Operational Procedures is 21% of the CompTIA A+ 220-1202 Core 2 exam. This module covers documentation, change management, backups, safety, environment, professionalism, scripting, remote access, and AI basics. This domain is about doing the job correctly and professionally, not just technically.
A great technician follows process. You document your work, manage change safely, back up before you break things, stay safe, and treat customers well. This module covers the professional habits that keep IT running and keep you employed.
Documentation Best Practices
You record everything so others can follow your work.
| Document | Purpose |
|---|---|
| Ticketing system | Tracks issues and resolutions |
| Asset management / CMDB | Inventories hardware and software |
| Standard Operating Procedures (SOPs) | Step-by-step process guides |
| Knowledge base | Reusable how-to articles |
| Network topology diagrams | Maps the network layout |
Change Management
You control change so it does not cause outages.
- Request the change with a documented form.
- Assess risk and the scope of impact.
- Test in a sandbox before production.
- Get approval from the change board.
- Plan a rollback in case the change fails.
- Implement during a maintenance window.
- Document the result.
A rollback plan is what saves you when a change goes wrong.
Backup and Recovery
You protect data with the right backup type and rule.
| Backup type | What it copies |
|---|---|
| Full | Everything, slowest |
| Incremental | Changes since the last backup |
| Differential | Changes since the last full |
| Synthetic full | A full rebuilt from prior backups |
The 3-2-1 rule keeps 3 copies of data on 2 media types with 1 copy offsite. Test restores regularly because an untested backup is not a backup.
Safety Procedures
You protect yourself and the equipment.
- ESD straps and mats prevent static damage to components.
- Electrical safety means unplugging before service and never opening a PSU or CRT.
- Proper lifting uses the legs, not the back.
- Fire safety uses a Class C extinguisher for electrical fires.
Environmental Controls
You handle materials and power responsibly.
- MSDS/SDS sheets describe safe handling and disposal of chemicals.
- Battery and toner disposal follows local regulations, never the trash.
- A UPS provides battery backup and clean power during outages.
- A surge suppressor protects against voltage spikes.
- Maintain proper temperature and humidity to prevent damage and static.
Policies, Privacy, and Professionalism
You follow legal and ethical rules.
- Chain of custody documents evidence handling for incidents.
- DRM and EULA govern software licensing and use.
- Regulated data like PII, PHI, and PCI requires special handling.
- Acceptable Use Policies (AUPs) define proper use of company systems.
You use professional communication: clear language, active listening, setting expectations, and respecting the customer. Never argue or talk down to a user, even when they are wrong.
Scripting and Remote Access
You automate tasks and support users remotely.
| Extension | Language | Use |
|---|---|---|
| .bat | Batch | Legacy Windows scripts |
| .ps1 | PowerShell | Windows automation |
| .vbs | VBScript | Older Windows automation |
| .sh | Shell | Linux/macOS automation |
| .py | Python | Cross-platform scripting |
| .js | JavaScript | Web and automation |
| Remote tool | Use |
|---|---|
| RDP | Full Windows remote desktop |
| VPN | Secure tunnel to a network |
| SSH | Secure command-line access |
| VNC | Cross-platform screen sharing |
| RMM | Remote monitoring and management |
AI Basics
The 220-1202 exam now includes basic AI concepts. You apply AI tools responsibly.
- Application integration brings AI into business workflows.
- AI policy covers appropriate use and plagiarism concerns.
- AI limitations include bias, hallucinations, and accuracy problems, so verify AI output.
- Private vs public AI differs in data security, data source, and privacy. Never paste sensitive company data into a public AI tool.
