Protocols
This protocol does not guarantee reliable delivery of packets
What is UDP?
Routers use this information to determine the optimal path for packet forwarding.
What is a Routing Table?
Used to identify a specific process to which an internet or other network message is to be forwarded when it arrives at a server.
What is a port number?
Test the reachability of a host on a network and measure the round-trip time for packets to travel to the destination and back.
What is ping?
Larger Address Space, Improved Performance, Simplified header, Enhanced Security features
What are advantages of IPv6?
This protocol translates domain names into IP addresses.
What is DNS?
Example of a link-state routing protocol.
What is OSPF?
A method used to establish a connection between a client and a server in TCP/IP communication.
What is a Three-way Handshake?
Gives info about hops (routers) along the path
What is tracert?
A hidden or separate entry point into a computer system.
What is a backdoor?
This protocol allows a user download, upload, and transfer files from one location to another on the Internet and between computer systems.
What is FTP?
Used when there is no specific routing information available for a destination outside the local network.
What is the default gateway?
Used to track the order of of transmitted data segments to ensure that all data is received error free.
What are Sequence Numbers?
Display network configuration information, such as IP addresses, subnet masks, and network interfaces.
What is ipconfig/ifconfig?
An attack where a perpetrator gets in the middle of communication to eavesdrop or impersonate.
What is Man-in-the-Middle Attack?
These types of protocol determines the best route for data packets based on distance.
What are distance vector routing protocols?
The source and destination devices are on different networks or subnets.
What is indirect packet delivery?
Combining multiple data streams from different applications into a single connection.
What is Multiplexing?
Query DNS servers to obtain domain name or IP address information.
FE80::/10.
Used for communication within the local network segment.
What is the link-local address?
This protocol is used to virtually access network devices.
What is Telnet?
Configured manually by Administrators. Remain unchanged unless modified by the administrator
What is a Static Route?
Adjusts the amount of data sent based on the receiver's window size.
What is a sliding window?
Display network connections, routing tables, interface statistics, and other network-related information
What is netstat?
Adds an extra layer of security to an organization's internal local-area network from untrusted traffic
What is a DMZ?
