CompTIA Tech+
You do each task instead of picking an answer. Every question is explained after you check it, and you get a score at the end.

OpenpassAI’s practice sessions add performance-based questions, with command-line and network topology tasks, to full timed exams, AI explanations and a readiness score.
The questions
Each one with its scenario and task. Try it above first, then open the explanation.
Question 1 · Sorting · Tech Concepts and Terminology
Every computer takes data in, processes it, stores it and puts results out. A new colleague is setting up a shop counter and wants to know which job each device does.
Put each device under the job it does.
Input devices send data into the computer: what you type, say or scan. Output devices present results to a person: on a screen, on paper or as sound. Storage devices keep data after the power is switched off.
Question 2 · Matching · Infrastructure
You’re helping a friend choose parts for a desktop PC, and they want to know what each one is for.
Match each job to the component that does it.
The CPU carries out program instructions. RAM holds what is running right now and is emptied when the power goes off, while a solid-state drive keeps files without power. The network interface card connects the computer to a network, and the graphics processing unit draws what the monitor shows. The motherboard connects them all, and the power supply feeds them.
Question 3 · Matching · Applications and Software
An inventory of the software on a company laptop lists items by purpose, and you need to label each one.
Match each description to the kind of software it is.
The operating system manages the hardware, the files and the programs that run. A device driver is the small piece that lets the operating system use one particular device. A hypervisor creates and runs virtual machines. Anti-malware finds and removes malicious software. Open-source software comes with its source code, which anyone may study, change and share. Firmware is software built into a device’s own chips.
Question 4 · Sorting · Software Development Concepts
A developer is declaring variables for a customer record and must give each value the right data type.
Put each value under its data type.
An integer is a whole number, and a float has a fractional part. A Boolean has only two possible values, true and false. A string is text: any run of characters. A postal code is a string even when it is all digits, because nobody does arithmetic with it and a leading zero has to be kept.
Question 5 · Matching · Data and Database Fundamentals
A small business is moving its customer list from a spreadsheet into a relational database, and the consultant’s proposal is full of unfamiliar terms.
Match each description to the term it defines.
A table holds one kind of record in rows and columns. The primary key is the column whose value is different for every row, so each record can be found exactly. A foreign key holds another table’s primary key, which is how an order points to its customer. A query asks the database for data, and the schema is the structure itself: which tables exist and what their columns hold.
Question 6 · Sorting · Security
A security plan lists what the company already does. Your manager wants each measure filed under the goal it serves.
Put each measure under the security goal it protects.
Confidentiality keeps data from people who shouldn’t see it. Integrity makes sure data hasn’t been changed without anyone knowing. Availability keeps systems and data usable when they are needed.
CompTIA lists Tech+ among its certifications without performance-based questions, so the real exam is multiple choice. These tasks cover the same objectives hands-on, and they’re good preparation if A+ is your next step. CompTIA’s page on performance-based questions, read on November 12, 2026.
Guide
CompTIA describes performance-based questions as exam items that test your ability to solve problems in real-world settings. Most are simulations: an approximation of a tool such as a firewall, a network diagram, a terminal window or an operating system.
You don’t pick an answer. You do the task, and there can be more than one correct way to do it.
Try each question cold. Getting it wrong first and then reading why teaches more than reading the answer and nodding along.
A right answer reached by guessing is a wrong answer waiting for exam day. Every question here explains why each part is what it is.
CompTIA says a simulation question can be skipped and returned to later, with your work saved. If one is eating your time, move on, answer the multiple-choice questions and come back.
