Frequently Asked DNS And Active Directory Interview Questions Part – 3
1.What is Active Directory Recycle Bin?
Active Directory Recycle bin is a feature of Windows Server 2008 AD. It helps to restore accidentally deleted Active Directory objects without using a backed up AD database,rebooting domain controller or restarting any services.
2.What is group nesting?
Adding one group as a member of another group is called ‘group nesting’. This will help for easy administration and reduced replication traffic.
3.What are the logical components of Active Directory?
Domains,Organizational Units,trees and forests are logical components of Active Directory.
4.Can you connect Active Directory to other 3rd-party Directory Services? Name a few options?
Yes,you can use dirXML or LDAP to connect to other directories. In Novell you can use E-directory.
5.How do you create a new application partition?
Use the DnsCmd command to create an application directory partition. To do this,use the following syntax: DnsCmd ServerName /CreateDirectoryPartition FQDN of partition
6.Difference between LDIFDE and CSVDE?
CSVDE is a command that can be used to import and export objects to and from the AD into a CSV-formatted file. A CSV (Comma Separated Value) file is a file easily readable in Excel. I will not go to length into this powerful command,but I will show you some basic samples of how to import a large number of users into your AD.
Of course,as with the DSADD command,CSVDE can do more than just import users. Consult your help file for more info. LDIFDE is a command that can be used to import and export objects to and from the AD into a LDIF-formatted file. A LDIF (LDAP Data Interchange Format) file is a file easily readable in any text editor,however it is not readable in programs like Excel.
The major difference between CSVDE and LDIFDE (besides the file format) is the fact that LDIFDE can be used to edit and delete existing AD objects (not just users),while CSVDE can only import and export objects.
7.What are the DS
* commands?
The following DS commands: the DS family built in utility .
1. DSmod – modify Active Directory attributes.
2. DSrm – to delete Active Directory objects.
3. DSmove – to relocate objects
4. DSadd – create new accounts
5. DSquery – to find objects that match your query attributes.
6. DSget – list the properties of an object
8.What are System State data contains?
1. Contains Startup files
2. Registry
3. Com + Registration Database
4. Memory Page file
5. System files
6. AD information
7. Cluster Service information
8. SYSVOL Folder
9.What is lost found folder in ADS?
It’s the folder where you can find the objects missed due to conflict. Ex: you created a user in OU which is deleted in other DC when replication happed ADS didn’t find the OU then it will put that in Lost Found Folder.
10.What Intrasite and Intersite Replication?
Intrasite is the replication with in the same site intersite the replication between sites.
11.Which is service in your windows is responsible for replication of Domain controller to another domain controller?
KCC generates the replication topology. Use SMTP / RPC to replicate changes.
12.What is LSDOU?
It’s group policy inheritance model,where the policies are applied toLocal machines,Sites,Domains and Organizational Units.
13.How to look at the Schema?
register schmmgmt.dll using this command c:\windows\system32>regsvr32 schmmgmt.dll Open mmc –> add snapin –> add Active directory schema name it as schema.msc Open administrative tool –> schema.msc
14.What is BridgeHead Server in AD?
A bridgehead server is a domain controller in each site,which is used as a contact point to receive and replicate data between sites. For intersite replication,KCC designates one of the domain controllers as a bridgehead server.
In case the server is down,KCC designates another one from the domain controller. When a bridgehead server receives replication updates from another site,it replicates the data to the other domain controllers within its site.
