Q

Service that allows DHCP requests to be processed on a multisegment network.

The DHCP relay agent or proxy is used to forward requests through a router to a DHCP server.

(Without a relay agent, non-BootP routers prevent all broadcasts, including DHCP broadcasts, from passing through.)

The ability of a DNS server to send a request to another DNS server.

There are several types of forwarding, including external forwarding (forwarding to a server outside your organization) and conditional forwarding (forwarding based on rules set up by an administrator).

Q

In Microsoft networks, an arrangement of client and server computers referenced by a specific name that shares a single security permissions database.

On the Internet, a domain is a named collection of hosts and subdomains, registered with a unique name by the InterNIC.

A

Domain

18
Q

A Windows Server 2012 computer that includes a copy of the Active Directory data store.

Domain controllers contain the security information required to perform services related to the Active Directory.

A

Domain controller

19
Q

A standard that allows clients or DHCP to register with DNS automatically.

This means that DNS can build its zone database on-the-fly.

A

Dynamic DNS (DDNS)

20
Q

A range of IP addresses that DHCP does not automatically assign to clients.

A

Exclusion

21
Q

A record that is used to associate a host’s name statically to its IP addresses.

Also called an A record for TCP/IP v4 and an AAAA record for TCP/IP v6.

A

Host record

22
Q

IPv4 and IPv6 packet type defining a single address that can be received by multiple devices at the same time but not by everyone.

Multicast allows a server to send a stream of data to multiple clients.

Client computers subscribe to a group and communicate by sending packets to the multicast address.

In unicast communication, by contrast, the server needs to send the same packets to each computer individually.

IPv6 uses multicast functionality to let a device query multiple network devices for their MAC addresses.

This facilitates network communication (IPv4 broadcast ARP functionality).

A

Multicast

23
Q

A server that can give an authoritative answer to name resolution queries about that domain.

A

Name server

24
Q

This record lists the name servers for a domain and allows other name servers to look up names in your domain.

A

Name server (NS) record

25
Q

A value that uniquely identifies a network.

Every machine on the network shares that network address as part of its IP address.

In IPv4, the classful address (as in class A, class B, or class C).

In classless addressing, this is the number of network bits defined by the subnet mask.

In IPv6, this is the hexadecimal value specified by the number of bits in the prefix (or by the slash notation value).

In the IPv4 address 130.57.30.56, for example, 130.57 is the network address.

A

Network address

26
Q

A DNS database that needs to be built manually.

Clients cannot automatically update the DNS server.

A

Non-Dynamic DNS (NDDNS)

27
Q

Command-line utility for testing a DNS server.

A

Nslookup

28
Q

A utility that allows an individual to watch or retrieve packets from a network cable.

A

Packet sniffer

29
Q

Used to associate an IP address to its host’s name.

This record is necessary because IP addresses begin with the least-specific portion (the network) and end with the most-specific portion (the host), whereas hostnames begin with the most- specific portion and end with the least specific.

A

Pointer (PTR) record

30
Q

This zone is responsible for maintaining all of the records for the DNS zone.

It contains the primary copy of the DNS database and all record updates occur here.

You create a new primary zone whenever you create a new DNS domain.

A

Primary zone

31
Q

Sending email to a server so that it will forward it to another server for delivery.

A

Relay

32
Q

IP-to-MAC mapping that allows a DHCP server always to give the same IP address to a DHCP client.

Reserved IP numbers are part of a DHCP pool that are set aside for machines with specific ID numbers or MAC addresses.

A

Reservation

33
Q

Any machine issuing queries to a DNS server is a resolver, although technically a resolver is a software process that finds answers to queries for DNS data.

Clients issue DNS requests through processes called resolvers.

A

Resolver

34
Q

A building block of a clustered application.

A

Resource

35
Q

An entry in a DNS database that specifies the availability of specific DNS services.

For example, an MX record specifies the IP address of a mail server, and (A) host records specify the IP addresses of workstations on the network.

A

Resource record (RR)

36
Q

The DNS process of cleaning up old resource records in the DNS database.

Scavenging uses the resource record time stamp to determine if the record is stale.

A

Scavenging

37
Q

Contiguous range of addresses for DHCP.

There’s usually one scope per physical subnet.

A scope can cover a Class A, Class B, or Class C network address or an IPv6 address.

A

Scope

38
Q

Noneditable copy of the DNS database that is used for load balancing (also referred to as load sharing).

A secondary zone gets its database from the primary zone and provides for fault tolerance and increased network performance, especially in organizations with WAN connections.

A

Secondary DNS zone

39
Q

Ties the location of a service (like a domain controller) with information about how to contact the service.

A

Service (SRV) record

40
Q

A lower-level domain-normally a child domain off of a parent domain.

A

Subdomain

41
Q

Enables the DHCP server to provide addresses from more than one scope to clients on the same physical subnet.

A

Superscope

42
Q

A service that resolves a NetBIOS name to a TCP/IP address.

WINS is used primarily in older operating systems (Windows 95, 98, and NT).

A

Windows Internet Name Service (WINS)
