Microsoft AZ-800: Administering Windows Server Hybrid Core Infrastructure

Last checked October 22, 2026 against the official Microsoft exam page.

1. Question 1Deploy and manage Active Directory Domain Services (AD DS) in on-premises and cloud environments

   Which FSMO role exists only once in an entire Active Directory forest?

   1. AThe PDC emulator, which handles time synchronization and password change processing for the domain
   2. BThe schema master, which is the only domain controller that can make changes to the forest schema
   3. CThe RID master, which allocates pools of relative identifiers to domain controllers in the domain
   4. DThe infrastructure master, which updates references to objects in other domains of the forest
   Show answer and explanationHide answer

   Correct answer: B

   The schema master is a forest-wide role, held by a single domain controller, that is the only place schema changes can be made. The PDC emulator, RID master, and infrastructure master are domain-wide roles that exist once in each domain.

2. Question 2Manage storage and file services

   What does Data Deduplication do on a Windows Server volume?

   1. AIt copies every file on the volume to a second volume in the same server so that the data is protected against loss
   2. BIt reduces the storage that a volume uses by identifying and storing duplicate chunks of data only once
   3. CIt removes the file names from the volume so that the files can be accessed only by using their numeric identifiers
   4. DIt deletes the files that have not been opened for a year, which frees space for the newer data on the server
   Show answer and explanationHide answer

   Correct answer: B

   Data Deduplication removes duplicate chunks of data on a volume so that identical data is stored once, which saves space. Copying files, removing names, and deleting old files are not what deduplication does.

3. Question 3Manage virtual machines and containers

   Which Hyper-V feature allows a virtual machine to use a physical graphics processor from the host through partitioning?

   1. AEnhanced session mode, which improves the redirection of the local display and devices during a remote session
   2. BShielded VMs, which protect the virtual machine's disks and memory from inspection by the administrators of the host
   3. CDynamic memory, which adjusts the memory assigned to a virtual machine based on the demand from its running workload
   4. DGPU partitioning, which shares a physical graphics processor among virtual machines by assigning partitions to them
   Show answer and explanationHide answer

   Correct answer: D

   GPU partitioning assigns parts of a physical graphics processor to virtual machines. Shielded VMs, dynamic memory, and enhanced session mode address security, memory, and remote session features.

4. Question 4Implement and manage an on-premises and hybrid networking infrastructure

   What does a DHCP scope define on a DHCP server?

   1. AThe schedule on which the server backs up its database to the storage device, which runs during the night each week
   2. BThe list of the printers that are available to the users on the subnet, together with the names of their drivers
   3. CThe password policy that applies to the user accounts that sign in to the computers on the subnet each working day
   4. DA pool of IP addresses and the options, such as the default gateway and DNS server, that are given to clients on a subnet
   Show answer and explanationHide answer

   Correct answer: D

   A DHCP scope is a pool of addresses and configuration options for a subnet. Printer lists, password policies, and backup schedules are not part of a scope.

5. Question 5Manage Windows Servers and workloads in a hybrid environment

   Which browser-based tool provides a central interface for managing Windows Servers, including servers connected to Azure?

   1. AWindows Admin Center, which manages Windows Server through a browser and can connect to servers that are also in Azure
   2. BThe Windows Event Viewer, which displays the logs of a single server on the local machine and cannot be used remotely
   3. CThe Windows Media Player, which plays audio and video files on the client computer used by the administrator each day
   4. DThe Windows Mail application, which sends and receives email messages for the users who sign in to the workstation
   Show answer and explanationHide answer

   Correct answer: C

   Windows Admin Center is the browser-based management tool that also works with Azure-connected servers. Event Viewer is local, while Media Player and Mail are user applications unrelated to server management.
