CompTIA A+ Exam 220-1101 - Cabling Quiz 1 Flashcards
Which refer(s) to the characteristic feature(s) of Category 5 (Cat 5) cabling?
100 Mbps transfer rate over 2 pairs of cables
1 Gbps transfer rate over all 4 pairs of cables
100-meter cable segment length
Twisted-pair copper cabling
RJ45 connector
What is the common minimum requirement for twisted-pair copper cabling in modern Ethernet networks?
Cat 5e
Which refer(s) to the characteristic feature(s) of Category 5e (Cat 5e) cabling?
1 Gbps transfer rate over all 4 pairs of cables
100-meter cable segment length
Twisted-pair copper cabling
RJ45 connector
What is the minimum cabling requirement for a 10 Gbps Ethernet connection over copper twisted pair?
Cat 6
In 10GBASE-T networks, Category 6 (Cat 6) UTP cabling supports a 10 Gbps data transfer rate at a limited range of 33-55 meters, whereas Cat 6A (Augmented) cabling allows for 10 Gbps data transfer rate over a cable segment length of 100 meters.
TRUE / FALSE
TRUE
Which refer(s) to coaxial cabling?
Used for carrying cable television signal
Copper cabling
Provides protection against EMI
Used for broadband cable Internet access
The general feature of all twisted-pair cabling types is that wires inside the cable are grouped into pairs and wires in each pair are twisted around each other to reduce signal interference from adjacent wire pairs (effect known as crosstalk).
TRUE / FALSE
TRUE
The main difference between the UTP and STP cabling is that the UTP cable takes advantage of additional protective cover reducing signal interference from outside sources.
TRUE / FALSE
FALSE
An Ethernet network cable segment implemented with the use of twisted-pair copper cabling typically covers a maximum distance of:
100 meters
Which refers to a cabling type suitable for installation under ground level without any additional protective covering?
DBC
Direct Burial Cables
Shielded Twisted-Pair (STP) cabling reduces what kind of interference?
Crosstalk
EMI
Which refer(s) to UTP cabling?
Twisted-pair copper cabling
Used in Ethernet networks and telephone systems
Low cost and ease of installation
Not surrounded by any shielding
In Ethernet networks, installed with RJ45 connector type
A type of enclosed space in a building (such as the one between a dropped ceiling and the structural ceiling) used for air handling is commonly referred to as a plenum space. A special type of cabling with fire-retardant jacket placed inside that space is known as a plenum-rated cabling. Materials from which the plenum-rated cable’s cover is made include low-smoke Polyvinyl Chloride (PVC) and Fluorinated Ethylene Polymer (FEP).
TRUE / FALSE
TRUE
What are the characteristic traits of single-mode fiber optics?
More expensive than multimode fiber optics
Transmission distances of up to 100 km
Uses laser as the source of light
Which refers to the characteristics of multimode fiber optics?
Less expensive than single-mode fiber optics
Transmission distances of up to 2 km
Uses LED as the source of light
