## Module: Azure Virtual Desktop Architecture & Design
1. **How would you design a highly available, multi-region Azure Virtual Desktop environment?**
Use Azure Virtual Desktop with host pools in multiple regions (e.g., East US and West Europe). Deploy Session Hosts in Availability Zones within each region. Use Azure Front Door or Traffic Manager for global load balancing and failover. Store user profiles with FSLogix on Azure Files Premium with geo-redundant replication (GRS). Implement Azure AD Join (Entra ID Join) for identity. Use Azure Autoscale for dynamic scaling. Enable Azure Site Recovery for disaster recovery of VMs and Azure Files. This ensures low latency, high availability, and compliance with data residency requirements.
2. **What are the key differences between personal and pooled host pools?**
Personal host pools assign a dedicated VM to each user (persistent desktop experience). Pooled host pools share VMs among multiple users (multi-session Windows 10/11 Enterprise). Personal is ideal for power users or line-of-business apps requiring persistence. Pooled is cost-effective for shift workers or knowledge workers. In 2025, pooled host pools support Windows 11 multi-session with Azure AD Join and Microsoft 365 Apps.
3. **How does Azure Virtual Desktop support Windows 11 multi-session?**
Windows 11 Enterprise multi-session is available in Azure Virtual Desktop. It allows multiple concurrent users on a single VM (up to 10–20 users depending on workload). Requires Azure AD Join (not Hybrid Azure AD Join) and Microsoft 365 E3/E5 licenses. Supports GPU VMs (NV-series) for graphics-intensive workloads.
4. **Explain the role of FSLogix in AVD and best practices for profile management.**
FSLogix provides user profile containers (VHDX files) that roam with users across sessions. Best practices: Store profiles on Azure Files Premium with SMB 3.0+ encryption, use Cloud Cache for high availability, enable profile container caching, set size quotas, and exclude large folders (e.g., Temp, Downloads). Use Azure Files AD DS authentication or Entra ID Kerberos for identity.
5. **How would you implement auto-scaling in Azure Virtual Desktop?**
Use Azure Virtual Desktop Autoscale (preview in 2025) or the older Azure Automation-based scaling script. Autoscale supports schedule-based and load-based scaling. Define host pool tags, set capacity thresholds, and integrate with Azure Monitor alerts. For pooled host pools, it can start/stop VMs and drain sessions gracefully. Best practice: Combine with Azure Reservations for cost savings.
## Module: Security & Identity
6. **How do you secure Azure Virtual Desktop with Microsoft Entra ID (Azure AD) and Conditional Access?**
Use Entra ID Join for Session Hosts. Implement Conditional Access policies requiring MFA, compliant devices, and location-based restrictions. Use Azure AD Application Proxy or Azure Front Door with WAF for external access. Enable Microsoft Defender for Cloud and Sentinel for threat detection. Use Azure RBAC for resource access and Just-In-Time (JIT) access with Privileged Identity Management (PIM).
7. **What is the difference between Azure AD Join and Hybrid Azure AD Join for AVD?**
Azure AD Join (Entra ID Join) is cloud-only and required for Windows 11 multi-session. Hybrid Azure AD Join syncs on-premises AD with Azure AD and supports traditional domain-joined VMs. Hybrid Join is still supported for Windows 10 multi-session and legacy apps but is being phased out for new deployments.
8. **How do you implement MFA for Azure Virtual Desktop access?**
Use Microsoft Entra ID Conditional Access policies to enforce MFA for AVD sign-in. For external users, integrate with Azure AD B2B or use Microsoft 365 E5 licenses with Azure AD Premium P1/P2. Enable MFA on the Windows client and web access.
9. **How would you secure remote access to AVD using Azure Front Door?**
Place Azure Front Door in front of AVD with WAF policies, DDoS protection, and SSL termination. Use private link for Session Hosts (no public IPs). Route traffic through Front Door to reduce latency and improve global performance.
## Module: Networking & Connectivity
10. **What is the recommended networking architecture for Azure Virtual Desktop?**
Deploy Session Hosts in a dedicated VNet with subnet delegation. Use Azure Private Link for AVD control plane. For on-premises connectivity, use Azure ExpressRoute or VPN Gateway. Implement Azure Firewall or Network Security Groups (NSGs) with Just-In-Time rules. Use Azure Route Server for dynamic routing if needed.
11. **How do you troubleshoot connectivity issues in AVD?**
Check Azure Virtual Desktop service health, verify NSG rules, use Azure Network Watcher for packet capture, and review Event Viewer logs on Session Hosts. Common issues: Port 443 blocked, DNS resolution, or Conditional Access policy failures. Use the AVD diagnostics tool in the Azure portal.
## Module: Monitoring, Management & Troubleshooting
12. **How do you monitor Azure Virtual Desktop performance and user experience?**
Use Azure Monitor for AVD with built-in metrics (CPU, memory, session count) and insights. Enable Azure Virtual Desktop insights workbook. Use Azure Log Analytics to query session host logs and user connection events. Integrate with Microsoft Sentinel for security monitoring.
13. **What is the Azure Virtual Desktop diagnostics tool and how do you use it?**
A centralized portal tool that collects logs from the control plane and Session Hosts. Enable diagnostics in the host pool settings, send logs to Log Analytics, and use the diagnostics workbook to troubleshoot connection failures, performance issues, and configuration problems.
14. **How do you perform a capacity assessment and right-size AVD VMs?**
Use Azure Virtual Desktop insights and Azure Advisor recommendations. Collect performance data with Azure Monitor. Common sizing: D4s_v5 (4 vCPU, 16 GB) for light workloads, NV-series for graphics. Use Azure Reservations and Spot VMs for cost savings.
## Module: Integration & Advanced Scenarios
15. **How do you integrate Azure Virtual Desktop with Microsoft Intune for device management?**
Enroll Session Hosts in Intune using Azure AD Join. Apply compliance policies, configuration profiles, and app protection policies. Use Intune to deploy Microsoft 365 Apps and manage updates.
16. **Explain how to use Azure Virtual Desktop with Microsoft Teams optimization.**
Enable Teams optimization on Windows 10/11 multi-session VMs. Use the latest Teams client and WebRTC redirector. This offloads media processing to the client device, improving audio/video quality and reducing latency.
17. **How would you migrate from Citrix/RDS to Azure Virtual Desktop?**
Assess current workload with Azure Migrate. Create new AVD host pools with similar sizing. Migrate user profiles using FSLogix containers. Use Azure AD Connect for identity sync. Perform phased migration with user acceptance testing.
18. **What is Azure Virtual Desktop App Attach and how does it work?**
App Attach (formerly MSIX app attach) allows dynamic delivery of MSIX packages to Session Hosts without installing apps. Packages are attached at user sign-in. Requires Windows 10/11 Enterprise multi-session and Azure Files for storage.
## Module: Cost Optimization & Licensing
19. **How do you optimize costs in an Azure Virtual Desktop deployment?**
Use Azure Reservations for VMs, Spot VMs for non-critical workloads, Azure Autoscale to stop unused VMs, Azure Files Premium with reserved capacity, and right-size VMs based on usage. Leverage Microsoft 365 E3/E5 licenses for multi-session.
20. **What licensing is required for Azure Virtual Desktop in 2025?**
Windows 10/11 Enterprise multi-session requires Microsoft 365 E3/E5, Windows E3/E5, or RDS CALs. Personal desktops require Windows 10/11 Enterprise licenses. Azure AD Premium P1/P2 is recommended for Conditional Access.
## Module: Scenario-Based & Advanced Questions
