CompTIA A+ Core 2 Practice Test 2026 (220-1202)

Free Core 2 questions with every answer explained and linked to its source, from Windows commands and malware removal to backups and change management.

Up to 90 questions · 90 min · 700/900 to pass

How many questions are on CompTIA A+ Core 2, and what score passes?

CompTIA A+ Core 2 (220-1202) has a maximum of 90 questions in 90 minutes: multiple-choice (single and multiple response), drag-and-drop and performance-based questions. You pass with 700 on a scale of 100 to 900, higher than Core 1’s 675. To earn A+ you also pass Core 1 (220-1201), from the same V15 series. Operating systems and security are the largest domains at 28% each.

Anyone can take it: CompTIA sets no prerequisite and recommends about 12 months of hands-on work in an IT support role. You buy one exam voucher for each core, so A+ costs two exam fees. CompTIA publishes no pass rate. Once you pass both cores, A+ is valid for three years, and you can renew it with continuing education instead of retaking the exams.

USB-CThe exam

What does CompTIA A+ Core 2 (220-1202) cover?

Four domains, drawn as the strands of one cable, each as thick as its share of the exam in CompTIA’s Core 2 objectives.

The format

Up to 90 questions in 90 minutes, scored from 100 to 900: 700 passes Core 2. Offered in English, German and Japanese. CompTIA recommends 12 months of hands-on experience in an IT support specialist job role.

If you do not pass

No wait before a second attempt. Before a third or any later attempt, wait at least 14 calendar days. Every attempt is paid; CompTIA gives no free retakes (retake policy).

How long it lasts

A+ is valid for three years from the day you certify. You can renew with continuing education units instead of retaking the exam (renewal policy).

Malware removal steps and malware types

Objective 2.6 gives the removal steps in order, and questions ask what comes next. Learn the order, then the kinds of malware it is used on.

  1. 1Investigate and verify malware symptoms
  2. 2Quarantine the infected system
  3. 3Disable System Restore (Windows Home)
  4. 4Remediate infected systems
  5. 5Update anti-malware software
  6. 6Scan and remove (safe mode, preinstallation environment)
  7. 7Reimage or reinstall
  8. 8Schedule scans and run updates
  9. 9Enable System Restore and create a restore point (Windows Home)
  10. 10Educate the end user

The two System Restore steps exist because restore points can hold the malware and bring it back; you turn restore off before cleaning and back on, with a fresh point, after.

Malware types

Trojan
Looks useful, carries a hidden harmful function.
Rootkit
Hides itself and keeps privileged access, often below the OS.
Ransomware
Encrypts files and demands payment for the key.
Spyware
Collects what you do and sends it out without consent.
Keylogger
Records keystrokes, such as passwords.
Boot sector virus
Infects the boot record, so it loads before Windows.
Cryptominer
Uses your CPU or GPU to mine coins: slow, hot, loud.
Fileless
Runs in memory and through built-in tools, with no file on disk to scan.

Steps and types: 220-1202 objectives 2.4 and 2.6. Definitions: NIST glossary; ransomware response: CISA StopRansomware.

Windows, mobile and security symptoms, and the first check

Each question gives a symptom and asks for the likely cause or the next step. Objective 3.1 lists the Windows symptoms; 3.3 and 3.4 list the signs of a security problem.

Blue screen after a driver update
Roll back or remove the new driver; Microsoft says third-party drivers cause most stop errors. (Microsoft)
No OS found
Check the boot order and remove USB media, then repair startup from Windows RE.
Low memory warnings, slow PC
Task Manager, Processes: find what uses the memory and close or remove it.
Services not starting
Services console: startup type and dependencies; then Event Viewer for the error.
Time drift, sign-in fails on a domain
Resync the clock (w32tm /resync); Kerberos needs closely matched clocks.
Applications crashing
Event Viewer, Application log; then repair, update or reinstall the app.

A phone may be compromised when you see

  • Apps from unofficial stores
  • Developer mode or root/jailbreak
  • High network traffic, data-usage alerts
  • Fake security warnings
  • High number of ads
  • Leaked personal files

A PC may be compromised when you see

  • Cannot reach the network
  • Desktop alerts and false antivirus alerts
  • Missing or renamed files
  • Random pop-ups
  • Certificate warnings
  • Browser redirection

Symptom lists: 220-1202 objectives 3.1, 3.3 and 3.4.

DisplayPortOperational procedures 21%

Change management, backups and safety

The smallest domain, and the most procedural: questions ask which step is missing, which backup restores fastest, or what to do before you open a case.

A change, from request to sign-off

  1. RequestPurpose, scope, affected systems, date and time
  2. Risk analysisRisk level, change type (standard, normal, emergency)
  3. PlansRollback plan, backup plan, sandbox testing
  4. ApprovalChange board approves
  5. ImplementationInside the maintenance window, peer reviewed
  6. AcceptanceEnd users confirm it works

Backup types

Full
Copies everything. Slowest to run, simplest to restore.
Incremental
Only what changed since the last backup of any kind. Fastest to run; a restore needs the full plus every incremental.
Differential
Everything changed since the last full. A restore needs the full plus the latest differential.
Synthetic full
A new full built from the last full and later incrementals, without reading the source again.

The 3-2-1 rule: three copies, on two kinds of media, one of them off site (CISA). Grandfather-father-son rotates daily, weekly and monthly sets.

Safety before you open a case

  • ESD strap and mat
  • Equipment grounding
  • Disconnect power before repairing a PC
  • Lift with your legs
  • Fire safety
  • Safety goggles
  • Comply with government regulations

Change, backup and safety lists: 220-1202 objectives 4.2 to 4.4.

CompTIA A+ Core 2 FAQ

Format, passing score, what Core 2 covers, Core 1 and retakes.

A maximum of 90, in 90 minutes, per CompTIA's Core 2 (220-1202) exam objectives. They mix multiple-choice (single and multiple response), drag-and-drop and performance-based questions.

700 on a scale of 100 to 900, per CompTIA's Core 2 exam objectives. Core 1 (220-1201) needs 675. The scaled score is not a simple percentage of questions right.

Four domains in the 220-1202 objectives: operating systems (28%), security (28%), software troubleshooting (23%) and operational procedures (21%). Core 1 covers hardware, networking, mobile devices, virtualization and hardware troubleshooting instead.

Yes. CompTIA lets you take the two A+ exams in either order. What it does require is that Core 2 (220-1202) and Core 1 (220-1201) come from the same series (V15). If you already support users on Windows, macOS or Linux, Core 2 often feels more familiar to start with.

No. A Core 1 pass still counts while you retake Core 2, as long as both exams are from the V15 series. For Core 2 itself, CompTIA's retake policy allows a second try at once; a third or later try needs 14 calendar days since your last one, and each try is paid.

Here, with no signup: 40 free CompTIA A+ Core 2 practice questions, each with the correct answer, why the other options are wrong and the source it comes from. You can answer them one by one, read them all with answers on the questions page, or sit a timed mock exam of 40 questions that scores you in each exam area.

Yes. Open the exam simulator and sit a timed mock exam of 40 questions built from the free questions, once, with no signup. At the end you see where you stand in each exam area, so you know what to study next.

It splits the questions across the exam's areas using the weights CompTIA publishes, then picks questions inside each area, favoring ones you missed before and never repeating one within a run. A retake is a new draw, so you will meet different questions. It is a practice mock exam, not an official replica of the real exam.
