Interview Questions and Answers

Common Active Directory troubleshooting steps include checking DNS configuration, verifying network connectivity, examining event logs, and using tools like `dcdiag` and `repadmin` to diagnose replication and other problems.

Azure Active Directory (Azure AD) is a cloud-based identity and access management service. While it shares the "Active Directory" name, its a distinct service from on-premises Active Directory. Azure AD is designed for cloud applications and services, while on-premises Active Directory is designed for managing resources within a local network.

DNS (Domain Name System) is used to resolve hostnames to IP addresses. Active Directory relies heavily on DNS for locating Domain Controllers and other resources within the domain. Proper DNS configuration is crucial for Active Directory to function correctly.

You can join a computer to a domain through the System Properties in Windows, by changing the computers workgroup to a domain and providing the necessary credentials.

Some best practices include using strong passwords, implementing the principle of least privilege, regularly auditing Active Directory, keeping Domain Controllers patched and updated, and implementing account lockout policies.

The Functional Level determines the Active Directory features that are available within a domain or forest. Its based on the oldest Windows Server operating system running as a Domain Controller in that environment.

You can create a new user account using the Active Directory Users and Computers (ADUC) console, the Active Directory Administrative Center (ADAC), or using PowerShell cmdlets like `New-ADUser`.

You can reset a users password using ADUC, ADAC, or PowerShell. Youll typically need administrative privileges to perform this action.

LDAP (Lightweight Directory Access Protocol) is a protocol used to access and modify directory services like Active Directory. Active Directory uses LDAP as its primary protocol.

There are two main types of groups in Active Directory: Security Groups and Distribution Groups. Security Groups are used to grant permissions to resources, while Distribution Groups are used for email distribution lists.

The Active Directory Schema defines the structure of the Active Directory database, including the object classes and attributes that can be stored. It defines what types of objects can be created and what information they can hold.

Active Directory authentication typically uses the Kerberos protocol. When a user logs in, their credentials are sent to a Domain Controller, which verifies their identity and grants access to resources within the domain.

A Forest is the highest level of logical structure in Active Directory. It is a collection of one or more domains that share a common schema, configuration, and global catalog.

A Global Catalog Server is a Domain Controller that holds a partial replica of all objects in the forest. It allows users to search for objects in any domain within the forest without having to query each domain separately.

A Domain is a logical grouping of users, computers, and other resources that share a common Active Directory database and security policies. It represents a single administrative unit.

An Organizational Unit (OU) is a container within a domain that allows you to organize users, computers, and other OUs into logical groups. OUs are used for delegation of administrative control and applying Group Policies.

Group Policy is a feature of Active Directory that allows administrators to centrally manage user and computer settings. Its used to define security policies, application settings, desktop configurations, and more.

The main components of Active Directory include Domain Controllers, Domains, Organizational Units (OUs), Sites, Group Policies, and Active Directory Schema.

A Domain Controller is a server that holds a writable copy of the Active Directory database. It authenticates users, enforces security policies, and manages resources within the domain.

Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is used to manage users, computers, groups, security policies, and other resources in a network.

Active Directory is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services.

Centralized resources and security administration.
- Single logon for access to global resources.
- Simplified resource location.

A domain is defined as a logical group of network objects (computers, users, devices) that share the same Active Directory database. A tree is a collection of one or more domains and domain trees in a contiguous namespace, and is linked in a transitive t

The Active Directory structure is comprised of three main components: domains, trees, and forests.

Yes, you can connect to 3rd party directories like E-directory from Novell or NDS (Novel directory System), SAP, Domino etc with the help of MIIS (MicrosoftIdentity Integration Server)/

Online Defragmentation – Windows Server 2000 introduced a method that runs in certain intervals automatically to defragment the Active Directory database. It is part of active directory garbage collection process. It optimizes the data storage and reclaim

Enterprise Admin: In Enterprise Admin groups, members have full rights over all of the domains in the forest.

Domain Admin groups: In Domain Admin groups, members have complete control of the domain.

LDAP and Kerberos are the default protocols used in directory devices.
