WGU D317 IT Applications OA (pdf) | 2026/2027 | Objective
Assessment | IT Applications
1. An end user reports that their Windows workstation is displaying a blue
screen with an error message and restarting repeatedly. Which tool should a
technician use first to analyze the crash dump files?
A) Task Manager
B) Performance Monitor
C) Windows Memory Diagnostic
D) Windows Debugger (WinDbg)
Correct Answer: Windows Debugger (WinDbg)
Rationale: WinDbg is a powerful debugging tool used to analyze crash dump
files and identify the root cause of Blue Screen of Death (BSOD) errors. Task
Manager monitors running processes, Performance Monitor tracks system
performance, and Windows Memory Diagnostic tests RAM for errors.
2. Which Windows 10 feature allows an administrator to control how updates
are delivered, including deferring feature updates and quality updates?
A) Windows Update for Business
B) Windows Server Update Services (WSUS)
C) Windows Insider Program
D) System Center Configuration Manager (SCCM)
Correct Answer: Windows Update for Business
Rationale: Windows Update for Business (WUfB) provides administrators with
control over the deployment of updates by allowing them to defer feature
and quality updates, set maintenance windows, and manage update rings.
,WSUS is used for on-premises update management, and the Windows Insider
Program is for testing preview builds.
3. A company is deploying new Windows 10 workstations using a
standardized image. Which deployment method uses a bootable USB drive
containing the Windows Preinstallation Environment (WinPE) to install the
operating system from a network share?
A) PXE boot
B) System Preparation Tool (Sysprep)
C) Windows Deployment Services (WDS)
D) Microsoft Deployment Toolkit (MDT)
Correct Answer: Microsoft Deployment Toolkit (MDT)
Rationale: MDT is a unified collection of tools, processes, and guidance for
automating desktop and server deployments. It uses a bootable WinPE USB
drive to connect to a deployment share on the network. PXE boot is a
network boot method, Sysprep generalizes an image for deployment, and
WDS is a server role for network-based installation.
4. A technician is configuring a Windows workstation to join an Active
Directory domain. Which network setting must be configured correctly to
locate the domain controller?
A) The default gateway
B) The subnet mask
C) The DNS server
D) The IP address
Correct Answer: The DNS server
,Rationale: To join an Active Directory domain, the workstation must be able
to resolve the domain controller's name using DNS. The DNS server setting
must point to a DNS server that hosts the SRV records for the Active
Directory domain.
5. Which command-line tool is used to repair corrupted Windows system files
by scanning and restoring them from a cached copy?
A) DISM
B) CHKDSK
C) SFC /scannow
D) GPUpdate
Correct Answer: SFC /scannow
Rationale: The System File Checker (SFC) tool, used with the `/scannow`
parameter, scans all protected system files and replaces corrupted versions
with cached copies. DISM is used to repair the Windows image, CHKDSK
checks disk integrity, and GPUpdate refreshes Group Policy settings.
6. A user is unable to access the internet but can ping other devices on the
local network. The technician runs `ipconfig` and sees that the IP address
starts with 169.254. Which of the following is the most likely cause?
A) The DNS server is down
B) The DHCP server is unavailable
C) The default gateway is misconfigured
D) The subnet mask is incorrect
Correct Answer: The DHCP server is unavailable
, Rationale: An IP address in the 169.254.x.x range indicates that the
computer has assigned itself an Automatic Private IP Addressing (APIPA)
address because it could not reach a DHCP server. This is a common issue
when the DHCP server is unavailable or the network cable is disconnected.
7. A technician needs to install a 64-bit application on a Windows 10
computer. Which of the following is a requirement for running 64-bit
applications?
A) The computer must have at least 4 GB of RAM
B) The processor must support 64-bit instructions
C) The computer must be running Windows 10 Home edition
D) The hard drive must be formatted with FAT32
Correct Answer: The processor must support 64-bit instructions
Rationale: A 64-bit application requires a processor that supports 64-bit
instructions and a 64-bit operating system. While 4 GB of RAM is often
recommended, it is not a strict requirement. Windows 10 Home does support
64-bit, but the processor must be 64-bit capable.
8. Which Windows utility allows an administrator to create and manage
virtual hard disks (VHDs) without using third-party software?
A) Disk Management
B) Diskpart
C) Hyper-V Manager
D) Both A and B
Correct Answer: Both A and B
