In an _______ DNS query, the queried name server provides the best answer it
currently has to the resolver
iterative. A DNS server typically performs this type of query to other DNS
servers after it has received a recursive query from a resolver.
136
Each DNS name server stores information about a discrete portion of the Internet
namespace. Such a portion is known as a(n)________.
zone. The DNS server that is primarily responsible for each zone is
considered to be authoritative for that zone.
137
When you first install DNS on a server connected to the Internet, it should download
the latest set of root ________ automatically
hints. This is a text file that contains resource records for every available
root server.
138
A host resource record maps the FQDN of any computer (host) in the domain to its IP
address. Normally, the appropriate host record is dynamically added or updated when
the host obtains its IP configuration from DHCP. An A resource record is used on an
IPv4 network, and an ________ resource record is used on an IPv6 network.
AAAA. If your network is configured to use both IPv4 and IPv6, each host
will have both A and AAAA resource records.
139
________ forwarding is the relaying of a DNS request for zone information for
specific domains from one server to another one.
Conditional. This occurs when the first server is unable to process the
request.
140
________-level domains include .com, .org, .edu, and .gov.
Top. Along with about two dozen top-level domain names, there are also
two-letter ISO standard country name abbreviations used as top-level domains.
141
If the DNS Server is hosting Active Directory ________ DNS Zones, you must install
the AD DS role service on the server
Integrated. The DNS Server role is typically selected during the installation
of Active Directory Domain Services (AD DS) or via PowerShell.
142
A ________ zone is a master copy of zone data hosted on a DNS server that is the

153
DHCP works by providing IP addressing information from a pool of addresses called
a scope.
True—The scope is defined in the DHCP server’s database.
154
A DHCP server leases an IP address to the DHCP client for only a specified term.
The default term is 4 days.
False—The default lease term is 8 days. To continue using its leased IP address, a
DHCP client will attempt to renew its lease before it expires.
155
Every DHCP server requires at least one scope with a pool of IP addresses available
for leasing to clients.
True--You can create a scope for each physical subnet on your network and use
this scope to define networking parameters.
156
You can create only one scope on a DHCP server.
False—You can create multiple scopes to act as a backup method for other DHCP
servers and for assigning IP addresses specific to a subnet, such as default
gateway addresses.
157
The DHCP option 003 Router specifies the IP address of the default gateway
True—The gateway is the interface to which the host sends packets, which are
destined for another subnet.
158
A DHCP relay agent is a means to forward BOOTP broadcasts to other subnets in
search of a DHCP server.
True--A DHCP relay agent is a Windows Server 2012 R2 computer configured
with the Remote Access role (also known as Routing and Remote Access) to pass
BOOTP broadcasts.
159
A filter is a routing technology that transmits data to all possible destinations on the
local subnet.
False-- This describes a broadcast, permits the sender to send the data only once,
and all receivers can copy it.
160
Stateless address configuration is a type of IPv6 address autoconfiguration that uses a
stateful address configuration protocol such as DHCPv6 to obtain nonlink-local
addresses and other IPv6 configuration parameters.
False—This describes stateful address configuration
161
Dynamic Hyper Configuration Protocol is a service that allows a server to assign IP
addresses to host computers on a subnet.
False—This describes Dynamic Host Configuration Protocol.
162
PreBoot Execution Environment refers to a bootable ROM chip.
True—This enables client computers without an operating system to boot and
connect to the network for locating a WDS server.
163
A DHCP server and a DHCP client both need to go through a ____-phase process
before DHCP configures the client with a working set of TCP/IP parameters.
4
Note that many of the communications are in the form of broadcasts. The
broadcast nature of these communications can present a major problem if routers on
an internetwork cannot forward these DHCP messages.
164
DHCPv6 uses which types of address configuration?
Stateless address configuration and stateful address configuration
With both types of addresses, Router Advertisement messages include
address prefixes and stateful address configuration protocols.
165
A(n) ________ is a range of IP addresses within a scope that you do not want to have
used by DHCP in leasing addresses to clients.
Exclusion
Typically, these are IP addresses of computers such as servers configured
with static IP addresses.
166
With the release of Windows Server 2008 R2, Microsoft included a DHCP Filter
function. Windows Server 2012 and Windows Server 2012 R2 continue this function,
which allows you to specify a MAC address or range and allow or deny IP address
assignment on the network.
. Filter
This can be useful if you have a collection of servers, perhaps a
development pool of virtual machines you don’t want to receive IP addresses from a
particular DHCP server.
167
In an Active Directory Domain Services (AD DS) domain, you must authorize the
DHCP server in Active Directory before it can lease IP addresses. This is to prevent
rogue DHCP servers from leasing improper IP addresses that would result in
communication problems.
rogue
When a domain controller or member server running DHCP starts up, it
queries AD DS for the list of authorized servers as identified by their IP addresses. If
its IP address is not present on this list, the DHCP Server service does not complete
its startup sequence.
168
If a DHCP client accepts an IP address, it can use the address for a predefined period
called a ________.
lease. If a client cannot obtain a lease of an IP address from a DHCP
server, it cannot initialize TCP/IP normally.
169
In Windows Server 2012 R2, DHCP is installed and configured as a server role.
Before installing DHCP, ensure that the server is configured with a ________IP
address that is compatible with the scope that you will be configuring for lease
purposes.
static. The DHCP server needs to have a static rather than a dynamic IP
address.
170
In addition to PowerShell, you can also use ________commands to perform DHCP
management tasks from the command line, including creation of scopes.
netsh. You can use PowerShell or netsh; although Microsoft now favors the
use of PowerShell cmdlets
171
In configuring DHCP scope properties, there is a setting that enables you to
automatically update the host (A) and pointer (PTR) records on the authoritative
________ servers.
DNS or Domain Name Service. DNS provides a name to the IP address
resolution.
172
You can configure DHCP so that a DHCP server always assigns the same IP address
to a client computer. This feature is known as a client ________.
reservation. A reservation maps the IP address to a specific MAC address
and is useful for configuring servers that must always be reached at the same IP
address with a specified set of options.
173
To authorize your DHCP server, you must be a member of the ________ Admins
group.
Enterprise. Authorization of a DHCP server in Active Directory helps
prevent rogue DHCP servers from leasing improper IP addresses.
174
The ________ protocol is a UDP network protocol used by a network client to obtain
its IP address automatically.
Bootstrap or BOOTP. This is usually done during the bootstrap process
when a computer is starting up.
175
```
Vendor class is a(n) ________class used to identify a client’s vendor type and
configuration when obtaining a DHCP lease.
```
```
options. You can use the vendor class ID option (code 60) to specify vendor
classes.
```
176

________.
RRAS or Routing and Remote Access Service. A DHCP relay agent is a
server configured to relay DHCP broadcast messages from one ________ to another
177
