Win2K Network Managing Ch7

Front 1

The zone data is stored in the Active Directory database rather than in a zone file.

Back 1

Active Directory integrated zone

Front 2

Works at the Internet layer and is responsible for mapping IP addresses to MAC addresses assigned to the network interface adapter. These can be either dynamic or static entries. Dynamic entries are stored in the ARP cache for two or 10 minutes. Static entries stay in the cache until the computer is restarted.

Back 2

Address Resolution Protocol (ARP)

Front 3

This is the 32-bit number of the router on the local network, which is used to communicate with hosts outside of the local subnet.

Back 3

default gateway

Front 4

Used for two essential tasks: host name to IP address resolution and for the location of network services, such as domain controllers that provide user authentication.

Back 4

Domain Name System (DNS)

Front 5

Used to centralize the administration of IP addresses and various options, and eliminate the administrative overhead of statically assigning the information to each network host.

Back 5

Dynamic Host Configuration Protocol (DHCP)

Front 6

Used to perform the standard host name to IP address forward lookup queries.

Back 6

forward lookup zone

Front 7

Describes the location of the host in relation to the DNS namespace. For example a computer named "webserver" in the marketing domain of Bayside.com would have the FQDN of webserver.marketing.bayside.com.

Back 7

fully qualified domain name (FQDN)

Front 8

Any computer that is a member of a specific DNS domain within the network structure.

Back 8

host

Front 9

Operates at the network layer and is used to exchange status and error information between two hosts.

Back 9

Internet Control Message Protocol (ICMP)

Front 10

Operates at the network layer and is used to manage network and host information when multicasting is used.

Back 10

Internet Group Management Protocol (IGMP)

Front 11

The Internet layer protocol responsible for the addressing and routing of packets so that they are delivered to the correct host on the local network or across routers to a host on another subnet.

Back 11

Internet Protocol (IP)

Front 12

The 32-bit number that uniquely identifies a host on a TCP/IP network.

Back 12

IP address

Front 13

A command used to verify the addressing parameters assigned to a computer.

Back 13

ipconfig

Front 14

The ipconfig command plus the all parameter is used to produce a full display of assigned parameters.

Back 14

ipconfig/all

Front 15

If the DNS server cannot resolve a name, it gives the requestor a pointer to another DNS server that is authoritative for the next level of the FQDN supplied.

Back 15

iterative query

Front 16

The sending of a message to multiple clients, or a group of clients.

Back 16

multicasting

Front 17

A command that combines the functions of the ping and tracert commands. The ________ command checks network connectivity by sending echo request messages to each router between a source and destination host and then computing the result based on packets returned from each router.

Back 17

pathping

Front 18

A command used to test for connectivity between hosts on the network by sending ICMP packets to a remote computer and listening for an echo reply from the remote host.

Back 18

ping

Front 19

A command that specifies the return of a complete and full answer to the query, not a pointer to another DNS server.

Back 19

recursive query

Front 20

A specific type of zone that performs reverse IP address to host name resolution queries.

Back 20

reverse lookup zone

Front 21

A range of IP addresses configured on a DHCP server that can be handed out to network clients.

Back 21

scope

Front 22

The DNS zone file is stored as a regular read/write text file in the %systemroot%\system32\dns folder.

Back 22

standard primary zone

Front 23

A read-only zone file is copied from a configured standard primary zone.

Back 23

standard secondary zone

Front 24

The 32-bit number that identifies the network to which a TCP/IP host belongs

Back 24

subnet mask

Front 25

A grouping of scopes created for multiple subnets on a physical network.

Back 25

superscope

Front 26

A command used to determine the route taken to a destination by sending ICMP echo packets with varying time-to-live (TTL) values to the destination.

Back 26

tracert

Front 27

Operates at the transport layer and is responsible for the reliable transmission of data on a TCP/IP network.

Back 27

Transmission Control Protocol (TCP)

Front 28

Consists of a suite of protocols and utilities that are used for network communication and troubleshooting on local networks and the Internet.

Back 28

Transmission Control Protocol/Internet Protocol (TCP/IP)

Front 29

A connectionless protocol that functions at the transport layer and provides no guarantee of delivery.

Back 29

User Datagram Protocol (UDP)

Front 30

A Windows 2000 service that is used to resolve NetBIOS names to IP addresses.

Back 30

Windows Internet Name Service (WINS)

Front 31

A command used on Windows 9x machines to display the TCP/IP configuration settings.

Back 31

winipcfg

Front 32

A DNS configuration file that holds all of the resource records for the domain, such as computer name records, mail exchanger records, and service records.

Back 32

zone file

Front 33

The copying of the DNS database information between the primary and secondary zones.

Back 33

zone transfer
