Topologies
This is typically used to connect two similar hosts to each other directly
What is Peer-to-Peer?
Directs frames to their proper destination using physical addresses
What is a switch?
These are the devices combined into a SOHO router that are commonly separate devices in an enterprise network (name three things, minimum)
What is Router/Switch/Modem/Wireless Access Point/Firewall/DHCP Server?
The layer where frames are converted down into binary (number and name please)
What is Layer 1 Physical?
This is the first thing you should do when troubleshooting after you have implemented a solution
What is Verify the Solution?
This topology features connections between devices and a central hub
What is a Star Topology?
Used to connect networks to each other via IP
What is a Router?
The term we use to describe signal loss due to distance and interference
What is Attenuation?
This is the point in the OSI model where MAC addresses come into play (number and name please)
What is Layer 2 Data Link?
Fred just tried a theory he had to solve an issue and it didn't work, but Fred feels like he has more he can do, so he did this after that theory failed to work out
What is Establish a Theory of Probable Cause?
This topology consists of connections between all points, adding redundant links in case of failure
What is a Mesh Topology?
Detects when someone has entered your network without authorization
What is an Intrusion Detection System?
This type of antenna does not need to be pointed, broadcasts in all directions
What is an Omni-Directional Antenna?
The first layer that IP addresses appear in (number and name please)
What is Layer 3 Network?
You do this so that next time the same issues comes up, you or someone else in your organization has some idea of things to try and what has happened with that issue in the past
What is Document Findings, actions, and outcomes?
This topology is one of the earliest types, one of the drawbacks was that end of the cables needed to have special terminators to reduce reflections in the wire.
What is a Bus Topology?
This is the name we give to a central computer that is primarily sending data to users
What is a Server?
You do this if you are experiencing issues where your wireless signal is too strong or too weak for the conditions
What is Adjust Radio Power?
This layer is where TCP/UDP live and we refer to PDUs as segments (number and name please)
What is Layer 4 Transport?
Jim did this before establishing a plan of action to troubleshoot a situation
What is Test the Theory to determine cause?
One of the oldest and least used topologies today, this consists of a single loop of cable passing through every network host; the entire network will lose connectivity if any part of the loop is broken.
What is a Ring topology?
This is the name typically given to users relationships to a central computer, you could say this person is receiving a service
What is a Client?
The OSI Model Mnemonic is Please Do Not Throw Sausage Pizza Away and stands for this
What is Physical, Data Link, Network, Transport, Session, Presentation, Application?
This is the layer we interact with the most as an end user (number and name please)
What is Layer 7 Application?
These are the troubleshooting steps as CompTIA will test us on, in this order
What is Identify the Problem, Establish a Theory, Test the Theory, Establish Plan of Action, Implement the Solution, Verify the Solution, and Document Findings, Actions, and Outcomes?
