QUESTION NO:6
Your network consists of a single Active Directory site that includes two network segments. The
network segments connect by using a router that is RFC 1542 compliant.
You plan to use Windows Deployment Services (WDS) to deploy Windows Server 2008 R2
servers. All new servers support PreBoot Execution Environment (PXE).
You need to design a deployment strategy to meet the following requirements:
-Support Windows Server?2008 R2
-Deploy the servers by using WDS in both network segments
-Minimize the number of servers used to support WDS
What should you include in your design?
A. Deploy one server. Install WDS and DHCP on the server. Configure the IP Helper tables on the
router between the network segments.
B. Deploy two servers. Install WDS and DHCP on both servers. Place one server on each of the
network segments. Configure both servers to support DHCP option 60.
C. Deploy two servers. Install WDS and DHCP on both servers. Place one server on each of the
network segments. Configure both servers to support DHCP option 252.
D. Deploy two servers. Install WDS and DHCP on one server. Install DHCP on the other server.
Place one server on each of the network segments. Configure both servers to support DHCP
option 60.
Answer: A
Explanation:
http://support.microsoft.com/kb/926172
IP Helper table updates
The PXE network boot method uses DHCP packets for communication. The DHCP packets serve
a dual purpose. They are intended to help the client in obtaining an IP address lease from a DHCP
server and to locate a valid network boot server. If the booting client, the DHCP server, and the
network boot server are all located on the same network segment, usually no additional
configuration is necessary. The DHCP broadcasts from the client reach both the DHCP server and
the network boot server.
However, if either the DHCP server or the network boot server are on a different network segment
than the client, or if they are on the same network segment but the network is controlled by a
switch or a router, you may have to update the routing tables for the networking equipment in
order to make sure that DHCP traffic is directed correctly.
Such a process is known as performing IP Helper table updates. When you perform this process,
you must configure the networking equipment so that all DHCP broadcasts from the client
computer are directed to both a valid DHCP server and to a valid network boot server.
Note: It is inefficient to rebroadcast the DHCP packets onto other network segments. It is best to
only forward the DHCP packets to the recipients that are listed in the IP Helper table.
After the client computer has obtained an IP address, it contacts the network boot server directly in
order to obtain the name and the path of the network boot file to download. Again, this process is
handled by using DHCP packets.
Note: We recommend that you update the IP Helper tables in order to resolve scenarios in which
the client computers and the network boot server are not located on the same network segment.
QUESTION NO:20
Your network consists of a single Active Directory domain. The network includes a branch office
named Branch1. Branch1 contains 50 member servers that run Windows Server 2008 R2. An
organizational unit (OU) named Branch1Servers contains the computer objects for the servers in
Branch1. A global group named Branch1admins contains the user accounts for the administrators.
Administrators maintain all member servers in Branch1. You need to recommend a solution that
allows the members of Branch1admins group to perform the following tasks on the Branch1
member servers.
-Stop and start services
-Change registry settings
What should you recommend?
A. Add the Branch1admins group to the Power Users local group on each server in Branch1.
B. Add the Branch1admins group to the Administrators local group on each server in Branch1.
C. Assign the Branch1admins group change permissions to the Branch1Servers OU and to all
child objects.
D. Assign the Branch1admins group Full Control permissions on the Branch1Servers OU and to
all child objects.
Answer: B
Explanation:
Local admins have these rights.
Power Users do not
By default, members of the power users group have no more user rights or permissions than a
standard user account. The Power Users group in previous versions of Windows was designed to
give users specific administrator rights and permissions to perform common system tasks. In this
version of Windows, standard user accounts inherently have the ability to perform most common
configuration tasks, such as changing time zones. For legacy applications that require the same
Power User rights and permissions that were present in previous versions of Windows,
administrators can apply a security template that enables the Power Users group to assume the
same rights and permissions that were present in previous versions of Windows.
QUESTION NO:11
Your network contains an Active Directory forest named contoso.com.
You plan to deploy a new child domain named branch.contoso.com. The child domain will contain
two domain controllers. Both domain controllers will have the DNS Server server role installed. All
users and computers in the branch office will be members of the branch.contoso.com domain.
You need to plan the DNS infrastructure for the child domain to meet the following requirements:
-Ensure resources in the root domain are accessible by fully qualified domain names.
-Ensure resources in the child domain are accessible by fully qualified domain names.
-Provide name resolution services in the event that a single server fails for a prolonged period of
time.
-Automatically recognize when new DNS servers are added to or removed from the contoso.com
domain.
What should you include in your plan?
A. On both domain controllers, add a conditional forwarder for contoso.com and create a standard
primary zone for branch.contoso.com.
B. On both domain controllers, modify the root hints to include the domain controllers for
contoso.com. On one domain controller, create an Active Directory-integrated zone for
branch.contoso.com.
C. On one domain controller create an Active Directory-integrated zone for branch.contoso.com
and create an Active Directory-integrated stub zone for contoso.com.
D. On one domain controller, create a standard primary zone for contoso.com. On the other
domain controller, create a standard secondary zone for contoso.com.

Understanding DNS Zone Replication in Active Directory Domain Services
Applies To: Windows Server 2008, Windows Server 2008 R2
You can store Domain Name System (DNS) zones in the domain or application directory partitions
of Active Directory Domain Services (AD DS). A partition is a data structure in AD DS that
distinguishes data for different replication purposes. For more information, see Understanding
Active Directory Domain Services Integration.
The following table describes the available zone replication scopes for AD DS-integrated DNS
zone data.
When you decide which replication scope to choose, consider that the broader the replication
scope, the greater the network traffic caused by replication. For example, if you decide to have AD
DS-integrated DNS zone data replicated to all DNS servers in the forest, this will produce greater
network traffic than replicating the DNS zone data to all DNS servers in a single AD DS domain in
that forest.
AD DS-integrated DNS zone data that is stored in an application directory partition is not
replicated to the global catalog for the forest The domain controller that contains the global catalog
can also host application directory partitions, but it will not replicate this data to its global catalog.
AD DS-integrated DNS zone data that is stored in a domain partition is replicated to all domain
controllers in its AD DS domain, and a portion of this data is stored in the global catalog. This
setting is used to support Windows 2000.
If an application directory partition\’s replication scope replicates across AD DS sites, replication
will occur with the same intersite replication schedule as is used for domain partition data.
By default, the Net Logon service registers domain controller locator (Locator) DNS resource
records for the application directory partitions that are hosted on a domain controller in the same
manner as it registers domain controller locator (Locator) DNS resource records for the domain
partition that is hosted on a domain controller.
Primary zone
When a zone that this DNS server hosts is a primary zone, the DNS server is the primary source
for information about this zone, and it stores the master copy of zone data in a local file or in AD
DS. When the zone is stored in a file, by default the primary zone file is named rone_name.dns
and it is located in the %windir%\System32\Dns folder on the server.
Secondary zone
When a zone that this DNS server hosts is a secondary zone, this DNS server is a secondary
source for information about this zone. The zone at this server must be obtained from another
remote DNS server computer that also hosts the zone. This DNS server must have network
access to the remote DNS server that supplies this server with updated information about the
zone. Because a secondary zone is merely a copy of a primary zone that is hosted on another
server, it cannot be stored in AD DS.
Stub zone
When a zone that this DNS server hosts is a stub zone, this DNS server is a source only for
information about the authoritative name servers for this zone. The zone at this server must be
obtained from another DNS server that hosts the zone. This DNS server must have network
access to the remote DNS server to copy the authoritative name server information about the
zone.
You can use stub zones to:
. Keep delegated zone information current. By updating a stub zone for one of its child zones
regularly, the DNS server that hosts both the parent zone and the stub zone will maintain a current
list of authoritative DNS servers for the child zone.
. Improve name resolution. Stub zones enable a DNS server to perform recursion using the stub
zone\’s list of name servers, without having to query the Internet or an internal root server for the
DNS namespace.
. Simplify DNS administration. By using stub zones throughout your DNS infrastructure, you can
distribute a list of the authoritative DNS servers for a zone without using secondary zones.
However, stub zones do not serve the same purpose as secondary zones, and they are not an
alternative for enhancing redundancy and load sharing.
There are two lists of DNS servers involved in the loading and maintenance of a stub zone:
. The list of master servers from which the DNS server loads and updates a stub zone. A master
server may be a primary or secondary DNS server for the zone. In both cases, it will have a
complete list of the DNS servers for the zone.
. The list of the authoritative DNS servers for a zone. This list is contained in the stub zone using
name server (NS) resource records.
When a DNS server loads a stub zone, such as widgets.tailspintoys.com, it quenes the master
servers, which can be in different locations, for the necessary resource records of the authoritative
servers for the zone widgets.tailspintoys.com. The list of master servers may contain a single
server or multiple servers, and it can be changed anytime.

Group Policy Planning and Deployment Guide
You can use Windows Server 2008 Group Policy to manage configurations for groups of
computers and users, including options for registry-based policy settings, security settings,
software deployment, scripts, folder redirection, and preferences. Group Policy preferences, new
in Windows Server 2008, are more than 20 Group Policy extensions that expand the range of
configurable policy settings within a Group Policy object (GPO). In contrast to Group Policy
settings, preferences are not enforced. Users can change preferences after initial deployment. For
information about Group Policy Preferences, see Group Policy Preferences Overview.
Using Group Policy, you can significantly reduce an organization
QUESTION NO:4
Your company purchases 15 new 64bit servers as follows:
-Five of the servers have a single processor.
-Five of the servers have a single dual core processor.
-Five of the servers have two quad core processors.
You plan to deploy Windows Server 2008 R2 on the new servers by using Windows Deployment
Services (WDS). You need to recommend a WDS install image strategy that meets the following
requirements:
-Minimizes the number of install images
-Supports the deployment of Windows Server 2008 R2
What should you recommend?
A. one install image file that contains three install images
B. one install image file that contains a single install image
C. two install image files that each contain a single install image
D. three install image files that each contain a single install image
Answer: B
Explanation:
You only need one image per processor type
Windows Deployment Services Images
Windows Deployment Services uses two different types of images: install images and boot
images. Install images are the operating system images that will be deployed to Windows Server
2008 or Windows Vista client computers. A default installation image is located in the \Sources
directory of the Windows Vista and Windows Server 2008 installation DVDs. If you are using WDS
to deploy Windows Server 2008 to computers with different processor architectures, you will need
to add separate installation images for each architecture to the WDS server. Architecture-specific
images can be found on the architecture-specific installation media. For example, the Itanium
image is located on the Itanium installation media and the x64 default installation image is located
on the x64 installation media. Although you can create custom images, you only need to have one
image per processor architecture. For example, deploying Windows Server 2008 Enterprise
Edition x64 to a computer with 1 x64 processor and to a computer with 8 x64 processors in SMP
configuration only requires access to the default x64 installation image. Practice exercise 2 at the
end of this lesson covers the specifics ol adding a default installation image to a WDS server.

Explanation:
Certification authority hierarchies
The Microsoft public key infrastructure (PKI) supports a hierarchical certification authority (CA)
model. A certification hierarchy provides scalability, ease of administration, and consistency with a
growing number of commercial and other CA products.
In its simplest form, a certification hierarchy consists of a single CA. However, in general, a
hierarchy will contain multiple CAs with clearly defined parent-child relationships. In this model, the
child subordinate certification authorities are certified by their parent CA-issued certificates, which
bind a certification authority\’s public key to its identity. The CA at the top of a hierarchy is referred
to as the root authority, or root CA. The child CAs of the root CAs are called subordinate
certification authorities (CAs).
A root certification authority (CA) is the top of a public key infrastructure (PKI) and generates a
self-signed certificate. This means that the root CA is validating itself (self-validating). This root CA
could then have subordinate CAs that effectively trust it. The subordinate CAs receive a certificate
signed by the root CA, so the subordinate CAs can issue certificates that are validated by the root
CA. This establishes a CA hierarchy and trust path.

certification authorities (CAs).
Authentication and Authorization
Stand-alone CAs use local authentication for certificate requests, mainly through the Web
enrollment interface.
Stand-alone CAs provide an ideal service provider or commercial PKI provider platform for issuing
certificates to users outside of an Active Directory environment where the user identity is
separately verified and examined before the request is submitted to the CA.
Offline and Online CAs
Traditionally, the decision of whether to use either an online or offline CAs involves a compromise
between availability and usability versus security. The more sensitive that the key material is and
the higher the security requirements are, the less accessible the CA should be to users.
Specifying CA Roles
An ideal PKI hierarchy design divides the responsibility of the CAs. A topology that is designed
with requirements that have been carefully considered provides the most flexible and scalable
enterprise configuration. In general, CAs are organized in hierarchies. Single tier hierarchies might
not provide adequate security compartmentalization, extensibility and flexibility. Hierarchies with
more than three tiers might not provide additional value regarding security, extensibility and
flexibility.
The most important consideration is protecting the highest instance of trust as much as possible.
Single-tier hierarchies are based on the need to compartmentalize risk and reduce the attack
surface that is available to users who have malicious intent. A larger hierarchy is much more
difficult to administer, with little security benefit.
Depending on the organization\’s necessities, a PKI should consist of two or three logical levels
that link several CAs in a hierarchy. Administrators who understand the design requirements for a
three-level topology may also be able to build a two-level topology.
A three-tier CA hierarchy consists of the following components:
A root CA that is configured as a stand-alone CA without a network connection
One or more intermediate CAs that are configured as stand-alone CAs without a network
connection
One or more issuing CAs that are configured as enterprise CAs that are connected to the network

A. In the Active Directory domain, add the branch office administrators to the Server Operators
builtin local group.
B. In the Active Directory domain, add the branch office administrators to the Network
Configuration Operators builtin local group.
C. In each branch office, migrate the DHCP Server server role to the file server. On each file
server, add the branch office administrator to the DHCP Administrators local group.
D. In each branch office, migrate the DHCP Server server role to the file server. In the Active

DHCP Administrators
Members of the DHCP Administrators group can view and modify any data at the DHCP server.
DHCP Administrators can create and delete scopes, add reservations, change option values,
create superscopes, or perform any other activity needed to administer the DHCP server,
including export or import of the DHCP server configuration and database. DHCP Administrators
perform these tasks using the Netsh commands for DHCP or the DHCP console. For more
information, see DHCP tools.
Members of the DHCP Administrators group do not have unlimited administrative rights. For
example, if a DHCP server is also configured as a DNS server, a member of the DHCP
Administrators group can view and modify the DHCP configuration but cannot modify DNS server
configuration on the same computer.
Because members of the DHCP Administrators group have rights on the local computer only,
DHCP Administrators cannot authorize or unauthorize DHCP servers in Active Directory. Only
members of the Domain Admins group can perform this task. If you want to authorize or
unauthorize a DHCP server in a child domain, you must have enterprise administrator credentials
for the parent domain. For more information about authorizing DHCP servers in Active Directory,
see Authorizing DHCP servers and Authorize a DHCP server in Active Directory.
Using groups to administer DHCP servers in a domain
When you add a user or group to a DHCP Users or DHCP Administrators group on a DHCP
server, the rights of the DHCP group member do not apply to all of the DHCP servers in the
domain. The rights apply only to the DHCP service on the local computer.
QUESTION NO:3
Your network contains a Webbased Application that runs on Windows Server 2003. You plan to
migrate the Webbased Application to Windows Server 2008 R2. You need to recommend a server
configuration to support the Webbased Application.

Web Edition meets the requirements
Windows Web Server 2008 R2
Windows Web Server 2008 R2 is designed to function specifically as a Web application server.
Other roles, such as Windows Deployment Server and Active Directory Domain Services (AD DS),
are not supported on Windows Web Server 2008 R2. You deploy this server role either on a
screened subnet to support a website viewable to external hosts or as an intranet server. As
appropriate given its stripped-down role, Windows Web Server 2008 R2 does not support the
high-powered hardware configurations that other editions of Windows Server 2008 R2 do.
Windows Web Server 2008 R2 has the following properties:
Supports a maximum of 32 GB of RAM and 4 sockets in symmetric multiprocessing (SMP)
configuration
You should plan to deploy Windows Web Server 2008 R2 in the Server Core configuration, which
minimizes its attack surface, something that is very important on a server that interacts with hosts
external to your network environment. You should plan to deploy the full version of Windows Web

You need to plan a name resolution strategy for the Paris office that meets the following
requirements:
-If a WAN link fails, clients must be able to resolve hostnames for contoso.com.
-If a WAN link fails, clients must be able to resolve hostnames for newyork.contoso.com.
-The DNS servers in Paris must be updated when new authoritative DNS servers are added to
newyork.contoso.com.
What should you include in your plan?
A. Configure conditional forwarding for contoso.com. Configure conditional forwarding for
newyork.contoso.com.
B. Create a standard secondary zone for contoso.com. Create a standard secondary zone for
newyork.contoso.com.

Understanding Zone Delegation
Applies To: Windows Server 2008, Windows Server 2008 R2
Domain Name System (DNS) provides the option of dividing up the namespace into one or more
zones, which can then be stored, distributed, and replicated to other DNS servers. When you are
deciding whether to divide your DNS namespace to make additional zones, consider the following
reasons to use additional zones:
. You want to delegate management of part of your DNS namespace to another location or
department in your organization.
. You want to divide one large zone into smaller zones to distribute traffic loads among multiple
servers, improve DNS name resolution performance, or create a more-fault-tolerant DNS
environment.
. You want to extend the namespace by adding numerous subdomains at once, for example, to
accommodate the opening of a new branch or site.
Secondary zone
When a zone that this DNS server hosts is a secondary zone, this DNS server is a secondary
source for information about this zone. The zone at this server must be obtained from another
remote DNS server computer that also hosts the zone. This DNS server must have network
access to the remote DNS server that supplies this server with updated information about the
zone. Because a secondary zone is merely a copy of a primary zone that is hosted on another
server, it cannot be stored in AD DS.
