Career field guide · Updated September 20, 2026

Turn exam study into skills you can show.

Start with the work you want to do. Choose one path, investigate local job requirements, and build a small project that proves you can diagnose a real problem. A certificate can support that evidence; it cannot promise a job or a salary.

Before choosing an exam: inspect ten jobs

Collect ten current vacancies in your location and desired seniority. Record the tasks, required experience, recurring tools, and whether a certification is required or preferred. Separate requirements you already meet from gaps you can demonstrate in a lab. Choose your next study topic from the repeated gaps, rather than from the longest certification list.

If you are changing careers, include transferable evidence: explaining a difficult issue, following a controlled process, documenting a handover, or handling an incident. Rewrite each example around the problem, your action, and the verifiable outcome.

Five practical starting paths

IT support → systems administration

You enjoy solving user problems and explaining fixes clearly.

Learn
Operating systems, accounts, DNS, backups, basic scripting, and ticket writing.
Choose a study track
Compare CompTIA A+ objectives with local support vacancies; consider Network+ when networking is a repeated gap.
Build evidence
Build two local virtual machines. Create a user, deliberately break name resolution, diagnose it, and restore a file from backup. Publish a ticket with symptoms, evidence, fix, and verification.
Check your work
A stranger can reproduce your fix from the ticket without asking you for missing steps.

Networking → network operations

You like tracing why packets reach one destination but fail at another.

Learn
Subnetting, switching, routing, VLANs, DNS, DHCP, and reading packet captures.
Choose a study track
Compare CCNA and Network+ objectives against the equipment and responsibilities in your target jobs.
Build evidence
Draw a two-subnet network, document its address plan, and simulate a routing or VLAN fault in a lab. Record the checks that isolate the fault and the evidence that it is resolved.
Check your work
You explain both the forward and return packet path, rather than only presenting a successful ping.

Cloud support → cloud administration

You enjoy automating infrastructure and balancing permissions, reliability, and cost.

Learn
Linux or Windows administration, IAM, networks, storage, logging, and infrastructure as code.
Choose a study track
Use AWS or Azure fundamentals to learn vocabulary; consider an administrator or architect track when you can build and troubleshoot its core services.
Build evidence
Choose one small lab from the resources hub. Draw its trust boundaries, deploy within a budget, test an access failure, inspect the logs, and remove the resources. Save a sanitized runbook.
Check your work
Your README explains deployment, permissions, failure recovery, cost checks, and teardown.

IT operations → security operations

You enjoy investigating evidence and deciding which response reduces risk.

Learn
Networking, identity, operating-system logs, incident triage, and clear incident reports.
Choose a study track
Use Security+ objectives to organize security fundamentals. Match further credentials to the actual work in target vacancies.
Build evidence
Run an intentionally vulnerable application locally in an isolated lab. Reproduce one documented issue, explain the root cause, propose a fix, and describe a retest. Never test systems without authorization.
Check your work
Your report distinguishes observed evidence from assumptions and explains the limits of your test.

Linux administration → platform engineering

You enjoy command-line troubleshooting and making deployments repeatable.

Learn
Linux, Git, containers, networking, Kubernetes, observability, and recovery.
Choose a study track
Consider CKA after hands-on Kubernetes practice. A multiple-choice diagnostic alone does not demonstrate readiness for a practical exam.
Build evidence
Deploy an application in a disposable cluster. Break its Service selector, inspect endpoints and logs, repair it, then document a second independent failure and recovery.
Check your work
You can repeat the diagnosis without a walkthrough and explain why each command narrowed the problem.

A six-week plan you can adjust

  1. Week 1: choose a target. Review ten jobs, select one role, and take a diagnostic. Record uncertainty as well as wrong answers.
  2. Week 2: repair foundations. Work through the weakest objective with official documentation. Explain the concept in your own words.
  3. Week 3: build a small lab. Make it work, save the configuration, and record how you validated it.
  4. Week 4: troubleshoot. Introduce one controlled fault. Capture observations before changing settings; write a short incident report.
  5. Week 5: test transfer. Attempt fresh questions and repeat the lab with changed values. Recognition of a memorized answer is not enough.
  6. Week 6: publish and apply. Sanitize your work, write a clear README, rehearse a five-minute explanation, and apply to roles matching your demonstrated skills.

This is a planning template, not a claim that everyone becomes job-ready in six weeks. Increase the time for unfamiliar foundations and practical exams.

Check requirements at the source

Verify current objectives, prerequisites, versions, and exam format with CompTIA, Cisco, AWS, Microsoft, or CNCF. Certbie’s career paths are editorial suggestions, not vendor requirements.
