Question 4

An IS used to connect two LANs that use similar LAN protocols and acts as an address filter,picking up packets from one LAN that are intended for a destination on another LAN and passing those packets on,is a ________.
A)router
B)bridge
C)broadcast
D)end system

Accepted Answer

A bridge is used to connect two LANs that use similar LAN protocols and acts as an address filter, picking up packets from one LAN that are intended for a destination on another LAN and passing those packets on. Routers connect different types of networks, not just LANs. Broadcast is a term used to describe the process of transmitting a message to all devices on a network. End system refers to any device that is connected to a network.

Question 5

The effect of the ________ is to erase the portion of the host field that refers to an actual host on a subnet,leaving the network number and the subnet number.
A)echo reply
B)checksum
C)subnet mask
D)address mask

Accepted Answer

The subnet mask is used to erase the portion of the host field that refers to an actual host on a subnet, leaving the network number and the subnet number.

Question 6

Which of the following is NOT an enhancement of IPv6 over IPv4?
A)improved error recovery
B)address autoconfiguration
C)support for resource allocation
D)expanded address space

Accepted Answer

IPv6 does not specifically enhance error recovery over IPv4. The main enhancements of IPv6 include expanded address space, address autoconfiguration, and support for resource allocation, among others. Error recovery mechanisms are generally handled at higher layers of the OSI model, not at the IP layer.

Question 7

A function performed by a receiving entity to limit the amount or rate of data that is sent by a transmitting entity is ________.
A)flow control
B)error control
C)transmission control
D)data control

Accepted Answer

Flow control is the function that enables the receiving entity to limit the amount or rate of data that is sent by a transmitting entity, helping to avoid network congestion and ensure the efficient use of network resources. Error control is focused on detecting and correcting errors that may arise during data transmission. Transmission control is not a commonly used term related to networking, and data control may refer to various aspects of data management but does not specifically address the limitation of data transmission rates.

Question 8

Starting with a 32-bit block consisting of four 8-bit fields,the ________ contains a list of one or more intermediate nodes to be visited on the way to a packet's destination.

Accepted Answer

The answer of Starting with a 32-bit block consisting of...

Question 11

The ________ is a means of uniquely identifying an end-system-originated datagram.
A)protocol layer number
B)source address
C)Data Unit Identifier
D)protocol identifier

Question 12

IPv6 allows three types of addresses: unicast,anycast,and ________.

Accepted Answer

The answer of IPv6 allows three types of addresses: unicast,anycast,and...

Question 13

The ________ primitive is used to request transmission of a data unit.
A)Send
B)Source Routing
C)Transmit
D)Request

Accepted Answer

The Send primitive is used to request the transmission of data unit in networking protocols such as TCP/IP. It initiates the transmission process and is typically used by the sending host to send data to the receiving host. Therefore, choice A is the best option.

Question 14

A device used to provide a communications path and perform the necessary relaying and routing functions so that data can be exchanged between devices attached to different networks in the internet is an ________.

Accepted Answer

The answer of A device used to provide a communications...

Question 15

An entity may transmit data to another entity in such a way that each PDU is treated independently of all prior PDUs.This is known as ________ data transfer.

Accepted Answer

The answer of An entity may transmit data to another...

Question 16

A device attached to one of the networks of an internet that is used to support end user applications or services is ________.
A)an end system
B)a router
C)a subnet
D)an intermediate system

Accepted Answer

An end system, also known as a host, is a device that is connected to one of the networks of the Internet and is used to support end user applications or services, such as web browsing or email. Routers, subnets, and intermediate systems are all network infrastructure components and are not primarily used to support end user applications or services.

Question 17

The principal feature of ________ is that it can encrypt and/or authenticate all traffic at the IP level.
A)TCP/UDP
B)IAB
C)VPN
D)IPSec

Accepted Answer

IPSec (Internet Protocol Security) is a protocol suite for securing IP communications by authenticating and encrypting each IP packet of a communication session. It can be used to establish virtual private networks (VPN) and provides end-to-end security at the IP layer, allowing for secure communication between networks or hosts.

Question 18

A hop-by-hop option that is used to send IPv6 packets with payloads longer than 65,535 octets is ________.
A)PAD1
B)fragmentation
C)jumbo payload
D)PADN

Accepted Answer

Jumbo payload is an IPv6 option that allows packets to have payloads larger than 65,535 octets. This option is used to avoid fragmentation of packets at intermediate routers and is a hop-by-hop option. PAD1 and PADN options are used for packet padding and fragmentation is not an option used for sending large payloads.

Question 19

A ________ consists of a set of computers that interconnect by means of a relatively unsecure network and makes use of encryption and special protocols to provide security.

Accepted Answer

The answer of A ________ consists of a set of...

Question 20

In IPv6 ________ may only be performed by source nodes,not by routers,along a packet's delivery path.
A)bridging
B)reassembly
C)fragmentation
D)ordered delivery

Accepted Answer

IPv6 routers are not allowed to perform fragmentation, this task is the responsibility of the source node to ensure that packets do not exceed the path MTU. This helps to reduce the processing load on intermediate routers and improves efficiency in packet forwarding.
