Section 4 - Ethernet Basics Flashcards
Ethernet is defined by which organization?
IEEE 802.3
Organize a complete frame from front to back.
Preamble -> Destination MAC -> Source MAC -> Ether (data type) -> Data -> Pad -> FCS
Frames can carry up to 1500 bytes, whereas Jumbo Frames can carry up to ___ bytes.
9000 bytes
The data in a frame that is used for error detection is called the __.
FCS (a.k.a., Frame Check Sequence)
CSMA/CD stands for:
A) Carrier Sense Managed Access / Collision Detection
B) Carrier Sense Managed Access / Cord Detection
C) Cranky Steve Must Age / Cord Discord
D) Carrier Sense Multiple Access / Collision Detection
D) Carrier Sense Multiple Access / Collision Detection
Which two network-defining categories require terminating resistors at both ends of a network segment?
10Base5
10Base2
Base requires a “T” connector.
A) 10Base5 B) 10Base2 C) 10BaseT D) A & B E) A & C
B) 10Base2
True/False:
10BaseT runs at 10 Mbps over Cat 3 or higher UTP and up to 1024 nodes.
True
An RJ-45 connector can also be referred to as an __ connector.
8P8C (8 Pin 8 Contacts)
Which cable type is created when mixing the EIA/TIA 568A and EIA/TIA 568B wiring schemes?
Crossover cable
Which cable type is created when using a single wiring scheme to terminate Unshielded Twisted Pair (UTP)?
Straight-through cable
A Switch forwards frames based on…
MAC addresses
Hubs use __ to avoid collisions.
A) CSMA/CD
B) MCSA/CD
C) CMSA/CD
A) CSMA/CD
True/False:
Hubs create and use MAC address tables to map ports and host devices.
False
True/False:
An octet also means byte and vice-versa.
True
What is the minimum amount of data an ethernet frame can carry?
64 bytes
A __ is used to fill empty byte-space in a frame.
Pad
MTU stands for Maximum ____ Unit.
Maximum Transmission Unit
Define the three values in 10BaseT.
10 = network speed in MB/s Base = type of connection; either Base or Broad T = defines the length of cable
True/False:
The Multi-station Access Unit was developed by IBM and is referred to as a Token Ring.
True
Describe the EIA/TIA 568A wiring scheme.
WGreen/Green, WOrange/Blue, WBlue/Orange, WBrown/Brown
Describe the EIA/TIA 568B wiring scheme.
WOrange/Orange, WGreen/Blue, WBlue/Green, WBrown/Brown
A collision domain is to a __, whereas a broadcast domain is to a __.
Hub
Switch
