Level 2 Windows Administrator interview questions ### Technical Questions 1. **What are the roles and responsibilities of a Windows Administrator?** - **Answer**: A Windows Administrator is responsible for managing, configuring, and maintaining Windows server environments. This includes user account management, system updates, patch management, monitoring system performance, troubleshooting issues, ensuring security, and providing technical support to users. 2. **Explain the process of Active Directory (AD) replication.** - **Answer**: AD replication is the process by which the changes made on one domain controller (DC) are synchronized with all other DCs in the domain or forest. This ensures consistency and reliability of the data. AD uses multi-master replication, meaning changes can be made on any DC and will be replicated to others. Replication can be intra-site (within the same site) or inter-site (between different sites), and it uses protocols like RPC over IP for intra-site and SMTP for inter-site replication. 3. **How do you create and manage Group Policies in Windows Server?** - **Answer**: Group Policies are created and managed using the Group Policy Management Console (GPMC). Policies can be applied to users and computers within an Active Directory environment to enforce security settings, software installations, scripts, and more. To create a GPO, open GPMC, right-click on the desired domain or OU, and select "Create a GPO in this domain, and link it here." Configure the settings by editing the GPO. 4. **What is the difference between NTFS and FAT32 file systems?** - **Answer**: NTFS (New Technology File System) and FAT32 (File Allocation Table 32) are two file systems used by Windows. NTFS supports larger file sizes and volumes, provides better security with file and folder permissions, and offers features like encryption, compression, and disk quotas. FAT32 is older, supports smaller file sizes (up to 4GB) and volumes (up to 32GB), and lacks the advanced features of NTFS. 5. **How do you back up and restore Active Directory?** - **Answer**: Backing up Active Directory involves using tools like Windows Server Backup to create a system state backup, which includes the AD database. Restoring AD can be done by booting into Directory Services Restore Mode (DSRM) and using the backup to restore the system state. It's crucial to perform regular backups and test the restoration process to ensure data integrity and availability.

Windows Administrator Level 2 (L2) position 1. **Explain Active Directory (AD) and its main components.** The main components of AD - **Domain Controllers:** Servers that host AD services and store directory data. - **Organizational Units (OUs):** Containers within a domain that can hold users, groups, and computers, helping to organize resources and apply policies. - **Groups:** Collections of users, computers, or other groups, primarily used for assigning permissions. - **Forest:** The top-level container in an AD infrastructure that contains one or more domains. - **Schema:** Defines objects and their attributes within AD. - **Global Catalog:** A distributed data repository that contains a searchable, partial representation of every object in every domain in a multi-domain AD environment. ### 2. **What is the purpose of Group Policy in Windows Server?** **Answer:** Group Policy is used to control the working environment of user accounts and computer accounts. It provides centralized management and configuration of operating systems, applications, and users' settings. Group Policy is primarily used to enhance security and manage various settings across a network efficiently. ### 3. **How do you backup and restore Active Directory?** **Answer:** To backup Active Directory, you typically use Windows Server Backup. You can perform a system state backup which includes AD database, SYSVOL, registry, and other critical system components. To restore AD, you can use the backup taken and perform a restore operation using Windows Server Backup. In case of a significant failure, you may need to perform an authoritative or non-authoritative restore. ### 4. **Explain the difference between authoritative and non-authoritative restore.** **Answer:** - **Authoritative Restore:** Used when you need to restore specific AD objects (such as users, groups, or entire OUs) to a previous state and ensure that these restored objects are replicated to all other domain controllers. This is done using the `ntdsutil` tool. - **Non-Authoritative Restore:** Used to restore the AD database to the state it was in when the last backup was taken. After a non-authoritative restore, the domain controller will receive updates from other domain controllers to bring it up-to-date. ### 5. **What are FSMO roles and why are they important?** **Answer:** FSMO (Flexible Single Master Operations) roles are specialized domain controller tasks in an AD environment. They are: - **Schema Master:** Controls all updates and modifications to the schema. - **Domain Naming Master:** Responsible for changes to the forest-wide domain name space. - **RID Master:** Allocates pools of RIDs (Relative Identifiers) to domain controllers for creating objects. - **PDC Emulator:** Acts as a primary domain controller, managing password changes and time synchronization. - **Infrastructure Master:Maintains references to objects in other domain ->Continue
