Most candidates understand CompTIA Tech+ concepts — and still fail. This exam tests how you apply knowledge under pressure.

Tech+ Domain Coverage

CompTIA Tech+ (FC0-U61) tests broad IT literacy across six domains. Questions test conceptual understanding rather than deep technical implementation. The exam targets business professionals, help desk staff, and career changers.

  1. 01
    IT Concepts & Terminology — Hardware, software, networking, cloud, security basics
  2. 02
    Infrastructure — Desktop, mobile, network, cloud, and data center concepts
  3. 03
    Applications & Software — App types, software development lifecycle, databases
  4. 04
    Software Development Concepts — Development methodologies, version control basics
  5. 05
    Database Fundamentals — Database types, SQL basics, data management concepts
  6. 06
    Security — Threats, vulnerabilities, and basic security practices

Wrong instinct vs correct approach

A business wants to move applications to cloud with maximum control over the infrastructure
✕ Wrong instinct

Recommend SaaS for maximum flexibility

✓ Correct approach

SaaS provides minimum infrastructure control. IaaS provides maximum control over the OS and above while the provider manages hardware. If the organization needs full infrastructure control, recommend Private Cloud or IaaS.

A small business needs a database for storing customer data with flexible fields
✕ Wrong instinct

Always use a relational database for business data

✓ Correct approach

A document-oriented NoSQL database handles flexible schemas well — if customer records have varying fields, the rigid schema of relational databases creates maintenance overhead

An employee receives an email from IT asking them to reset their password via a link
✕ Wrong instinct

This is a legitimate IT request since it came from the IT domain

✓ Correct approach

This is a phishing attack — verify requests through a separate, known-good communication channel before clicking links or providing credentials

Know these cold

  • IaaS = most control; SaaS = least control; PaaS = in between
  • Cloud models — ublic (shared), Private (dedicated), Hybrid, Community
  • SDLC — lanning → Analysis → Design → Development → Testing → Deployment → Maintenance
  • Relational = structured tables + SQL; NoSQL = flexible schema for unstructured/semi-structured data
  • Phishing = malicious email; vishing = malicious voice call; smishing = malicious SMS
  • Ransomware encrypts data; worms self-replicate; spyware monitors — know each type's behavior
  • Backup 3-2-1 rule — copies, 2 different media types, 1 offsite

Can you answer these without checking your notes?

Common Exam Mistakes — What candidates get wrong

Over-preparing on technical depth instead of breadth

Tech+ tests conceptual literacy — not implementation expertise. Candidates who deep-dive on networking protocols miss the breadth of topics they haven't covered. Study all six domains at concept level.

Confusing public, private, and hybrid cloud models

Public cloud: shared infrastructure managed by provider. Private cloud: dedicated infrastructure. Hybrid cloud: combination. Community cloud: shared by organizations with common requirements. These distinctions appear in multiple scenario questions.

Misidentifying software development lifecycle phases

SDLC phases: Planning, Analysis, Design, Development, Testing, Deployment, Maintenance. Candidates who can't place activities in the correct phase miss SDLC sequencing questions.

Confusing relational and non-relational databases

Relational databases use structured tables with defined schemas and SQL. Non-relational (NoSQL) use flexible schemas with document, key-value, column, or graph models. The use case distinction is tested.

Misidentifying common security threat types

Ransomware encrypts data for payment. Worms self-replicate without human action. Spyware monitors without knowledge. These distinctions are tested in scenario questions.

Tech+ rewards broad IT literacy. Test whether you have solid foundational knowledge across all topic areas.
