Click Study Flashcards above to open the flashcard hub — hundreds of CompTIA A+ cards you can flip, match, type, or quiz yourself on. Every card is drawn from the nine official domains across Core 1 (220-1201) and Core 2 (220-1202), so you study exactly what the exams test.[1] Pair them with our free practice test and study guide.

CompTIA A+ is one of the 14 CompTIA certifications — explore our CompTIA flashcards to compare and prep across the whole family.

CompTIA A+ Flashcard Study Modes

Flip mode gives you a first read of each card, then Match turns terms and definitions into a timed pairing game, Type asks you to read a definition and produce the term — S.M.A.R.T. errors, for instance — and Quiz rebuilds the same cards as multiple choice so you can check recall under pressure before moving on.

Why Flashcards Work for the CompTIA A+

Hardware (Core 1) is the largest block at 51 cards, drilling component vocabulary, storage arrangements, and boot behavior. You get short acronym cards such as TPM and POST, expansion and connector terms like PCIe and eSATA, and array cards that force you to separate RAID 0 from RAID 1 and RAID 5. Networking (Core 1) follows with 49 cards on protocols, wireless settings, and the port numbers that show up constantly, including Port 22 and Port 445, alongside terms like VLAN and WPA3.

Operating Systems (Core 2) carries 46 cards built around Windows utilities, command-line tools, and disk concepts. Expect prompts such as MSConfig, Event Viewer, and ipconfig, plus comparison cards like MBR vs GPT and recovery topics such as Safe Mode. Security (Core 2) adds 45 cards of threat and control vocabulary, mixing attack terms like Phishing and Zero-day with protective concepts such as the CIA triad, DLP, and Biometrics.

Software Troubleshooting & Operational Procedures (Core 2) holds 33 cards covering documentation, safety, and support process. These are the cards that ask you to define AUP, explain the 3-2-1 backup rule, and separate a Surge protector vs UPS, with safety items like Electrical safety: ESD and SDS / MSDS in the same set.

Mobile, Virtualization & Cloud (Core 1) contributes 30 cards on mobile hardware and service models, including Digitizer, eSIM, MDM, and Cloud model: IaaS. Hardware & Network Troubleshooting (Core 1) rounds out the deck with another 30 cards that pair symptoms with tools, from No video output and Overheating symptoms to command cards like ping and nslookup / dig.

The A+ is dense with discrete facts — well-known ports, protocols, connectors, RAID levels, Windows commands, malware types, and acronyms.[2] Spaced flashcards are the most efficient way to keep it all fresh. Used alongside our practice test and study guide, they turn review time into measurable progress.

CompTIA A+ Flashcards by Domain

The cards are organized by the nine official domains across both cores. Drill the highest-weighted ones first — in Core 1 that’s Troubleshooting, Hardware, and Networking; in Core 2, Operating Systems and Security tie for the lead:[1]

How to Get the Most Out of These Flashcards

  • Start with Hardware (Core 1). At 51 cards it is the biggest domain here, and its component and RAID vocabulary underpins the troubleshooting cards you will meet later.
  • Type-drill the exact strings. Cards like Port 53 and ipconfig / ifconfig punish vague recall, so typing them forces the precision the exam expects from command and port answers.
  • Use Match for acronyms. Short fronts such as TPM, DMZ, and VDI pair quickly, which makes the timed game an efficient way to clear Hardware and Networking clutter.
  • Move to the practice test when Quiz holds. Once multiple choice on Security (Core 2) and Operating Systems (Core 2) feels routine, switch to full-length questions and the study guide for weak spots.
  • Keep the cadence small. With 284 cards, work one domain per session, re-Flip yesterday’s misses first, and rotate the 30-card Core 1 sets in as review rather than new material.
