Answer

A border router connects different networks, not just subnets within the same network. Its main job is to forward packets between these networks while also enforcing network policies and security measures.

Question 15

TCP is reliable.

Accepted Answer

TCP (Transmission Control Protocol) provides a reliable, connection-oriented communication service, guaranteeing the delivery of packets in the correct order and without errors.

Question 16

Which of the following is connectionless?
A)TCP.
B)IP.
C)Both A and B
D)Neither A nor B

Accepted Answer

IP is a connectionless protocol. It sends packets of data without establishing a dedicated end-to-end connection between the sender and receiver. TCP, on the other hand, is a connection-oriented protocol that establishes a reliable connection between the communicating parties before transmitting data.

Question 17

Which of the following is connectionless?
A)TCP.
B)UDP.
C)Both A and B
D)Neither A nor B

Accepted Answer

UDP (User Datagram Protocol) is a connectionless protocol as it does not establish a dedicated end-to-end connection before transmitting data packets. Instead, it sends individual packets called datagrams, which are transmitted independently and can take different routes to reach the destination. In contrast, TCP (Transmission Control Protocol) is a connection-oriented protocol and establishes a reliable connection before transmitting data packets.

Question 18

Which of the following is reliable?
A)TCP.
B)UDP.
C)Both A and B
D)Neither A nor B

Accepted Answer

TCP (Transmission Control Protocol) is a reliable transport protocol, providing error-checking, retransmission, and flow control mechanisms. UDP (User Datagram Protocol), on the other hand, is not reliable and does not provide these mechanisms. Therefore, only choice A is reliable.

Question 19

The total length of an IP address is ________ bits.
A)8
B)16
C)24
D)32
E)The length of IP addresses varies.

Accepted Answer

The length of an IP address is 32 bits, which is divided into four octets of 8 bits each.

Question 20

________ operates at the internet layer.
A)TCP
B)IP
C)Both A and B
D)Neither A nor B

Accepted Answer

IP operates at the internet layer. TCP operates at the transport layer.
