Q
  1. What system is used to translate www.microsoft.com to an IP address?
    a) DNS
    b) WINS
    c) DHCP
    d) ARP
A

Answer: a) DNS

Difficulty: Easy
Section Reference: Exploring DNS
Explanation: Domain Name System (DNS) is a hierarchical client/server-based distributed database management system that translates domain/hosts names to IP addresses. Your organization most likely has one or more DNS servers that provide name resolution for your company.

    d) WINS
A

Answer: d) WINS

Difficulty: Easy

    c) DHCP
    d) WINS
A

Answer: c) DHCP

Difficulty: Easy
Section Reference: DHCP Services
Explanation: It would take hours to configure every host IP configuration, including IP address, addresses of DNS and WINS servers, and any other parameters. Thus, most organizations use Dynamic Host Configuration Protocol (DHCP) services to automatically assign IP addresses and related parameters (including subnet mask, default gateway, and length of the lease) so that a host can immediately communicate on an IP network when it starts.

Q
  1. What service replicates information of every object in a tree and forest so that you can quickly find those objects?
    a) LDAP server
    b) global catalog
    c) Infrastructure Master
    d) PDC Emulator
A

Answer: b) global catalog

Difficulty: Medium
Section Reference: Looking at Global Catalogs
Explanation: A global catalog replicates the information of every object in a tree and forest. However, rather than store the entire object, it stores just those attributes that are most frequently used in search operations, such as a user’s first and last name, computer name, and so forth. By default, a global catalog is created automatically on the first domain controller in the forest, but any domain controller can be made into a global catalog.

Answer: d) Use the Delegate of Authority wizard.

Difficulty: Medium
Section Reference: Introducing Organizational Units
Explanation: By delegating administration, you can assign a range of administrative tasks to the appropriate users and groups. For instance, you can assign basic administrative tasks to regular users or groups and leave domain-wide and forest-wide administration to members of the Domain Admins and Enterprise Admins groups.

Difficulty: Easy
Section Reference: Introducing Directory Services with Active Directory
Explanation: A Windows domain is a logical unit of computers and network resources that defines a security boundary. A domain uses a single Active Directory database to share its common security and user account information for all computers within the domain, allowing centralized administration of all users, groups, and resources on the network.

Section Reference: Introducing Directory Services with Active Directory
Explanation: A domain controller is a Windows server that stores a replica of the account and security information for the domain and defines the domain boundaries. To make a computer running Windows Server 2008 a domain controller, you must install the Active Directory Domain Services and execute the dcpromo (short for dc promotion) command.

A

Answer: forests

Difficulty: Easy
Section Reference: Introducing Directory Services with Active Directory
Explanation: A forest is made of one or more trees (although most people think of a forest as two or more trees). A forest varies from a tree because it uses disjointed namespaces between the trees.

A

Answer: A site

Difficulty: Easy
Section Reference: Introducing Sites and Domain Controllers
Explanation: A site is one or more IP subnets that are connected by a high-speed link, typically defined by a geographical location. Suppose that you have a four-story office building. Although the building includes several subnets, all computers within the building use layer-2 and layer-3 switches to communicate with each other.

Q

22. What do you need to do with your forests and domains so that you can use all available features?

A

Answer: upgrade to the highest domain and forest functional levels

Difficulty: Easy
Section Reference: Defining Functional Levels
Explanation: The functional level of a domain or forest depends on which Windows Server operating system versions are running on the domain controllers in that domain or forest. The functional level also controls which advanced features are available in the domain or forest. To get all the features available with Active Directory, you must have the latest version of the Windows Server operating system, and you have to use the highest forest and domain functional level.

Q

Short Answer

23. What technology is used to standardize the Windows environment on all client computers?

A

Answer: group policies

Difficulty: Easy
Section Reference: Introducing Group Policy
Explanation: One of Active Directory’s most powerful features is Group Policy, which controls the working environment for user accounts and computer accounts. Group Policy provides centralized management and configuration of operating systems, applications, and user settings in an Active Directory environment.

A

LDAP (Lightweight Directory Access Protocol)

28
Q
  1. The ______ are roles that provide certain functions that can only be handled by one domain controller.
A

FSMO - FLEXIBLE SINGLE MASTER OPERATIONS role

Active Directory uses multi-master replication, which means that there is no master domain controller, commonly referred to as a primary domain controller within Windows NT domains. However, because there are certain functions that can be handled by only one domain controller at a time, Active Directory uses Flexible Single Master Operations (FSMO) roles, also known as operations master roles

ROLE NAME Schema Master; SCOPE 1 per forest
DESCRIPTION Controls and handles updates/modifications to the Active Directory schema.

ROLE NAME Domain Naming Master; SCOPE 1 per forest
DESCRIPTION Controls the addition and removal of domains from the forest if present in root domain.

ROLE NAME PDC Emulator; SCOPE 1 per domain
DESCRIPTION PDC is short for Primary Domain Controller, which was the main domain controller used with Windows NT. The PDC emulator provides backwards compatibility for NT4 clients. It also acts as the primary server for password changes and as the master time server within the domain.

ROLE NAME RID Master (Relative ID Master); SCOPE 1 per domain
DESCRIPTION Allocates pools of unique identifiers to domain controlers for use when creating objects.

ROLE NAME infrastructure Master; SCOPE 1 per domain
DESCRIPTION Synchronizes cross-domain group membership changes. The infrastructure master cannot run on a global catalog server unless all DCs are also GCs.

29
Q

31
Q
  1. The local security database found on a member server is known as the ______ .
A

Security Accounts Manager (SAM)

The Security Accounts Manager (SAM) is a database file in Windows XP, Windows Vista and Windows 7 that stores users passwords. It can be used to authenticate local and remote users. Beginning with Windows 2000 SP4, Active Directory is used to authenticate remote users. SAM uses cryptographic measures to prevent forbidden users to gain access to the system.

Competency Assessment
Scenario 5-1: Designing Active Directory
You have ten sites throughout the country and five major departments. How would you design your Active Directory structure?

A

You can use one domain with two different approaches (depending on your management needs). One approach is to have five OUs for each department with OUs for sites inside each department or to have an OU for each department with OUs for each site in the department OUs. When creating OUs, you should try not to make it two deep.

50
Q

Competency Assessment
Scenario 5-2: Designing AD Physical Structure
How do you define how the domain controllers will replicate data to the other domain controllers?

A

You need to first define sites based on your IP subnets and you should place two or more domain controllers on each site. For larger sites that may have additional domain controllers, you define bridgeheads that will be used as the central point of replication between the sites.
