This CompTIA CIOS Practice Test 2-in-1: 1500 Certified Questions combines the core ideas of CompTIA A and CompTIA Network into one structured practice course. The questions are written around real support and operations scenarios, so you can see how hardware issues, OS problems, connectivity faults and basic security concerns appear in daily IT work.

The course contains 1,500 questions divided into six sections of 250 questions each. In the first section, Endpoint Hardware, Peripherals & Client Device Foundations — 250 Questions, you practise with desktops, laptops, components, peripherals and failure symptoms, building confidence in core A hardware skills.

The second section, Operating System Basics, User Support & Troubleshooting Workflows — 250 Questions, develops client OS and helpdesk skills, including installation, updates, drivers, user profiles and common ticket types such as slow systems, login issues and printing problems.

In the third section, Networking Essentials, Addressing & Small Office Connectivity — 250 Questions, you work through Network style fundamentals. You review IP addressing, DNS, DHCP, ports and basic protocols, and apply them to small office connectivity and everyday network incidents.

The fourth section, Network Infrastructure, Topologies & Wired/Wireless Implementation — 250 Questions, moves deeper into switches, routers, cabling, access points, VLAN concepts and Wi-Fi planning, helping you understand how infrastructure pieces fit together in real environments.

The fifth section, Security Fundamentals for Endpoints, Users & Network Access — 250 Questions, brings in practical security basics. You explore password hygiene, endpoint protection, Wi-Fi security modes, user behaviour risks and simple access control, all from an operational point of view.

Finally, the sixth section, IT Operations, Documentation, Monitoring & Cross-Domain Troubleshooting — 250 Questions, connects everything into operations-ready skills, focusing on ticket handling, documentation, SLAs, escalation and multi-symptom troubleshooting across hardware, OS, network and security.

Each practice test can be retaken as many times as you need, helping you track and enhance your progress, strengthen weaker areas and build structured confidence. Whether you are preparing for A and Network style objectives or working in real IT support and operations, this course gives you a clear, section-based path to practical, job-ready troubleshooting skills.
