Two Exam Structure Explained
The CompTIA A+ certification requires candidates to pass two separate exams, the 220-1101 and the 220-1102, both of which must be passed to earn the credential. This two-exam structure allows the certification to cover a broader range of technical content than would be practical in a single exam without requiring candidates to rush through complex topics. The 220-1101 exam focuses primarily on hardware technologies, networking fundamentals, mobile devices, and cloud computing concepts. The 220-1102 exam concentrates on operating systems, security, software troubleshooting, and operational procedures. Together the two exams provide comprehensive coverage of the full scope of knowledge required for a competent IT support professional.
Each exam consists of a maximum of 90 questions that must be completed within 90 minutes, and both exams include a combination of multiple-choice questions and performance-based questions. The passing score for both exams is 675 on a scale of 100 to 900. Performance-based questions simulate real IT support tasks and require candidates to demonstrate practical skills in a controlled environment, such as connecting cables correctly in a simulated network diagram, configuring settings in a simulated operating system interface, or diagnosing a problem based on presented symptoms. Candidates should plan to prepare for and take both exams within a reasonable timeframe of each other to avoid the knowledge from the first exam fading before they attempt the second.
Hardware Component Identification
Hardware knowledge is a cornerstone of the CompTIA A+ curriculum and the 220-1101 exam tests it extensively across a wide range of component types and form factors. Candidates must be able to identify, describe, and explain the function of core system components including central processing units, random access memory, motherboards, power supplies, storage devices, graphics cards, and expansion cards. This knowledge extends beyond simply knowing what each component does in isolation to understanding how components interact with each other and how the specifications of one component affect the selection and performance of others. A processor’s thermal design power rating, for example, directly influences the cooling solution and power supply requirements for a system build.
Motherboard form factors and their associated slot types, connectors, and chipset features are a specific hardware topic that the exam tests in practical detail. Candidates must be able to identify different expansion slot types including PCIe in its various configurations, recognize different memory slot types, and understand the purpose of various onboard connectors for storage, front panel connections, and peripheral devices. The BIOS and UEFI firmware interfaces are also covered in depth, including how to access and navigate firmware settings, configure boot order, enable or disable hardware features, and apply firmware updates. Candidates who have experience building or upgrading desktop computers will find much of this hardware content familiar, while those who have worked primarily with laptops or pre-built systems should invest additional time in developing hands-on familiarity with desktop hardware components.
Laptop and Mobile Device Skills
Laptops and mobile devices represent a significant portion of the 220-1101 exam content and require candidates to develop knowledge that differs meaningfully from desktop hardware skills. Laptop components are designed for compact form factors, low power consumption, and integrated functionality, which creates maintenance and upgrade challenges that do not exist in desktop environments. Common laptop maintenance tasks covered in the exam include replacing batteries, upgrading RAM in systems where it is accessible, replacing storage drives, and cleaning cooling systems that have become clogged with dust and debris. Candidates should understand how to access laptop components safely, including the precautions required to avoid damaging fragile ribbon cables and proprietary connectors.
Mobile device technologies including smartphones and tablets are covered in the A+ curriculum with emphasis on the support and connectivity topics most relevant to IT professionals. Candidates must understand the different mobile operating system platforms, including iOS and Android, and the basic configuration and troubleshooting tasks associated with each. Mobile device connectivity technologies including cellular data networks, Wi-Fi, Bluetooth, and Near Field Communication are tested in terms of their appropriate use cases and common configuration issues. Mobile device management concepts, including how organizations use MDM solutions to configure, monitor, and secure employee devices remotely, are an increasingly important topic in the curriculum that reflects the growing role of mobile devices in enterprise environments.
Networking Fundamentals Coverage
Networking is a substantial component of the 220-1101 exam and covers the foundational networking knowledge that IT support professionals need to perform their daily responsibilities effectively. Candidates must understand the TCP/IP networking model and the protocols that operate at each layer, including Ethernet at the physical and data link layers, IP addressing and routing at the network layer, and application-layer protocols like HTTP, HTTPS, DNS, DHCP, and FTP. IPv4 addressing including the calculation of subnet masks and the identification of network, broadcast, and host addresses is tested at a practical level that requires candidates to work through addressing problems rather than simply recalling definitions.
Network hardware devices including routers, switches, access points, firewalls, and network-attached storage are covered in terms of their functions, appropriate placement in network architectures, and basic configuration concepts. Wireless networking technologies receive particular attention in the current version of the exam, including the different 802.11 standards and their associated frequency bands, maximum speeds, and practical range characteristics. Cable types and their appropriate applications are a practical hardware topic that covers the differences between various categories of Ethernet cable, coaxial cable, fiber optic cable, and their associated connectors. Candidates who have little hands-on networking experience should supplement their reading with practice in a home lab environment where they can configure basic network equipment and observe how different settings affect network behavior.
Cloud Computing Fundamentals
Cloud computing received significantly expanded coverage in the 2022 version of the A+ curriculum, reflecting how central cloud services have become in modern IT environments. The exam tests candidates on the fundamental concepts of cloud computing including the different service models of IaaS, PaaS, and SaaS, the public, private, hybrid, and community deployment models, and the characteristics that define cloud environments such as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. These concepts are tested at a conceptual level appropriate for an entry-level certification, providing a foundation that candidates can build upon if they choose to pursue more advanced cloud certifications later in their careers.
Practical cloud topics that appear in the exam include the use of cloud-based file storage and synchronization services, cloud-based application delivery, virtual desktop infrastructure, and the basic security considerations that apply when users access cloud services from corporate devices. The concept of software-defined networking as it applies to cloud environments is introduced in the curriculum, along with the basics of how virtual machines and containers are used in cloud platforms. Candidates who regularly use cloud services in their personal or professional lives will find many of these concepts intuitively familiar, while those who have had limited cloud exposure should invest time in exploring the free tier services offered by major cloud providers to develop practical familiarity with cloud interfaces and concepts.
Windows Operating System Mastery
The Windows operating system receives the most extensive coverage of any software topic in the CompTIA A+ curriculum, reflecting its dominant position in enterprise desktop and laptop environments. The 220-1102 exam tests candidates on Windows 10 and Windows 11, covering installation procedures, upgrade paths, edition differences, and the administrative tools used to manage and troubleshoot Windows systems. Candidates must be comfortable navigating the Windows interface and using built-in administrative tools including the Control Panel, Settings app, Computer Management console, Device Manager, Task Manager, Registry Editor, and the various command-line tools that provide access to system information and configuration options.
Windows command-line proficiency is a specific skill area that the exam tests with practical questions that require candidates to know the syntax and purpose of commonly used commands. Commands like ipconfig, ping, tracert, netstat, nslookup, diskpart, chkdsk, sfc, and gpupdate are all referenced in the exam objectives and may appear in performance-based questions that require candidates to select or use the appropriate command for a given administrative task. File system concepts including NTFS permissions, file and folder sharing, and the differences between FAT32 and NTFS are also covered. Candidates should practice using the Windows command prompt regularly during their preparation to develop the command-line fluency that the exam requires.
Linux and macOS Fundamentals
While Windows receives the most coverage in the A+ curriculum, Linux and macOS are both included as operating system topics that candidates must understand at a foundational level. Linux knowledge tested in the exam focuses on the command-line interface and the basic administrative tasks that IT support professionals most commonly encounter, including navigating the file system, managing files and directories, viewing and editing text files, managing processes, and understanding file permissions. The Linux file system hierarchy is a specific topic that candidates should study, understanding the purpose of key directories like home, etc, var, and usr. Basic package management concepts and the differences between major Linux distributions are also relevant to the exam.
macOS appears in the A+ curriculum primarily in the context of support tasks rather than deep administrative knowledge. Candidates should be familiar with the macOS interface, the basic configuration options available through System Preferences, the Finder file management application, and the Terminal for command-line access. Common macOS support tasks covered in the exam include setting up network connectivity, configuring user accounts, managing software through the App Store and direct installation, and performing basic troubleshooting steps. Candidates who use macOS personally will find this section of the curriculum straightforward, while those without macOS experience should spend time with the operating system in a hands-on setting to develop familiarity with its interface and administrative tools.
Security Concepts and Implementation
Security is one of the most heavily weighted topics in the 220-1102 exam and covers both the conceptual frameworks and practical implementation skills required for IT support professionals to contribute meaningfully to organizational security efforts. The exam tests candidates on common security threats including malware types such as viruses, worms, trojans, ransomware, spyware, and rootkits, as well as social engineering attacks like phishing, vishing, smishing, and tailgating. Understanding how these threats work and how they are detected is important context for the remediation skills that the exam also tests.
Physical security controls are covered alongside logical security measures, reflecting the reality that physical access to IT equipment represents a fundamental security risk that technical controls alone cannot address. Badge readers, biometric access controls, security cameras, locking cable locks, and privacy screens are all physical security measures that appear in the exam content. Logical security controls including strong password policies, multi-factor authentication, account lockout policies, encryption, and the principle of least privilege are tested in the context of their practical implementation in Windows and other environments. Candidates should understand not only what each security control does but also how to implement it in a real system and how to verify that it is functioning as intended.
Malware Removal Procedures
Malware removal is a practical skill that IT support professionals encounter regularly and the CompTIA A+ exam tests the specific steps required to identify and remove malware from infected systems effectively. The exam follows a defined malware removal process that begins with identifying and researching malware symptoms, then quarantining the infected system by disconnecting it from the network to prevent further spread. Disabling System Restore before beginning removal prevents the malware from hiding in restore points that could reinfect the system after cleaning. Scanning the system with updated malware removal tools in safe mode, where many malware programs cannot run, is the next step in the process.
After removing identified malware, the process continues with scheduling additional scans to confirm complete removal, re-enabling System Restore, creating a new restore point from the clean system state, and educating the user about the behaviors that led to the infection. Candidates must know this process in its correct sequence because exam questions frequently present the steps in a jumbled order and ask candidates to arrange them correctly or identify which step should come next in a given scenario. Beyond the procedural knowledge, candidates should understand the characteristics of different malware types and how the appropriate removal approach may differ depending on the specific type of infection encountered. Rootkits, for example, may require specialized removal tools or even a complete operating system reinstallation because of how deeply they embed themselves in the system.
Troubleshooting Methodology Practice
Troubleshooting methodology is a topic that runs throughout both A+ exams and reflects CompTIA’s emphasis on systematic problem-solving as a core professional competency for IT support professionals. The CompTIA troubleshooting methodology consists of six steps that guide technicians from initial problem identification through final documentation. The steps are identifying the problem by gathering information and questioning the user, establishing a theory of probable cause, testing the theory to determine the actual cause, establishing a plan of action and implementing the solution, verifying full system functionality and implementing preventive measures, and documenting findings, actions, and outcomes. Each step serves a specific purpose in the diagnostic process and skipping steps often leads to inefficient troubleshooting and incomplete resolutions.
The documentation step is one that inexperienced technicians most commonly skip, but the exam treats it as equally important to the technical diagnostic steps. Good documentation creates an organizational knowledge base that helps future technicians resolve similar problems more quickly and provides a record of changes made to systems that can be invaluable when diagnosing future problems. Candidates should practice applying the troubleshooting methodology to realistic IT support scenarios during their preparation rather than simply memorizing the six steps as an abstract list. The exam presents troubleshooting scenarios and asks candidates to identify the most appropriate next action, which requires understanding the logic behind each step and being able to apply that logic to novel situations.
Virtualization Technology Basics
Virtualization is a topic that has grown in prominence in the A+ curriculum as virtual machines have become increasingly common in both enterprise IT environments and end-user computing contexts. The exam tests candidates on the fundamental concepts of virtualization including how hypervisors allow multiple virtual machines to share physical hardware resources, the differences between Type 1 and Type 2 hypervisors, and the common use cases for virtual machines in IT support contexts. Virtual machines are widely used for software testing, development environments, legacy application support, and sandboxed security analysis, and IT support professionals are frequently called upon to create, configure, and troubleshoot virtual machine environments.
Resource requirements for virtualization are a practical topic that the exam covers in the context of recommending appropriate hardware configurations for systems that will run virtual machines. Running multiple virtual machines simultaneously places significantly higher demands on processor, memory, and storage resources than running a single operating system, and candidates must understand how to assess whether a given physical system has adequate resources to support a virtualization workload. Snapshots, which capture the complete state of a virtual machine at a point in time and allow the system to be rolled back to that state if needed, are a specific virtualization feature that the exam covers in terms of both their appropriate use cases and their potential drawbacks when used incorrectly or excessively.
Operational Procedures and Professionalism
Operational procedures and professionalism form a distinct topic area in the 220-1102 exam that is sometimes overlooked by candidates who focus exclusively on technical content. This domain covers the non-technical aspects of IT support work that are equally important to professional effectiveness, including workplace safety, environmental awareness, communication skills, and professional conduct. Safety procedures covered in the exam include electrostatic discharge prevention, proper handling of equipment to avoid physical damage, safe disposal of hazardous materials like batteries and toner cartridges, and physical safety practices when working in data center environments or with electrical equipment.
Communication and professionalism topics test candidates on behaviors that define effective IT support interactions, including how to communicate technical information clearly to non-technical users, how to manage difficult customer interactions professionally, and how to prioritize and manage multiple support requests effectively. Active listening skills, setting appropriate expectations about resolution timelines, following up with users after resolving issues, and maintaining a respectful and patient demeanor even in frustrating situations are all professional behaviors that the exam addresses. Change management procedures, which govern how changes to IT systems are proposed, approved, implemented, and documented in enterprise environments, are another operational topic that candidates must understand. These non-technical topics may account for a meaningful portion of exam questions and should receive appropriate study attention alongside the more technically intensive content areas.
Remote Support Technologies
Remote support has become one of the most essential capabilities in modern IT support, and the 2022 A+ curriculum reflects this by including it as a specific topic area that covers both the technologies and the practices involved. Remote desktop tools allow IT support technicians to view and control end-user systems from a remote location, enabling them to diagnose and resolve software problems without requiring physical access to the affected machine. Windows Remote Desktop Protocol, VNC, and third-party remote support platforms are all referenced in the exam content. Candidates must understand how to configure remote access, connect to remote systems, and navigate the security considerations involved in allowing remote access to corporate systems.
Remote support introduces unique challenges that do not exist in in-person support scenarios, and the exam tests candidates on how to manage these challenges professionally. Communicating clearly with a user who cannot see what the technician is doing requires more explicit verbal guidance and greater patience than in-person support. Obtaining and documenting proper authorization before accessing a user’s system remotely is an important professional and security practice that the exam emphasizes. Virtual private network connectivity is often required for remote support in enterprise environments, and candidates should understand the basic concepts of VPN technology and how it provides secure remote access to corporate network resources for both support technicians and end users working from remote locations.
Study Strategy and Resources
Developing an effective study strategy for the CompTIA A+ certification begins with a thorough review of the official exam objectives for both the 220-1101 and 220-1102 exams, which are available for free on the CompTIA website. These objectives define exactly what knowledge and skills are tested on each exam and should serve as the primary organizing framework for all study activities. Candidates who begin their preparation without reviewing the exam objectives risk spending significant time on topics that are not tested while potentially neglecting areas that are heavily weighted in the exam. Mapping existing knowledge against the objectives and identifying gaps is the most efficient way to allocate preparation time.
Professor Messer’s free CompTIA A+ course, available on his website and YouTube channel, is one of the most popular and highly regarded study resources for A+ candidates and covers all exam objectives in clear and accessible video lessons. The official CompTIA A+ study guide and the Mike Meyers CompTIA A+ certification all-in-one exam guide are widely recommended written resources that provide comprehensive coverage of the curriculum. Practice exams from reputable providers are essential preparation tools that help candidates assess their readiness, identify remaining knowledge gaps, and develop the time management skills needed to complete the exam within the allotted time. Hands-on practice with real hardware and software remains the most effective complement to any written or video study resource, and candidates should seek out opportunities to work with actual computers, peripherals, and operating systems throughout their preparation period.
Career Pathways After Certification
Earning the CompTIA A+ certification opens the door to a wide range of entry-level IT career opportunities that provide valuable experience and serve as launching pads for long-term career growth in the technology industry. Common entry-level roles that A+ certified professionals pursue include help desk technician, IT support specialist, desktop support analyst, field service technician, and technical support representative. These roles provide hands-on experience with the technologies covered in the A+ curriculum and expose new professionals to the organizational and communication realities of IT support work in ways that certification preparation alone cannot replicate. The practical experience gained in these roles accelerates professional development significantly.
The A+ certification also establishes a foundation for pursuing more advanced certifications as career goals and interests become clearer. CompTIA’s own certification pathway suggests Network+ and Security+ as natural progressions from A+ for professionals interested in networking or cybersecurity specializations respectively. The Server+ and Cloud+ certifications are relevant for those drawn toward infrastructure roles. Vendor-specific certifications from Microsoft, Cisco, and other major technology companies become more accessible after earning A+, as the foundational knowledge it provides reduces the learning curve for more specialized content. Many IT professionals look back on their A+ certification as the credential that started everything, and the discipline developed during A+ preparation creates habits of structured learning that serve them throughout careers that may span decades and multiple technology generations.
