100
A type of DNS data record that maps the IP address of an Internet-connected device to its domain name.
What is address resource record
100
A hierarchical way of tracking domain names and their addresses, devised in the mid-1980s. The ___ database does not rely on one file or even one server, but rather is distributed over several key computers across the Internet to prevent catastrophic failure if one or a few computers go down. ___ is a TCP/IP service that belongs to the Application layer of the OSI model.
What is DNS (Domain Name System or Domain Name Service)
100
The shorthand convention used to represent IPv4 addresses and make them more easily readable by humans. In _____ ______ _______, a decimal number between 0 and 255 represents each binary octet. A period, or dot, separates each decimal.
What is dotted decimal notation
100
A service available on computers running the Windows 98, Me, 2000, XP, Vista, Server 2003, or Server 2008 operating system that automatically assigns the computer’s network interface an IP address from the range of 169.254.0.0 to 169.254.255.255 if an IP address hasn’t been assigned to that interface.
What is APIPA (Automatic Private IP Addressing
100
An Application layer protocol in the TCP/IP suite that uses a central list of IP addresses and their associated devices’ MAC addresses to assign IP addresses to clients dynamically. ________ was the precursor to DHCP.
What is BOOTP (Bootstrap Protocol)
200
The request for a response generated when one device pings another device.
What is Echo request
200
A record in an ARP table that is created when a client makes an ARP request that cannot be satisfied by data already in the ARP table.
What is Dynamic ARP table entry
200
The response signal sent by a device after another device pings it.
What is echo reply
200
An Application layer protocol in the TCP/IP suite that manages the dynamic distribution of IP addresses on a network. Using ______ to assign IP addresses can nearly eliminate duplicate-addressing problems.
What is DHCP (Dynamic Host Configuration Protocol)
200
A core protocol in the TCP/IP suite that belongs in the Network layer of the OSI model. ____ obtains the MAC (physical) address of a host, or node, and then creates a local database that maps the MAC address to the host’s IP (logical) address.
What is ARP (Address Resolution Protocol)
300
The symbolic name that identifies a domain. Usually, a _____ _______ is associated with a company or other type of organization, such as a university or military unit.
What is domain name
300
A type of address specified in IPv6 that represents a group of interfaces, any one of which (and usually the first available of which) can accept a transmission. At this time, _______ addresses are not designed to be assigned to hosts, such as servers or workstations, but rather to routers.
What is Anycast address
300
A text file that associates TCP/IP host names with IP addresses.
What is host file
300
An IP address that is assigned to a device upon request and may change when the lease expires or is terminated.
What is Dynamic IP address
300
A workstation that doesn’t contain a hard disk, but instead relies on a small amount of read-only memory to connect to a network and to pick up its system files.
What is diskless workstation
400
A ____ ____ ____ that corresponds to a country. For example, the ____ ____ ____ for Canada is .ca, and the country code TLD for Japan is .jp.
What is Country code TLD Or Top Level Domain
400
A term used to describe each trip a unit of data takes from one connectivity device to another. Typically, ____ is used in the context of router-to-router communications.
What is hop
400
A method of dynamically updating DNS records for a host. ______ client computers are configured to notify a service provider when their IP addresses change, then the service provider propagates the DNS record change across the Internet automatically.
What is DDNS (Dynamic DNS)
400
A nickname for a node’s host name. Aliases can be specified in a local host file.
What is alias
400
An Application layer protocol used to send and receive files via TCP/IP.
What is FTP (File Transfer Protocol
500
TCP/IP ports in the range of 49,152 through 65,535, which are open for use without requiring administrative privileges on a host or approval from IANA.
What is Dynamic Ports
500
A database of records that maps MAC addresses to IP addresses. The ___ _____ is stored on a computer’s hard disk where it is used by the ARP utility to supply the MAC addresses of network nodes, given their IP addresses.
What is ARP table
500
A host name plus domain name. For example, a host belonging to the loc.gov domain might be called Jasmine, making its _____ ______ ____ _____ Jasmine.loc.gov
What is fully qualified host name
500
A group of computers that belong to the same organization and have part of their IP addresses in common.
What is Domain
500
A variable-length field at the beginning of an IPv6 address that indicates what type of address it is (for example, unicast, anycast, or multicast).
What is Format Prefix
