70-413 Exam Technology & Digital Applications 2 — Questions and Answers
Question 1: A company needs to deploy a Windows Server 2012 R2 application that requires a specific version of .NET Framework not available by default. Which feature should you install first?
- .NET Framework 3.5 via Server Manager (Correct answer)
- Application Server role
- Web Server (IIS) role
- Windows Process Activation Service
Correct answer: .NET Framework 3.5 via Server Manager
.NET Framework 3.5 can be added as a feature through Server Manager or DISM, providing legacy runtime support for older applications.
Question 2: You are designing a highly available web application tier on Windows Server 2012 R2. Which technology provides session persistence (sticky sessions) at the network load balancing level?
- Network Load Balancing with port rules set to single affinity (Correct answer)
- DNS round-robin with TTL of 0
- Failover Clustering with shared storage
- Windows Azure Traffic Manager
Correct answer: Network Load Balancing with port rules set to single affinity
NLB port rules configured with single (client IP) affinity ensure requests from the same client are always directed to the same node.
Question 3: An administrator needs to automate application deployment across 50 servers using a push model. Which Windows Server 2012 R2 feature best supports this scenario?
- Windows PowerShell Desired State Configuration (DSC) (Correct answer)
- Windows Deployment Services (WDS)
- Microsoft Deployment Toolkit (MDT)
- Remote Desktop Services RemoteApp
Correct answer: Windows PowerShell Desired State Configuration (DSC)
PowerShell DSC uses a push or pull model to enforce consistent application and configuration state across many servers.
Question 4: Your organization runs a line-of-business application that requires legacy 32-bit COM components on a 64-bit server. What IIS application pool setting must you enable?
- Enable 32-Bit Applications set to True (Correct answer)
- Managed Pipeline Mode set to Classic
- Identity set to LocalSystem
- Idle Time-out set to 0
Correct answer: Enable 32-Bit Applications set to True
Setting 'Enable 32-Bit Applications' to True in the application pool allows IIS to host 32-bit worker processes on a 64-bit OS.
Question 5: A developer reports that an IIS-hosted application periodically recycles and loses in-memory session state. Which solution preserves session state across application pool recycles?
- Configure ASP.NET session state to use SQL Server (Correct answer)
- Increase the application pool idle timeout to 0
- Enable HTTP keep-alive in IIS
- Set the recycling schedule to never
Correct answer: Configure ASP.NET session state to use SQL Server
Storing ASP.NET session state in SQL Server externalizes it from the worker process, so recycles do not cause session loss.
Question 6: You need to publish an internal web application so remote users can access it without a VPN. Which Windows Server role provides this capability with pre-authentication?
- Web Application Proxy (WAP) (Correct answer)
- Routing and Remote Access Service (RRAS)
- Network Policy Server (NPS)
- DirectAccess
Correct answer: Web Application Proxy (WAP)
Web Application Proxy publishes internal applications externally and supports AD FS pre-authentication to verify identity before forwarding requests.
Question 7: An organization wants to virtualize a legacy application server but the application vendor only supports physical hardware. Which Hyper-V feature minimizes risk by capturing the physical server state?
- Hyper-V Virtual Machine with P2V migration using disk2vhd (Correct answer)
- Hyper-V Replica
- Live Migration
- Integration Services update
Correct answer: Hyper-V Virtual Machine with P2V migration using disk2vhd
disk2vhd converts a physical server's disk to a VHD/VHDX file that can be booted in Hyper-V, enabling P2V migration without downtime tools.
