CompTIA A+ Core Series: The Cert That Proves You Can Support Any Device, OS, or User

What IT hiring managers mean when they say “A+ required”

The A+ requirement in most entry-level IT job descriptions signals that the candidate can identify hardware components by sight, troubleshoot a non-booting system with a structured diagnostic process, install and configure a Windows workstation without assistance, and navigate a basic security policy. A+ is the standardised proof of that floor of competence. The DoD 8570.01-M mapping — now transitioning to DoD 8140 — means the credential is not just employer convention; it is a regulatory gate for federal government support roles and DoD contractor positions at the IAT Level I tier.

The exam does not test deep specialisation in any single area. It tests broad operational competence across the full hardware-to-software-to-security stack that a level-1 support technician needs to function on day one. Before A+, the only signal an employer had was interview performance and stated experience. After A+, they have a vendor-neutral baseline that holds across every hardware vendor, OS edition, and client environment.

Core 1 (220-1101) — Domain Breakdown

Five domains, 675/900 to pass, up to 90 questions in 90 minutes.

Core 2 (220-1102) — Domain Breakdown

Four domains, 700/900 to pass, up to 90 questions in 90 minutes.

PBQs (performance-based questions) load first in every A+ exam. CompTIA places them at the front deliberately — you cannot skip past them and return. Each PBQ simulates a real scenario: dragging components to build a compliant workstation, typing commands in a simulated terminal, or configuring settings in a virtual interface. They carry higher per-question weight than standard multiple choice. The most common failure mode is over-thinking: most PBQ scenarios have one clearly correct answer based on the domain knowledge, and candidates who spend too long second-guessing exhaust the time they need for the remaining questions.

Performance-based questions and exam strategy

Unlike standard multiple-choice items, PBQs cannot be guessed. A drag-and-drop asking you to assemble a workstation with specific RAM capacity in dual-channel configuration requires knowing what dual-channel means (two identical RAM sticks in the correct coloured slots) and how to calculate total capacity. A terminal PBQ asking you to identify why a host cannot reach the internet requires running the right commands in the right order: ipconfig to check the IP address and gateway, ping 127.0.0.1 to confirm the TCP/IP stack is functional, ping <gateway> to confirm local network connectivity, ping 8.8.8.8 to test internet routing, nslookup to separate DNS failures from routing failures.

Time allocation: with 90 questions in 90 minutes, the average target is one minute per question. PBQs typically take 3–6 minutes each. Work through PBQs methodically, commit to answers, and bank time for the multiple-choice section. Flag questions you are genuinely unsure about and return to them — unlike PBQs, standard multiple-choice can be revisited within the exam session.

A+ in the certification landscape

A+ is not a prerequisite for any other CompTIA exam — Network+, Security+, and Linux+ can all be attempted without it. In practice, the Core 1 networking domain provides direct overlap with Network+ concepts, and the Core 2 security domain covers vocabulary that Security+ then deepens significantly. Candidates who pass both A+ exams typically find Network+ (N10-009) achievable within 60–90 additional days of study, and Security+ (SY0-701) achievable within 90–120 days after A+.

The DoD 8570 framework positions A+ as IAT Level I alongside Network+ — holding either satisfies the Level I baseline requirement. For US federal government and DoD contractor roles, A+ is therefore a literal employment prerequisite, not just a hiring preference. For non-government roles, A+ signals an employer that a candidate can be deployed immediately into a Tier 1 support environment with minimal onboarding overhead — reducing hiring risk rather than adding premium skills.

For career trajectory: help desk and desktop technician roles with A+ certification pay 10–15% above non-certified candidates in equivalent roles according to CompTIA salary survey data. The certification does not gate access to senior roles — for that, the pathway runs through Network+, Security+, and then vendor-specific certs (AWS, Azure, Cisco) or advanced CompTIA credentials (CySA+, CASP+). A+ is the foundation, not the ceiling.
