You are deploying an application that uses Windows Authentication. Remote users connect through a reverse proxy. Which IIS authentication configuration allows the proxy to pass the authenticated user identity to the backend?

Answer: Configure Constrained Delegation (S4U2Proxy) on the proxy server account

Constrained Delegation with S4U2Proxy allows the proxy server's computer account to impersonate authenticated users when forwarding requests to the backend IIS server.

A line-of-business application stores data in a SQL Server database. You need to configure the IIS application pool to connect to SQL Server using Windows Authentication without storing credentials. Which identity should the application pool use?

Answer: A domain service account with db_datareader/writer permissions on SQL Server

A domain service account can be granted specific SQL Server permissions, allowing Windows Integrated Authentication from IIS to SQL Server without embedded credentials.

Your organization is deploying a new internal application using HTTPS. The PKI team provides a certificate. After binding the certificate in IIS, HTTPS requests fail with SSL_ERROR_RX_RECORD_TOO_LONG. What is the most likely cause?

Answer: The HTTPS binding is on the wrong port or HTTP traffic is hitting the HTTPS port

SSL_ERROR_RX_RECORD_TOO_LONG typically means a plain HTTP request reached a port expecting SSL/TLS, indicating a misconfigured port binding or client URL.

A Windows Server 2012 R2 application uses MSMQ for asynchronous messaging. After a server reboot, messages are lost. Which MSMQ queue type should be used to prevent this?

Answer: Transactional queue with recoverable (persistent) messages

Transactional queues with recoverable messages write message data to disk, ensuring messages survive server reboots or crashes.

You need to monitor an IIS web application for performance issues. Which Windows Server tool provides real-time performance counters for ASP.NET requests per second and request queue length?

Answer: Performance Monitor (PerfMon) with ASP.NET and Web Service counter sets

Performance Monitor provides detailed ASP.NET and IIS Web Service counter sets including requests/sec, queue length, and errors that Task Manager does not expose.

An organization wants to use Windows Server 2012 R2 to deliver virtual desktops to thin clients. Which RDS deployment model streams a full desktop from a shared OS session to multiple users?

Answer: Session-based desktop deployment using RD Session Host

Session-based desktops use RD Session Host, where multiple users share a single OS instance with isolated sessions, making it more resource-efficient than per-user VMs.

A company is migrating an application to Windows Server 2012 R2 and needs to ensure the application can write to a legacy registry key under HKLM. The application runs as a standard user. Which technology provides virtualization of registry writes for compatibility?

Answer: UAC virtualization redirects HKLM writes to the user's HKCU hive for non-elevated processes

UAC file and registry virtualization silently redirects HKLM writes from non-elevated legacy applications to a per-user virtualized store, maintaining compatibility without privilege escalation.
