Look Mom, no wires
Modeling for OSI
What if they see us? (public, private, or invalid, but DO NOT GO TO ANY OF THESE ADDRESSES)
100
This is typically used to connect two similar hosts to each other directly
What is Peer-to-Peer?
100
Directs frames to their proper destination using physical addresses
What is a switch?
100
This is the top OSI layer that APs operate from
What is Layer 2 (MAC Addresses matter)? They also operate in layer 1 (wireless signal to users/wired backhaul)
100
This layer is where TCP/UDP live and we refer to PDUs as segments (number and name please)
What is Layer 4 Transport?
100
192.168.254.169
What is Private?
200
This topology features connections between devices and a central hub
What is a Star Topology?
200
Used to connect networks to each other via IP
What is a Router?
200
The term we use to describe signal loss due to distance and interference
What is Attenuation?
200
The first layer that IP addresses appear in (number and name please)
What is Layer 3 Network?
200
143.256.48.32
What is Invalid?
300
This network topology consists of direct connections between all points, ensuring that no one break in signal will take a device off the whole network, very expensive and difficult to manage the wiring of.
What is a Mesh Topology?
300
Potentially detects when someone has entered your network without authorization
What is an Intrusion Detection System?
300
This type of antenna does not need to be pointed, broadcasts in all directions
What is an Omni-Directional Antenna?
300
This is the layer we interact with the most as an end user (number and name please)
What is Layer 7 Application?
300
11000000.10101000.01000100.00110010
What is private?
It is 192.168.68.50
400
This is the biggest problem with a star topology network from the perspective of reliability
What is a SPOF Single Point of Failure?
400
This is the name we give to a central computer that is primarily sending data to users
What is a Server?
400
You do this if you are experiencing issues where your wireless signal is too strong or too weak for the conditions when you are not able to relocate the AP
What is Adjust Radio Power?
400
The layer where frames are converted down into binary (number and name please)
What is Layer 1 Physical?
400
79.223.61.94
What is Public?
500
The internet (generally speaking) is this type of network topology
What is a partial mesh topology?
500
This is the name typically given to a users' relationship to a central computer, you could say this user is receiving a service
What is a Client?
500
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?
500
This is the point in the OSI model where MAC addresses come into play (number and name please)
What is Layer 2 Data Link?
500
173.16.32.64
What is Public?
600
A SOHO, an Enterprise network (within one building), and a Datacenter can all be referred to as this type of network
What is a LAN?
600
Contains no internal logic, only serves to replicate data across multiple ports with no controls in place
What is a Hub?
600
Your workplace has lunch shifts and you notice that you have a large amount of tickets for wireless connection issues during this time, and you move your access point from where it is because you discovered this source of temporary interference
What is a microwave? (walkie talkies, cordless phones, bluetooth devices can cause this interference as well, but would be much more consistent.
600
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?
600
169.252.255.254
What is Public?
