There is huge demand for this technology in the market. Opportunities are everywhere for this technology. Good knowledge on how the process is done will fetch you the job. Wisdomjobs framed Windows Administration interview questions and answers to make it easier for your interview preparation. Question 1. What Is Active Directory? Answer : Tree is a hierarchical arrangement of windows Domain that share a contiguous name space. It provides authentication and authorization mechanisms as well as a framework within which other related services can be deployed.

Question 4. Answer : Forest consists of multiple Domains trees. The Domain trees in a forest do not form a contiguous name space however share a common schema and global catalog GC. Answer : Active directory schema is the set of definitions that define the kinds of object and the type of information about those objects that can be stored in Active Directory. Question 7. Question 8.

Question 9. Question Answer : NTDS. Log EDB. Che Res1. Log and from log file to database, EDB. Che used to track the database update from log file, to know what changes are copied to database file. Log: EDB. Log is the transaction log file when EDB.

Log is full, it is renamed to EDB Num. Che: EDB. Che is the checkpoint file used to trace the data not yet written to database file this indicate the starting point from which data is to be recovered from the log file in case if failure. What Is Active Directory Partitions? Answer : Active Directory partition is how and where the AD information logically stored.

Answer : Schema Configuration Domain Application partition. Answer : Schema Partition — It store details about objects and attributes. Replicates to all domain controllers in the Forest. Configuration Partition — It store details about the AD configuration information like, Site, site-link, subnet and other replication topology information.

Domain Partitions — object information for a domain like user, computer, group, printer and other Domain specific information. Replicates to all domain controllers within a domain. Application Partition — information about applications in Active Directory. Answer : You can only configure the Application partition manually to use with AD integrated applications. Answer : System state backup will backup the Active Directory, NTbackup can be used to backup active directory.

Active Directory Restores Types? Answer : Authoritative restore Non-authoritative restore. Non-authoritative Restore Of Active Directory? Answer : Non-authoritative restore is restore the domain controller to its state at the time of backup, and allows normal replication to overwrite restored domain controller with any changes that have occurred after the backup.

After system state restore, domain controller queries its replication partners and get the changes after backup date, to ensure that the domain controller has an accurate and updated copy of the Active Directory database. Non-authoritative restore is the default method for restoring Active Directory, just a restore of system state is non-authoritative restore and mostly we use this for Active Directory data loss or corruption.

How Perform A Non-authoritative Restore? Answer : Just start the domain controller in Directory Services Restore Mode and perform system state restore from backup. Authoritative Restore Of Active Directory?

Answer : An authoritative restore is next step of the non-authoritative restore process. We have do non-authoritative restore before you can perform an authoritative restore. The main difference is that an authoritative restore has the ability to increment the version number of the attributes of all objects or an individual object in an entire directory, this will make it authoritative restore an object in the directory.

In a non-authoritative restore, after a domain controller is back online, it will contact its replication partners to determine any changes since the time of the last backup. However the version number of the object attributes that you want to be authoritative will be higher than the existing version numbers of the attribute, the object on the restored domain controller will appear to be more recent and therefore, restored object will be replicated to other domain controllers in the Domain.

Answer : You can authoritatively restore only objects from configuration and domain partition. Authoritative restores of schema-naming contexts are not supported. What Are Group Policies? Answer : Group policies specify how programs, network resources, and the operating system work for users and computers in an organization.

They are collections of user and computer configuration settings that are applied on the users and computers not on groups. For better administration of group policies in the Windows environment, the group policy objects GPOs are used.

Answer : Group policy object GPO is a collection of group policy settings. It can be created using a Windows utility known as the Group Policy snap-in. GPO affects the user and computer accounts located in sites, domains, and organizational units OUs. The local GPO affects only the computer on which it is stored. By default, only Security Settings nodes are configured. The rest of the settings are either disabled or not enabled. What Is Non-local Policy? The non-local GPOs must be linked to a site, domain, or organizational unit OU to apply group policies to the user or computer objects.

Multiple GPOs. Answer : The local group policy object is applied first Then, the group policy objects linked to sites are applied If multiple GPOs exist for a site, they are applied in the order specified by an administrator GPOs linked to the domains are applied in the specified order Finally, GPOs linked to OUs are applied The OU group policy objects are set from the largest to the smallest organizational unit, i.

By default, a policy applied later overwrites a policy that was applied earlier. Hence, the settings in a child OU can override the settings in the parent OU. Group policy settings are cumulative if they are compatible with each other. In case they conflict with each other, the GPO processed later takes precedence. What Is No Override?

Question 40 Explain Global Catalog? Answer:- A global catalog server is a domain controller that, in addition to its full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest Global group’s membership is limited to accounts from the same domain.

The membership is replicated in its own domain only. Universal group’s memership is limited to accounts from the same forest. The membership is replicated across the forest Read More Answers. Answer:- Replmon Read More Answers. Question 42 What is the the Directory Partitions? The schema partition is stored on all domain controllers in a forest. It contains definitions of all objects and attributes that can be created in the directory.

Configuration Partition: There is only one configuration partition per forest. Domain Partition: Many domain partitions can exist per forest. Domain partitions are stored on each domain controller in a given domain. A domain partition contains information G about users, groups, computers, and organizational units. Application Partition: It stores information about applications in Active Directory. It is replicated only to specific domain controllers. Answer:- ntdsutil – type roles – connections – connect servername – q – type seize role – at the fsmo maintenance prompt – type seize rid master lG Read More Answers.

Answer:- in It is a role that only one DC can or should hold at any given time within its boundary. The schema master domain controller controls all updates and modifications to the schema. Once the Schema update is complete, it is replicated from the schema master to all other DCs in the directory. It controls the addition or removal of domains in the forest. The PDC emulator is necessary to synchronize time in an enterprise.

Updates group membership information when users from other domains are moved or renamed. If the Infrastructure Master runs on a Global Catalog server it will stop updating object information because it does not contain any references to objects that it does not hold.

Bridgehead server – A domain controller that is used to send replication information to one or more other sites DHCP Superscope: A rage of IP address that span several subnets. The DHCP server can assign these address to clients that are on several subnets. A stub zone is used to resolve names between separate DNS namespaces.

This table is fairly static and much smaller than the data table.

DIT Link table? Answer:- Link Table contains linked attributes, which contain values referring to other objects in the Active Directory. Take the Member Of 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. DIT Data table? Question 59 How many types of Active Directory data?

Replicates to all DCs within a domain. The object portion becomes part of GC. The attribute values only replicates within the domain. C This is reserved transaction log files of 20 MB 10 MB each which provides the transaction log files enough room to shutdown if the other spaces are being used. Answer:- M Garbage Collection is a process that is designed to free space within the Active Directory database.

This process runs independently on every DC with a default lifetime interval of 12 hours. Question 63 List the main steps of Garbage collection process? Tombstones are remains of objects that have been previously deleted.

Answer:- Online Defragmentation method that runs as part of the garbage collection process. The only advantage to this method is that the server does not need to be taken offline for it to run. However, this method does not shrink the Active Directory database file Ntds. Question 65 What is Schema information in Active Directory? Replicates to all DCs. Static in nature. Answer:- Configuration data about forest and trees.

Static as your forest is. This approach requires that the ADS database be started in repair mode. The advantage to this method is that the database is resized, unused space is removed, and the size is reflected by the Ntds. The database file cannot be compacted while Active Directory is mounted. To defrag ntds. Compact to D:DbBackup You must specify a directory path and if the path name has spaces, the command will not work unless you use quotation marks: in Quit till you reach the command prompt A new compacted database named Ntds.

Copy the new ntds. You have successfully compacted the Active Directory database. Question C Define EDB. Answer:- This is the transaction log file 10 MB. When EDB. Where nnnn is the increasing number starting from 1. Answer:- This is the checkpoint file used to track the data not yet written to database file. This indicates the starting point from which data is to be recovered from the log file, in case of failure.

Answer:- A forest consists of multiple domain trees. The domain trees in a forest do not form a contiguous namespace but share a common schema and GC. The forest root domain is the first domain created in the forest. The root domains of all domain trees in the forest establish transitive trust relationships with the forest root domain. This is necessary for the purposes of establishing trust across all the domain trees in the forest.

This can be useful in, for example, companies with independent divisions that must each maintain their own DNS names. Question 72 Define domain Trees in Active Directory? Answer:- Tree is a hierarchical arrangement of W2K domains that share a contiguous name space.

The first domain in a domain tree is called the root domain. A domain immediately above another domain in the same domain tree is referred to as the parent of the child domain. The name of the chills domain is combined with its parent domain to form its DNS name. Every child domain has a two two-way, transitive trust relationship with its parent domain Because these trust relationships are two-way and transitive, a Windows domain newly created in a domain tree or forest immediately has trust relationships established with every other Windows domain in the domain tree or forest.

These trust relationships allow a single logon process to authenticate a user on all domains in the domain tree or forest. This does not necessarily mean that the authenticated user has rights and permissions in all domains in the domain tree.

Because a domain is a security boundary, rights and permissions must be assigned on a per-domain basis. Answer:- Attributes are defined separately from classes.

For example, the Description attribute is used ba in many classes, but is defined once in the schema, assuring consistency. Question 74 lG Define Active Directory schema? Answer:- The Active Directory schema is the set of definitions that defines the kinds of objects, and the types of information about those objects, that can be stored in Active Directory.

The definitions are themselves stored as objects so that Active Directory can manage the schema objects with the same object management operations used ui for managing the rest of the objects in the directory. There are two types of definitions in the schema: attributes and classes. Answer:- in Site consists of one or more IP subnets connected by a high speed link.

Wide area networks should employ multiple sites for efficiently handling servicing requests and reducing replication traffic. Sites map the physical structure of your network whereas domains generally map the logical structure of your organization.

Active Directory Sites and Services allow you to specify site information. Active Directory uses this information to determine how best to use available network resources. Answer:- Active Directory Sites and Services allow you to specify site information. Active Directory uses this information to determine how best to use available network O resources.

Answer:- Classes, also referred to as object classes; describe the possible directory objects that can be created. Each class is a collection of attributes. When you create an object, the attributes store the information that describes the object.

The User class, for example, is composed of many attributes, including Network Address, Home Directory, and so on. Every object in Active Directory is an instance of an object class. Question 78 Define Service requests in Active Directory? Answer:- When a client requests a service from a domain controller, it directs the request to a domain controller in the same site. Selecting a domain controller that is well-connected to the client makes handling the request more efficient.

Answer:- GC is created automatically on the first DC in the forest. It stores a full replica of all objects in the directory for its host domain and a partial replica of all objects of every other domain in the forest. The replica is partial because it stores only some attributes for each objects. Question 80 List the GC key directory roles? Answer:- Site streamlines replication of directory information and reduces replication traffic. A client determines it is in when it is turned on, so its site location will often be dynamically updated.

A domain controller’s site location is established by which site its Server object belongs to in the directory, so its site location will be consistent unless the domain controller’s Server object is intentionally moved to a different site.

Question 82 Define the global catalog key directory roles? If there is only one domain controller in the domain, the domain controller and the global catalog are the same server.

If there are multiple domain controllers in the network, the global catalog is hosted on the domain controller configured as such. If a global catalog is not available when a user initiates a network ui logon process, the user is only able to log on to the local computer.

It stores a full replica of all objects in the directory for its host domain and a partial replica of all objects contained in the directory of every other domain in the forest. The replica is partial because it stores some, but not all, of the in property values for every object in the forest.

C Answer:- The global catalog is designed to respond to queries about objects anywhere in the forest with maximum speed and minimum network traffic.

The main difference is that an authoritative restore has the ability to increment the version number of the attributes of all objects or an individual object in an entire directory, this will make it authoritative restore an object in the directory.

In a non-authoritative restore, after a domain controller is back online, it will contact its replication partners to determine any changes since the time of the last backup. However the version number of the object attributes that you want to be authoritative will be higher than the existing version numbers of the attribute, the object on the restored domain controller will appear to be more recent and therefore, restored object will be replicated to other domain controllers in the Domain. Answer : You can authoritatively restore only objects from configuration and domain partition.

Authoritative restores of schema-naming contexts are not supported. What Are Group Policies? Answer : Group policies specify how programs, network resources, and the operating system work for users and computers in an organization. They are collections of user and computer configuration settings that are applied on the users and computers not on groups. For better administration of group policies in the Windows environment, the group policy objects GPOs are used.

Answer : Group policy object GPO is a collection of group policy settings. It can be created using a Windows utility known as the Group Policy snap-in.

GPO affects the user and computer accounts located in sites, domains, and organizational units OUs. The local GPO affects only the computer on which it is stored. By default, only Security Settings nodes are configured.

The rest of the settings are either disabled or not enabled. What Is Non-local Policy? The non-local GPOs must be linked to a site, domain, or organizational unit OU to apply group policies to the user or computer objects. Multiple GPOs. Answer : The local group policy object is applied first Then, the group policy objects linked to sites are applied If multiple GPOs exist for a site, they are applied in the order specified by an administrator GPOs linked to the domains are applied in the specified order Finally, GPOs linked to OUs are applied The OU group policy objects are set from the largest to the smallest organizational unit, i.

By default, a policy applied later overwrites a policy that was applied earlier. Hence, the settings in a child OU can override the settings in the parent OU.

Group policy settings are cumulative if they are compatible with each other. In case they conflict with each other, the GPO processed later takes precedence.

What Is No Override? Block Policy Inheritance? Answer : The following are the exceptions with regard to the above-mentioned settings:. It deflects all group policy settings that reach the site, domain, or OU from the object higher in the hierarchy. The group policies are inherited from parent to child within a domain. They are not inherited from parent domain to child domain. Answer : A policy setting is configured Enabled or Disabled for a parent OU, and the same policy setting is not configured for its child OUs.

Incompatible policy settings from the parent OU are not inherited. What Is Security Filtering? Filtering Scope Of Gpos? Answer : Although GPOs are linked to the site, domain, or OUs, and they cannot be linked to the security groups directly, applying permissions to the GPO can filter its scope.

What Is Netlogon Folder? After the domain controller restarts, it replicates the any necessary changes, bringing it up-to-date with the other domain controllers within the domain. After the necessary configurations have been made, Active Directory marks the local SYSVOL as authoritative and it is replicated to the other domain controllers within the domain.

What Is Dns Scavenging? What Is Dynamic Dns Record? This question allows interviewers to see how you react when put on the spot, which happens to administrative assistants all the time, and how confident you are in your abilities.

A: Switching or transferring roles in an Active Directory can be made with the use of Ntdsutil. It also resolves names for DNS namespaces, thing required when names must be resolved from two different DNS namespaces. Q: What main file is used for Active Directory backup and how it is made? A: Active Directory backup is made using NTbackup utility.

The backup is made once with the system state and they are restored also together because they depend on each other. The system state has different components like:. Q: Does a windows administrator have to be critical? A: Yes and I can explain how. Q: In what way is forward lookup zone different from the reverse lookup zone in NDS?

A: There is one difference between these two: the forward lookup means name to IP and reverse lookup means IP to name. Q: As a system administrator can you make backup and recovery of data?
