Ethernet Concepts
The Amount of time, including delays, for data to travel from one given point to another.
This forwards all traffic to a specific direction when there is not a match in the routing table
What is Default Route?
an IPv4 and IPv6 testing utility that uses ICMP echo request and echo reply messages to test connectivity between hosts and provides a summary that includes the success rate and average round-trip time to the destination.
What is Ping?
responsible for logical communications between applications running on different hosts and the link between the application layer and the lower layers that are responsible for network transmission.
What is the Transport Layer?
This includes poor handling of key electrical components (electrostatic discharge), lack of critical spare parts, poor cabling, and poor labeling.
What is maintenace threats?
Base two numbering system that consists of the numbers 0 and 1, called bits.
What is Binary?
These routes are automatically added by the router, provided the interface is active and has addressing
These should have a predictable static IP address
provides the basic functions for delivering datagrams between the appropriate applications, with very little overhead and data checking.
What is User datagram protocol? (UDP)
This includes temperature extremes (too hot or too cold) or humidity extremes (too wet or too dry).
Identifies the virtual connections between devices using device interfaces and IP addressing schemes
These are the routes the router does not have a direct connection and may be learned:
Manually - with a static route
Dynamically - by using a routing protocol to have the routers share their informatoin with each other
What is Remote?
Uniquely identifies an interface on an IPv6-enabled device
What is Unicast?
provides the interface between the applications used to communicate, and the underlying network over which messages are transmitted.
What is the Application Layer?
This includes physical damage to servers, routers, switches, cabling plant, and workstations.
What is Hardware Threats?
(IEEE 802.3, 802.11, or 802.15) Responsible for data encapsulation and media access control, and provides data link layer addressing
What is MAC Sublayer?
•It must have an IP address in the same range as the rest of the LAN.
•It can accept data from the LAN and is capable of forwarding traffic off of the LAN.
•It can route to other networks.
What is features of a default gateway?
a utility that is used to test the path between two hosts and provide a list of hops that were successfully reached along that path.
What is Traceroute or Tracert?
two or more computers are connected via a network and can share resources (such as printers and files) without having a dedicated server.
What is a peer-to-peer network? (P2P)
This includes voltage spikes, insufficient supply voltage (brownouts), unconditioned power (noise), and total power loss.
What is Electrical Threats?
