WGU D317: IT Applications
D317 is the second half of the CompTIA A+ pair: the course assessment is the A+ Core 2 (220-1102) exam, covering operating systems, security, software troubleshooting, and operational procedures. Passing it after D316 completes the full A+ certification.

What makes it hard
Core 2's Windows detail is the grind: control panel paths, command-line tools, and edition differences get tested specifically. Students who passed Core 1 on hardware intuition find Core 2 more memorization-bound, and the security and procedure questions punish vague familiarity.
What you'll cover
- • Windows administration and command-line tools
- • macOS, Linux, and mobile OS basics
- • Security concepts and malware removal
- • Software troubleshooting
- • Operational procedures and documentation
The D317 study guide
How to study for WGU D317, step by step.
- 1
Calibrate with a practice exam first
Core 2 is an external CompTIA exam with its own emphasis. A practice run shows whether your gaps are Windows tools, security, or procedures before you spend weeks in the wrong domain.
- 2
Learn the Windows tools hands-on
Open every utility the objectives name (Task Manager, Disk Management, the command-line tools) and use each once. Doing beats memorizing screenshots for the OS questions.
- 3
Drill the malware-removal and troubleshooting sequences
Core 2 tests its procedures as ordered steps. Learn the malware-removal sequence and best-practice methodology in order, because the exam asks what comes next.
- 4
Flashcard the security and procedure vocabulary
Authentication types, social-engineering attacks, and documentation practices are direct-recall territory. Short daily passes keep them current alongside the OS material.
- 5
Pass the practice gate, then book the cert
Hit WGU's required practice-assessment score with margin, then schedule the Core 2 exam promptly, since finishing it completes your full A+.

FAQ
Is WGU D317 hard?
It's considered slightly harder than D316 for most students because Core 2's Windows and procedure detail is memorization-bound. Hands-on practice with the actual tools is the reliable shortcut.
Do I need D316 before D317?
That's the standard order: D316 covers A+ Core 1 and D317 covers Core 2, and you need both exams for the full CompTIA A+ certification.
How long does D317 take?
Typically 4-8 weeks. Students fresh off D316 keep momentum; the new load is mostly operating systems and security procedures.
More WGU courses
C182: Introduction to IT
C182 is the foundational survey course for WGU's IT degrees, covering computing history, hardware, software, networking basics, and the role of IT in organizations. It's usually one of the first courses new IT students hit, and it ends in an objective assessment (OA).
C172: Network and Security Foundations
C172 covers networking models, common protocols, network devices, and baseline security concepts, essentially a lighter cousin of Network+ material. It's a core early course across WGU's IT and cybersecurity programs and ends in an OA.
C779: Web Development Foundations
C779 introduces HTML, CSS, and the basics of how websites are structured, styled, and published. It sits early in several WGU IT degree plans and is assessed with a proctored exam rather than a build-a-site project.
D426: Data Management - Foundations
D426 covers relational database fundamentals: the relational model, ER diagrams, normalization, and introductory SQL concepts, delivered through zyBooks. It ends in an OA and is the prerequisite for the hands-on D427.
