CompTIA A+ Certification Core 1 (220-1101) - Cables and Connectors

The video tutorial covers the fundamentals of networking cables and connectors, focusing on Ethernet, coaxial, twisted pair, and fiber optic cables. It explains the different types of cables, their uses, and the importance of cat and plenum ratings. The tutorial also highlights the significance of direct buried cables for outdoor installations.

What is the primary function of Ethernet in networking?

• To provide wireless connectivity

• To define network frames and cabling

• To enhance video streaming quality

• To secure network connections

Which type of connector is commonly used with RG6 coaxial cables?

• F-type

• RJ11

• BNC

• RJ45

What is the main advantage of twisted pair cables?

• They are cheaper than coaxial cables

• They reduce interference and allow longer cable runs

• They are easier to install

• They support higher data rates than fiber optics

Which connector is typically used for telephone cables?

• RJ45

• BNC

• RJ11

• F-type

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

• Multimode is faster than single mode

• Multimode is more expensive

• Single mode is used for short distances

• Multimode uses LEDs, single mode uses lasers

What is the main component of a fiber optic cable that carries the light signal?

• Fiberglass fiber

• Plastic sheath

• Metallic foil

• Copper wire

Which CAT rating supports 10 Gigabit Ethernet at 100 meters?

• CAT6A

• CAT6

• CAT5e

• CAT5

What is the purpose of plenum-rated cables?

• To improve signal quality

• To resist fire in building spaces

• To provide better data transmission

• To reduce cable costs

What is a direct buried cable designed for?

• Indoor use only

• High-speed data transmission

• Reducing electromagnetic interference

• Outdoor installations with extra protection

Why is it important to check the CAT rating when buying cables?

• To know the data transmission capacity

• To determine the cable's length

• To ensure compatibility with connectors

• To verify the cable's color
