Windows 2000 or later or a UNIX server running Berkeley Internet Name
Domain (BIND) 4.9.7 or later.

87

you must upgrade all domain controllers to Windows Server 2012 and upgrade the
functional levels accordingly.

A

True—A domain running at the Windows Server 2012 R2 domain functional
level located in a forest running at a lower functional level supports domain-based
Windows Server 2012 R2 Active Directory features but not forest-based ones.

88
Q

A

True—You might do this if you are configuring your server for a directoryrelated application such as Exchange Server.

92
Q

    Directory database and SYSVOL folder, plus at least 100 MB for the transaction log
    files.
A

False—Additional storage of 500 MB for the Active Directory database is
required.

93
Q

Which of these is not a reason to set up an organization with separate domains for
discrete divisions of the company?
a. It can be administered either centrally or locally. The concept of delegation of
control in AD DS facilitates the assignment of individuals as local administrators.
b. This approach can facilitate decentralized administration of network resources.
c. For multiple Internet domain names, the domain can be built to mirror the
Internet functionality.
d. Multiple domains representing different geographical locations might reduce
the amount of replication traffic across low wide area network (WAN) links.

A

A. The idea of delegation is the reason to use organizational units, not to
separate divisions into domains.

94
Q

The main difference between trees and forests is ______________________.

A

Domains within a tree share a contiguous namespace, whereas domains located
in different trees in the same forest have a disjointed namespace.
For example, que.com and examcram.com are root domains in two
separate trees of the same forest.

95
Q

What is the main reason not to employ a single tree in all multiple domain enterprises?

A

Two companies merge and want to maintain their separate identities.

Their identities and indeed their Internet namespaces are best served
by having more than one tree in the forest.

96
Q

To install Active Directory on a Windows Server 2008 R2, there must be additional
disk space of _________________________.

A

500 MB for the Active Directory database and SYSVOL folder, plus at least

The larger the proposed network, the more disk space is necessary.
And in practical terms, you should have several gigabytes of available space at a
minimum.

domain.

A

True— Authority for these subdomains can be delegated to organizations so that
they can manage their own namespace.

122
Q

Even though the FQDN contains both the hostname and domain name, two hosts
from different domains cannot share the same hostname.

A

False—Because the FQDN contains both the hostname and domain name, two
hosts can share the same hostname, for example, search.Microsoft.com and
search.zdnet.com.

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.

for leasing to clients.

A

True–You can create a scope for each physical subnet on your network and use
this scope to define networking parameters.

before DHCP configures the client with a working set of TCP/IP parameters.

A

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.

A

Stateless address configuration and stateful address configuration

With both types of addresses, Router Advertisement messages include
address prefixes and stateful address configuration protocols.

with static IP addresses.

166
Q

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.

A

. 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
Q

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.

A

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
Q

If a DHCP client accepts an IP address, it can use the address for a predefined period
called a ________.

A

lease. If a client cannot obtain a lease of an IP address from a DHCP
server, it cannot initialize TCP/IP normally.

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.

address.

170
Q

management tasks from the command line, including creation of scopes.

A

netsh. You can use PowerShell or netsh; although Microsoft now favors the

and is useful for configuring servers that must always be reached at the same IP
address with a specified set of options.

173
