The CompTIA A+ Certification Exam: Core 2 (220-1202) validates your ability to support, maintain, and troubleshoot computing devices and networks in real-world environments. This exam is the second part of the CompTIA A+ credential and focuses on practical skills that IT support professionals use daily. Whether you're preparing for your first IT role or advancing your career, this page provides a clear roadmap of what to study and how to prepare effectively. We'll walk you through the exam syllabus, question formats, and actionable study strategies to help you pass with confidence.
Use this topic map to guide your study for CompTIA 220-1202 (CompTIA A+ Certification Exam: Core 2) within the CompTIA A+ path.
The 220-1202 exam uses multiple question types to measure both foundational knowledge and the ability to apply that knowledge in realistic scenarios. Questions progress in difficulty and emphasize practical decision-making over memorization.
Questions increase in complexity as you progress, requiring you to integrate knowledge from multiple topic areas to solve practical problems.
An effective study plan breaks the syllabus into manageable weekly goals, combines passive learning with active practice, and includes timed simulations to build test-day readiness. Aim to spend 4-6 weeks on structured study, allocating more time to areas where you have less hands-on experience.

Operating Systems and Security typically represent the largest portion of the exam, reflecting their importance in daily IT support work. However, all four domains are tested, so a balanced study approach is essential. Review the official CompTIA exam objectives to see the exact percentage breakdown and adjust your study time accordingly.
These topics overlap constantly in practice. For example, applying security patches (Security + Operating Systems) requires following change management procedures (Operational Procedures) and may involve troubleshooting compatibility issues (Software Troubleshooting). Understanding these connections helps you answer scenario-based questions and prepares you for actual IT support roles where you juggle all four areas simultaneously.
Hands-on experience with at least one Windows system and basic familiarity with macOS or Linux is valuable but not required to pass. Prioritize labs that let you practice user account creation, apply security settings, install and remove software, and use command-line tools. Virtual machines are affordable and safe for learning; focus on tasks you'll perform in the exam scenarios rather than advanced administration.
Many candidates rush through scenario questions without reading all answer options carefully, miss details about user roles or organizational policies, or confuse similar troubleshooting steps. Others underestimate Operational Procedures, treating it as less important than technical topics. Slow down, read each scenario fully, and remember that the "best" answer often depends on context like budget, security requirements, or company policy.
Take a full-length practice test under exam conditions (same time limit, quiet environment) and review every question, not just the ones you missed. Spend remaining days reviewing weak topic areas and re-reading explanations from practice materials. Avoid cramming new content; instead, focus on reinforcing what you've already learned. Get adequate sleep the night before the exam to ensure you're sharp and focused.
A technician needs to provide remote support for a legacy Linux-based operating system from their Windows laptop. The solution needs to allow the technician to see what the user is doing and provide the ability to interact with the user's session. Which of the following remote access technologies would support the use case?
The correct answer isVNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user's session.
A . VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.
C . SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.
D . RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.
CompTIA A+ 220-1102 Core 2 Objective Reference:
Objective 1.8 -- Given a scenario, use features and tools of the operating system.
Under this objective, candidates are expected to be familiar with remote access technologies, includingRDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.
A company requires technicians to verify that files downloaded from the internet have not been modified. Which of the following should the technicians use for validation?
The correct answer is A. Hashing, because hashing is specifically designed to verify file integrity and detect whether a file has been altered after its original creation or distribution. A hash is a fixed-length value generated by running a file through a hashing algorithm such as SHA-256 or SHA-1. Even a single-bit change in the file will produce a completely different hash value.
According to the Quentin Docter -- CompTIA A+ Complete Study Guide, hashing is commonly used to validate downloaded software by comparing the calculated hash of the downloaded file with the hash published by the vendor. If the two values match, the technician can be confident that the file has not been modified or tampered with.
The Travis Everett & Andrew Hutz -- All-in-One Exam Guide emphasizes that hashing ensures integrity, not confidentiality or authentication. SSL certificates secure data in transit, but they do not validate files after download. Plug-ins and extensions provide additional browser functionality but have no role in verifying file integrity.
The Mike Meyers / Mark Soper Lab Manual reinforces that hashing is a standard best practice in secure software deployment and malware prevention. It allows technicians to confirm that files are exactly as the publisher intended.
Because the requirement is to confirm that files have not been modified, hashing is the correct and most reliable method, making A the correct answer.
A user is unable to use the latest version of an app on a legacy tablet. What is the most likely reason?
Older tablets may not support newer app versions due toincompatible or unsupported operating systems. App developers often drop support for outdated OS versions.
FromTravis Everett -- CompTIA A+ All-in-One Exam Guide:
''When an app won't install on an older device, check the OS version. Most apps require a minimum OS level for compatibility and security.''
An organization sees unauthorized apps installed and licensing prompts. What should the security team do?
Removing users from the local admin group prevents them from installing unauthorized software.
From Quentin Docter -- Complete Study Guide:
''Local admin privileges allow users to install unauthorized apps. Removing them from this group restricts installations and helps prevent malware.'' .
Which of the following is an example of an application publisher including undisclosed additional software in an installation package?
A Potentially Unwanted Program (PUP) is software that a user may not have knowingly installed. It often gets bundled with legitimate software and installs without full disclosure. PUPs can affect performance, change system settings, or display unwanted ads but are not necessarily malicious like viruses or ransomware.
A . Viruses replicate and spread; they are generally more harmful and not 'bundled' in the same way.
B . Ransomware encrypts files for payment and is deliberately malicious.
D . A Trojan disguises itself as legitimate software to perform malicious actions but is not typically pre-bundled by legitimate publishers.
CompTIA A+ 220-1102 Objective 2.5: Given a scenario, detect, remove, and prevent malware using appropriate tools and methods.
