Question five. What Is The Global Catalog?

Answer :

A worldwide catalog server is a site controller. It is a grasp searchable database that containsinformation about every item in every domain in a wooded area. The international catalog carries acomplete duplicate of all objects in Active Directory for its host domain, and includes a partialreplica of all objects in Active Directory for each other area inside the wooded area.It has  vital features:Provides group membership information all through logon and authenticationHelps users locate assets in Active Directory

Question 6. What Is Rodcs?

Answer :

Read-Only Domain Controllers (RODCs) cope with some of the problems that are usually found in branch offices.These places might not have a DC, Or they could have a writable DC but no physicalsecurity to that DC, low network bandwidth, or insufficient know-how to assist that DC.

Question 7. What Are The Functionalities Of Rodcs?

Answer :

Functionality of RODCs:-

Read-Only DS database.
Uni-directional replication.
Credential caching.
Administrator role separation.

Question eight. What Are Fmso Roles? List Them.

Answer :

FSMO roles are server roles in a Forest.There are five forms of FSMO roles

Schema master.
Domain naming grasp.
Rid master.
PDC Emulator.
Infrastructure grasp.
Question 9. What Is Schema Master?

Answer :

The schema master area controller controls all updates and modifications to theschema. Once the Schema replace is complete, it is replicated from the schema master to allother DCs inside the listing. To update the schema of a wooded area, you should have get entry to to theschema master. There can be handiest one schema grasp inside the whole wooded area.

Question 10. What Is Domain Naming Master ?

Answer :

The area naming grasp domain controller controls the addition or removal of domainsin the woodland. This DC is the simplest one which can upload or cast off a site from the directory. Itcan also add or cast off go references to domains in external directories. There can beonly one area naming grasp in the whole wooded area.

Question eleven. What Is Infrastructure Master?

Answer :

Infrastructure Master:

When an object in one domain is referenced through any other item in any other domain, itrepresents the reference by using the GUID, the SID (for references to security principals), andthe DN of the item being referenced. The infrastructure FSMO role holder is the DCresponsible for updating an object’s SID and distinguished call in a pass-area objectreference. At any one time, there may be simplest one domain controller performing as theinfrastructure grasp in each domain.

Question 14. What Is Netdom?

Answer :

NETDOM is a command-line device that lets in management of Windows domains and trustrelationships. It is used for batch control of trusts, becoming a member of computers to domain names,verifying trusts, and comfy channels.

Question 15. What Is Kcc?

Answer :

The KCC is a integrated system that runs on all domain controllers and generates replicationtopology for the Active Directory forest. The KCC creates separate replication topologiesdepending on whether or not replication is happening within a website (intrasite) or among web sites(intersite). The KCC additionally dynamically adjusts the topology to deal with new area  controllers, area controllers moved to and from web sites, changing expenses and schedules, anddomain controllers which might be temporarily unavailable.

Question sixteen. What Is Repadmin?

Answer :

Repadmin.Exe: Replication Diagnostics ToolThis command-line device assists administrators in diagnosing replication problems betweenWindows area controllers.Administrators can use Repadmin to view the replication topology (from time to time referred to asRepsFrom and RepsTool) as visible from the perspective of every area controller. In addition,Repadmin may be used to manually create the replication topology (despite the fact that in regular practicethis need to not be important), to pressure replication activities among area controllers, and toview each the replication metadata and up-to-dateness vectors.

Question 17. What Is The Sysvol Folder?

Answer :

The Sysvol folder on a Windows domain controller is used to duplicate report-based information amongdomain controllers. Because junctions are used inside the Sysvol folder shape, Windows NTfile system (NTFS) model five.Zero is needed on domain controllers all through a Windowsdistributed report system (DFS) forest.This is a quote from Microsoft themselves basically the domain controller data stored in files likeyour group policy stuff is replicated thru this folder shape.

Question 18. What Is Dynamic Disk Storage?

Answer :

Dynamic storage is supported in Windows XP Professional, Windows 2000 and WindowsServer 2003. A disk initialized for dynamic garage is known as a dynamic disk. A dynamic diskcontains dynamic volumes, along with simple volumes, spanned volumes, striped volumes,mirrored volumes, and RAID-five volumes. With dynamic garage, you may perform disk andvolume control without the want to restart Windows.

Computer Science Engineering Interview Questions
Question 19. What Is Basic Disk Storage?

Answer :

Basic garage makes use of regular partition tables supported by way of MS-DOS, Microsoft Windows 95,Microsoft Windows ninety eight, Microsoft Windows Millennium Edition (Me), Microsoft WindowsNT, Microsoft Windows 2000, Windows Server 2003 and Windows XP. A disk initialized forBasic storage is called a fundamental disk. A basic disk includes primary volumes, together with primaryPartitions, extended partitions, and logical drives. Additionally, primary volumes includemultidisk volumes which might be created with the aid of using Windows NT four.0 or earlier, inclusive of volumesets, stripe sets, reflect units, and stripe sets with parity. Windows XP does now not supportthese multidisk simple volumes. Any extent sets, stripe sets, mirror sets, or stripe sets withparity ought to be sponsored up and deleted or transformed to dynamic disks earlier than you installWindows XP Professional.

Question 20. What Is Pdc Emulator?

Answer :

The PDC emulator is vital to synchronize time in an organization. Windows 2000/2003Includes the W32Time (Windows Time) time provider this is required by way of the KerberosAuthentication protocol. All Windows 2000/2003-primarily based computer systems inside an enterpriseUse a not unusual time. The cause of the time provider is to make sure that the Windows TimeService uses a hierarchical relationship that controls authority and does no longer allow loops toEnsure suitable commonplace time utilization.

Assertiveness Interview Questions
Question 21. What Is Rid Master?

Answer :

The RID grasp is answerable for processing RID pool requests from all area controllersin a selected area. When a DC creates a protection main item inclusive of a consumer orgroup, it attaches a completely unique Security ID (SID) to the object. This SID includes a website SID(the same for all SIDs created in a website), and a relative ID (RID) this is unique for eachsecurity predominant SID created in a domain. Each DC in a website is allocated a pool of RIDsthat it's far allowed to assign to the safety principals it creates. When a DC’s allotted RIDpool falls below a threshold, that DC troubles a request for additional RIDs to the area’sRID grasp. The area RID grasp responds to the request with the aid of retrieving RIDs from thedomain’s unallocated RID pool and assigns them to the pool of the soliciting for DC. At any  one time, there can be handiest one domain controller appearing as the RID master in the area.PDC Emulator.
