The CompTIA A+ 220-1102 Core 2 exam is the second of two required tests that together earn candidates the full CompTIA A+ certification. While the 220-1101 Core 1 exam focuses on hardware and networking fundamentals, Core 2 concentrates on operating systems, security, software troubleshooting, and operational procedures. This exam is designed to validate the skills needed for entry-level IT support roles across a wide range of industries and organizational environments.
The exam consists of a maximum of 90 questions, including multiple-choice and performance-based questions, with a 90-minute time limit. A passing score of 700 on a scale of 100 to 900 is required. The exam fee is approximately $246 USD, though pricing varies by region and testing provider. Earning the A+ certification demonstrates to employers that a candidate possesses the practical skills needed to support end users, manage operating systems, and apply foundational security practices in real workplace environments.
Official Exam Domain Breakdown
The 220-1102 exam is organized into four primary domains that each carry a specific weight in the final score. Operating Systems is the largest domain at 31 percent and covers Windows, macOS, Linux, and mobile operating systems. Security follows at 25 percent and addresses threats, vulnerabilities, and protective measures. Software Troubleshooting accounts for 22 percent and focuses on resolving common application and operating system issues. Operational Procedures rounds out the exam at 22 percent and includes documentation, change management, and professional communication.
Knowing the domain weights helps you allocate study time effectively rather than spreading effort equally across all topics. The Operating Systems domain demands the most attention due to its broad scope and high percentage of exam questions. Security and Software Troubleshooting are nearly equal in weight and together represent nearly half of the exam content. Reviewing the official CompTIA exam objectives document for SY0-1102 before starting your preparation gives you a precise checklist of every topic the exam may test on any given attempt.
Windows Operating System Essentials
Windows is the dominant operating system tested in the Core 2 exam, and candidates must develop strong familiarity with multiple versions including Windows 10 and Windows 11. You should know the differences between Home, Pro, and Enterprise editions and understand which features are exclusive to higher-tier versions such as BitLocker, Group Policy, and domain join capability. Edition selection often appears in scenario-based questions where you must recommend the correct version for a described business requirement.
Windows command-line tools are frequently tested and include commands such as ipconfig, ping, tracert, netstat, sfc, chkdsk, diskpart, and gpupdate. Candidates must know what each command does, what output it produces, and when to use it during troubleshooting. The Windows Registry, Task Manager, Event Viewer, Device Manager, and Control Panel are all important administrative tools that appear in exam questions. Knowing how to access these tools through multiple methods, including Run commands and keyboard shortcuts, reflects the practical knowledge that A+ technicians apply daily.
macOS and Linux Fundamentals
Although Windows dominates the Core 2 exam, macOS and Linux each receive meaningful coverage that candidates should not overlook during preparation. For macOS, you should be familiar with tools such as Finder, Spotlight, Time Machine, Disk Utility, and the System Preferences panel. Common macOS features like FileVault encryption, iCloud integration, and the built-in Keychain password manager are tested at a conceptual level appropriate for a support technician role.
Linux knowledge required for the exam focuses primarily on the command line and common distributions used in enterprise and development environments. Commands such as ls, cd, pwd, chmod, chown, grep, ps, and sudo are regularly tested. Understanding file permissions using numeric and symbolic notation is essential for answering Linux-related scenario questions. Candidates should also know the purpose of key Linux directories such as /etc, /var, /home, and /usr. While deep Linux administration knowledge is not required, a working familiarity with the terminal and file system structure is necessary to pass Core 2 successfully.
Mobile Operating System Knowledge
Mobile operating systems, specifically Android and iOS, are covered in the Core 2 exam with a focus on support and troubleshooting rather than development. Candidates should understand the differences between the two platforms in terms of app installation sources, update mechanisms, and security models. Android allows sideloading applications from third-party sources, while iOS restricts installations to the Apple App Store by default, which has direct implications for enterprise security management.
Mobile device management, or MDM, is a critical concept for managing corporate mobile devices and appears frequently in exam questions. Candidates should know how MDM solutions enforce policies such as screen lock requirements, remote wipe capability, and application restrictions on both Android and iOS devices. Common mobile troubleshooting scenarios include battery drain issues, connectivity problems, failed app installations, and synchronization errors. Understanding how to perform factory resets, configure email accounts, and enable encryption on mobile devices prepares candidates for the practical support scenarios tested in this domain.
Security Threats and Attack Types
The Security domain in Core 2 covers a wide range of threats that IT technicians encounter in support roles. Candidates must be able to identify and differentiate between malware types including viruses, worms, trojans, ransomware, spyware, adware, and rootkits. Each malware type has distinct characteristics, propagation methods, and symptoms that help technicians identify infections and select appropriate remediation steps during real support incidents.
Social engineering attacks are also heavily tested and include phishing, spear phishing, vishing, smishing, tailgating, and shoulder surfing. Understanding how attackers manipulate human behavior rather than exploiting technical vulnerabilities is essential for the security portion of the exam. Candidates should know how to recognize signs of a phishing attempt in an email, identify physical security breaches like tailgating, and educate end users about safe behavior. Scenario questions often describe an attack situation and ask candidates to identify the attack type or recommend the most appropriate defensive response for the described environment.
Applying Security Best Practices
Beyond identifying threats, Core 2 candidates must understand how to implement security controls that protect systems and users in a support environment. Strong password policies, account lockout settings, and multi-factor authentication are foundational controls that appear in both conceptual and scenario-based questions. Candidates should know how to configure these settings in Windows through Local Security Policy and Group Policy tools.
Data encryption is another key security topic that includes BitLocker for full-disk encryption on Windows and FileVault on macOS. Candidates should understand the difference between encrypting individual files, folders, and entire drives and know which tools apply to each scenario. Patch management, automatic updates, and the importance of keeping software current to reduce vulnerability exposure are also tested. Physical security controls such as cable locks, smart card authentication, biometric readers, and privacy screens protect hardware and sensitive information in shared or public environments.
Malware Removal Step Process
The CompTIA A+ exam includes a specific six-step malware removal process that candidates must memorize and understand thoroughly. The steps are: identify and research malware symptoms, quarantine the infected system, disable System Restore in Windows, remediate the system using appropriate tools, schedule scans and run updates, and enable System Restore and create a restore point. Each step has a specific purpose and must be performed in the correct sequence to ensure effective and complete malware removal.
Quarantining the infected system before attempting removal is critical because active malware can spread across a network or interfere with removal tools if the system remains connected. Safe Mode is frequently used during the remediation step because many malware programs cannot run in Safe Mode, making them easier to detect and remove. After removal, re-enabling System Restore and creating a clean restore point ensures that the system cannot revert to an infected state through an older restore point. Candidates who memorize and apply this process will be well prepared for malware-related scenario questions on the exam.
Software Troubleshooting Methodology
Effective software troubleshooting requires a systematic methodology that the Core 2 exam tests extensively. The CompTIA troubleshooting methodology consists of seven steps: identify the problem, establish a theory of probable cause, test the theory, establish a plan of action, implement the solution, verify full functionality, and document findings. Applying this process consistently leads to faster resolution and better outcomes than attempting random fixes without a structured approach.
Common software issues tested in this domain include application crashes, slow performance, boot failures, and update errors. Candidates should know how to use Windows tools such as Event Viewer, Reliability Monitor, and Task Manager to diagnose performance and stability problems. Application compatibility issues between older software and newer operating systems are frequently presented in scenario questions. Solutions such as running programs in compatibility mode, updating drivers, or reinstalling applications with appropriate permissions are common remediation steps that candidates must be able to recommend based on the described scenario.
Operational Procedures and Documentation
Operational procedures represent a significant portion of the Core 2 exam and cover professional behaviors, documentation practices, and workplace policies. Change management is a formal process that organizations use to control modifications to IT systems and reduce the risk of unintended disruptions. Candidates should understand the components of a change management request including documentation, approval processes, rollback plans, and post-change testing procedures.
Documentation types tested in Core 2 include network diagrams, knowledge base articles, acceptable use policies, standard operating procedures, and incident reports. Keeping accurate and up-to-date documentation supports consistent service delivery and helps technicians resolve recurring issues more efficiently. Acceptable use policies define how employees may use organizational technology resources and what behaviors are prohibited. Candidates should know the purpose of each documentation type and be able to identify which type is most appropriate for a described organizational scenario or compliance requirement.
Backup and Recovery Strategies
Data backup and recovery is a critical operational topic in the Core 2 exam that applies to both individual users and enterprise environments. Candidates must understand the three primary backup types: full, incremental, and differential. A full backup copies all selected data regardless of whether it has changed since the last backup. An incremental backup copies only data changed since the last backup of any type, while a differential backup copies all data changed since the last full backup.
The 3-2-1 backup rule is a widely recommended best practice that states organizations should maintain three copies of data, stored on two different media types, with one copy kept offsite or in the cloud. Windows provides built-in backup tools including File History, Backup and Restore, and System Image creation. Candidates should also know how to use Windows Recovery Environment for system repair and restoration tasks. Understanding recovery time objectives and the trade-offs between backup frequency, storage requirements, and recovery speed prepares candidates for scenario-based questions about designing or evaluating backup strategies.
Virtualization and Cloud Concepts
Virtualization and cloud computing have become standard topics in the A+ exam as these technologies now appear in nearly every IT environment. Candidates should understand the purpose of hypervisors and the difference between Type 1 hypervisors that run directly on hardware and Type 2 hypervisors that run on top of a host operating system. Common examples include VMware ESXi for Type 1 and Oracle VirtualBox or VMware Workstation for Type 2.
Cloud computing concepts tested in Core 2 include the three primary service models: Infrastructure as a Service, Platform as a Service, and Software as a Service. Deployment models including public, private, hybrid, and community cloud environments are also covered. Candidates should know practical use cases for each model and understand how cloud services change the support technician’s responsibilities compared to traditional on-premises environments. Virtual desktop infrastructure, or VDI, allows organizations to host desktop environments on centralized servers and deliver them to thin clients, reducing hardware costs and simplifying endpoint management.
Remote Access and Support Tools
Remote access tools are essential for modern IT support roles and receive dedicated coverage in the Core 2 exam. Remote Desktop Protocol, or RDP, allows technicians to control Windows computers remotely using a graphical interface. Candidates should know the default port number for RDP, how to enable it through System Properties, and the security risks associated with exposing RDP to the internet without proper controls in place.
Other remote access tools tested include VNC, SSH for Linux and macOS systems, and third-party solutions like TeamViewer and AnyDesk. Candidates should understand when to use each tool based on the operating system, security requirements, and network environment. Screen sharing tools integrated into operating systems, such as Quick Assist in Windows 10 and 11, provide additional remote support options that do not require third-party software installation. Understanding how to configure, use, and secure remote access tools is increasingly relevant as remote and hybrid work environments expand the demand for effective remote IT support capabilities.
Professionalism in IT Support
Professional behavior is a tested topic in the Core 2 exam that covers how technicians should interact with users, handle sensitive situations, and represent their organizations. CompTIA expects candidates to demonstrate knowledge of appropriate communication techniques including active listening, avoiding jargon, maintaining a positive attitude, and setting realistic expectations about resolution timelines. How a technician communicates often affects user satisfaction as much as the technical outcome of the support interaction.
Handling confidential and sensitive information appropriately is another professional responsibility covered in the exam. Candidates should know how to respond when they encounter private data during a support session and understand the importance of data privacy regulations in organizational contexts. Topics such as proper workstation cleanup after a support visit, not accessing files unrelated to the support task, and avoiding unauthorized software installation all reflect the professional standards that employers expect from certified technicians. These behavioral competencies distinguish skilled support professionals from those with only technical knowledge.
Environmental and Safety Procedures
Safety and environmental procedures are included in the Core 2 Operational Procedures domain and reflect real workplace requirements for IT technicians. Candidates should know how to handle hazardous materials including toner cartridges, batteries, and CRT monitors, all of which require specific disposal methods under environmental regulations. Material Safety Data Sheets, now called Safety Data Sheets, provide information about the hazards and handling requirements for chemical substances used in IT equipment maintenance.
Electrical safety is another important area that includes proper grounding techniques to prevent electrostatic discharge damage to sensitive components. Anti-static wrist straps, mats, and bags protect components during handling and transport. Fire suppression systems appropriate for server rooms, including clean agent systems that do not damage electronic equipment, differ from water-based systems used in general building areas. Candidates should also understand proper lifting techniques, ergonomic workstation setup principles, and the importance of keeping work areas free of trip hazards and cable clutter to maintain a safe environment.
Scripting and Automation Basics
Scripting and basic automation have been added to the Core 2 exam objectives to reflect the growing expectation that IT technicians possess at least introductory knowledge of automation tools. Candidates should be familiar with common scripting languages including Windows PowerShell, Command Prompt batch files, Bash for Linux environments, and Python at a very basic conceptual level. Understanding what each language is used for and in which environments it operates is more important at the A+ level than writing functional scripts from scratch.
PowerShell is particularly important for Windows environments because it provides powerful automation capabilities for tasks such as user account management, file operations, and system configuration. Candidates should recognize basic PowerShell commands and understand how scripts can automate repetitive tasks that would otherwise require manual intervention. Use cases for scripting including software deployment, log file analysis, and scheduled system maintenance demonstrate the practical value of automation in IT support roles. Even basic scripting awareness improves a technician’s ability to read, interpret, and apply scripts they encounter in enterprise environments.
