What is a characteristic of multicast messages?

They are sent to a select group of hosts.

They are sent to all hosts on a network.

They are sent to a single destination.

Which statement is correct about network protocols?

They define how messages are exchanged between the source and the destination.

Network protocols define the type of hardware that is used and how it is mounted in racks.

They all function in the network access layer of TCP/IP.

They are only required for exchange of messages between devices on remote networks.

What is an advantage of network devices using open standard protocols?

A client host and a server running different operating systems can successfully exchange data.

Network communications is confined to data transfers between devices from the same vendor.

Internet access can be controlled by a single ISP in each market.

Competition and innovation are limited to specific types of products.

What is the definition of bandwidth?

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

the speed at which bits travel on the network

the amount of data that can flow from one place to another in a given amount of time

the measure of usable data transferred over a given period of time

Which statement correctly describes frame encoding?

It transmits data signals along with a clock signal which occurs at evenly spaced time durations.

It uses the characteristic of one wave to modify another wave.

It generates the electrical, optical, or wireless signals that represent the binary numbers of the frame.

It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.

What is a characteristic of UTP cabling?

woven copper braid or metallic foil

A wireless LAN is being deployed inside the new one room office that is occupied by the park ranger. The office is located at the highest part of the national park. After network testing is complete, the technicians report that the wireless LAN signal is occasionally affected by some type of interference. What are two possible causes of the signal distortion? (Choose two.)

the large number of trees that surround the office

the elevated location where the wireless LAN was installed

the cellular phones that are used by the employees

the number of wireless devices that are used in the wireless LAN

What is indicated by the term throughput?

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

the guaranteed data transfer rate offered by an ISP

the capacity of a particular medium to carry data

the measure of the usable data transferred across the media

the time it takes for a message to get from sender to receiver

What is one advantage of using fiber optic cabling rather than copper cabling?

It is able to carry signals much farther than copper cabling.

It is usually cheaper than copper cabling.

It is able to be installed around sharp bends.

It is easier to terminate and install than copper cabling.

What is the purpose of the OSI physical layer?

transmitting bits across the local media

performing error detection on received frames

exchanging frames between nodes over physical network media

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

The two strands allow the data to travel for longer distances without degrading.

They prevent crosstalk from causing interference on the connection.

They increase the speed at which the data can travel.

They allow for full-duplex connectivity.

Which characteristic describes crosstalk?

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

the distortion of the network signal from fluorescent lighting

the weakening of the network signal over long cable lengths

the loss of wireless signal over excessive distance from the access point

Which procedure is used to reduce the effect of crosstalk in copper cables?

twisting opposing circuit wire pairs together

requiring proper grounding connections

wrapping the bundle of wires with metallic shielding

designing a cable infrastructure to avoid crosstalk interference

avoiding sharp bends during installation

A network administrator is measuring the transfer of bits across the company backbone for a mission critical financial application. The administrator notices that the network throughput appears slower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)

the latency that is created by the number of network devices that the data is crossing

the type of traffic that is crossing the network

the amount of traffic that is currently crossing the network

the sophistication of the encapsulation method applied to the data

the bandwidth of the WAN connection to the Internet

What are two characteristics of fiber-optic cable? (Choose two.)

It is not affected by EMI or RFI.

It combines the technique of cancellation, shielding, and twisting to protect data.

Each pair of cables is wrapped in metallic foil.

It typically contains 4 pairs of fiber-optic wires.

It is more expensive than UTP cabling is.

What is a primary role of the Physical layer in transmitting data on the network?

create the signals that represent the bits in each frame onto the media

provide physical addressing to the devices

determine the path packets take through the network

control data access to the media

With the use of unshielded twisted-pair copper wire in a network, what causes crosstalk within the cable pairs?

the magnetic field around the adjacent pairs of wire

the use of braided wire to shield the adjacent wire pairs

the reflection of the electrical wave back from the far end of the cable

the collision caused by two nodes trying to use the media simultaneously

Which two statements describe the services provided by the data link layer? (Choose two.)

It provides reliable delivery through link establishment and flow control.

It manages the access of frames to the network media.

It defines the end-to-end delivery addressing scheme.

It maintains the path between the source and destination devices during the data transmission.

It ensures that application data will be transmitted according to the prioritization.
