CP1402 Mid-Semester Exam 2024/2025
fully solved & updated
Servers that have a NOS installed require less memory, processing power, and
storage capacity than clients because servers are called on to handle only light
processing loads and requests from multiple clients. - ANSWER-False - there
require more
Ethernet performs error correction. - ANSWER-False - detection
Transport layer protocols are generally implemented directly in hardware -
ANSWER-False
When a repeater boosts a signal, any noise which has affected the signal will also
be boosted - ANSWER-True
Because digital signals do not depend on amplitude or frequency differences to
communicate information, they are more vulnerable to EMI noise - ANSWER-
False
Ethernet performs error detection - ANSWER-True
Digital signals vary continuously, while analog signals consist of discrete pulses
- ANSWER-False - other way around
Hubs are considered to be legacy equipment and their use in modern Ethernet
LANs is rare - ANSWER-True
The fundamental difference between a switch and a router is that a switch
belongs only to its local network and a router belongs to two or more local
networks. - ANSWER-True
, After a problem and its symptoms have been identified, a theory regarding a
probable cause should be established. - ANSWER-True
Application layer services are generally provided by the operating system, rather
than implemented directly in hardware - ANSWER-True
The TIA/EIA standard for wall jacks in a work area require that at least one outlet
be provided for data and one for voice - ANSWER-True
Web browsing requires a different network protocol from what is used for email -
ANSWER-False
In a straight-through cable, both RJ-45 plugs should be terminated identically. -
ANSWER-True
Each type of cable has a prescribed bend radius, which is the radius of the
maximum arc into which you can
loop a cable without impairing data transmission - ANSWER-True
Switches are considered to be legacy equipment, and their use in modern
Ethernet LANs is rare - ANSWER-False
The protocol data unit for the Physical layer of the OSI model is payload, or data -
ANSWER-False - called bits (payload or data is layer 5,6,7)
Ethernet exists at which layers of the OSI model? - ANSWER-Layer 1 & 2
What component of enterprise level structured cabling serves as the location
where an incoming network
interface enters a building and connects with the building's backbone cabling? -
ANSWER-entrance facility
The header of an Ethernet frame - ANSWER-provides the MAC address of the
source and destination nodes
Which method of transmission allows signals to travel in both directions over a
medium simultaneously? - ANSWER-full duplex
In fibre-optic terminology, SMF stands for - ANSWER-single-mode fibre
