D317 IT Applications is the Western Governors University course on the software side of IT support: operating systems, security, troubleshooting and the procedures that keep support work safe and documented.
WGU's program guides list it at four competency units in degrees such as Information Technology, Cloud Computing and Cybersecurity, and say it prepares learners for the CompTIA A+ Core 2 exam. It partners with IT Foundations (D316), which covers Core 1.
Students find the operational procedures surprisingly tricky. Change management, documentation and safe malware removal follow set orders that exam questions test closely.

Key Concepts Explained
Malware Removal in Order
CompTIA's best-practice sequence is: investigate and verify symptoms, quarantine the system, disable System Restore (Windows), remediate (update tools, scan and remove), schedule scans and updates, re-enable System Restore and create a restore point, then educate the user.
Example: A laptop shows pop-ups and a redirected browser homepage. The technician confirms the symptoms, disconnects it from the network, disables System Restore so infected restore points are not reused, updates the anti-malware tool, scans and cleans, schedules regular scans, creates a fresh restore point and shows the user how the infection likely arrived.
Change Management
Changes to production systems go through a request, a documented plan with scope and risk, a rollback plan, approval (often by a change board), implementation and user acceptance. It prevents well-meant fixes from causing outages.
Backup Types
Full backups copy everything; incremental backups copy changes since the last backup of any kind; differential backups copy changes since the last full backup. Restores from incrementals need the full plus every incremental since.
How the Course Is Assessed
WGU states the course prepares learners for A+ Core 2. Confirm the assessment method for your program version on your course page, and use CompTIA's current objectives to track your coverage.
| Preparation activity | What it builds | How to use it |
|---|---|---|
| OS tool practice | Command and utility recall | Try each Windows tool and command in a VM |
| Procedure drills | Correct ordering | Write malware and change steps from memory |
| Practice questions | Scenario reasoning | Note which step or tool each question targets |
| Security comparisons | Choosing controls | Tables for authentication methods and Wi-Fi security |
Operating Systems at a Glance
The first competency asks you to identify operating systems and their configurations. A comparison table keeps the main differences straight:
| OS family | Where you meet it | Things to know |
|---|---|---|
| Windows | Most business desktops | Editions, Settings and Control Panel, command-line tools, user accounts |
| macOS | Creative and executive users | System Settings, Time Machine, Terminal basics |
| Linux | Servers and technical users | File system layout, permissions, package managers, common commands |
| Mobile | Phones and tablets | App sources, device management, security settings |
Questions often describe a user's environment and ask which tool or setting applies, so know where each task lives in each system.
Where Students Get Stuck
- Windows utilities. Many questions ask which tool fixes a problem; practice in a virtual machine.
- Command-line syntax. Know what common commands do rather than memorizing every switch.
- Procedure order. Malware removal and change management steps are tested in sequence.
- Linux and macOS basics. Students who only use Windows often neglect these sections.
Study Tips for D317
- Set up free virtual machines to explore Windows and Linux safely.
- Keep a one-page sheet of procedures (troubleshooting, malware removal, change management).
- Study by CompTIA domain and track weak areas in a simple table.
- Write a simple script in each common language listed in the objectives to see how they differ.

Frequently Asked Questions
WGU's program guides say IT Applications prepares learners for the CompTIA A+ Core 2 exam.
The program guides list it at four competency units.
Yes, the competencies include identifying scripting basics, alongside remote access technology.
Incremental backups copy changes since the last backup; differential backups copy changes since the last full backup.
It depends on your background. Hardware-minded learners often find D317's procedures and OS tools harder, and vice versa.
No. We offer tutoring and study notes only; exams must be taken by you.
