CompTIA A+ Practice Test (220-1101 & 220-1102): 100 Core Hardware & OS Questions

CompTIA A+ Practice Exam: Core 1 (220-1101) & Core 2 (220-1102)

Prepare to launch your IT support career with this comprehensive 100-question CompTIA A+ practice test. Covering both Core 1 (hardware, cloud, and networking) and Core 2 (operating systems, security, and operational procedures), this assessment verifies the troubleshooting fundamentals expected of modern desktop and systems support specialists.

Curriculum & Domain Focus

This test evaluates real-world knowledge aligned with CompTIA A+ 220-1101 and 220-1102 exam blueprints:

• Mobile Devices & Hardware Architecture: Laptop display replacement, memory form factors (SODIMM vs DIMM, DDR4 vs DDR5), power supply calculations (wattage, 12V rails), PCIe expansion lanes, NVMe M.2 thermal throttling, and peripheral interfaces (USB-C, Thunderbolt 4, DisplayPort).
• Networking & Virtualization: SOHO router setup, DHCP scope reservation, DNS configuration, client-side hypervisors (Type 1 bare-metal vs Type 2 hosted), virtual machine resource provisioning, and cloud service models (IaaS, PaaS, SaaS).
• Hardware & Network Troubleshooting: Resolving POST error beeps, BSOD crash dumps, thermal shutdowns, battery swelling, intermittent Wi-Fi connectivity, printer maintenance (laser drum, fuser, transfer rollers), and cable testing.
• Operating Systems & Administration: Windows administration (dism, sfc /scannow, diskpart, Event Viewer, Group Policy), macOS disk utility and terminal commands, Linux terminal navigation (ls, chmod, grep, ps), and automated OS deployment.
• Security & Operational Procedures: Antivirus remediation, malware isolation, physical access controls, data destruction standards (DoD 5220.22-M, degaussing), electrostatic discharge (ESD) safety, and ticketing communication standards.

Practical Troubleshooting Focus

The questions emphasize real helpdesk and field technician scenarios. You will diagnose intermittent boot failures, verify storage drive health via SMART attributes, isolate network adapter conflicts, and implement security controls on remote worker laptops.
