Why People Fail the CompTIA Security+ Exam (And How to Avoid It)

Security+ is broad, vendor-neutral, and tied to real exam constraints. The current CompTIA exam is SY0-701. It costs $425, allows maximum of 90 questions in 90 minutes, and requires 750 on a scale of 100-900 to pass.

Why do people fail Security+?

The first mistake is treating every domain as equally weighted. On SY0-701, Security Operations is more than twice the size of General Security Concepts, so a study plan that splits time evenly is mathematically misaligned with the exam.

The second mistake is memorizing terms without attaching them to a use case. Knowing that SSH is port 22 matters less than recognizing that a blocked 22 explains why secure Linux administration fails while HTTPS on 443 still works.

The third mistake is mixing up control categories. When a question asks for the next step after identification, the answer lives in containment or eradication, not in a later lessons-learned meeting.

A fourth error is using outdated exam assumptions from SY0-601 forums or old YouTube playlists without checking the SY0-701 objectives. CompTIA's current outline gives more explicit room to cloud security, zero trust, automation, and modern operational defense.

The five domain weights on SY0-701

CompTIA's official Security+ page lists these five SY0-701 domains and weights: General Security Concepts — 12%; Threats, Vulnerabilities, and Mitigations — 22%; Security Architecture — 18%; Security Operations — 28%; Security Program Management and Oversight — 20%. A strong study plan mirrors these weights rather than dividing time evenly.

What to do instead

Treat Security+ as a weighted, scenario-driven exam. Memorize the constants: SY0-701, $425, up to 90 questions, 90 minutes, 750 passing score, PBQs near the beginning, and the five domain weights.
