Introduction To Networks (Chapter 3 and 4 Exam)

What three layers of the OSI model are comparable in function to the application layer of the TCP/IP model?

APPLICATION, SESSION, & PRESENTATION

What type of communication will send a message to all devices on a local area network?

BROADCAST

What type of communication is sent from one computer on a network to another specific computer on the same network?

Communication protocols

Governed by IEEE 802.11, which method of contention based access does this form of wireless communication utilize?

Cooperation with CSMA/CA IN IEEE 802 Legacy System

Which address does a NIC use when deciding whether to accept a frame?

DESTINATION MAC ADDRESS

What application layer protocols are part of the TCP/IP protocol suite?

DHCP, DNS, & FTP

A network technician has recently installed new wiring in a room with fluorescent lights and electrical compressors. Which two factors may interfere with the copper cabling and result in signal distortion and data corruption?

EMI & RFI

What is the process used to place one message inside another message for transfer from the source to the destination?

ENCAPSULATION

What two fields are contained in the trailer of the data?

Error detection & Frame Stop

What method can be used by two computers to ensure that packets are not dropped because of too much data being sent too quickly?

FLOW CONTROL

Which PDU format is used when bits are received from the network medium by the NIC of a host?

FRAME

Which method of data transfer provides for the ability to send and receive data, but not at the same time?

Half-Duplex

Which WAN topology contains a central site that interconnects with branch sites using point to point links?

Hub & Spoke Topology

Which standard governs the technology known as Wi-Fi?

IEEE 802.11

At which layer of the OSI model would a physical address be encapsulated?

NETWORK LAYER

What are proprietary protocols?

PROTOCOLS DEVELOP BY ORANIZATIONS WHO HAVE CONTROL OVER THEIR DEFINITION AND OPERATION

What are three common physical WAN topologies?

Point-to-point, hub & spoke, and full mesh topology

Which type of connector does a network interface card use?

RJ-45

What will happen if the default gateway address is incorrectly configured on a host?

THE HOST CANNOT COMMUNICATE WITH HOST IN OTHER NETWORKS

What is meant by the term full-duplex?

The capacity to send and receive signals at the same time on the same medium

Why are two strands of fiber used for a single fiber optic connection?

They allow for full-duplex connectivity

What two protocols can be found at the transport layer of the TCP/IP protocol suite?

User Datagram Protocol & Transmission Control Protocol

What is the LAN topology where all end systems are chained to each other and terminated on each end?

bus topology

Which layer of the OSI model is responsible for specifying the encapsulation method used for specific types of media?

data link

What is the indicated by the term bandwidth?

indicates the capacity of a medium to carry data and it is typically measured in kilobits per second (kb/s) or megabits per second (Mb/s).

Which LAN topology was used in the legacy FDDI networks?

ring topology

What is crosstalk?

the distortion of the transmitted messages from signals carried in adjacent wires

What is indicated by the term throughput?

the measure of the bits transferred across the media over a given period of time

What are the two sub-layers of the data-link layer in the OSI model?

the media access control (MAC) layer and the logical link control (LLC) layer
