CompTIA A+ 220-1201 & 220-1202 Flashcards: Core 1 and Core 2

Review the current V15 knowledge behind both CompTIA A+ exams in one 520-card package: 270 cards for Core 1 and 250 for Core 2. The deck covers mobile devices, networking, hardware, virtualization, cloud concepts, operating systems, security, commands, software support, operational procedures, and troubleshooting.

What the cards practice

The cards connect technologies, components, protocols, commands, and common acronyms with their purposes and key behavior. Separate retrieval prompts also work in the useful opposite direction: a technician task or requirement points to the right tool, setting, command, connector, or protocol. Short support scenarios ask for a likely cause, the first useful check, or the next corrective action. Ordered workflows are practiced only when the order matters on the job.

The deck does not mechanically reverse every fact or turn every source bullet into a card. It leaves out low-value acronym production, giant list prompts, unstable click paths, advanced material beyond the V15 entry-level boundary, and near-duplicate wording made only to increase the count.

Learning order

Core 1 starts with mobile hardware and connections, then builds through networking, physical hardware, virtualization, and cloud concepts before applying them to hardware and network troubleshooting. Core 2 moves from operating-system foundations into tools, commands, configuration, security, software troubleshooting, and day-to-day support operations. Inside each topic, recognition comes before selection and short diagnosis. Related forward and reverse cards are kept apart so one prompt does not give away the next.

Labs and PBQs

Flashcards are useful for recall and compact scenario decisions. They do not reproduce hands-on labs, performance-based questions, live command output, or the pressure and ambiguity of the certification exams. Use a real machine, lab environment, and lawful practice tests alongside this deck for installation, configuration, repair, and PBQ-style work.

Scope, provenance, and reuse

The live CompTIA Core 1 and Core 2 V15 pages and the current version 4.0 objective PDFs were reviewed on September 1, 2026. Both PDFs were last modified on November 25, 2025. They were used only to check the exam version, domain boundaries, weighting, and technical scope. Common technical facts are explained in original language and organized for retrieval practice. Public overview pages from three study tools were compared only for structure and learner expectations; their cards, questions, examples, explanations, and course text were not drafting input.

The Common knowledge · CC0 1.0 label applies to the deck’s original prompts, answers, organization, metadata, and generated cover to the extent applicable rights exist. It does not claim ownership of technical facts, CompTIA names, or third-party source material.

This deck is independently authored and unofficial. It is not affiliated with, endorsed by, or sponsored by CompTIA, Inc., and it uses no CompTIA logo or official trade dress.

No CompTIA exam questions, answers, performance-based questions, mark schemes, or objective wording were copied.

Current official requirements: Core 1 V15 (220-1201), Core 1 objectives PDF, Core 2 V15 (220-1202), and Core 2 objectives PDF.

    What sequence pairs a Bluetooth accessory safely?

    Atbilde

    Enable Bluetooth, put the accessory in pairing mode, select the intended device, confirm any PIN or code, and test the connection.

  25. 25. kartīte

    Jautājums

    How do GPS and cellular location services complement each other?

    Atbilde

    GPS derives position from satellites, while cellular and nearby-network data can speed or assist location. App permission and device settings control access.

  26. 26. kartīte

    Jautājums

    Which radios should you check when a phone has neither local Wi-Fi nor wide-area data?

    Atbilde

    Check Wi-Fi and cellular data separately, along with airplane mode. One radio can be disabled while the other remains available.

  27. 27. kartīte

    Jautājums

    What should you verify when adding mail to a mobile device?

    Atbilde

    Verify the account, credentials, incoming and outgoing server settings, security method, and network access. A correct password can't repair a wrong server setting.

  28. 28. kartīte

    Jautājums

    A phone can browse on Wi-Fi but not through its hotspot. What should you check?

    Atbilde

    Check that hotspot service is enabled, cellular data works, the plan permits tethering, and the client has the correct hotspot password.

  29. 29. kartīte

    Jautājums

    How should you test a newly configured mobile connection?

    Atbilde

    Test the intended path and service: join the correct network or carrier, verify addressing or signal, then open the required app or destination.

  30. 30. kartīte

    Central enrollment, device configuration, policy enforcement, corporate-app deployment, inventory, and approved remote actions.

  31. 31. kartīte

    Jautājums

    How do corporate-owned and BYOD management profiles usually differ?

    Atbilde

    Corporate-owned devices normally allow broader organizational control; BYOD profiles should isolate managed work data and respect the user's personal data under policy.

  32. 32. kartīte

    Jautājums

    What should be checked when calendar, contacts, or business mail stops synchronizing?

    Atbilde

    Check connectivity, account sign-in, sync scope, device time, storage, and service status before removing the account.

  33. 33. kartīte

    Jautājums

    Why do data caps matter to mobile synchronization?

    Atbilde

    Large mail, cloud-storage, or app sync jobs can consume metered cellular data. Choose what syncs and whether Wi-Fi is required.

  34. 34. kartīte

    Jautājums

    When is an MDM remote wipe appropriate?

    Atbilde

    When policy authorizes removal of protected data from a lost, stolen, retired, or reassigned device. Confirm the exact device and wipe scope first.

  35. 35. kartīte

    Jautājums

    What is the point of separating corporate apps and data on a personal phone?

    Atbilde

    It lets the organization enforce work controls and remove managed data without treating the user's whole device as corporate property.

  36. 36. kartīte

    Jautājums

    TCP provides connection-oriented, ordered, acknowledged delivery; UDP sends low-overhead datagrams without built-in ordering or retransmission.

  37. 37. kartīte

    Jautājums

    Which ports are associated with classic FTP?

    Port 53: usually UDP for ordinary queries and TCP when the response or operation requires it.

  41. 41. kartīte

    Jautājums

    Which ports carry DHCP client and server traffic?

  43. 43. kartīte

    Jautājums

    Which default port does POP3 use without TLS?

    Atbilde

    TCP 110. POP3 commonly downloads messages rather than synchronizing server-side folders like IMAP.

  44. 44. kartīte

    Jautājums

  55. 55. kartīte

    Jautājums

    What should guide Wi-Fi channel selection?

    Atbilde

    Local regulations, a spectrum or Wi-Fi survey, channel width, band support, interference, and neighboring use. Choose from measured conditions, then retest where users work.

  56. 56. kartīte

    What does a 169.254.x.x IPv4 address usually indicate?

    Atbilde

    APIPA self-assignment after the host failed to obtain DHCP configuration. Check the link and path to DHCP.

  85. 85. kartīte

    Jautājums

    When should a SOHO device use static rather than dynamic IP configuration?

    Atbilde

    Use static or reserved addressing when a predictable endpoint is required; use DHCP for ordinary clients that can accept leased settings.

  86. 86. kartīte

    Jautājums

    Jautājums

    How does IPv6 addressing differ from IPv4 addressing?

    Atbilde

    IPv6 uses 128-bit hexadecimal addresses; IPv4 uses 32-bit dotted-decimal addresses. Both still require correct local and routing configuration.

  88. 88. kartīte
