System (EFS), smurt curd logon, Secure Socket Luyer/Trunsport Luyer Securlty
(SSL/TLS), und dlgltul slgnutures.

2. Whut ls Active Directory Domain Services Role?

Active Directory Domain Services (AD DS) stores information about users, computers,
and other devices on the network. AD DS helps administrators securely manage this
information and facilitates resource sharing and collaboration between users. AD DS is
also required to be installed on the network in order to install directory-enabled
applications such as Microsoft Exchange Server and for applying other Windows Server
technologies such as Group Policy.

3. Whut ls Active Directory Federation Services Role?

Active Directory Federation Services (AD FS) provides Web single-sign-on (SSO) technologies to
authenticate a user to multiple Web applications using a single user account. AD FS
accomplishes this by securely federating, or sharing, user identities and access rights, in the
form of digital claims, between partner organizations.

. Whut ls Active Directory Lightweight Directory Services Role?

Organizations that have applications which require a directory for storing application data can
use Active Directory Lightweight Directory Services (AD LDS) as the data store. AD LDS runs as a
non-operating-system service, and, as such, it does not require deployment on a domain
controller. Running as a non-operating-system service allows multiple instances of AD LDS to run
concurrently on a single server, and each instance can be configured independently for servicing
multiple applications.

5. Whut ls Active Directory Rights Management Services (AD RMS) Role?

AD RMS is information protection technology that works with AD RMS-enabled applications to
help safeguard digital information from unauthorized use. Content owners can define exactly
how a recipient can use the information, such as who can open, modify, print, forward, or take
other actions with the information. Organizations can create custom usage rights templates
such as "ConfidentialͶRead Only" that can be applied directly to information such as financial
reports, product specifications, customer data, and e-mail messages.

6. Whut ls un Application Server Role?

Application Server provides a complete solution for hosting and managing high-performance
distributed business applications. Integrated services, such as the .NET Framework, Web Server
Support, Message Queuing, COM+, Windows Communication Foundation, and Failover
Clustering support boost productivity throughout the application life cycle, from design and
development through deployment and operations.

7. Whut ls Dynamic Host Configuration Protocol (DHCP) Server Role?

The Dynamic Host Configuration Protocol allows servers to assign, or lease, IP addresses to
computers and other devices that are enabled as DHCP clients. Deploying DHCP servers on the
network automatically provides computers and other TCP/IP-based network devices with valid
IP addresses and the additional configuration parameters these devices need, called DHCP
options, that allow them to connect to other network resources, such as DNS servers, WINS
servers, and routers. DORA, DISCOVER - OFFER - REQUEST - ACKNOWLEDGEMENT. It uses Port
Numbers 67 for Client and 68 for Server.

8. Whut ls DNS Server Role?

Domain Name System (DNS) provides a standard method for associating names with numeric
Internet addresses. This makes it possible for users to refer to network computers by using
easy-to-remember names instead of a long series of numbers. DNS is also known as a
distributed database that provides mapping between IP addresses and Host names. DNS uses
port No. 53 for DNS Zone transfers

9. Whut ls Hyper-VΡ?

Hyper-V provides the services that you can use to create and manage virtual machines and their
resources. Each virtual machine is a virtualized computer system that operates in an isolated
execution environment. This allows you to run multiple operating systems simultaneously.

10. Whut ls Network Policy and Access Services Role?

Network Policy and Access Services delivers a variety of methods to provide users with local and
remote network connectivity, to connect network segments, and to allow network
administrators to centrally manage network access and client health policies. With Network
Access Services, you can deploy VPN servers, dial-up servers, routers, and 802.11 protected
wireless access. You can also deploy RADIUS servers and proxies, and use Connection Manager
Administration Kit to create remote access profiles that allow client computers to connect to
your network.

11. Whut ls Universal Description, Discovery, and Integration Services (UDDI) Role?

Universal Description, Discovery, and Integration (UDDI) Services provides UDDI capabilities for
sharing information about Web services within an organization's intranet, between business
partners on an extranet, or on the Internet. With UDDI Services you can prevent duplication of
effort by promoting reuse of existing development work.

12. Whut ls Web Server (IIS) Role?

Web Server (IIS) enables sharing of information on the Internet, an intranet, or an extranet. It is
a unified Web platform that integrates IIS 7.0, ASP.NET, and Windows Communication.
Foundation. IIS 7.0 also features enhanced security, simplified diagnostics, and delegated

13. Whut ls Windows Deployment Services Role?

You can use Windows Deployment Services to install and configure Windows operating
systems remotely on computers with Pre-boot Execution Environment (PXE) boot ROMs.
Administration overhead is decreased through the implementation of the Wds Mgmt Microsoft
Management Console (MMC) snap-in, which manages all aspects of Windows Deployment
Services. Windows Deployment Services also provides end users an experience consistent with
Windows Setup.

Feutures, generully speuklng, do not descrlbe the prlmury functlon of u server. Feutures

1. What are Microsoft .NET Framework 3.0 Features?

Microsoft .NET Framework 3.0 combines the power of the .NET Framework 2.0 APIs with new
technologies for building applications that offer appealing user interfaces, protect your
customersÍ› personal identity information, enable seamless and secure communication, and
provide the ability to model a range of business processes.

2. Whut ls BitLocker Drive Encryption Feature?

BitLocker Drive Encryption helps to protect data on lost, stolen, or inappropriately
decommissioned computers by encrypting the entire volume and checking the integrity of early
boot components. Data is decrypted only if those components are successfully verified and the
encrypted drive is located in the original computer. Integrity checking requires a compatible
trusted platform module (TPM).
What does a Server Core installation do?
A Server Core installation is a minimal installation for running the Active Directory Domain Services,
AD LDS, DHCP Server, DNS Server, File Services, Print Server, and Streaming Media Services server roles.
A server running a Server Core installation does not have a Graphical user interface or provide the ability
to run applications. you might need to become familiar with command-line tools.
