What address is assigned to a computer that fails to locate a DHCP server? NAT MAC APIPA CIDR
APIPA
What command is used to test network connectivity between two hosts? Ipconfig Ping Netsh Nslookup
Ping
IPv6 Addresses are expressed in: hexadecimal decimal octal binary
hexadecimal
What command-line tool can be used to display and configure a network adapter? ipconfig netstat nslookup ping
ipconfig
What command-line command can be used to explore and diagnose DNS server access and functionality? ipconfig netstat tracert nslookup
nslookup
IPv4 network addresses are composed of two parts. Select the two parts from the list below. Network identifier Host identifier Route identifier MAC identifier
Network identifier
Host identifier
CIDR
used to avoid assigning entire addresses of a particular class to networks that didn’t have that many hosts
A __________ is a device that connects one network to another.
Router
layer of the OSI model that are part of the Media Access Control addresses
Data-link
Protocols
languages that all computer understand
OSI Layers
Physical, Data-link, Network, Transport, Session, Presentation, Application.
UTP
Unshielded Twisted Pair: Ethernet cable used for networking computers.
the header and footer surrounding data packets
frame
data encapsulation
the process of applying frames to data packets
Media Access Control (MAC) address
The hardcoded address on each network interface adapter on a computer.
TCP
Transmission Control Protocol
IP
Internet protocol
TCP/IP
The protocols windows use by default at the network and transport layers.
A device that connects one network to another.
Router
IP Address
An address that identifies a computer in a network, consists of a network and host indentifier.
Subnet Mask
The division between network and host identifier.
Link Local Multicast Name Resolution (LLMNR)
For computer with link-local addresses, which might not have access to a DNS server - an IPV6 name resolution option.
stateless address autoconfiguration
enables computers to configure their own addresses after transmitting router solicitation multicasts to the routers on the network and receiving router advertisement messages in return
datagram
transport layer data, encapsulated within an IP packet
connection-oriented protocol
a protocol in which two communicating systems establish a connection before they transmit any data
connectionless protocol
does not require the establishment of a connection, nor does it perform error detection or correction.
ports
codes that identify specific applications running on the system
socket
the combination of an IP address and a port number
firewall
a software routine that acts as a virtual barrier between a computer and the network to which it is attached.
NAT
a feature built into many routers that takes the packets destined for the Internet that are generated by the computers on a private network, substitutes a registered address for the computer’s private address, and then forwards the packets to the Internet distination.
8P8C connectors
the connectors on the end of RJ45 cables
packet switching networks
Local area networks are sometimes referred to as this.
