The Seven Layers
The seven layers of the OSI protocol model
What are: Application, Presentation, Session, Transport, Network, Data-link and Physical?
A range of IP addresses that a DHCP server can assign to clients.
What is a scope? [Also accept pool]
When browsing the web, your computer will be sending information over this common TCP/IP protocol.
This cable type uses laser light impulses, has the longest run, and is very easy to break.
What is fiber optic cable?
What are Availability, Confidentiality and Integrity?
Replacing IP Version 4 with Version 6 is a change to which layer of the OSI protocol stack?
Network Layer or Layer 3.
The 3 network addresses below have this in common.
10.0.0.0 /8
172.16.0.0 /16
192.168.42.0 /24
This is used to allow private IP addresses to use public addresses in order to remain secure.
What is Network Address Translation (NAT)?
What is RJ-45
What provides digital connection to the internet via phone lines?
What is Digital Subscriber Line (DSL)?
This protocol is ongoing at the Network/ Internet layer with host to host connection without confirmation.
What is UDP?
This Subnet mask class has values 224-239 and identifies multi-computers rather than a single host.
What is Class D?
This protocol to finds the MAC address from an IP address
What is Address Resolution Protocol (ARP)
If you have a bad NIC or cable, the link light might look like this
What is "unlit?"
This table keeps track of a network’s MAC addresses and which switch port each one is connected to.
What is the Content Addressable Memory (CAM) table?
This layer of the OSI model sets the standards for sending and receiving electrical signals between devices.
What is the physical layer?
This protocol is commonly used to check if a ip address is up or online
What is ICMP (Internet Control Messaging Protocol)? [I'll also accept "ping"].
Discover, Offer, Request, Acknowledge are the steps for a client request for this kind of network server.
What is a DHCP server?
This mode of fiber is typically used for longer distance runs despite its small core diameter
Communication that uses one channel for both sending and receiving is called Simplex. Communication that uses multiple channels for sending and receiving is called this.
Network switches work at this layer.
What is the Data-link layer (or layer 2)?
What is the APIPA network address?
what is the hop count?
This marks the boundary between telco equipment or cable and your private network
What is the demarc?
Base 16 Arithmetic
what is hexadecimal?
