Question 381. Which Active Directory tool can verify whether a domain controller can register required DNS records?

1. Dcdiag
2. Robocopy
3. Diskpart
4. FSRM

Correct Answer: 1. Dcdiag

Explanation:

Dcdiag includes diagnostic tests that can help administrators identify problems affecting domain controllers, including issues involving DNS registration and Active Directory connectivity. DNS health is particularly important because Active Directory depends heavily on DNS to locate domain controllers and directory services. If required DNS records are missing or incorrectly registered, authentication and replication-related operations can be affected. Administrators can use Dcdiag tests to investigate domain controller configuration and DNS-related conditions. Robocopy is designed for file copying, Diskpart manages disks and partitions, and FSRM manages file-server storage policies. Therefore, Dcdiag is an appropriate diagnostic utility when verifying domain-controller DNS registration and related health conditions.

Question 382. Which command displays a summary of Active Directory replication failures across domain controllers?

1. nslookup /summary
2. repadmin /replsummary
3. dcdiag /dns
4. ipconfig /displaydns

Correct Answer: 2. repadmin /replsummary

Explanation:

The repadmin /replsummary command provides a summarized view of Active Directory replication health across domain controllers. It can help administrators quickly identify servers experiencing replication failures and review statistics associated with replication attempts. This is useful when troubleshooting situations where directory information is inconsistent between domain controllers. The command does not replace detailed investigation, but it provides a convenient starting point for identifying problematic domain controllers. Nslookup is used for DNS queries, Dcdiag performs broader domain-controller diagnostics, and Ipconfig displays local DNS cache information with the appropriate switch. Therefore, repadmin /replsummary is the command specifically designed to summarize Active Directory replication failures.

Question 383. Which Windows Server service should be used to centrally approve and distribute Microsoft updates to servers?

1. DNS Server
2. DHCP Server
3. Windows Server Update Services
4. File Server Resource Manager

Correct Answer: 3. Windows Server Update Services

Explanation:

Windows Server Update Services, or WSUS, allows organizations to centrally manage and distribute Microsoft updates to supported Windows systems. Administrators can synchronize update metadata, review available updates, approve selected updates, and configure client computers to obtain approved updates from the organization’s WSUS infrastructure. This can provide greater control over update deployment than allowing every server to independently retrieve updates from Microsoft. DNS Server handles name resolution, DHCP Server provides network configuration, and FSRM manages file-server storage policies. Therefore, when an organization needs centralized approval and distribution of Microsoft updates to Windows Server systems, WSUS is the appropriate technology.

Question 384. Which WSUS capability allows administrators to prevent a specific update from being installed?

1. Update approval
2. DNS delegation
3. DHCP reservation
4. File screening

Correct Answer: 1. Update approval

Explanation:

WSUS update approval provides administrators with control over which updates are made available to managed clients. Administrators can approve updates for specific computer groups or decline updates that should not be deployed. This allows organizations to establish testing and deployment procedures before distributing updates broadly. For example, updates can first be evaluated in a test group and then approved for production systems after validation. DNS delegation manages DNS authority, DHCP reservations provide predictable client addresses, and file screening controls file types on a file server. Therefore, update approval is the WSUS capability that allows administrators to control whether a particular update is deployed to managed computers.

Question 385. Which Windows Server feature can automatically install approved updates according to configured maintenance schedules?

1. Windows Admin Center
2. WSUS
3. DFS Namespace
4. Storage Replica

Correct Answer: 2. WSUS

Explanation:

WSUS can centrally manage the distribution of approved Microsoft updates to Windows clients and servers. Administrators can configure computer groups, update approvals, client settings, and deployment schedules so that approved updates are obtained from the organization’s update infrastructure. Actual installation timing can also depend on Windows Update client policies and maintenance settings configured on the target systems. Windows Admin Center provides broader server administration, DFS Namespace organizes distributed file shares, and Storage Replica replicates storage volumes. Therefore, WSUS is the primary Windows Server technology associated with centralized management and deployment of approved Microsoft updates across an organization’s Windows environment.

Question 386. Which Windows Server technology provides a replicated namespace for files across multiple servers?

1. DFS Namespace and DFS Replication
2. DHCP and DNS
3. Storage Replica only
4. SMB Encryption only

Correct Answer: 1. DFS Namespace and DFS Replication

Explanation:

DFS Namespace and DFS Replication provide complementary capabilities for distributed file-server environments. DFS Namespace presents users with a logical path that can point to shared folders located on different servers. DFS Replication synchronizes files between configured replicated folder targets so that copies of the data can be maintained at multiple locations. Using both technologies can provide a consistent namespace while keeping selected file content synchronized across servers. Storage Replica provides block-level volume replication rather than a traditional DFS namespace, while DHCP and DNS provide network configuration and name resolution. SMB Encryption protects SMB traffic. Therefore, the combination of DFS Namespace and DFS Replication provides the required distributed file-access and replication capabilities.

Question 387. Which DFS Replication feature helps prevent a single large file from consuming excessive staging-folder resources during replication?

1. Quota Management
2. Staging quota
3. DNS Scavenging
4. DHCP Failover

Correct Answer: 2. Staging quota

Explanation:

DFS Replication uses staging folders to prepare files before transmitting them to replication partners. A staging quota helps control the amount of disk space that can be consumed by staged replication data. Proper staging configuration is important because insufficient staging space can affect replication efficiency and may cause additional staging operations. Administrators should size staging areas appropriately for the workloads and file sizes involved. FSRM Quota Management controls storage consumption at the file-server level but is not the DFSR-specific staging mechanism. DNS Scavenging removes stale DNS records, while DHCP Failover provides DHCP service redundancy. Therefore, the staging quota is the DFS Replication feature directly associated with controlling staging-folder storage consumption.

Question 388. Which SMB feature provides encryption for data transferred between SMB clients and servers?

1. SMB Compression
2. SMB Multichannel
3. SMB Encryption
4. SMB Direct

Correct Answer: 3. SMB Encryption

Explanation:

SMB Encryption protects the confidentiality of data transferred between SMB clients and servers by encrypting SMB traffic. It is useful when sensitive information is transmitted across networks where administrators want to reduce the possibility of unauthorized inspection. SMB Encryption is different from SMB Signing, which focuses primarily on message integrity and authentication. SMB Compression reduces the amount of data transferred when compression is beneficial, SMB Multichannel can use multiple network connections to improve performance and resiliency, and SMB Direct uses RDMA-capable networking for high-performance communication. Therefore, SMB Encryption is the appropriate SMB capability when the requirement is to protect the confidentiality of file-sharing traffic.

Question 389. Which SMB feature can use multiple network interfaces simultaneously for improved throughput and resiliency?

1. SMB Multichannel
2. SMB Encryption
3. SMB Signing
4. SMB Compression

Correct Answer: 1. SMB Multichannel

Explanation:

SMB Multichannel allows SMB clients and servers to establish multiple network connections for a single SMB session when suitable network adapters and configurations are available. This can improve throughput by using multiple paths and can also provide resiliency if one network connection becomes unavailable. SMB Multichannel is particularly useful in server environments with multiple network interfaces or technologies that provide multiple communication paths. SMB Encryption protects confidentiality, SMB Signing provides message integrity, and SMB Compression can reduce transmitted data size. Therefore, when the requirement is to use multiple network interfaces for improved SMB performance and connection resilience, SMB Multichannel is the appropriate feature.

Question 390. Which SMB feature allows SMB traffic to use RDMA-capable network adapters?

1. SMB Witness
2. SMB Direct
3. SMB Signing
4. SMB Encryption

Correct Answer: 2. SMB Direct

Explanation:

SMB Direct enables SMB communication over network adapters that support Remote Direct Memory Access, or RDMA. RDMA can provide high throughput and low latency while reducing CPU overhead associated with data movement. This makes SMB Direct useful for demanding workloads such as virtualization and high-performance file-server environments when supported network hardware is available. SMB Witness is associated with clustered SMB availability notifications, SMB Signing provides integrity protection, and SMB Encryption protects the confidentiality of SMB traffic. Therefore, SMB Direct is the SMB capability specifically associated with using RDMA-capable network adapters for high-performance communication.

Question 391. Which Windows Server role provides centralized DNS name-resolution services for an Active Directory domain?

1. DHCP Server
2. DNS Server
3. FSRM
4. Storage Replica

Correct Answer: 2. DNS Server

Explanation:

The DNS Server role provides name-resolution services that are fundamental to Active Directory environments. Active Directory uses DNS to locate domain controllers and directory services, and domain members rely on DNS to resolve hostnames and service-location records. A properly configured DNS infrastructure is therefore essential for authentication, domain controller discovery, and many directory operations. DHCP Server supplies network configuration such as IP addresses and gateway information, FSRM manages file-server storage policies, and Storage Replica handles storage replication. Therefore, when the requirement is to provide centralized DNS name-resolution services for an Active Directory domain, the DNS Server role is the appropriate Windows Server role.

Question 392. Which Active Directory service-location record helps clients locate Kerberos services?

1. MX
2. PTR
3. SRV
4. CNAME

Correct Answer: 3. SRV

Explanation:

SRV records identify the location of specific network services and are heavily used by Active Directory. Kerberos authentication is one of the services for which Active Directory relies on DNS service-location records. Domain controllers register appropriate SRV records so clients can locate domain services and select suitable servers. MX records identify mail exchange servers, PTR records provide reverse name resolution, and CNAME records provide hostname aliases. Correct SRV registration is therefore important for reliable Active Directory operation and domain-controller discovery. When an administrator needs to identify the DNS record type used to locate Kerberos services, SRV is the correct answer.

Question 393. Which Windows Server feature allows a server to be managed remotely without installing the full graphical shell?

1. Server Core
2. Disk Cleanup
3. File History
4. Storage Spaces

Correct Answer: 1. Server Core

Explanation:

Windows Server Core is a minimal installation option that does not include the traditional graphical desktop shell. Because of its reduced local interface and smaller installation footprint, administrators commonly manage Server Core remotely using tools such as Windows Admin Center, PowerShell, Server Manager, or other supported management utilities. Server Core can reduce the number of installed components that need to be maintained and is suitable for many server workloads. Disk Cleanup manages unnecessary files, File History is a client-oriented file-protection feature, and Storage Spaces provides software-defined storage. Therefore, Server Core is the installation option that is commonly managed remotely without the full graphical shell.

Question 394. Which PowerShell remoting protocol is commonly used by Windows Remote Management?

1. FTP
2. WinRM
3. SMB
4. SMTP

Correct Answer: 2. WinRM

Explanation:

Windows Remote Management, or WinRM, provides the underlying management framework commonly used by PowerShell remoting to communicate with remote Windows systems. PowerShell remoting can use WS-Management-based communication to execute commands and establish remote sessions. Administrators can configure appropriate listeners, authentication methods, firewall rules, and security settings to support remote management. FTP is primarily used for file transfers, SMB provides file and printer-sharing functionality, and SMTP is associated with email transmission. Therefore, WinRM is the appropriate Windows management technology associated with PowerShell remoting and remote command execution.

Question 395. Which PowerShell cmdlet opens an interactive session with a remote Windows computer?

1. Invoke-Command
2. Enter-PSSession
3. Get-ComputerInfo
4. Start-Service

Correct Answer: 2. Enter-PSSession

Explanation:

Enter-PSSession creates an interactive PowerShell session with a remote computer. After the session is established, commands entered by the administrator are executed in the context of the remote system, making it useful for interactive troubleshooting and administration. When the administrator exits the session, control returns to the local PowerShell environment. Invoke-Command is more commonly used to execute commands or scripts remotely, including against multiple computers, without necessarily opening an interactive session. Get-ComputerInfo retrieves system information, while Start-Service controls services. Therefore, Enter-PSSession is the appropriate cmdlet when an administrator needs an interactive remote PowerShell session.

Question 396. Which Azure service can discover dependencies between on-premises servers before migration planning?

1. Azure DNS
2. Azure Files
3. Azure Migrate
4. Azure Policy

Correct Answer: 3. Azure Migrate

Explanation:

Azure Migrate provides assessment and migration capabilities that can help organizations understand their on-premises server environment before moving workloads to Azure. Dependency analysis can help identify communication relationships between servers and workloads, which can be useful when planning migration groups and sequencing migration activities. Understanding these dependencies reduces the risk of moving a server without the supporting services or applications it relies on. Azure DNS provides DNS services, Azure Files provides managed file shares, and Azure Policy provides governance controls. Therefore, Azure Migrate is the appropriate Azure service when administrators need to assess server dependencies as part of a migration planning process.

Question 397. Which Azure service can collect performance metrics and trigger alerts when monitored conditions are met?

1. Azure Monitor
2. Azure Migrate
3. Azure Files
4. Azure DNS

Correct Answer: 1. Azure Monitor

Explanation:

Azure Monitor provides monitoring capabilities for metrics, logs, alerts, and other operational information across supported Azure and connected environments. Administrators can configure alert rules that evaluate metrics or other monitoring signals and generate notifications or actions when specified conditions are met. This can help organizations identify performance problems, availability issues, or other operational events. Azure Migrate focuses on migration assessment and planning, Azure Files provides managed file storage, and Azure DNS provides domain-name resolution. Therefore, when the requirement is to collect performance metrics and generate alerts based on defined conditions, Azure Monitor is the appropriate Azure service.

Question 398. Which Azure Arc capability allows an on-premises Windows Server to be represented and managed as an Azure resource?

1. Azure Files
2. Azure Arc-enabled servers
3. Azure DNS
4. Azure Backup Vault only

Correct Answer: 2. Azure Arc-enabled servers

Explanation:

Azure Arc-enabled servers extend Azure management capabilities to supported servers running outside Azure, including eligible on-premises and other connected environments. After a server is connected appropriately, it can be represented in Azure Resource Manager and can participate in supported management, governance, monitoring, and policy scenarios. This provides a centralized management model without requiring the physical server to run inside an Azure datacenter. Azure Files provides cloud-based file shares, Azure DNS provides DNS capabilities, and an Azure Backup vault is associated with backup management rather than the general Arc representation of a server. Therefore, Azure Arc-enabled servers provide the required capability.

Question 399. Which Windows Server recovery option restores the entire server after a catastrophic system failure?

1. Bare-metal recovery
2. File copy
3. DNS restore
4. DHCP restore

Correct Answer: 1. Bare-metal recovery

Explanation:

Bare-metal recovery is designed for situations where an entire Windows Server system needs to be restored after a catastrophic failure. It can restore the operating system and other backed-up system components required to rebuild the server environment. This is different from restoring individual files or specific application data because bare-metal recovery addresses the server as a complete system. System State backup is particularly important for recovering critical configuration information and Active Directory components on domain controllers, but a bare-metal recovery scenario has a broader restoration objective. Therefore, when the requirement is to recover an entire failed Windows Server installation, bare-metal recovery is the appropriate recovery method.

Question 400. Which Windows Server technology provides a centralized browser-based interface for managing failover clusters, virtual machines, storage, and networking?

1. Windows Admin Center
2. WSUS
3. FSRM
4. DNS Manager

Correct Answer: 1. Windows Admin Center

Explanation:

Windows Admin Center provides a browser-based management interface for administering Windows Server and supported infrastructure components. Administrators can use it to manage individual servers, failover clusters, Hyper-V virtual machines, storage, networking, certificates, firewall settings, services, and other system resources. It provides a centralized management experience that can reduce reliance on multiple traditional management consoles and can also integrate with supported Azure services. WSUS focuses on update management, FSRM manages file-server storage policies, and DNS Manager administers DNS infrastructure. Therefore, Windows Admin Center is the appropriate technology when a centralized browser-based interface is required for managing servers, clusters, virtual machines, storage, and networking.
