Troubleshooting and the Future of Networking Flashcards
The concept and technological approach of accessing data, using applications, storing files, etc. from anywhere in the world as long as you have an internet connection
CLOUD COMPUTING
The ability for a protocol or program to determine that something went wrong
ERROR DETECTION
The ability for a protocol or program to attempt to fix an error
ERROR RECOVERY
20-bit field that’s used in conjunction with the traffic class field for routers to make decisions about the quality of service level for a specific datagram
FLOW LABEL FIELD
An 8-bit field that’s identical in purpose to the TTL field in an IPv4 header
HOP LIMIT FIELD
A flat file that contains, on each line, a network address followed by the host name it can be referred to as
HOST FILE
Used to describe situations where companies might run things like their most sensitive proprietary technologies on a Private Cloud, while trusting their less sensitive servers to a Public Cloud
HYBRID CLOUD
A piece of software that runs and manages virtual machines while also offering guests a virtual operating platform that’s indistinguishable from actual hardware
HYPERVISOR
Internet control message protocol is used by routers or remote hosts to communicate error messages when network problems prevent delivery of IP packets
ICMP
Piece of the ICMP packet which lets the recipient of the message know which of their transmissions caused the error being reported
ICMP PAYLOAD
A subset of cloud computing where a network and servers are provided for customers to run their services
INFRASTRUCTURE AS A SERVICE (IaaS)
Companies that provide IPv6 tunneling endpoints for you, so you don’t have to introduce additional equipment to your network
IPV6 TUNNEL BROKERS
Pathway on either end of a connection that takes incoming IPv6 traffic and encapsulate it within traditional IPv4 datagrams
IPV6 TUNNEL
Allow for local network segment communications and are configured based upon a host’s MAC address
LINK-LOCAL UNICAST ADDRESS
An IP address that always points to itself. This type of address is used to test internal pathing through the TCP/IP protocols
LOOPBACK ADDRESS
A way of addressing groups of hosts all at once
MULTICAST
Defines what kind of header is immediately after this current one
NEXT HEADER FIELD
16-bit field that defines how long the data payload section of the datagram is
PAYLOAD LENGTH FIELD
A subset of cloud computing where a platform is provided for customers to run their services
PLATFORM AS A SERVICE
When a company owns the services and the rest of the cloud infrastructure, whether on-site or in a remote data center
PRIVATE CLOUD
The cloud services provided by a third party
PUBLIC CLOUD
Name servers specifically set up so that anyone can use them for free
PUBLIC DNS SERVERS
An organization responsible for assigning individual domain names to other organizations or individuals
REGISTRAR
A way of licensing the use of software to others while keeping that software centrally hosted and managed
SOFTWARE AS A SERVICE (SaaS)
An 8-bit field that defines the type of traffic contained within the IP datagram and allows for different priorities
TRAFFIC CLASS FIELD
First field in an IP header that specifies the version of IP
VERSION FIELD
A single physical machine called a host, runs many individual virtual instances called guests
VIRTUALIZATION
