Official Exam Profile and Source Hierarchy

Know What You Are Studying For

The official credential name is Cisco Certified Support Technician (CCST) Networking, and the exam code is 100-150 CCST Networking. Cisco describes the certification as validating entry-level networking concepts and foundational skills. In practical terms, that means the exam is built around how networks operate, what devices and media participate in communication, what common protocols do, and how a beginning support technician should gather information and diagnose basic problems.

Cisco also describes CCST Networking as a first step toward CCNA certification, so you should expect a support-technician level view of topics that later become deeper in CCNA.

Use a source hierarchy when you study. The Cisco exam page, the Cisco CCST exams and training pages, Cisco's CCST FAQ, Cisco certification FAQ, the Cisco CCST Networking training page, and the Cisco Learning Network exam topics page are the sources that should anchor your decisions. A forum post, video thumbnail, or third-party chart may help you understand a topic, but it should not change your understanding of exam policy. If a third-party source says the exam has a fixed number of questions, a certain passing percentage, or a public pass rate, compare that claim to Cisco's current pages.

For this exam, Cisco states the duration is 50 minutes and says the number of questions on each exam varies. Cisco does not publish a public exact passing score or pass rate for CCST Networking.

Several official facts matter early. The exam duration is 50 minutes. The listed price is US$125 plus applicable tax. Cisco lists no prerequisites for CCST certifications; they are available to anyone. Cisco's exam page lists languages including English, Arabic, Chinese, Spanish, French, Japanese, and Portuguese, while Cisco's CCST FAQ currently lists Networking exam languages without Chinese. Treat the exam page as controlling for the exam page, and verify language availability during scheduling because the scheduling system is where your actual appointment options are confirmed.

Certification validity is also an official-policy item, not a rumor item. Cisco's current CCST information says CCST certifications earned on or after July 15, 2025 are valid for 5 years, while CCST certifications earned before July 15, 2025 remain lifetime. Recertification is by passing any CCST, associate, professional, or expert Cisco certification exam. CCST does not qualify for Continuing Education recertification.

The exam purpose should shape your study behavior. CCST Networking is not asking you to be a senior network engineer. It is asking whether you can recognize network building blocks, identify addresses and media, understand basic switching and routing behavior, follow a troubleshooting method, collect useful information, and apply foundational security concepts. That is still broad. Do not reduce preparation to memorizing isolated definitions.

A support technician needs to connect facts to symptoms: what a link light suggests, why a default gateway matters, what DHCP gives a client, why DNS failure can look like an Internet outage, and when to escalate with clean notes.

A good rule is simple: official pages define the target, hands-on practice builds the skill, and third-party explanations fill gaps only after they pass the official-source check. Keep a short exam facts page in your notes with the exam name, code, duration, price, prerequisites, delivery options, language reminder, validity rule, recertification route, and the six official topic areas. Revisit that page whenever you see a confident claim that sounds too specific to be true.

• Verify the official Cisco concept before memorizing a shortcut.
• Practice the technician action: observe, document, test, fix when supported, or escalate.
