CompTIA A+ Core 1 (220-1101) is the first exam in the two-part A+ certification series, validating foundational IT skills essential for entry-level technical support roles. This exam measures competency in hardware components, networking protocols and configuration, mobile device management, virtualization concepts, and troubleshooting methodologies. Core 1 focuses on the infrastructure and hardware foundations that support modern IT environments, while its companion exam (Core 2) addresses operating systems, security, and operational procedures. The certification is widely recognized by enterprises and government agencies, including DoD 8140 approval for technical support specialist and cybersecurity infrastructure roles.
CompTIA A+ Core 1 is designed for IT professionals pursuing foundational certification in technical support and IT operations. Target roles include IT support specialists, help desk technicians, technical support specialists, junior system administrators, and cyber defense infrastructure support specialists. Candidates typically have 12 months of hands-on experience in IT support roles, though the exam is accessible to those with formal training and self-study. This certification serves as an entry point into IT careers for individuals transitioning from other fields or those seeking to validate self-taught technical knowledge.
CompTIA recommends 12 months of hands-on experience in an IT support specialist job role before attempting the exam, though this is not a formal requirement. Candidates should have foundational knowledge of hardware components, basic networking concepts, and familiarity with Windows operating systems. Practical experience troubleshooting computers, printers, mobile devices, and SOHO networks is strongly beneficial. Those without direct experience can prepare through formal training, online courses, CompTIA study guides, and hands-on lab environments that simulate real-world IT support scenarios.
Core 1 features a maximum of 90 questions delivered in 90 minutes, with a passing score of 675 out of 900 points. Question types include multiple-choice (single answer and multiple response), drag-and-drop, and performance-based questions that simulate real IT troubleshooting tasks. The exam is administered through Pearson VUE testing centers both online and in-person. Performance-based questions require candidates to perform actual tasks such as installing hardware, configuring network settings, or troubleshooting systems within a virtual environment. The exam does not include unscored survey questions.
CompTIA A+ certification significantly enhances career prospects in IT support and technical roles. A+ certified professionals earn an average of $63,909 annually in the United States, with salaries ranging from $49,000 to over $101,000 depending on experience, location, and industry. The certification is required by numerous federal government agencies including DoD and Department of Homeland Security for specific pay grades and positions, creating substantial job opportunities in the government/defense sector which pays 20-30% above average. The Bureau of Labor Statistics projects approximately 50,500 annual job openings in technical support roles, making A+ certification a valuable credential for entering this market. Holding A+ certification demonstrates employer-valued technical competency and serves as a stepping stone to advanced certifications including Network+, Security+, and specialized cybersecurity credentials that can increase earning potential by $10,000-$15,000 or more.

Preview — answers shown1. A technician at Litware is building a workstation for a video editor who requires the fastest possible external storage connection for editing 8K video files directly from an external SSD enclosure. The workstation's motherboard has USB-C ports. Which interface standard provides the highest throughput for this use case? (Select one!)
Explanation
Thunderbolt 4 provides the highest throughput at 40 Gbps and uses the USB-C connector, making it the ideal choice for high-bandwidth external storage workflows like 8K video editing. Thunderbolt 4 guarantees minimum performance specifications including 32 Gbps PCIe tunneling for storage devices. USB 3.2 Gen 2x2 at 20 Gbps provides half the bandwidth of Thunderbolt 4 and is less common in professional workstations. USB 3.2 Gen 2 at 10 Gbps would create a bottleneck for 8K video editing workflows. USB 2.0 at 480 Mbps is completely inadequate for any modern high-bandwidth storage application.
2. A technician at Litware needs to identify a specific Ethernet cable that runs from a server room through a wall to a conference room two floors below. The cable is bundled with dozens of other cables in the ceiling. Which networking tool should the technician use? (Select one!)
Explanation
A toner probe, also known as a fox and hound or tone generator and inductive probe set, is the correct tool for tracing and identifying a specific cable within a bundle. The tone generator is attached to one end of the cable and sends an electrical signal. The inductive probe is then used at the other end or along the cable run to detect the tone, allowing the technician to identify the specific cable without disconnecting other cables. A Wi-Fi analyzer detects wireless signals and cannot identify physical Ethernet cables. A cable tester verifies continuity and proper wiring but requires access to both ends of the cable simultaneously. A loopback plug tests port functionality by looping transmit signals back to receive but does not help identify a cable in a bundle.
3. A technician at Tailspin Toys is helping a user choose between two laptop models for graphic design work. Laptop A has a TN panel and Laptop B has an IPS panel. The user requires accurate color reproduction and wide viewing angles for client presentations. Which two characteristics make the IPS panel the better choice for this user? (Select two!)
Multiple correct answersExplanation
IPS (In-Plane Switching) panels provide the widest viewing angles among LCD technologies, typically up to 178 degrees with minimal color shift, making them ideal for client presentations where multiple people view the screen from different positions. IPS panels also deliver excellent color accuracy and consistency, which is critical for graphic design work where precise color reproduction affects the quality of deliverables. TN panels have the fastest response times at approximately 1ms, not IPS panels, which typically have 4-5ms response times. VA panels offer the highest contrast ratios among LCD technologies, not IPS. Power consumption varies by panel but IPS panels do not have a significant power advantage over other panel types.
4. A technician at Northwind Traders needs to set up a receipt printer for a retail point-of-sale system. The printer must produce receipts quickly, operate with minimal noise, and have low ongoing consumable costs. Which printer technology should the technician select? (Select one!)
Explanation
Direct thermal printers are the standard choice for point-of-sale receipt printing. They use heat-sensitive paper and a thermal print head to create images without any ink, toner, or ribbon consumables, resulting in very low ongoing costs. They print quickly and operate nearly silently. Laser printers are too large, expensive, and unnecessary for receipt printing. Inkjet printers have high consumable costs and slower output for this use case. Impact dot matrix printers are noisy due to pins striking a ribbon against paper and are primarily chosen when multipart carbon-copy forms are needed, which is not a requirement for standard retail receipts.
5. A field technician at Northwind Traders is setting up a new office and needs to identify which specific Ethernet cable among dozens of unlabeled cables running through the walls connects to the conference room's wall jack. Which networking tool should the technician use? (Select one!)
Explanation
A toner probe, also known as a fox and hound kit, is specifically designed to trace and identify individual cables within bundles. The tone generator is connected to one end of the cable at the wall jack, and the inductive probe is used to identify the same cable at the other end by detecting the audible tone through the cable's insulation. A cable tester verifies continuity and correct pin wiring but requires access to both ends of a known cable — it cannot identify an unknown cable in a bundle. A Wi-Fi analyzer measures wireless signal strength and channel utilization and has no function for tracing physical cables. A loopback plug tests whether a network port can send and receive data by routing the transmit signal back to the receive pins.
