CompTIA publishes exactly what the FC0-U71 tests and how much each part is worth. Here it is — every domain, its weight, the topics inside it, and the lessons that cover them.
Computing basics (input, processing, output, storage), binary/hexadecimal/decimal/octal, units of storage, speed and throughput, and the CompTIA troubleshooting methodology.
Computing devices and internal components, storage types, installing and configuring peripherals, input/output interfaces, virtualization and cloud models, internet service types, networking basics and small wireless networks.
Operating system components and purposes, software types and proper use, web browser features and configuration, and common uses of artificial intelligence.
Programming language categories, data types, programming concepts such as variables, arrays and functions, and organizational techniques and logic such as pseudocode, flowcharts, branching and looping.
The value of data, database concepts and purposes, relational vs non-relational structures, and basic data backup concepts.
The CIA triad and security frameworks, securing devices, password best practices, common encryption use cases, and securing a small wireless network.
Reading every note front to back is the slowest way to pass. The exam is weighted, so your revision should be too — the blueprint above tells you exactly where the marks are.
Infrastructure carries the most marks on the FC0-U71, so it earns the most of your attention. Work down the blueprint from the heaviest domain to the lightest rather than starting at domain 1 and grinding forward.
Read each lesson once without stopping to memorise — you are building a map, not a memory. On the second pass, read only the "what's tested" and key-takeaway blocks. If a takeaway surprises you, that lesson goes back on the pile.
Cover a lesson's key takeaways and try to say them out loud from the heading alone. Recall you can produce under your own steam is the only recall that survives a timed exam; recognition on a re-read is not the same thing.
Finishing the notes is not the goal — scoring is. Move to FC0-U71 practice questions early, then come back to the exact lessons your wrong answers point at. That loop is worth far more than a third read-through.
Exam structure, domain weights and scoring on this page come from the official FC0-U71 exam guide.
