-
network
-
mainframe
-
supercomputer
-
client
A
Correct answer
Explanation
Servers provide resources, data, or services to other computers, known as clients, over a network.
-
Common Gateway Interface(CGI)
-
Carrier
-
ColdFusion
-
Cladding
-
Collision
B
Correct answer
Explanation
This is the correct option. A continuous frequency, capable of being modulated or impressed with a second signal, is called carrier.
-
physical layer
-
data link layer
-
physical layer and data link layer
-
network layer
-
physical layer, data link layer and network layer
C
Correct answer
Explanation
This is the correct option because frame relay operates in both the physical layer and the data link layer.
-
Packet switching
-
Circuit switching
-
Message switching
-
Banyan switch
-
None of these
B
Correct answer
Explanation
This is the correct option. In circuit switching, a dedicated physical connection is established between the sending and receiving device. Before starting communication, the station must make a reservation of resources to be used during the communication. These resources remain dedicated during the entire duration of data transfer.
-
Contention
-
Carrier
-
ColdFusion
-
Decibel(dB)
-
Distortion
A
Correct answer
Explanation
This is the correct option. An access method, when two or more stations attempt to use the same channel at the same time, is called contention.
-
Device monitoring.
-
Network device performance metrics.
-
Hardware probe and distributed analyzer.
-
Permission analysis.
-
Netflow.
E
Correct answer
Explanation
This technique of measurement of a traffic network can take the the form of hardware based collectors or probes or software based collectors.
-
Tree flow
-
Lactic flow
-
Source code analysis
-
Permission analysis
-
Flow analysis
E
Correct answer
Explanation
This analysis provides insight into the flow of traffic with the network; specifically who and what of traffic consumption.

-
System monitor
-
Dataflow analysis
B
Correct answer
Explanation
This tool analyzes conversations between devices on the network from location where the analyzer is measuring.
