What is the function of an LDAP query?
A LDAP query is a configurable search used to gather information from your directory server. It can be used to test whether certain data exists on the server.
no you cannot access my document folder
Switches operate at layer and Hubs operate at layer of OSI model?
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
What is the primary distinction between an active directory tree and an active directory forest?
The Domain is the core unit of logical structure in Active Directory. All objects which shares a common directory database, trust relationship with other domain and security policies is known as Domain. Each domain stores information only about the objects that belong to that domain.
All security polices and settings, such as administrative rights, security policies, and Access Control Lists (ACLs), do not cross from one domain to another, thus a domain administrator has full rights to set policies only within domain they belong to.
Domains provide administrative boundaries for objects; manage security for shared resources and a unit of replication for objects.
A Tree
Trees are collections of one or more domains that allow global resource sharing. A tree may consist of a single domain or multiple domains in a contiguous namespace. Adding a domain to a tree becomes a child of the tree root domain. Domain will be called as parent domain to which child domain is attached. A child domain can also have its multiple child domains. Child domain uses the name followed by parent domain name and gets a unique Domain Name System (DNS).
For example, if tech.com is the root domain, you can create one or more Child domains to tech.com such as north.tech.com and or south.tech.com. These "children" may also have child domains created under them, such as sales.north.tech.com.
The domains in a tree have two-way, Kerberos transitive trust relationships. A Kerberos transitive trust simply means that if Domain A trusts Domain B and Domain B trusts Domain C, then Domain A trusts Domain C. Therefore, a domain joining a tree immediately has trust relationships established with every domain in the tree.
A Forest
A forest is a collection of multiple trees that share a common global catalog, directory schema, logical structure, and directory configuration. Forest has automatic two-way transitive trust relationships. The very first domain you create in the forest is called the forest root domain.
Forests allow organizations to group their divisions which use different naming scheme, and may need to operate independently. But as an organization they want to communicate with the entire organization via transitive trusts, and share the same schema and configuration container.
What are the advantages of using directories?
There's really only one main advantage. It organizes everything. If there wasn't such thing as file directories then all the files would be a big screen and you would have to look for it.
What utility do you use to mark active directory objects as authoritative?
NTDS utility is used for this and this is found in admin pak
When you register an ATL server, you might get error 0x80040154 (hsows that the Class is not registered).
For DLLs, REGSVR32.exe returns this error. For EXEs, the call to _Module::RegisterServer(CComModule::RegisterServer) in _tWinMain() returns this error.
This means the ATL70.dll file is not installed/registered.
For Visual Studio 6.0 and earlier, the ATL runtime is contained in ATL.dll. If you use Visual Studio 6.0 or earlier, use ATL.dll instead of the later Visual Studio.NET version.
Solution for it
Install ATL70.dll (or ATL.dll for earlier versions of Visual Studio) in the Wind...Install ATL70.dll (or ATL.dll for earlier versions of Visual Studio) in the Windows\System or Winnt\System32 directory. You do not have to register ATL70.dll, however, you must register ATL.dll by using Regsvr32.exe. There are UNICODE and ANSI versions of ATL70.dll and ATL.dll. Install the appropriate version on the target operating system (that is, UNICODE for Microsoft Windows NT, and ANSI for Microsoft Windows 95 or Microsoft Windows 98).

Why was DNS Server service installed as part of the installation of Active Directory?
because it is the pre condition for active directory to work.
the work of dns is to find host( machine in the network ) with help of IP or hostname( computer name) and dns stores all the info about it
DNS makes ip addresses readable to us, for example instead of 172.63.187 we would type www.google.com........ it helps us out without it we'd have to memorize numbers to get web sites
In LDAP-compatible directories, a schema is the set of definitions of the kinds of objects and
object-related information that the directory can contain.
What is the purpose of a container in an LDAP-compatible NOS directory?
To organize similar objects for easier management
The Windows 2000 Active Directory is stored in what three files?
The Active Directory ESE database, NTDS.DIT, consists of the following tables: * Schema table
the types of objects that can be created in the Active Directory, relationships between them, and the optional and mandatory attributes on each type of object. This table is fairly static and much smaller than the data table. * Link table
contains linked attributes, which contain values referring to other objects in the Active Directory. Take the MemberOf attribute on a user object. That attribute contains values that reference groups to which the user belongs. This is also far smaller than the data table. * Data table
users, groups, application-specific data, and any other data stored in the Active Directory. The data table can be thought of as having rows where each row represents an instance of an object such as a user, and columns where each column represents an attribute in the schema such as GivenName.

What are the main benefits of the LDAP Active Directory?
The main benefits of using an active directory like LDAP Active Directory are many. One can use an active directory to allow for scheduling to made and updated in a timely manner.
What type of group can be used to grant permissions to objects located in any domain in a forest?
Global Groups
What is Block Policy inheritance?
Normally a policy setting will be enabled if a higher level or previous group policy sets it. This is inheriting the setting from a previous policy.
Using the block inheritance means that the setting will not be enabled from a previous policy.
Which layers in the OSI model are host to host layers?
Transport layer is known as the host-to-host layer.
Also data link layer is responsible for point-to-point or point-to-multipoint transport of data.

What port is used by Active Directory to direct search requests to a global catalog server?
The ports used by GC is as follows
GLOBAL CATALOG 3268
GLOBAL CATALOG 3269 https(secure)
What is an objects in Active Directory?
any entity in the AD is treated as and objects like user,computer, printer etc all the network resources are objects and each having some attributes.
Where can one find information on what is Active Directory?
Active Directory, a piece of software created by Microsoft in 1999 for the Windows 2000 operating system, information can be found on various Microsoft related websites.
