Tech+ FC0-U71 Exam Objectives: All Six Domains Broken Down

The smart way to study any exam is to follow the weighting, not just your interests. CompTIA Tech+ FC0-U71 tells you exactly where the questions are, and this article walks through all six domains, what each one covers in plain language, and how to prioritize your time.

For exam mechanics, see the format guide. For the whole path, the complete Tech+ guide ties it together.

The weighting at a glance

Infrastructure and Security together are 43% of the exam. If you have limited study time, those two domains give you the biggest return.

Domain 1: IT Concepts and Terminology (13%)

This is the vocabulary domain — the language of IT that everything else builds on.

You'll cover the basics of how computers work (the input, processing, output, and storage cycle), notational systems like binary and hexadecimal, common units of measure for storage and speed, and CompTIA's troubleshooting methodology. None of it is deep, but it's the foundation, so don't skip it. Getting comfortable with binary and hex early makes several later topics much easier.

Domain 2: Infrastructure (24%)

The heaviest domain, and where a lot of a beginner's "aha" moments happen. This is the physical and networked world of technology.

Expect content on common computing devices and their purposes, internal components (CPU, RAM, motherboard), storage types, installing and configuring peripherals, input/output interfaces, and the basics of networking and cloud models. Because it's the largest domain, it deserves the most study time. If a term like "router" or "cloud model" feels fuzzy, this is where to slow down.

Domain 3: Applications and Software (18%)

This domain covers the software layer you interact with every day.

You'll learn the components and purpose of operating systems, the types and proper use of software, and how to configure common web browser features. FC0-U71 also brings in the common uses of artificial intelligence here — a modern addition that reflects how technology is changing. The framing stays conceptual: know what each thing is for and when you'd use it.

Domain 4: Software Development Concepts (13%)

Don't worry — you won't be asked to write code. This domain is about understanding development at a conceptual level.

It covers programming language categories, fundamental data types and their characteristics, the purpose of common programming concepts, and basic organizational and logic ideas. The goal is technology literacy: recognizing what a variable or a loop is and why developers use them, not building an application.

Domain 5: Database Fundamentals (13%)

Databases quietly power most of the software you use, and this domain explains why.

You'll explain the value of data and information, the purpose and concepts of a database, and compare different database structures and ways of interacting with them. Again, it's conceptual — understanding what a database does and why it matters, not administering one.

Domain 6: Security (19%)

The second-largest domain, and an increasingly important one for everyone in tech.

It covers fundamental security concepts including the CIA triad (confidentiality, integrity, availability), methods for securing devices, password best practices, common uses of encryption, configuring security on a small wireless network, and recognizing threats like phishing and malware. Even at a foundational level, this domain builds the security awareness that every IT role now expects.

How to sequence your study

A sensible order for beginners: start with IT Concepts and Terminology to learn the vocabulary, then invest heavily in Infrastructure as the largest domain, cover Applications and Software next, and work through Software Development, Database Fundamentals, and Security. Because Security is 19%, give it solid, dedicated time rather than treating it as an afterthought. The study plan lays this out week by week.

While Tech+ has no hands-on exam questions, a little practical experience makes abstract concepts stick — installing software, connecting a device, or exploring a browser's settings turns a definition into something you actually understand.

Make concepts click with hands-on practice: CompTIA Tech+ CertMaster Labs (FC0-U71) offers guided exercises that reinforce the objectives. To cover every domain in a structured course, pair it with CertMaster Learn. As an Authorized CompTIA Partner, these are the official versions.

FAQ

Which domain is most important? Infrastructure at 24%. It's the largest domain, so it deserves the most study time, with Security (19%) close behind.

Do I need to know how to code for Software Development Concepts? No. It's conceptual — you'll recognize programming ideas and terms, not write programs.

Is there hands-on content on the exam? No. All questions are multiple-choice. But a little hands-on practice while studying helps the concepts stick.

Why are Infrastructure and Security emphasized? Together they're 43% of the exam, reflecting how central hardware, networking, and security awareness are to any IT role.

Does Tech+ cover AI? Yes. FC0-U71 includes the common uses of artificial intelligence within the Applications and Software domain.
