ExamCompass: Network+ Practice Exam 8
PAT
A Network Address Translation (NAT) method that binds a combination of private IP address and port number with a corresponding public IP address and port information
ipconfig /all
A command-line command used to display MAC address in MS Windows
TTL
A field in an IP datagram that specifies how many more hops a packet can travel before being discarded
Static route
A manually-configured routing entry
CSMA
A network protocol providing means for controlling access to a transmission medium
Routing table
A set of rules stored on a Layer 3 switch or a networked host that allows to determine the topology of the surrounding network
collision
A situation in which two or more demands are made simultaneously on equipment that can handle only one at any given moment
Multicast
A type of network traffic intended for a particular group of hosts
Unicast
A type of network traffic intended for a single host identified by a unique IP address
Hard-coded into a NIC 48-bit hexadecimal number Physical address
Characteristic features of a MAC address
route print netstat -r
Command-line commands in MS Windows which are used to display the contents of a routing table
ifconfig
Commands used to display MAC address in Linux
Router
Device used for separating broadcast domains
IP to MAC
Kind of resolution provided by Address Resolution Protocol (ARP)
Smurf attack
Network attack type which exploits broadcast traffic
Network Address Translation (NAT)
Provides an IP proxy between a private LAN and a public network such as the Internet.
CSMA/CD
Solution which allows for verifying the absence of other traffic on a shared medium before transmitting in order to prevent collisions and loss of data in 802.3 networks
NAT
Solution which hides the internal IP addresses by modifying IP address information in IP packet headers while in transit across a traffic routing device
Broadcast
Transmission type which would be used to reach a networked host with unknown address
CSMA/CA
allows for controlling the shared medium in order to minimize collisions in 802.11 networks
All routers have finished updating their routing tables
known as a convergence state in routing
Maximum hop count Time to live (TTL)
mechanisms which can be used to prevent routing loops
A loopback interface on a router
provides the means for basic testing whether the router is on and operational
NAT
solutions alleviates the problem of the depleting IPv4 address space by allowing multiple hosts on the same private LAN to share a single public IP address
Dynamic routing
the process of the automated update of a routing table
