Section 5 - Modern Ethernet Flashcards
Which signal mode allows both sides of a conversation to occur at the same time?
Full-duplex mode
100BaseT (a.k.a., 100BaseTX) runs at __ Mbps up to 100 meters.
100 Mbps
100BaseFX runs at 100 Mbps up to 2 kilometers and indicates which type of cabling?
Fiber-optic
What is a cable called that uses the same wiring scheme when terminating both ends?
Straight-through cable
What is a cable called that uses different wiring schemes when terminating both ends?
Crossover cable
When connecting two legacy switches together to make one backbone, which type of cable should be used to create the connection?
Crossover cable
1000BaseCX uses __ and runs up to 25 meters.
A) Twincx
B) Twinax
C) Twinac
B) Twinax
Which option below indicates UTP cable is being used on the network?
A) 10GBaseLR B) 1000BaseCX C) 1000BaseSX D) 1000BaseT E) 10GBaseSR F) 1000BaseLX
D) 1000BaseT
Provide all five network terms used to indicate fiber-optic cabling is being used.
1000BaseSX 1000BaseLX 10GBaseSR 10GBaseLR 10GBaseER
Provide all three network terms used to indicate UTP cabling is being used.
1000BaseT
10GBaseT
SFP and SFP+ are __ __ transceivers.
Small form-factor
What is the SFP standard designed for 40 Gbps Ethernet?
QSFP
How does a bridging loop occur?
When two or more switches are connected in a manner that creates a “loop”, or an infinite cycle.
What is the result of a bridged loop?
The entire domain goes down.
What could cause network speed degradation when bridging two or more switches?
Speed mismatch
Most modern switches have a feature that will auto detect connected hardware. What does this auto-detecting feature eliminate the need for when compared to setting up legacy switches?
Eliminates the need for crossover and uplink cable requirements.
What is an Uplink Port?
A pre-crossover port
What is an Auto-Sensing Port?
A self-configuring port that detects what type of wiring scheme is being used and what it is connecting to.
Bidirectional (a.k.a., ___) = ???
A.k.a., Bidi; different laser colors can be used for sending and receiving data.
STP stands for what? What is its purpose?
Spanning Tree Protocol; developed to avoid Bridging Loops by turning off ports.
Define Flood Guard.
A function in a Switch that prevents flooding by turning off ports.
What is Speed Mismatch and what is the result when present in two different switches?
When two Switches use different port speeds; this ultimately indicates that the hardware is incompatible and can be detected by link lights not turning on/off and the two ports being used show entirely different link speeds.
What is the Multisource Agreement (MSA)?
The collective agreement of a uniformed connector for Switches when using fiber cabling.
What type of hardware would I plug a Gbic, SFP/SFP+, or QSFP connector into?
Switch
