The CompTIA A+ 220-802 exam requires you to take a slightly different approach than the 801 exam. Having recently become A+ certified, I want to give you a little insight into what to expect on the 802 exam and some extra tips for success. The 220-802 exam is more challenging than many expect. It includes more interactive questions, demands deeper knowledge, and even pulls in content from the 801 exam. After completing both tests, I strongly recommend taking them as close together as possible. I had to delay my 802 exam for almost three months after passing 801 due to personal circumstances, and that break made studying more difficult.
When I returned to studying for 802, I found myself rusty on several hardware-related topics from 801. A clear example of this crossover appeared on my 802 exam in the form of a printer troubleshooting question. It asked how to resolve faded output on a laser printer, and it stated that the toner cartridge was not the problem. This meant I had to recall the function of components like the transfer corona wire, the fuser assembly, or the drum. While a hardware-related question, it showed up on a software-focused exam. This crossover demonstrates how important it is not to mentally separate the 801 and 802 content too strictly. They overlap more than many realize.
Troubleshooting is a key part of the 220-802 exam. You will face scenarios involving printers, network issues, monitor malfunctions, and boot problems. Knowing how to identify and resolve these issues is essential not just for the test but for working in IT as well. It’s not enough to just memorize solutions; understanding the reasoning and process behind troubleshooting steps is critical. The exam tests your ability to apply best practices in problem-solving, which mirrors what you’ll be expected to do on the job.
Hands-on experience is vital for success in the 220-802 exam. While you might manage to get through 801 with mostly theoretical knowledge, 802 is far more demanding in terms of practical application. There is a wide range of command-line utilities, system administration tools, and configuration tasks you need to be familiar with. Reading about them isn’t enough. Without actual practice, you may forget the sequence of steps required when performing a task. Try to experiment on your PC when you study. Of course, be careful not to make system changes on your only computer that could affect its functionality. Work within safe limits based on what resources you have.
Troublesome Topics You Should Watch Out For
Despite finding the A+ certification manageable overall, I encountered several topics during my 220-802 preparation and testing that gave me trouble. These were mostly areas I found less interesting, which meant I didn’t study them as thoroughly. It’s important to recognize the subjects that bore you and make an effort to focus on them more deliberately. Ignoring them could cause unnecessary mistakes on exam day.
Printers are one such topic for me. They can be dry and tedious, but they are covered extensively in the exam. You need to know how to manage and troubleshoot printing devices thoroughly. This includes knowing how to start and stop the spooler service, access the print queue, assign permissions, and, most importantly, troubleshoot problems. Both hardware and software components of printers come into play, so ensure you understand how they function together.
Another topic I underestimated was port numbers. While I had them down for 801, I let them slip by the time I took 802. My 802 exam included a question about mail ports, specifically IMAP, POP3, and SMTP. That was the only port-related question I saw, but just one question can be the difference between passing and failing. Don’t neglect this topic. Make sure you know the most common port numbers and their associated services. Even if they appear in only one or two questions, they are easy points if you’re well-prepared.
Windows operating system upgrade paths also tripped me up. I found it difficult to stay engaged with this topic during study sessions, but it showed up on the test. You should understand how to upgrade from one version of Windows to another, such as from XP to Vista or Vista to Windows 7. One question required me to identify whether an in-place upgrade was possible or whether a clean install would be needed. Knowing the difference and the specific upgrade paths is important because these scenarios reflect real-world IT tasks. This topic also ties into practical business decisions when rolling out OS changes across an organization.
Network configuration is another essential area. While I was comfortable with it, I recognize how it could confuse others. You need to know how to assign static IP addresses, configure DNS servers, and set alternate connection settings on a network adapter. Additionally, I encountered an interactive question related to setting up a wireless access point and another on network adapter configuration. These questions require both knowledge and a step-by-step understanding of how to perform the tasks. If you’re unfamiliar with these procedures, make time to learn them. You can practice on your system or use virtualization tools to simulate scenarios.
Preparing Effectively for the 220-802 Exam
To prepare for the 220-802 exam, prioritize practical, hands-on learning. You should spend time working directly with Windows XP, Vista, and 7. The exam may ask you about the specific path to access a system utility or administrative tool within these different operating systems. Because these paths can vary slightly between versions, real experience navigating them is essential.
During my preparation, I used XP and 7. I didn’t have access to Vista and chose not to purchase it, but I still managed to pass. That said, Vista and 7 are quite similar, so if you can work with one, you’ll have a decent understanding of the other. However, if you can get your hands on all three operating systems, do it. The more comfortable you are with their interfaces and tools, the more confident you’ll feel on the exam.
You should also be aware that the exam does not give you access to a virtual environment for testing commands or exploring tools. If you’re asked a question that requires knowledge of a utility’s file path or how to navigate through menus, you must be able to recall it from memory. This is where hands-on repetition becomes invaluable. Don’t rely solely on books or passive learning. Actively use what you learn as you go.
Troubleshooting plays a central role throughout the 220-802 exam. Whether it’s solving network problems, diagnosing printer malfunctions, or identifying boot issues, you must understand the root causes and the process for resolving them. This not only helps during the test but also forms the foundation of your practical IT skills.
Take time to evaluate your weak areas and focus your study accordingly. If a topic feels boring or overly complex, break it down into smaller parts, use visual aids, or create scenarios to help it stick. The effort you put into mastering the full scope of the 220-802 exam content will make a difference, not only in passing the exam but in becoming a capable IT professional.
Diving Deeper into Troubleshooting Techniques
A strong foundation in troubleshooting is critical for passing the CompTIA A+ 220-802 exam and for working in real-world IT environments. Unlike the 220-801, which focuses more on definitions and hardware functions, the 220-802 places you in simulated situations where you must diagnose and fix issues. These scenarios often combine software, networking, and hardware knowledge. Understanding how to systematically approach problems will give you a big advantage.
One of the key troubleshooting models to understand is the CompTIA six-step method. The first step is to identify the problem. This means gathering information, replicating the issue if possible, and observing any error messages or symptoms. The second step is to establish a theory of probable cause. You might start with the simplest explanation first, such as checking cables or power before moving on to software or deeper hardware issues.
After developing a theory, you test it in step three. If your theory is confirmed, you proceed to step four and establish a plan of action to resolve the problem. This includes considering possible side effects or risks involved in your fix. In step five, you implement the solution and verify full system functionality. Finally, in step six, you document your findings and solutions so future issues can be addressed more quickly.
This model is not only tested in theory-based questions but also appears in interactive formats where you must walk through each step using drag-and-drop tools or selecting the correct actions in simulated environments. Practicing these steps with real equipment or virtual machines is the best way to internalize them.
Importance of Hands-On Experience with Software Tools
The 220-802 exam heavily emphasizes practical software knowledge, especially in areas such as operating systems, administrative tools, command-line interfaces, and configuration panels. Reading about these tools is helpful, but using them hands-on makes a much stronger impression. You should spend time working in Windows XP, Vista, and 7 environments, as the exam covers all three.
Some tools to focus on include Device Manager, Event Viewer, Task Manager, System Configuration, and Disk Management. You should know what each tool is used for, how to access it, and what types of problems it can help solve. The exam may give you a scenario where a computer is not recognizing a device, and you will need to identify that Device Manager is the correct tool to troubleshoot it.
Command-line tools are another critical component of the exam. Commands like ipconfig, ping, chkdsk, sfc, and netstat are frequently referenced. You need to know what each command does, the parameters that modify its behavior, and which situations call for its use. Memorization is not enough. Type the commands yourself and observe the outputs.
Administrative tools often require a deeper understanding. For example, you might need to use Task Scheduler to automate a script or use Services to manage background processes. These tools are not just theory. In practice, they are essential to managing business environments, and the exam expects you to be comfortable using them. If possible, set up a test system and walk through all the available administrative tools.
Mastering User Account and Security Management
Security is another major focus area in the 220-802 exam. You must be familiar with managing user accounts, permissions, and policies. In Windows, the differences between standard users, administrators, and guests must be clearly understood. You should also know how to apply the principle of least privilege when assigning access rights to users.
You will likely be asked to configure user accounts, set password policies, and manage access to files and folders. Make sure you understand how to create and delete accounts, modify group membership, and use tools like Local Users and Groups or User Accounts in the Control Panel. Scenarios may involve a user being unable to access a network resource, and you will need to determine whether permissions or group membership are the issue.
In terms of system security, the exam expects knowledge of antivirus software, firewalls, and Windows security settings. You may need to configure Windows Firewall settings to allow or block specific applications, or troubleshoot issues where a program cannot connect to the internet. Understanding how to add exceptions and open ports is essential.
In addition to local security policies, the 220 802 covers topics like file encryption and user authentication methods. You should be familiar with EFS (Encrypting File System), NTFS permissions, and simple password rules like complexity and expiration policies. Some questions may involve setting up multi-factor authentication or recognizing scenarios where it’s appropriate.
Understanding System Recovery and Maintenance
System recovery and maintenance topics also appear frequently on the 220-802 exam. You should understand how to use tools like System Restore, Recovery Console, and Windows Backup. The exam may present you with a problem where a system fails to boot, and you will need to identify which tool or process to use to fix it.
Safe Mode is one of the most commonly tested topics in this category. You should know the different types of Safe Mode, when to use them, and how to access them. Other startup repair tools include Last Known Good Configuration and System Recovery Options. Practice navigating to these options so that the process becomes familiar.
Another tool to master is MSConfig. It allows you to control startup items and services and can be used to troubleshoot issues caused by conflicting programs or services. Disk Cleanup and Disk Defragmenter are important for maintaining performance, and you may be tested on the benefits and purposes of these utilities.
Windows Update is also part of system maintenance. Be familiar with how updates are delivered, installed, and rolled back. Questions might involve failed updates or compatibility issues caused by patches. Make sure you understand how to manage update settings and check for installed updates.
Also included in system recovery is the concept of image-based backup and restore. This allows entire system states to be captured and restored later. You may be asked how to implement a backup strategy for a small office or home office, and which tools are best suited for regular and automated backups.
Recognizing Real-World Applications of Exam Topics
The CompTIA A+ 220-802 exam does more than test technical facts. It presents real-world scenarios, and expects you to respond as if you were working in a live environment. This includes balancing time, making decisions about backup versus restore, and identifying whether an issue should be escalated or solved at the technician level.
It also tests your communication and customer service skills. You may be given a situation where a user is upset, confused, or hostile, and you must choose the most professional response. This is not just a soft skill. Knowing how to respond to frustrated users respectfully and effectively is a core expectation for IT professionals.
You might encounter scenarios where you need to document actions taken or explain procedures in non-technical language. This aligns with real help desk responsibilities where clarity and record-keeping are important. Make sure you’re comfortable switching between technical jargon and user-friendly explanations.
Some questions will test your understanding of service-level agreements and business continuity planning. These are often overlooked during study, but are part of the domain objectives. You should know how to interpret priority levels, response times, and roles in maintaining IT operations.
Environmental factors may also come up. Proper disposal of electronic waste, managing power issues, and maintaining a clean, static-free work environment are also tested. Though they may not seem central, these questions reflect professional workplace behavior and responsibility.
Exploring Advanced Networking Concepts
Networking is a vital part of the CompTIA A+ 220-802 exam. Although 801 introduced basic concepts, the 802 exam focuses on applying them in troubleshooting and configuration scenarios. Candidates need to understand not just what the components do, but how they interact in real environments.
Start by reviewing key networking devices such as routers, switches, hubs, modems, and access points. While some of these were covered in 801, the 802 exam takes it a step further. For instance, rather than just identifying a router, you may be asked how to configure it or troubleshoot a connectivity issue. Knowing how to log into a router, adjust DHCP settings, configure port forwarding, and change SSIDs and security options is essential.
You must also have a solid grasp of network addressing. Understand the structure of IPv4 addresses, subnet masks, default gateways, and DNS. It’s not enough to memorize terms. Practice identifying and fixing address conflicts, misconfigured gateways, or issues with DHCP leases. Questions may give you command-line outputs like ipconfig or ping and ask you to interpret the results.
The exam also includes interactive simulations where you are asked to configure network settings on a computer or identify what’s wrong in a given network setup. You may need to assign a static IP address, change DNS settings, or troubleshoot an inability to connect to a network share.
Wireless Technologies and Security Configurations
Wireless networking is another major focus in the 220-802 exam. You must understand both configuration and troubleshooting of wireless networks, as well as the differences between various wireless standards such as 802.11a, b, g, n, and ac. Knowing the ranges, speeds, and frequency bands used by each standard will help you choose the correct setup in exam scenarios.
You will likely see questions that require configuring a wireless access point. This includes assigning SSIDs, enabling encryption protocols, and limiting MAC address access. Be familiar with security protocols like WEP, WPA, WPA2, and the importance of AES encryption over TKIP. Questions may ask which encryption is best for a small office or how to fix a problem where a user can’t connect due to a mismatched security type.
Wireless interference is also addressed. Understand what causes poor signal quality or dropped connections. Devices like microwaves, cordless phones, or thick walls can reduce signal strength or interfere with connectivity. Questions may present signal diagrams or user complaints and ask you to diagnose the cause.
Channel overlap is a frequent issue in dense environments. For 2.4 GHz networks, knowing the non-overlapping channels (1, 6, and 11) helps optimize wireless performance. You might be asked which channel to use to minimize interference or improve performance in a crowded building.
Configuring and Troubleshooting Network Settings
Practical knowledge of configuring network settings on both Windows and mobile devices is required. You may need to demonstrate how to assign static IP addresses, configure DNS and gateway settings, or test connectivity using command-line tools. You might also be presented with a computer that can’t access the internet and be asked to fix it.
Windows tools you should know include the Network and Sharing Center, Command Prompt, and Control Panel settings for network adapters. On the command line, commands like ipconfig, ping, tracert, netstat, and nslookup often appear in questions. Learn what each command does and how it helps diagnose network problems.
Also, understand how to manage proxy settings, configure alternate network locations, and switch between DHCP and static configurations. In business environments, users may travel between locations, requiring manual changes or the use of alternate configurations. Understanding how to set these up is both practical and tested.
Networking issues with mobile devices can appear on the exam as well. Be prepared to identify why a smartphone may not connect to Wi-Fi or how to resolve Bluetooth connectivity problems. You might also be asked how to configure VPN settings on a mobile platform, including which protocols to use and how to authenticate.
Optimizing System Performance for Users
Performance optimization is another core area of the 220-802 exam. This involves identifying what is slowing a system down and applying best practices to improve it. The exam may present a scenario where a user complains about system lag, and you will need to determine whether the issue is software-based, hardware-related, or due to background processes.
You should understand how to manage startup applications using MSConfig and Task Manager. Reducing unnecessary startup entries can significantly improve boot time. The exam might include a question asking which tool to use for disabling a program from launching at startup. Be familiar with each tool’s purpose and how they differ.
Disk performance is another area tested. Know how to use Disk Cleanup and Disk Defragmenter (for spinning drives) and understand the difference between the two. While Disk Cleanup helps clear temporary files and free up space, Disk Defragmenter improves file access speeds by rearranging fragmented data. SSDs don’t need defragmentation, and doing so may reduce their lifespan, which is a key point to remember.
RAM and CPU usage monitoring are also covered. You may see a performance monitor output and be asked to interpret whether a system is running out of memory, overloaded with background processes, or facing CPU throttling. Knowing how to close background tasks and allocate resources effectively is a real-world skill that is tested on the exam.
Also covered is the Windows ReadyBoost feature, which can help improve performance on systems with limited RAM by using flash memory. This feature is mostly useful on older systems, and while you may not use it often in modern environments, it is still a tested concept.
Diagnosing Common System Errors and Crashes
The 220-802 exam also challenges your ability to resolve system crashes, application errors, and boot issues. You must understand common error messages and what actions to take in response to them. For example, if you see a blue screen or system crash, the exam may expect you to know how to view event logs, roll back drivers, or boot into Safe Mode.
Common error types include boot sector errors, missing DLLs, corrupt system files, and driver conflicts. Tools like System File Checker (sfc /scannow), chkdsk, and System Restore are your go-to solutions. You should practice using each tool so you are familiar with what it does and when it’s most appropriate.
You may also encounter situations where an operating system fails to load due to recently installed updates, incompatible drivers, or malware. In these cases, knowing how to enter Safe Mode, perform a system restore, or remove updates is vital. You should also understand when to use Last Known Good Configuration versus booting into recovery options.
Some questions may show screenshots of error messages and ask you to choose the right course of action. This includes errors like NTLDR is missing, Operating System not found, or Windows failed to start. Practice identifying these and knowing the sequence of troubleshooting steps for each.
System Imaging and Backup Solutions
System imaging plays a key role in efficient system recovery and deployment. On the CompTIA A+ 220-802 exam, you may be asked how to create, restore, or manage system images in a business environment. Imaging allows technicians to create a replica of a system’s software, settings, and configuration. This image can then be deployed to other systems, saving time and ensuring consistency.
You should understand the difference between full, incremental, and differential backups. A full backup copies everything on a system, while incremental and differential backups only save the changes since the last backup. Incremental backups are smaller and faster but require all previous backups for restoration. Differential backups grow larger over time, but simplify the recovery process since only the last full and most recent differential backups are needed.
Backup scheduling and storage strategies are also tested. You may be asked when to use on-site backups versus cloud storage. On-site backups are faster to restore, but are vulnerable to local disasters. Cloud backups offer off-site safety but may be slower depending on bandwidth. You need to understand the balance between convenience, recovery time objectives, and data protection.
Exam scenarios might present a failed drive, and you will have to decide whether to restore from backup or reimage the system. In some cases, performing a clean install followed by file restoration is the only option. Practice creating backups in Windows, using built-in utilities such as Backup and Restore, and get familiar with third-party solutions as well.
Software Deployment and Licensing Considerations
Another topic that appears in the 220-802 exam is software deployment, especially in business settings. You may be presented with a situation where multiple computers need the same applications installed, and you must choose the most efficient method. This is where system images, unattended installations, and scripted deployments come into play.
An unattended installation is a method of installing software without manual intervention. This is done using an answer file that supplies all required inputs, such as license keys and settings. This method is often used in enterprise environments for mass deployments. Be prepared to answer questions about the benefits and risks of unattended versus manual installation.
You should also understand the difference between local, network-based, and cloud installations. Local installations are common for standalone systems, while network installations allow multiple systems to access a shared installer from a central server. Cloud installations, often delivered via web portals or device management platforms, are increasingly common in modern environments.
Licensing is another element the exam may test. You must be able to distinguish between different license types, such as OEM, retail, volume, and open-source. OEM licenses are tied to the original hardware and cannot be transferred. Retail licenses can be moved from one machine to another. Volume licenses allow multiple installations using a single key but are subject to organizational agreements.
You may also need to resolve licensing conflicts. For example, if software is reporting as unlicensed after hardware changes, you should know how to reactivate it and understand the reasons behind activation failures. Understanding the tools used for activation, such as the command slmgr for Windows licensing, will support your answers in both the exam and real situations.
Introduction to Virtualization in Desktop Environments
Virtualization is a relatively newer but important topic in the A+ exam. It refers to running multiple operating systems or environments on a single physical machine through software such as hypervisors. Understanding the purpose and benefits of virtualization is essential.
You should know the difference between Type 1 and Type 2 hypervisors. Type 1 hypervisors run directly on the hardware and are used in server environments. Type 2 hypervisors run within an existing operating system and are more common in desktop or lab environments. Examples include tools like VMware Workstation and VirtualBox.
The exam may present a scenario where a technician needs to test an operating system or application without affecting the main system. In such a case, virtualization is the best solution. You must understand how to allocate CPU, RAM, and storage to a virtual machine and how to set up network connectivity inside the virtual environment.
Virtualization also plays a role in security and testing. Isolated environments can be used to safely examine potentially malicious software or troubleshoot problems without affecting the host system. Some exam questions may explore when to use virtualization and how to handle performance issues that arise from poor resource allocation.
Snapshots are another key concept. A snapshot allows you to save the state of a virtual machine so that you can revert to it later. This is especially useful in testing environments. Knowing how and when to use snapshots can help you answer practical exam questions related to configuration rollbacks or software testing.
User Education and Preventive Maintenance
The CompTIA A+ 220-802 exam also includes objectives focused on user training and preventive maintenance. These soft skills and best practices are crucial for long-term success in IT. As a technician, you are not just solving problems; you are helping users avoid them.
You should understand the importance of educating users on basic security practices. This includes recognizing phishing emails, avoiding suspicious downloads, and following safe password policies. Some exam questions may involve identifying user behavior that could put the system at risk or recommending steps to prevent issues from recurring.
In real IT environments, technicians are often required to provide short training sessions or tips during service calls. You should be able to explain technical procedures in a way that non-technical users can understand. This includes showing them how to back up files, install updates, or clean their computer safely.
Preventive maintenance tasks include regular disk cleanups, checking for updates, inspecting hardware connections, and replacing consumables like printer toner or batteries. These tasks help maintain system performance and reduce the likelihood of hardware failure. The exam may present a scenario involving a sluggish system or random crashes, and your role is to recommend and perform maintenance tasks.
Documentation is another preventive tool. Keeping records of user issues, system changes, and hardware replacements helps avoid repeated troubleshooting. On the exam, you may be asked which details to include in a service ticket or how to follow up after an incident is resolved.
Environmental awareness is tested as well. Technicians should follow proper procedures for disposing of electronics, managing cables to avoid tripping hazards, and using antistatic tools to prevent electrostatic discharge damage. These practices contribute to safety and equipment longevity.
Final Thoughts
Success on the 220-802 exam requires more than memorizing facts. You need to approach your study as if you’re preparing for real-world situations. That means combining theory with practical skills and practicing scenario-based problem solving.
Set a consistent study schedule and try to limit long gaps between the 801 and 802 exams. The material overlaps in unexpected ways, and staying fresh on hardware topics helps even with the software-focused 802. Review weak areas regularly and focus on topics that you tend to forget or find uninteresting.
Use a virtual environment or a spare machine to experiment with configurations, administrative tools, and software installations. Simulate as many exam scenarios as possible. Test yourself using interactive labs or mock exams to become familiar with how questions are presented.
If possible, practice explaining your troubleshooting steps out loud or to someone else. This will train you to think logically and communicate clearly, both of which are key skills tested indirectly on the exam.
On exam day, manage your time carefully. Read each question thoroughly and watch for details that guide your answer. Eliminate wrong choices and remember that some questions are based on best practices, not just what works.
Finally, remain calm and confident. The exam is designed to reflect realistic knowledge and skills. If you’ve practiced the tools, reviewed the concepts, and engaged with the material, you’ll be prepared not just to pass the test but to succeed in your IT career.
