Exam-Focused Technical Guides

Study the Technical Models Behind Cloud, IT, Data, and Platform Certification Exams

Tech Exam Lexicon publishes technical study guides organized around live cloud, IT, security, programming, DevOps, data, and platform vendor sections, plus role-based career-path pages. The site stays guide-first: practical explanations, realistic distinctions, troubleshooting logic, and high-yield review pages that help you understand why an answer is right instead of memorizing a glossary.

Sixteen Vendor Sections Are Live

The current repo publishes sixteen vendor-first guide sections and role-first path pages. Beyond the earlier AWS, Azure, Google Cloud, CompTIA, Confluent, and Databricks families, the live tree now also includes Microsoft, Linux Foundation/CNCF, Python Institute, GitHub, HashiCorp, ISC2, Red Hat, Cisco, Oracle, and SnowPro. Most current exam guides follow the same pattern: guide overview, then cheat sheets, FAQs, glossaries, study plans, and resource pages.

How The Current Site Is Shaped

The content model is vendor-first for exam guides and role-first for career paths.

  • AWS, Azure, Microsoft, Google Cloud, CompTIA, Linux Foundation/CNCF, Python Institute, GitHub, Confluent, Databricks, HashiCorp, ISC2, Red Hat, Cisco, Oracle, and SnowPro all have published exam guides.
  • Career paths connect the live exam sections to help-desk and cloud-architect progression.
  • New families should appear here only after they are in the repo and ready to browse.
Step 1

Learn the Model

Start with the exam overview and the main guide page that matches your target certification. Focus on concepts, boundaries, and the troubleshooting logic the exam is actually testing.

Step 2

Drill Weak Spots

Use cheat sheets for fast recall, FAQs for distinctions and common traps, and resource pages when you need the official objectives, vendor docs, or a safe home-lab reference.

Step 3

Then Add Timed Practice

Once the explanation layer makes sense, move into timed practice to test pacing, recall speed, and scenario judgment under pressure.

Coverage Shape

The Published Site Spans Sixteen Vendor Hubs and Two Role Paths

The current site is not just a CompTIA or AWS shell. It now spans AWS, Azure, Microsoft, Google Cloud, CompTIA, Linux Foundation/CNCF, Python Institute, GitHub, Confluent, Databricks, HashiCorp, ISC2, Red Hat, Cisco, Oracle, and SnowPro, plus role-first pages that route readers by target job family instead of by vendor.

  • Vendor hubs: AWS, Azure, Microsoft, Google Cloud, CompTIA, Linux Foundation/CNCF, Python Institute, GitHub, Confluent, Databricks, HashiCorp, ISC2, Red Hat, Cisco, Oracle, and SnowPro.
  • Role paths: Help Desk and Cloud Architect.
  • One hundred eighteen exam-root sections are live now, with most routing into cheat sheets, FAQs, glossaries, study plans, and resources.
  • Newer transition lanes should keep official-fact claims conservative until vendor status is rechecked.

FAQ

Yes. TechExamLexicon publishes free study guides and review pages. The goal is to provide the explanation layer without putting the core content behind a paywall.

The current published sections are AWS, Azure, Microsoft, Google Cloud, CompTIA, Linux Foundation/CNCF, Python Institute, GitHub, Confluent, Databricks, HashiCorp, ISC2, Red Hat, Cisco, Oracle, and SnowPro, plus the Help Desk and Cloud Architect career-path pages. Together they currently expose 118 exam guides across cloud, IT support, security, networking, programming, DevOps, streaming, analytics, databases, data engineering, machine learning, and GenAI tracks.

TechExamLexicon focuses on free explanations, guide pages, and review references. MasteryExamPrep.com focuses on structured question practice, timed drills, installs, login, and progress tracking.

The pages are written for certification prep first, but they are also meant to be technically credible enough to help with help desk, networking, security, cloud, and entry-level interview reasoning.

When exact exam labels or codes matter, pages use current official wording that has been checked against the vendor. The teaching itself stays explanatory instead of copying objective bullets into long lists.
