  • Knowledge of Active Directory and Group Policy
  • Experience in server and network infrastructure maintenance and troubleshooting
  • Understanding of Virtualization technologies such as VMware and Hyper-V
  • Excellent communication and interpersonal skills
  • 2. How do you manage user accounts on Windows Active Directory?

    The answer to this question can vary based on the interviewee's experience and the organization they have previously worked for. However, you can highlight the necessary steps involved in managing accounts with Active Directory.

  • Creating, modifying, or deleting user accounts, computer accounts, and groups.
  • Managing access controls and permissions at individual or group levels.
  • Resetting user passwords and account attributes like expiration and domains.
  • Configuring group policies defining security policies for your organization.
  • 3. How do you ensure the security of Windows servers and networks?

    Securing a Windows environment should be a top priority for system administrators. In this answer, one must be aware of best practices to secure Windows servers and networks to ensure the organization's system is well-protected.

  • Ensuring software and hardware firewalls are in place and running.
  • Using virus protection software on all servers and endpoints.
  • Regular maintenance and patching of the system to keep it up-to-date.
  • Implementing intrusion detection and prevention methods.
  • Limiting access to the server and network devices using procedures like user access controls, passwords, and biometrics.
  • 4. Explain the difference between incremental and differential backups.

    System administrators perform backup operations on a regular basis. Therefore, they must be aware of different types of backups and their advantages and disadvantages.

  • Incremental Backup: This type of backup only backs up changed files since the previous backup. Hence, it is faster and requires less storage space compared to other backup types.
  • Differential Backup: This type of backup only backs up files that have changed since the last full backup. As a result, it consumes more space, and backups take more time to complete.
  • 5. What is a domain controller, and what role does it play in Active Directory?

    A Domain Controller is a server running the Active Directory Domain Service. It is responsible for authenticating domain users, authorizing users to access domain resources, and coordinating domain management.

  • The primary functions of a domain controller include:
  • Authentication and authorization of domain users and computers
  • Enabling centralized management of network resources such as user accounts, security policies, and communication protocols.
  • Time synchronization within Active Directory to ensure all servers and workstations are consistent with one another.
  • 6. What are the steps involved in setting up a DHCP server?

    The Dynamic Host Configuration Protocol (DHCP) is used to automatically assign IP addresses to devices on a network. Setting up a DHCP server requires a few simple steps.

  • Install DHCP server role from the server manager.
  • Create a new scope for the IP address range you want to assign to devices.
  • Configure scope options such as default gateway, DNS server, and lease duration.
  • Activate the scope for DHCP clients to start receiving IP addresses automatically.
  • 7. What is a Server Cluster, and why is it important?

    A server cluster is a collection of servers working together to provide increased availability and reliability of services. System administrators must have basic knowledge about server clusters and their role.

  • The primary purposes of server clusters include:
  • Load balancing and failover: When one server fails or cannot take additional load, other servers in the cluster take over the workload.
  • Increased uptime: IIf a server or a component fails, cluster services continue to operate with minimal to zero downtime.
  • Lower costs: A server cluster can reduce hardware and software costs compared to using separate servers.
  • 8. What is PowerShell? How is it useful for system administrators?

    PowerShell is a command-line interface used to automate Windows system administration tasks. It's a built-in tool for Windows systems and helps system administrators work more efficiently.

  • Some of the benefits of using PowerShell include:
  • Automating routine administrative tasks, such as backup or user account management.
  • Reducing administrative errors using automation and script-based procedures.
  • Improving productivity and efficiency.
  • 9. What is the difference between a physical server and a virtual server?

    In a nutshell, a physical server is a computer system that runs an operating system, while a virtual server is a software-based emulation of a physical server.

  • Physical Server:
  • Runs on dedicated hardware.
  • Requires routine maintenance such as updating BIOS or adding new hardware.
  • Generally more expensive than virtual servers.
  • Virtual Server:
  • Runs as an application or service on an existing physical server.
  • Allows multiple virtual servers to run on a single physical server with a shared hardware resource.
  • Quick to create, move, and destroy.
  • 10. What configuration management tools are you familiar with?

    Configuration management tools help in managing IT infrastructure and automating tasks. As a Windows SysAdmin, you'd want to be familiar with the most popular tools used for configuration management.

  • Some of the commonly used configuration management tools are:
  • Ansible: Allows automating and streamlining IT tasks.
  • Chef: Facilitates scalability and configuration automation with the full policy model.
  • Puppet: Implements a platform-agnostic approach to automate system administration.
  • Conclusion:

    Preparing well for an IT interview shows a candidate's dedication to mastering their craft. Now that you've familiarized yourself with the top Windows System Administrator interview questions and their answers, you can go into your interview confidently.
