The CompTIA A+ Certification Exam: Core 1 (2026) validates your foundational knowledge and hands-on skills in IT support and troubleshooting. This exam, identified as 220-1201, is the first step in the CompTIA A+ certification path and is designed for entry-level IT professionals, help desk technicians, and aspiring systems administrators. This page provides a clear roadmap of exam topics, question formats, and practical preparation strategies to help you study efficiently and build confidence for test day.
Use this topic map to guide your study for CompTIA 220-1201 (CompTIA A+ Certification Exam: Core 1 (2026)) within the CompTIA A+ path.
The 220-1201 exam uses multiple question types to assess both theoretical knowledge and practical decision-making ability. Questions progress in difficulty and reflect real-world scenarios you will encounter in IT support roles.
Each question type emphasizes practical reasoning; you are expected to not only know facts but also apply them to solve problems and make informed decisions under realistic constraints.
Effective preparation for 220-1201 requires structured study that maps topics to your schedule and builds confidence through practice. Allocate time proportionally to each domain, with extra focus on hardware and troubleshooting, which typically carry greater weight on the exam.

Hardware and Hardware and network troubleshooting typically account for a larger percentage of exam questions, reflecting their importance in day-to-day IT support. However, all five domains are tested, and you should study each thoroughly. The CompTIA A+ exam blueprint provides the exact percentage breakdown for each topic, which guides your time allocation.
In practice, these domains overlap constantly. For example, when a user reports a slow mobile device, you apply knowledge of mobile hardware and networking to diagnose the issue. Virtualization and cloud concepts influence how companies deploy resources and support remote work. Understanding these connections helps you grasp why each topic matters and improves retention during study.
CompTIA recommends 9-12 months of IT support experience, but many candidates pass with less if they study effectively and practice with labs. Hands-on experience with hardware assembly, network configuration, and troubleshooting tools significantly boosts confidence and understanding. If you lack experience, prioritize lab work with virtual machines, network simulators, and hardware components to bridge the gap.
Many candidates rush through scenario questions without fully reading the symptoms, leading to incorrect root cause analysis. Others confuse similar technologies (for example, cloud service models or network protocols) due to insufficient review of explanations. Misunderstanding the difference between hardware specifications and actual performance needs also causes errors. Slow down, read carefully, and always understand why one answer is better than others.
In the final week, stop learning new material and focus on review and practice. Take a full-length timed test, analyze weak areas, and drill scenario-based questions in those domains. Spend time on terminology and troubleshooting decision trees rather than deep dives into new topics. Get adequate sleep and manage test anxiety by familiarizing yourself with the exam interface and time limits.
A desktop can connect to a file server but cannot access the internet. The ipconfig /all output shows a correct IP and DNS but no default gateway. What will most likely restore internet access?
CompTIA A+ teaches that the default gateway is required for any device to communicate with external networks such as the internet. Without a configured default gateway, the computer can communicate only with devices on the same local subnet explaining why the file server is reachable.
DNS and IPv6 settings are not the issue; without a gateway, external routing cannot occur. Flushing DNS affects hostname resolution, not routing. NetBIOS settings have no effect on internet connectivity.
Adding or correcting the default gateway (usually the router's LAN IP, such as 192.168.1.1) will allow the PC to route traffic beyond its local network.
This aligns precisely with CompTIA's troubleshooting steps for missing or incorrect gateway configuration.
A technician is troubleshooting a connectivity issue on a network computer. The technician runs ipconfig in a command prompt and receives the following IP address:169.254.0.6. Which of the following is most likely the type of IP address being assigned?
An IP address starting with169.254.x.xis aself-assigned address(also calledAPIPA-- Automatic Private IP Addressing). It's used when a client device cannot contact a DHCP server. This address allows limited communication on the local network segment butno internet access.
Option A:DHCP reservations assign specific IPs from the DHCP server they don't result in APIPA.
Option B:Dynamic assignment from DHCP assigns valid IPs in the proper subnet, not 169.254.x.x.
Option D:Static IPs are manually set and would not fall in the 169.254.x.x range unless set incorrectly.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 2.6: Given a scenario, configure and troubleshoot network connectivity.
Which of the following is used to verify if a NIC port can send and receive data?
The correct answer is A. Loopback plug.
According to CompTIA A+ Core 1 220-1201 objectives under Networking:
A loopback plug is used to test a network interface card (NIC) port by sending a signal out of the port and back into the same port, verifying that the NIC can send and receive data properly.
This is a common diagnostic tool when troubleshooting network connectivity issues on individual devices.
Why the other options are incorrect:
B . Toner probe: Used for tracing and locating cables, not for testing NIC ports.
C . Cable tester: Checks the integrity of network cables but does not verify NIC send/receive functionality.
D . Network tap: Passively monitors network traffic but does not test the NIC port itself.
CompTIA A+ Core 1 (220-1201) Exam Objectives -- Networking: ''Given a scenario, use tools such as loopback plugs and cable testers to verify network connectivity.''

Which storage device is best suited for a high-performance gaming laptop requiring fast data access?
Gaming laptops prioritize speed, low latency, fast read/write times, and quick loading. CompTIA A+ explains that NVMe M.2 SSDs provide the fastest consumer storage available due to their use of the PCIe bus, which delivers significantly higher performance compared to SATA-based drives.
HDDs (Options A and C) are mechanical and have slow seek times, making them unsuitable for high-performance gaming. SAS SSDs (Option D) are enterprise-grade, rarely used in laptops, and require SAS controllers not found in consumer systems.
Thus, a 512GB NVMe M.2 SSD offers the best performance, fastest boot times, rapid texture loading, and optimal gaming responsiveness fully aligning with A+ hardware performance recommendations.
Which of the following cloud models allows an organization to have exclusive access to cloud resources?
A private cloud provides cloud resources that are dedicated to a single organization, giving that organization exclusive use of the underlying infrastructure. This model is selected when a company needs tighter control over security, compliance, performance, and customization than what is typically available in a multi-tenant public cloud environment. Private cloud resources can be hosted on-premises in the organization's own data center or hosted by a third party, but the key point is exclusive access---the hardware and cloud environment are not shared with unrelated customers.
A public cloud is shared among multiple customers (multi-tenant), so it is not exclusive. A hybrid cloud combines two environments, usually a private cloud and a public cloud, which can help with flexibility and scaling, but it is not defined as exclusive because part of it may be public. A community cloud is shared by organizations with common needs (such as similar compliance requirements), meaning it is shared among multiple entities rather than exclusive to one organization. Therefore, the cloud model that provides exclusive access to resources is Private.
