100-150 Question 101

Single answer

A network technician is tasked with setting up a high-speed backbone connection between two buildings in a campus environment. The distance between the buildings is approximately 300 meters, and the connection must be resilient to electromagnetic interference (EMI). Which cable type and connector combination is the most appropriate for this scenario?

A
Twisted pair cable with RJ-45 connectors
B
Copper coaxial cable with BNC connectors
C
Fiber optic cable with LC connectors
D
Twisted pair cable with RJ-11 connectors

Show answer and explanation

Correct answer: C

Explanation

The scenario requires a high-speed connection over a distance of 300 meters with resilience to electromagnetic interference. Fiber optic cable is the best choice for long-distance, high-speed communication as it is immune to EMI and can easily support the required distance. LC connectors are commonly used in fiber optic installations, making this the correct option.

A. Incorrect.
Twisted pair cable with RJ-45 connectors is commonly used for shorter Ethernet connections (up to 100 meters) and is susceptible to EMI, making it unsuitable for this scenario.
B. Incorrect.
Copper coaxial cable with BNC connectors can handle longer distances than twisted pair but is still vulnerable to EMI and does not support the high speeds typically required for backbone connections.
C. Correct.
Fiber optic cable with LC connectors is ideal for high-speed connections over long distances (beyond 100 meters) and is immune to EMI, making it the most appropriate choice for this scenario.
D. Incorrect.
Twisted pair cable with RJ-11 connectors is used primarily for telephone lines and cannot support the high speeds or distances required for this application.

100-150 Question 102

Single answer

A network technician is tasked with connecting a desktop computer to a network switch located 15 meters away in an office environment. The connection must support Gigabit Ethernet speeds, and the cable should be cost-effective and easy to terminate on-site. Which cable and connector type should the technician use?

A
Fiber optic cable with LC connectors
B
Twisted pair copper cable with RJ-45 connectors
C
Coaxial cable with BNC connectors
D
Twisted pair copper cable with RJ-11 connectors

Show answer and explanation

Correct answer: B

Explanation

Twisted pair copper cables, such as Cat5e or Cat6, paired with RJ-45 connectors, are commonly used for Ethernet networking in office environments due to their cost-effectiveness, ease of installation, and ability to support Gigabit speeds over short to medium distances. This makes them the ideal choice for the given scenario.

A. Incorrect.
Fiber optic cable with LC connectors is capable of supporting high data transfer speeds, but it is more expensive and typically used for longer distances or high-performance applications. It is not necessary for a 15-meter office connection.
B. Correct.
Twisted pair copper cable with RJ-45 connectors is a cost-effective and commonly used solution for Gigabit Ethernet connections in office environments. It is suitable for the 15-meter distance and supports the required speed.
C. Incorrect.
Coaxial cable with BNC connectors is not used for Ethernet networking in modern office environments. It is more common in legacy systems or specialized applications like CCTV.
D. Incorrect.
Twisted pair copper cable with RJ-11 connectors is used for telephone lines and is not suitable for Ethernet networking or Gigabit speeds.

100-150 Question 103

Single answer

A network technician is tasked with connecting a new desktop computer to the office network. The computer will be placed 10 meters away from the nearest network switch. The technician needs to use a cable and connector type suitable for this distance and the RJ-45 port available on both the desktop and the switch. Which combination of cable and connector should the technician use?

A
Twisted pair cable with RJ-45 connectors
B
Fiber optic cable with SC connectors
C
Coaxial cable with RJ-11 connectors
D
Twisted pair cable with RJ-11 connectors

Show answer and explanation

Correct answer: A

Explanation

For a short distance of 10 meters, twisted pair cables (such as Cat5e or Cat6) with RJ-45 connectors are the most appropriate choice for connecting a computer to a switch. They are cost-effective, widely available, and support Ethernet standards commonly used in office networks. Other cable and connector combinations, such as fiber optic or coaxial with RJ-11, are either unnecessary or incompatible for this scenario.

A. Correct.
Twisted pair cables with RJ-45 connectors are commonly used for Ethernet connections in networks within short to medium distances, such as 10 meters, and they are compatible with RJ-45 ports.
B. Incorrect.
Fiber optic cables with SC connectors are used for high-speed data transmission over longer distances, typically beyond 100 meters, making them unnecessary for this scenario.
C. Incorrect.
Coaxial cables are used in specific applications like cable internet and do not use RJ-11 connectors. RJ-11 connectors are typically used for telephone lines, not Ethernet connections.
D. Incorrect.
RJ-11 connectors are designed for telephone networks and are incompatible with RJ-45 ports on network devices. Twisted pair cables with RJ-11 connectors would not work for Ethernet connections.

100-150 Question 104

Single answer

A network technician is tasked with connecting a desktop computer to a network switch located in a different room. The technician needs to use a cable that minimizes signal interference and connects to an RJ-45 port on both the desktop and the switch. Which type of cable should the technician use?

A
Twisted pair copper cable
B
Fiber optic cable
C
Coaxial cable
D
RJ-11 cable

Show answer and explanation

Correct answer: A

Explanation

The correct answer is twisted pair copper cable because it is the standard cable type for Ethernet networks and is compatible with RJ-45 connectors. It is designed to reduce signal interference, making it suitable for connecting network devices over moderate distances.

A. Correct.
Twisted pair copper cable, such as Cat5e or Cat6, is commonly used for Ethernet connections and connects to RJ-45 ports. It also minimizes signal interference due to its twisted pair design.
B. Incorrect.
Fiber optic cable is used for high-speed and long-distance connections, but it does not connect to RJ-45 ports. It uses specialized fiber connectors like LC or SC.
C. Incorrect.
Coaxial cable is primarily used for cable television or broadband internet connections and does not connect to RJ-45 ports.
D. Incorrect.
RJ-11 cable is used for telephone connections and does not support Ethernet networking or RJ-45 ports.

100-150 Question 105

Single answer

A network technician is tasked with setting up a high-speed connection between two buildings on a corporate campus. The connection must span 500 meters and avoid interference from nearby electrical equipment. Which cable and connector types should the technician use to meet these requirements?

A
Twisted pair cable with RJ-45 connectors
B
Copper coaxial cable with BNC connectors
C
Fiber optic cable with LC connectors
D
Twisted pair cable with RJ-11 connectors

Show answer and explanation

Correct answer: C

Explanation

In this scenario, the connection must span 500 meters and avoid interference from nearby electrical equipment. Fiber optic cables with LC connectors are the best choice because they support high-speed data transmission over long distances and are immune to electromagnetic interference. Copper-based solutions, such as twisted pair or coaxial cables, are either limited by distance or prone to interference, making them unsuitable for this requirement.

A. Incorrect.
Twisted pair cables, such as Cat5e or Cat6, are commonly used for Ethernet connections but are limited to a maximum distance of 100 meters and are susceptible to electromagnetic interference (EMI). This does not meet the 500-meter requirement.
B. Incorrect.
Copper coaxial cables can handle longer distances than twisted pair, but they are still susceptible to EMI and are not ideal for high-speed connections over 500 meters.
C. Correct.
Fiber optic cables are the best choice for high-speed connections over long distances (up to kilometers, depending on the type) and are immune to EMI. LC connectors are common in fiber optic installations, making this the most suitable option.
D. Incorrect.
RJ-11 connectors are used for telephone lines and are not designed for high-speed network connections or long distances. This option is unsuitable for the scenario.
