A support request can ask for a fault to be inspected, a repair to be made, or recovery to be proved. A command that suits one task may be wrong for another. Checking Windows system files without altering them is different from attempting a repair, just as seeing a successful backup job is different from restoring usable data.
CompTIA A+ Core 2 covers the software knowledge and support judgment behind these decisions. Its four domains are Operating Systems, Security, Software Troubleshooting, and Operational Procedures. The subject connects work on Windows, macOS, Linux, and mobile devices with access control, diagnostic evidence, change approval, and communication with users.
- Operating system and filesystem
- An operating system (OS) runs applications and manages the device. A filesystem organizes stored files. Storage compatibility and OS troubleshooting are related, but changing a disk's format is not the same as repairing an application.
- Authentication and permissions
- Authentication establishes identity. Permissions determine what that identity may do, such as read a document, change it, or run a program. A successful sign-in does not mean unrestricted access is appropriate.
Platform requirements can change the best answer even when the hardware looks similar. A removable drive shared between Windows and macOS may need a compatibility format such as ExFAT. A Mac-only data volume can instead use Apple File System (APFS) and its Mac-specific features. Formatting erases existing contents, so choosing a suitable format does not remove the need to protect the data already on the drive.
Security questions often turn on how much access is needed and for how long. A contractor who only needs to read one project's documents for a week does not need permanent administrator rights. This is the principle of least privilege. It also explains why an approved installation can use administrative elevation while ordinary daily work remains under a standard account.
Diagnostic evidence matters just as much as terminology. An explicit insufficient-storage error points toward checking and reclaiming storage through an approved process. Intrusive advertisements appearing after an unapproved app was installed make that app a useful lead, but timing alone does not prove the cause. Changing unrelated settings or resetting the device before investigating can miss the stated problem.
Operational procedures make support work recoverable and understandable to the next technician. A rollback plan sets out how to return from a failed change. A useful ticket preserves symptoms, attempted steps, and their results without recording passwords. Backup testing checks whether data can actually be restored. These are practical parts of the technical task, not paperwork that begins only after a repair.
For A+ V15, certification requires passing both Core 1 (220-1201) and Core 2 (220-1202). The Core 2 objectives document specifies up to 90 questions in 90 minutes, including multiple-choice and performance-based questions, and recommends 12 months of hands-on IT support experience. Recognizing a correct answer is useful preparation, but it does not by itself demonstrate safe task execution or award a certification.
How to Use This Tool:
The practice bank contains 32 independently authored English questions dated September 11, 2026, targeting 220-1202 V15 objectives document 4.0. This is unofficial practice, not affiliated with or endorsed by CompTIA.
- Choose a Domain / practice focus and Question count. The initial setup is five questions from all domains. That focus offers 1, 5, 8, 16, or 32 questions; narrower focuses have their own count menus. Changing focus automatically replaces a count that is no longer allowed. If starting is disabled, select an available focus, feedback mode, and count.
- Choose Feedback timing. Learn — feedback after each answer shows the correction and explanation immediately. Review — feedback at completion records the answer without revealing correctness until results. Neither mode has a timer.
- Enter an optional Replay seed under Advanced when you need a repeatable round. Leaving it blank uses a stable default, not a fresh random draw. The result's Active replay seed identifies the actual round and is separate from the text left in the setup field.
- Select Start exam practice, read the requirement, and choose one of four answers. Continue with Next question after each recorded answer.
Selecting an answer records and locks it immediately. There is no skip or answer-edit step. End round clears the attempt and returns to setup; it does not submit a partial result.
- Select View results once every question has an answer. Read the missed-answer explanations and use the Answer ledger to revisit correct answers that were guesses. Retry missed starts a round containing only incorrect items; Replay same seed repeats the active round, while Try a new seed starts another seeded round.
Interpreting Results:
The completed headline is the number correct divided by the number of questions in that round. During practice, the answered count and progress bar measure completion, not correctness. Finishing every question can produce 100% progress even when several answers are wrong.
Domain performance compares correct and missed answer counts for the domains sampled. A domain absent from the chart was not tested in that round. A small number of correct answers cannot establish broad proficiency, and raw counts from differently sized domain samples should not be treated as a ranking of ability.
Use Missed answer review to identify the specific distinction that was missed, then read its source before retrying. Some links establish the objective's scope; others document a command or technical behavior. Those references support study without making the question official. The full ledger also lets you review the reasoning behind a correct selection.
Perfect round means no incorrect answers in this particular sample. There is no practice pass threshold, calibrated readiness band, or prediction of a CompTIA result. A useful follow-up is to explain the answer without looking at the choices, check the corresponding official objective, and practice the task in an appropriate authorized environment.
If the domain chart is unavailable, use Retry chart. The answer ledger remains available, and the domain-performance CSV can provide the counts without a rendered chart.
Technical Details:
Single-choice scoring checks whether the selected answer matches the designated answer for the stated scenario. Each item carries the same point value. Domain, platform, question order, and feedback timing do not add score multipliers or partial credit.
Points, accuracy and completion
A correct answer earns one point and an incorrect answer earns zero. Total points therefore equal the correct count, while possible points equal all questions in the round. The corresponding raw accuracy percentage is:
Here, P is raw accuracy in percent, C is the correct-answer count, and N is the round's question count. The visible score headline keeps the exact C/N counts rather than reporting an official scaled score.
Progress uses the number of recorded answers instead of the number correct:
G is progress in percent and A is the answered count. Unanswered items remain in N but are not marked incorrect. Incorrect answers number A minus C, and unanswered questions number N minus A. Raw accuracy is retained without rounding. Counts are exact integers; the displayed progress percentage is rounded to the nearest whole percent, with half-percent ties rounded up.
For example, three correct answers among five recorded answers in an eight-question round give 37.5% raw accuracy and 62.5% progress, displayed as 63% progress. There are two incorrect answers and three unanswered questions. This is still an unfinished round, not a 3/5 final score.
| Round condition | Exact rule | Meaning |
|---|---|---|
| Unfinished | A < N | Results are not complete. Unanswered items are not misses. |
| Completed with misses | A = N and C < N | At least one answer needs review. |
| Completed without misses | A = C = N | Perfect round for the selected items only. |
The reference exam lists a passing score of 700 on a scale of 100 to 900. That is a different score system. Dividing 700 by 900 does not establish a practice pass percentage, and no conversion from these practice points to that scale is provided.
Official domain emphasis and practice coverage
The official percentages describe the examination blueprint. The practice bank has eight questions in each domain, with selected concepts rather than exhaustive objective coverage.
| Domain | Official weight | Practice items | Selected practice concepts |
|---|---|---|---|
| Operating Systems | 28% | 8 | Filesystems, permissions, command-line reports, and Mac backups. |
| Security | 28% | 8 | Access scope, authentication, patching, containment, and connection trust. |
| Software Troubleshooting | 23% | 8 | Targeted Windows checks, mobile symptoms, suspicious software, and logs. |
| Operational Procedures | 21% | 8 | Rollback, tickets, restore testing, evidence handling, consent, and data privacy. |
Selection is uniform without replacement within the chosen focus. A question cannot appear twice in one round, but a short all-domain round need not include every domain. Taking all 32 gives each domain 25% of the questions, not its official blueprint weight. The official percentages are neither selection quotas nor practice-score multipliers.
Platform focuses regroup the same bank into Windows with 10 items, macOS with 3, Linux with 2, Mobile with 4, and Cross-platform procedures/security with 13. Concept checks contains 6 items and Applied scenarios contains 26. These are alternative selections from the same 32 questions, not additional banks. The concept and scenario labels are author-assigned distinctions, not calibrated levels of exam difficulty.
Inspection, repair, and permission scope
Technical answers depend on both the object being checked and the permitted action. System File Checker (SFC) concerns protected Windows system files. CHKDSK concerns a volume's filesystem. The Domain Name System (DNS) resolver cache is local name-resolution data, not the adapter's leased network address.
| Command | Specific operation | Important boundary |
|---|---|---|
sfc /verifyonly |
Checks the integrity of protected system files. | Does not attempt repairs. |
sfc /scannow |
Checks protected system files and attempts repairs where possible. | Exceeds an inspection-only instruction. |
chkdsk D: /f |
Requests fixes for filesystem errors on local drive D:. | Requires the volume to be locked; checking after a restart may be necessary. |
ipconfig /all |
Displays the full network configuration for all adapters. | Does not release the adapters' leased addresses. |
ipconfig /flushdns |
Clears and resets the local DNS resolver cache. | Does not perform the address-release operation. |
For Linux permissions, chmod u+x check.sh adds execute permission for the owner while retaining existing permissions. The u selects the owner and + adds the named permission. By comparison, a+x grants execute permission to all three user classes, while u=x replaces the owner's existing permissions with execute alone. A requirement to preserve access settings makes those differences decisive.
The filesystem-repair scenario explicitly assumes approval and a verified backup. Recognizing the command is not an instruction to run it on an unassessed device. SFC also does not prove that every cause of instability has been resolved. Selecting any command as a practice answer does not execute it or inspect the computer.
Repeatability and comparison limits
Reproducing a round requires the same seed, focus, feedback mode, question count, question-bank version, and any missed-item restriction. Feedback mode affects the shuffle, so switching between Learn and Review can change the questions even when the seed text stays the same. The four authored answer choices are also reordered reproducibly.
Surrounding spaces are removed from seed text. Longer entries are shortened at a whole character to fit the allowance of 128 basic text characters; many emoji use two places. Different long entries can therefore reproduce the same round.
A new seed can reuse questions from earlier attempts. When the entire available focus is selected, a new seed cannot introduce questions outside that focus. Same-seed repetition and missed-only retries are useful for reinforcement, but improved scores on familiar items are not independent evidence of broader readiness.
The practice is untimed and provides no multiple-response, drag-and-drop, or performance-based tasks. It does not measure hands-on execution or time management. Its dated question bank does not check live exam sales, language availability, regional scheduling, or retirement announcements. Confirm those details and the matching A+ exam version with CompTIA before booking.
Privacy Notes:
Answers are scored in the browser, but the saved address contains replay details and recorded responses in encoded, not encrypted, form. Someone with a compatible attempt link can restore those responses. The address can remain in browser history and reach the site when it is loaded. Avoid putting names, passwords, or customer information in a replay seed, and treat a shared attempt as disclosure of its answers.
A saved address can restore the round and recorded selections, but answered questions remain locked. End round clears the current attempt and its address state; it does not revoke copies of links already shared. Page resources, chart or document features, and opened reference links can use the network. Exported answer ledgers include the selected responses.
If Saved attempt unavailable appears, the link could be invalid or incompatible with the current question bank or saved-attempt format. Choose a supported setup and start a new round. If a warning instead says the attempt could not be saved in the URL, the saved URL information is cleared, while progress remains in the open page and reloading loses it. To try saving a new attempt, choose End round and start again with a different seed.
Worked Examples:
A repair command in an inspection-only question
Select Windows (10 items), a question count of 10, and Learn feedback. Suppose the protected-file inspection question is answered with sfc /scannow instead of sfc /verifyonly, while the other nine answers are correct. The completed headline is 9/10, equivalent to 90% raw accuracy. Operating Systems has two correct answers and one miss, Security has two correct answers, and Software Troubleshooting has five correct answers. Operational Procedures is absent because it was not sampled. The missed explanation identifies the important restriction: the approved task was verification without repairs.
A perfect retry has a smaller denominator
An eight-question Operational Procedures round finishes at 5/8 after mistakes on rollback planning, backup testing, and handling customer identifiers before using an artificial intelligence (AI) assistant. Choose Retry missed and the next round contains those three questions, even though three is not a normal setup count for that domain. Answering all three correctly produces 3/3 and Perfect round. It shows successful repetition of those missed items, not a corrected 8/8 result for the earlier round or proof that every operational procedure is understood.
