Advanced Azure Virtual Desktop (AVD) Interview Questions 2026

Azure Virtual Desktop (AVD), formerly Windows Virtual Desktop, continues to evolve as Microsoft’s premier cloud VDI solution. In 2026, key advancements include RDP Shortpath (UDP) over Private Link generally available for lower-latency connections, centralized RDP Shortpath management, RDP Multipath full rollout for improved bandwidth utilization, ephemeral OS disk support (public preview), enhanced multimedia redirection, FSLogix 2201 GA with better profile performance, hybrid deployment options via Azure Arc-enabled servers for on-premises session hosts, mandatory shift to Windows App (legacy MSRDC retirement March 2026), automatic Extended Security Updates (ESU) for Windows 10 in AVD, and tighter integrations with Microsoft Entra ID, Intune, and Azure Monitor.

This guide delivers advanced Azure Virtual Desktop interview questions and answers for 2026, emphasizing scenario-based, architecture, troubleshooting, security, and emerging hybrid/multi-region features. Tailored for senior roles like AVD Architect, Cloud Engineer, or Endpoint Specialist. Optimize your prep for enterprise deployments.

1. Explain the Core Architecture of Azure Virtual Desktop in 2026, Including Control Plane vs. Data Plane

Question Context: Tests deep understanding of AVD’s distributed, cloud-native design.

Answer: AVD’s architecture separates the control plane (managed by Microsoft in Azure) from the data plane (customer-managed in your subscription). The control plane includes:

• Broker service (session host assignment, load balancing)
• Gateway (RDP/UDP traffic routing)
• Diagnostics/REST APIs
• Workspace & application group management

The data plane comprises:

• Session hosts (VMs in host pools, running Windows 10/11 multi-session or Server)
• FSLogix profile containers
• Azure Files/ NetApp for profiles
• Networking (Virtual Network, NSGs, Private Link)

In 2026, enhancements include RDP Shortpath UDP over Private Link (GA) for direct, low-latency UDP traffic bypassing public gateways, and RDP Multipath for aggregating multiple connections. Hybrid extends to on-premises via Azure Arc. Emphasize scalability: auto-scaling, multi-region with Azure Traffic Manager, and Entra ID Join for modern auth.

2. What Are the Key Differences Between Personal and Pooled Host Pools, and When to Use Each in 2026 Scenarios?

Question Context: Assesses workload optimization knowledge.

Answer:

• Personal (dedicated): One-to-one user-to-VM assignment. Persistent desktops with user data preserved across sessions. Ideal for power users, developers, or apps requiring state (e.g., CAD software).
• Pooled: Multi-session shared VMs. Cost-effective for shift-based or knowledge workers. Supports Windows 11 Enterprise multi-session + Entra ID Join.

In 2026: Pooled benefits from ephemeral OS disks (preview) for faster scaling/reset, and multiple desktop assignment per user (GA). Use personal for high-performance GPU workloads (e.g., NVv4 series with HEVC support); pooled for general office/M365 with autoscale. Hybrid pooled now possible with Arc-enabled on-prem hosts.

3. How Do You Design a Multi-Region, Highly Available AVD Deployment?

Question Context: Scenario-based; probes DR and global resiliency.

Answer:

1. Deploy host pools per region (e.g., East US + West Europe).
2. Use Azure Traffic Manager or Front Door for global load balancing of workspaces.
3. Replicate FSLogix profiles via Azure Files Premium with geo-redundancy (GRS) or Cloud Cache.
4. Implement Azure Site Recovery for session host replication or scripted failover.
5. Enable RDP Shortpath over Private Link for cross-region low-latency.
6. Use autoscale with scaling plans and Azure Monitor alerts.

2026 Tip: Leverage regional host pool placement (preview) for metadata pinning and data sovereignty. For true DR, combine with Azure Backup for VMs and test failover regularly.

4. Explain FSLogix in AVD: Profile Management Best Practices and 2026 Updates

Question Context: Profiles are critical for user experience.

Answer: FSLogix creates virtual hard disks (VHDX) for user profiles/roaming, stored on Azure Files, NetApp, or Storage Spaces Direct. Key features: Cloud Cache for resiliency, Office Container for M365 optimization.

Best practices:

• Use Premium SSD/Files for low latency.
• Enable Cloud Cache with multiple providers.
• Set concurrent sessions limits.
• Monitor with Azure Monitor/Insights.

In 2026: FSLogix 2201 GA brings faster sign-in/out, improved cloud cache performance, accessibility fixes. Integrate with ephemeral disks for pooled hosts to reduce profile bloat.

5. How Do You Secure AVD Deployments in 2026? Cover MFA, Conditional Access, and Network Security

Question Context: Security is paramount post-2026 updates.

Answer:

• Enforce Entra ID MFA + Conditional Access (device compliance via Intune).
• Use Private Link for gateway traffic, disable public access.
• Implement RDP Shortpath UDP over Private Link (GA 2026) for secure, direct routing.
• Apply NSGs, Azure Firewall, Bastion for admin access.
• Enable Just-In-Time (JIT) VM access.
• Monitor with Microsoft Defender for Cloud + Sentinel.

2026: Prepare for MSRDC retirement (March 2026) — migrate to Windows App with modern auth. Use Azure AD Kerberos for hybrid auth.

6. Describe AVD Autoscale and Scaling Plans: Implementation and Troubleshooting

Question Context: Cost optimization in dynamic environments.

Answer: Autoscale uses scaling plans (depth-first/ramp-up) to power on/off hosts based on schedules, capacity thresholds, or load. Integrate with Azure Automation or Logic Apps.

Troubleshooting:

• Check Azure Monitor logs for scaling events.
• Verify host pool tags and RBAC.
• Ensure Entra ID app registration permissions.

2026: Enhanced with RDP Multipath for better session distribution during scale-out.

7. What Are Hybrid Deployment Options for AVD in 2026?

Question Context: Emerging hybrid focus.

Answer: New in late 2025/2026: Azure Virtual Desktop for hybrid environments (preview/GA) uses Azure Arc-enabled servers as session hosts on-premises or other clouds. Manage via Azure portal with consistent broker/gateway. Benefits: Extend cloud management to legacy data centers, unified identity via Entra ID hybrid join.

Use cases: Gradual migration, regulatory data residency, or Nutanix/Azure Stack integration.

8. How Do You Troubleshoot Common AVD Connectivity Issues in 2026?

Question Context: Hands-on diagnostics.

Answer:

1. Use AVD Insights (Azure Monitor) for connection diagnostics.
2. Check RDP Shortpath status (UDP via Private Link).
3. Verify gateway health, firewall rules (ports 443, UDP 3390+).
4. Review session host agent version (latest 1.0.13514+ validation).
5. For auth failures: Apply patches like KB5077793 (Jan 2026 fix).
6. Use Windows App diagnostics post-MSRDC retirement.

9. Explain GPU Acceleration and Multimedia Redirection in AVD

Question Context: Media/performance workloads.

Answer: GPU VMs (NV-series) enable hardware acceleration. Multimedia redirection (enhanced preview 2025+) offloads browser/media to client device for better perf (e.g., WebRTC, HEVC/H.265 GA).

2026: Use with Windows 11 multi-session for Teams/Zoom optimization.

10. How Does Licensing Work for AVD in 2026, Including ESU and Windows 11?

Question Context: Cost/compliance.

Answer: Requires qualifying license (M365 E3/E5, Windows E3/E5 + RDS CALs, or standalone AVD access). Windows 10 gets automatic ESU in AVD until 2028 (no extra cost). Windows 11 multi-session needs Entra ID Join.

Migrate images without M365 Apps for extended support.
