This CompTIA A+ Core 2 (220-1102) Practice Test: 1500 Certified Questions is built to train real-world support technicians who work every day with connectivity, routing decisions, switching behavior, cabling standards and IP-based services. Instead of short trivia, the questions are structured around realistic support scenarios, troubleshooting logic and configuration choices that mirror what you see in helpdesk and field environments.

This course contains 1,500 questions divided into six sections of 250 questions each, giving you repeated exposure to the core networking concepts that A+ technicians are expected to recognize, explain and fix under pressure.

You start with network architecture foundations, where you review common topologies, layered designs, wired and wireless segments, and how devices are placed logically and physically in a real environment. The next section focuses on switching behavior and VLAN-based segmentation, helping you understand how traffic moves at Layer 2, how broadcast domains are controlled and how misconfigured ports cause strange connectivity issues.

From there, the course moves into IP addressing, subnetting and routing logic, where you practice reading addresses, choosing masks, identifying gateways and mapping how packets move between subnets and networks. Another section is dedicated to cabling systems and media standards, covering copper types, fiber, termination practices, testing tools and typical physical layer faults that sit behind “no network” complaints.

You also work through wireless networking and access edge connectivity, including SSIDs, channels, interference, authentication options and how wireless links integrate with wired infrastructure. The final section brings everything together with network services, monitoring and resilience, connecting DHCP, DNS, VPNs, firewalls, logs and basic security controls into a coherent operational picture.

Each practice test can be retaken as many times as you like, making it easier to track progress and reinforce weak areas over time. Whether you are aiming to pass the CompTIA A+ Core 2 exam, preparing for your first IT support role or strengthening practical troubleshooting skills, this course helps you build structured, confidence-ready networking knowledge within the A+ scope.
