Port 53
If multiple routers broadcast on the same ________, there will be interference and poor signals are the result.
Channels
These are the speeds you can tell your customer to expect when they move from DSL to T1.
A/DSL up to 8mb/s, typically ~4mb/s
T1 1.544 up and 1.544 down.
This device separates collision domains.
Double points to explain collision domains.
Switch
This is the difference between UTP, STP, TCP, and UDP.
UTP - unshielded twisted pair.
STP - shielded twisted pair.
TCP - transmission control protocol.
UDP - user datagram protocol.

This is the feature that allows multiple private addresses to communicate on a single public address.
NAT (Static/Dynamic NAT are also acceptable)
A customer stating they have a "56k connection" identifies this.
Dial up
This device separates broadcast domains.
Double points to explain broadcast domains.
Coax cable is most often terminated with one of these.
F-connector
These are the definitions of both PoE and and a repeater/extender.
PoE is power over ethernet, provides volts to run devices over ethernet cabling.
Repeaters/Extenders repeat signals near the max length of signal range to generate a clean signal for at least that much range again.
This is a super insecure feature that should never be used, but was intended to automatically configure firewall/access rules to allow a connected device through.
UPnP
This is the speed of DOCSIS 2.0, 3.0, and 3.1 (ballpark)
2.0 - 38
3.0 - 150
3.1 - 10gb/s
These are two devices that decide to forward or filter packets based on mac or administratively defined rules.
Double points to explain which is which and their decision making process.
Bridge, firewall
For double points, bridges forward or filter if the mac is on the other side. Firewalls forward or filter based on user defined rules.
These are the three types of connectors for fiberoptics.
ST, SC, LC
These are the six troubleshooting steps in order.
1.Identify the problem
2.Establish a theory
3.Test the theory
4.Implement a plan
5.Verify resolution
6.Document findings
This is the feature that is used to ensure some traffic types (like skype, netflix streaming) are prioritized over other traffic types (emails, webpages)
QoS (Quality of Service)
New construction has interrupted a companies internet connection. This is the type of connection that they most likely had.
LOS (Line of Sight)
This device is often found in racks where cables are terminated by punch down on one side to simplify changeable connections on the other.
patch panel
This is the difference between single and multi mode fiberoptic cables.
Single Mode: long distance & single beam of light
Multi Mode: short distance & multiple beams of light
These are the 5 motherboard form factors in order from smallest to largest.
