Practice: Cables and Connectors

A school is installing network cabling in a building where electrical interference from HVAC equipment is a known issue. Which cable type is most appropriate?

• Cat5e UTP, because it supports Gigabit speeds

• Cat7 UTP, because it has the highest bandwidth rating

• Cat6a UTP, because it supports 10 Gbps at 100 meters

• Cat6 STP, because shielding reduces electromagnetic interference

A technician needs to connect two switches together without a router. Which cable wiring configuration should be used?

• Crossover, because it swaps the transmit and receive pairs

• Straight-through, because both devices use the same pin layout

• Rollover, because it reverses all eight pins for console access

• T568A, because it is the commercial wiring standard

A technician is running cable in a new data center that requires 10 Gbps speeds up to 100 meters. Which cable category meets this requirement at the lowest cost?

• Cat8, rated for 40 Gbps at 30 meters

• Cat6, rated for 10 Gbps at 55 meters

• Cat5e, rated for 1 Gbps at 100 meters

• Cat6a, rated for 10 Gbps at 100 meters

A fiber optic cable run must span 40 kilometers between two buildings. Which TWO characteristics describe the correct fiber type for this application?

• Multi-mode fiber, which uses a larger core and LED light source

• Single-mode fiber, which uses a smaller core and a laser light source

• Supports long-distance transmission with less signal loss than MMF

• Limited to distances under 2 kilometers for reliable signal quality

A network administrator is setting up a console connection to configure a new router directly from a laptop. Which cable type should be used?

• Straight-through, to connect the laptop NIC to the router port

• Crossover, to match transmit and receive pairs between devices

• Coaxial, to carry the configuration signal without interference

• Rollover, to connect the laptop serial port to the router console port

A home installer needs to connect a cable modem to a wall outlet that carries a cable TV signal. Which connector type will they most likely use?

• F-type, a threaded coaxial connector used for cable and satellite TV

• ST, a bayonet-style fiber connector used in older networks

• LC, a small form-factor fiber connector used in data centers

• BNC, a bayonet-style connector used for RG-59 in video surveillance

A student wants to connect a laptop to a 4K display and stream video at 60 Hz. Which HDMI version is the minimum required to support this?

• HDMI 1.4, which supports 4K at 60 Hz with compression

• HDMI 1.4, which supports 4K at 30 Hz

• HDMI 2.0, which supports 4K at 60 Hz

• HDMI 2.1, which supports 4K at 120 Hz only

Select all that apply: Which of the following statements correctly describe DVI connector types?

• DVI-A carries an analog signal only

• DVI-I carries both analog and digital signals

• DVI-A carries both analog and digital signals

• DVI-D carries a digital signal only

A video editor connects an older monitor that uses a VGA port to a new desktop that only has DisplayPort outputs. Which statement best describes VGA compared to DisplayPort?

• VGA transmits an analog signal; DisplayPort transmits a digital signal

• VGA transmits a digital signal; DisplayPort transmits an analog signal

• Both VGA and DisplayPort transmit digital signals at different resolutions

• Both VGA and DisplayPort transmit analog signals but at different refresh rates

A technician needs to transfer large video files from an external hard drive as fast as possible. The drive uses a USB 3.2 Gen 2x2 port. What is the maximum transfer speed available?

• 5 Gbps

• 40 Gbps

• 20 Gbps

• 10 Gbps
