Interview Question & Answer MCSE & CCNA

MCSE - Windows: Active Directory, Functional Levels, FSMO Roles

What is RODC? Active Directory Recycle Bin, KCC, Sysvol

35.Do we use clustering in Active Directory? Why?

No one installs Active Directory in a cluster. There is no need of clustering a domain controller. Because Active Directory provides total redundancy with two or more servers

36.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 backedup AD database, rebooting domain controller or restarting any services

37.What is RODC? Why do we configure RODC?

Read only domain controller (RODC) is a feature of Windows Server 2008 Operating System. RODC is a read only copy of Active Directory database and it can be deployed in a remote branch office where physical security cannot be guaranteed. RODC provides more improved security and faster log on time for the branch office

38.How do you check currently forest and domain functional levels? Say both GUI and Command line.

 To find out forest and domain functional levels in GUI mode, open ADUC, right click on the domain name and take properties. Both domain and forest functional levels will be listed there. TO find out forest and domain functional levels, you can use DSQUERY command.

39. Explain Knowledge Consistency Checker (KCC)

KCC can be expanded as Knowledge Consistency Checker. It is a protocol process running on all domain controllers, and it generates and maintains the replication topology for replication within sites and between sites.

40. What are the tools used to check and troubleshoot replication of Active Directory?

We can use command line tools such as repadmin and dcdiag. GUI toolREPLMON can also be used for replication monitoring and troubleshooting.

41. What is SYSVOL folder used for?

SYSVOL is a folder exits on each domain controller, which contains Active Directory related files and folders. SYSVOL mainly stores important elements of Group Policy Objects and scripts, and it is being replicated among domain controllers using File Replication Service (FRS).
