cloud?**\ Virtual Desktop Infrastructure (VDI). 16. **Name two fault-tolerance features supported by Windows Server 2012/R2.**\ RAID (Redundant Array of Independent Disks) and load balancing. 17. **What is the role of a domain controller?**\ A server that manages access to network resources, authenticates users, and enforces security policies in a domain. 18. **What is IP Address Management (IPAM) used for?**\ To monitor and manage DHCP and DNS servers and to audit IP address use. 19. **Describe the function of the Server Manager in Windows Server 2012/R2.**\ Provides a centralized interface for managing server roles, diagnosing issues, and configuring servers. 20. **What is the purpose of the Distributed File System (DFS) in Windows Server 2012/R2?**\ To simplify file access and management by allowing shared folders to be grouped under a single namespace. 21. **What is the difference between Datacenter Edition and Standard Edition in Windows Server 2012/R2?**\ Datacenter Edition allows for unlimited virtual instances, while Standard Edition allows only two. 22. **Which feature in Windows Server 2012/R2 is aimed at providing a streamlined installation for servers that do not require a GUI?**\ Server Core. 23. **Explain the function of the Remote Access role in Windows Server 2012/R2.**\ Allows a server to be configured as a VPN server or DirectAccess server for secure remote access. 24. **What is Dynamic Access Control in Windows Server 2012/R2?**\ A feature that provides more granular control over access to files based on user attributes and file properties. 25. **What are cmdlets in PowerShell?**\ Cmdlets are lightweight commands used in the PowerShell environment for various management tasks. **Chapter 2: Installing Windows Server 2012/R2**

address to a server?**\ To ensure consistent access to network services without changes in the server\'s address. 28. **What should be considered when planning a Windows Server 2012/R2 installation?**\ Hardware requirements, server roles, network protocols, and IP addressing. 29. **What is a read-only domain controller (RODC)?**\ A domain controller that holds a read-only copy of the Active Directory database. 30. **List three hardware considerations for installing Windows Server 2012/R2.**\ CPU architecture, amount of RAM, and disk subsystem capabilities. 31. **What are patches, and how are they applied in Windows Server 2012/R2?**\ Patches are updates that fix bugs and security issues, applied through Windows Update. 32. **What is the difference between a service pack and a patch?**\ A service pack is a collection of patches and updates, while a patch addresses specific issues. 33. **Why is it important to set the correct time zone during server installation?**\ It affects user authentication and scheduling of tasks. 34. **What is the role of the Server Core installation in reducing resource usage?**\ It minimizes system resources by removing
