Understanding Network Cable Types

Which of the following cable types is most commonly used for connecting computers to networking equipment?

• Coaxial

• Twisted Pair

• Fiber Optic

• HDMI

What is the maximum transmission rate of a Cat 6 cable over a distance of 55 meters?

• 100 Mbps

• 1 Gbps

• 10 Gbps

• 100 Gbps

Explain why shielded twisted pair (STP) cables are used in certain environments over unshielded twisted pair (UTP) cables.

• STP cables are cheaper than UTP cables.

• STP cables are more flexible than UTP cables.

• STP cables reduce electrical interference.

• STP cables are lighter than UTP cables.

Which of the following is a characteristic of single-mode fiber optic cables?

• They carry multiple light paths.

• They are typically sourced by an LED.

• They have a longer transmission distance than multimode.

• They are more susceptible to electrical interference.

Compare the transmission speeds and distance limitations of Cat 5e and Cat 6a cables.

• Cat 5e has a higher transmission speed than Cat 6a.

• Cat 6a supports longer distances at higher speeds than Cat 5e.

• Both have the same transmission speed and distance limitations.

• Cat 5e supports longer distances at higher speeds than Cat 6a.

What is the primary purpose of using plenum-rated cables in network installations?

• To increase data transmission speed

• To reduce the cost of installation

• To prevent the release of toxic gases in case of fire

• To improve signal quality

Identify the correct T568B wiring sequence for RJ-45 connectors.

• Green/White, Green, Orange/White, Blue, Blue/White, Orange, Brown/White, Brown

• Orange/White, Orange, Green/White, Blue, Blue/White, Green, Brown/White, Brown

• Blue/White, Blue, Green/White, Orange, Orange/White, Green, Brown/White, Brown

• Brown/White, Brown, Blue/White, Blue, Green/White, Green, Orange/White, Orange

Discuss the advantages of using fiber optic cables over copper cables in network installations.

• Fiber optic cables are more expensive and less durable.

• Fiber optic cables are immune to electrical interference and wiretapping.

• Fiber optic cables have lower transmission speeds.

• Fiber optic cables are heavier and harder to install.

Which type of coaxial cable is commonly used for cable television?

• RG-6

• RG-59

• RG-11

• RG-8

What is the main difference between single-mode and multimode fiber optic cables?

• Single-mode carries multiple light paths, while multimode carries one.

• Single-mode is sourced by an LED, while multimode is sourced by a laser.

• Single-mode has a longer transmission distance than multimode.

• Single-mode is more flexible than multimode.
