Question 1

"A graphical or text description of the wire connections from pin to pin" defines which of the following?
A)Color-map
B)Continuity map
C)Wire-map
D)Connectivity map
E)None of these answers are correct.

Accepted Answer

A wire-map is a representation of the wire connections from pin to pin. It can be either graphical or text-based. A color-map is a visual representation of signal strength or frequency, a continuity map is a diagram of the electrical connections in a circuit, and a connectivity map is a diagram of the interconnections between parts of a network or system.

Question 2

What is another name for an RJ-45 connector?
A)8C8P
B)8W8T
C)8P8C
D)8P8T

Accepted Answer

The RJ-45 connector is also known as 8P8C, which stands for 8 positions and 8 contacts. Option A and B are not correct as they use different combination of terms not related to RJ-45 connectors. Option D is also not correct as it uses T instead of C, which stands for positions with different functions than contacts.

Question 3

The nominal velocity of propagation for UTP
A)Should be close to 1
B)Should be close to 100m
C)Is the speed of light
D)Should be some percentage of the speed of light

Accepted Answer

The nominal velocity of propagation for UTP (Unshielded Twisted Pair) should be some percentage of the speed of light. Typically, it is around 66-67% of the speed of light in vacuum.

Question 4

The main cross-connect (MC)connects to which of the following? (Choose two.)
A)Telco
B)ISP
C)Floor distributors
D)Work station outlet

Accepted Answer

The answer of The main cross-connect (MC)connects to which of...

Question 5

The RJ-48 connector uses what type of cabling?
A)Twisted pair
B)Wireless
C)MMF
D)SMF

Accepted Answer

RJ-48 connectors typically use twisted pair cabling, which consists of pairs of insulated copper wires twisted together to reduce crosstalk and electromagnetic interference. Wireless is not a viable option for a wired connector, and MMF and SMF are types of fiber optic cabling, which are not typically used with RJ-48 connectors.

Question 6

"An Ethernet system operating at 100Mbps" defines which of the following?
A)AUI Ethernet
B)Link Ethernet
C)Gigabit Ethernet
D)Fast Ethernet
E)None of these answers are correct.

Accepted Answer

Fast Ethernet operates at a speed of 100Mbps, which matches the given statement. AUI Ethernet operated at 10Mbps, Link Ethernet is not a valid Ethernet standard, and Gigabit Ethernet operates at 1Gbps, which is faster than the given speed. Therefore, the correct choice is Fast Ethernet.

Question 7

"Where the cable connects to a jack or a patch panel" defines which of the following?
A)TCO
B)Closet
C)Termination
D)None of these answers are correct.

Accepted Answer

This is the definition of termination, which refers to the point where a cable ends and connects to a physical device such as a jack or patch panel. TCO refers to total cost of ownership and closet is a room or space where networking equipment is stored, so neither of those options fit.

Question 8

The RJ-48 connector is commonly used with what type of network connections?
A)Ethernet
B)Satellite
C)Cable
D)T1 lines

Accepted Answer

The RJ-48 connector is commonly used with T1 lines.

Question 9

What are two potential problems if you create a split pair connection when you are working with a straight-through patch cable? (Choose two.)
A)Interference
B)Attenuation
C)Crosstalk
D)Short

Accepted Answer

The answer of What are two potential problems if you...

Question 10

"Another term for network congestion" defines which of the following?
A)Bottled
B)Bottlenecking
C)Constricted
D)Constricting
E)None of these answers are correct.

Accepted Answer

Bottlenecking is another term for network congestion, as the term refers to a narrow point in a system that restricts the flow of traffic.

Question 11

In the balanced mode of operation for UTP
A)The (+)side connects to ground.
B)The (-)side connects to ground.
C)Neither wire in the wire pairs connects to ground.
D)The balanced mode of operation for UTP is only used with STP cable installations.
E)The balanced mode of operation for UTP is only used in high EMI environments.

Accepted Answer

In the balanced mode of operation for UTP, neither wire in the wire pairs connects to ground. This helps reduce electromagnetic interference (EMI) and crosstalk. This mode of operation can be used in both UTP and STP cable installations and is not specifically designed for high EMI environments, although it can be helpful in those situations.

Question 12

The proper alignment of the transmit and receive pairs in a CAT5/5e/6 UTP cable requires what?
A)The transmit (+)and (-)signals connected to the receivers (+)and (-)signals,respectively.
B)The transmit (+)and (-)signals connected to the receivers (-)and (+)signals,respectively.
C)The transmit (-)and (+)signals connected to the receivers (-)and (+)signals,respectively.
D)None of these answers are correct.

Accepted Answer

The answer of The proper alignment of the transmit and...

Question 13

RG-6 and RG-59 cables are used in what type of systems? (Choose two.)
A)Satellite
B)Cable television

Question 14

"Consists of all the link elements from the wall plate to the switch" defines which of the following?
A)Complete Link
B)Full Channel
C)Full Link

Question 15

What type of terminations are found with RG-6 and RG-59 cables? (Choose two.)
A)G-type
B)RJ-10
C)F-type
D)BNC

Accepted Answer

RG-6 and RG-59 cables typically have F-type and BNC terminations. G-type and RJ-10 terminations are not commonly used with these types of cables.

Question 16

CAT 6 UTP is recommended for use in what
A)The campus network backbone cabling

"Interconnected LANs within a limited geographic area" defines which of the following?
A)Campus Network
B)Wide Area Network
C)Metropolitan Area Network
D)None of these answers are correct.

Accepted Answer

A campus network is defined as interconnected LANs within a limited geographic area, typically within a university or corporate campus. A wide area network spans over a large geographic area, while a metropolitan area network covers a larger area than a campus network but is still limited to a specific metropolitan region.
