The 220-1102 exam is structured around four major domains, each testing a different set of skills and knowledge areas:
In-Depth Domain Breakdown
- Operating Systems (31%)
This domain is the most significant section of the exam. It focuses on installing, configuring, and managing various operating systems, with a primary emphasis on Windows (including Windows 10 and 11). Key areas include:
- Installation and Upgrades: Installing Windows from scratch, upgrading existing systems, and understanding the differences between Windows editions (Home, Pro, Enterprise, etc.).
- Configuration: Setting up user accounts, configuring system settings, and managing system updates.
- Command-Line Tools: Familiarity with tools for troubleshooting and system management, such as ipconfig, chkdsk, sfc, gpupdate, netstat, ns lookup, and others.
- Other OS Knowledge: Basic navigation and troubleshooting for macOS, Linux (file permissions, package management), Chrome OS, and Android. Understanding their unique security and operational features is increasingly vital as organizations diversify their device environments.
Example Scenario:
A user reports that their Windows 10 laptop is running slowly. To resolve the issue, you might use Task Manager to identify resource-heavy processes, run chkdsk to check for disk errors, and update system drivers.
- Security (25%)
Security is a critical focus of the 220-1102 exam. Candidates are expected to understand and implement both physical and logical security measures:
- Physical Security: Use of locks, badge readers, surveillance cameras, and secure disposal of sensitive data.
- Logical Security: User account management, password policies, multi-factor authentication, and permissions (NTFS vs. share permissions).
- Antivirus and Firewalls: Configuring Windows Defender Antivirus, enabling and configuring firewalls, and understanding malware types and removal methods.
- Encryption: Implementing BitLocker and BitLocker To Go for drive encryption, using EFS for file encryption.
- Mobile Device Security: Applying screen locks, remote wipes, device encryption, and managing BYOD (Bring Your Device) policies.
- Network Security: Securing routers (changing default passwords, updating firmware), configuring wireless security (WPA2, WPA3), and managing firewall ports.
- Browser Security: Managing extensions, using password managers, enabling pop-up blockers, and practicing safe browsing habits.
Example Scenario:
You’re tasked with securing a small office network. You would ensure all routers use unique admin passwords, enable WPA3 wireless encryption, and set up Windows Defender on all workstations.

- Software Troubleshooting (22%)
This domain tests your ability to diagnose and resolve standard software and security issues:
- Operating System Issues: Troubleshooting boot failures, slow performance, system instability, and “No OS found” errors.
- Application Issues: Resolving crashes, failed installations, and compatibility problems.
- Malware and Security Issues: Identifying and removing malware, recognizing false antivirus alerts, and restoring altered system files.
- Troubleshooting Tools: Using Windows Recovery Environment, System File Checker (sfc), System Restore, and reimaging systems.
- Methodologies: Following a structured troubleshooting approach to the problem, establish a theory, test solutions, implement fixes and document findings.
Example Scenario:
If a user’s PC is infected with ransomware, you would disconnect it from the network, boot into Safe Mode, run antivirus scans, and, if necessary, restore from a clean backup.
- Operational Procedures (22%)
Operational procedures encompass best practices for IT support, documentation, safety, and professionalism:
- Documentation: Utilizing ticketing systems, writing clear incident reports, and maintaining accurate records.
- Change Management: Understanding and following system changes, updates, and rollback procedures.
- Disaster Recovery: Developing and implementing backup strategies, restoring data, and planning for business continuity.
- Safety and Environmental Procedures: Adhering to ESD (electrostatic discharge) precautions, proper equipment handling, and environmental disposal of hardware.
- Professionalism: Communicating effectively with users, respecting privacy, and following company policies.
- Scripting Basics: Understanding simple scripts for automation and troubleshooting.
- Remote Access: Configuring and using remote support tools to assist users offsite.
Example Scenario:
If a server experiences a critical failure, you would follow the disaster recovery plan, restore data from backups, and document the incident for future reference.
