Cisco does not publish exact percentages for CCST exams. The weightings above reflect the relative emphasis seen on the published exam topics list.
Prerequisites
None. CCST IT Support is designed as a first credential — no prior certification, no work-experience minimum, no required training. Basic computer literacy is the only practical starting point.
Why take this certification
- Lowest-risk first credential in IT. $125 USD, one 50-minute exam, lifetime validity. If you fail, you re-test 7 days later. If you pass, the credential never expires — a permanent line on your résumé that's harder to argue with than self-study claims.
- Mapped to a real job role. Tier 1 helpdesk and end-user support remain among the most common entry-level IT positions. CCST IT Support is built directly against that job description rather than against an abstract technology stack.
- On-ramp to the Cisco ladder. Sits below CCST Networking (100-150) in scope and acts as natural prep for the broader CCNA (200-301). Many candidates earn 100-140 in month one, 100-150 in month three, and CCNA within their first year.
- Useful complement to CompTIA A+. A+ remains the more widely-recognized helpdesk credential, but CCST is faster, cheaper, and signals comfort inside Cisco-heavy environments. Together they make a strong Tier 1 résumé.
What you'll learn in the CCST IT Support (100-140) exam
100-140 validates that you can be the first point of contact for end-users across the entire IT stack — diagnose a flaky laptop, walk a remote worker through a Wi-Fi fix, recognize a phishing attempt, and document the whole interaction inside a ticketing tool. The exam is intentionally broad and grounded in everyday support scenarios rather than deep specialist knowledge.
Core topic areas you'll be tested on
- Hardware: CPU and RAM basics, internal vs external storage (HDD, SSD, NVMe, removable media), display and peripheral connectors (USB-C, HDMI, DisplayPort, Thunderbolt), mobile device hardware, common failure symptoms.
- Software: Operating system installation and updates (Windows, macOS, Linux, iOS, Android), file system organization, application install/repair, drivers, backups, system restore.
- Networking: IPv4 and IPv6 addressing at a beginner level, DHCP and DNS basics, common ports and protocols (HTTP, HTTPS, SSH, FTP, SMTP), Wi-Fi standards and security (WPA2, WPA3), cables and connectors, identifying simple connectivity problems.
- Security: Malware categories (viruses, worms, ransomware, spyware), social engineering and phishing recognition, password hygiene, multi-factor authentication, basic encryption concepts, BYOD policy considerations, physical security.
- Customer service & ticket management: Ticket lifecycle (intake → classification → resolution → closure), escalation criteria, documenting reproduction steps clearly, communication soft skills, the difference between empathy and over-promising.
Scenarios you'll need to recognize
- A remote user can't connect to Wi-Fi — walking through which questions to ask first.
- An employee receives a suspicious-looking email — identifying the red flags and routing the report correctly.
- A laptop is overheating and shutting down — distinguishing between hardware, driver, and environmental causes.
- A user forgot their password and needs it reset — knowing the right verification steps before granting access.
- A ticket has been open for a week with no progress — when to escalate, and what context the next tier needs.
How the practice exams help
Each free question and every premium exam mirrors the short scenario-style format Cisco uses for CCST — a one- or two-sentence situation followed by a single best answer or a small set of correct picks. Detailed explanations cover not just why the right answer is right but why the distractors are wrong, so you learn to spot the patterns rather than memorizing answers.
How to prepare for the CCST IT Support (100-140) exam
A successful 100-140 preparation strategy combines short reading sessions, hands-on tinkering with your own devices, and timed practice exams. Recommended approach:
- Study the official exam topics (2-3 weeks). Download the CCST IT Support exam topics from the Cisco Learning Network and read each line literally — Cisco writes the blueprint deliberately, and many candidates lose points by skipping a sub-bullet that becomes a full question.
- Hands-on with your own gear (1-2 weeks). You don't need a lab — install a fresh OS in a free virtual machine (VirtualBox, Hyper-V), configure a home router, reset a phone, swap a laptop's storage drive, set up MFA on a personal account. The exam rewards candidates who have actually done these things rather than read about them.
- Free training (1 week). Cisco Networking Academy hosts a free CCST IT Support course on netacad.com. It's pitched at exactly the right level and provides the framing the official exam topics assume you understand.
- Practice exams (1 week). Take timed practice tests to identify weak areas. Detailed explanations on every answer option help you learn the reasoning, not just memorize answers. Aim for consistent 80%+ scores across all five domains before scheduling your exam.
Recommended timeline
4-6 weeks of part-time study (5-8 hours per week) for candidates with prior IT exposure. 8-10 weeks for true beginners working through Cisco Networking Academy's full course alongside hands-on practice.

What's the 100-140 passing score?
The result is reported as Pass/Fail. Cisco does not publish the numeric cut score for the CCST IT Support exam. Focus on consistent comprehension across all five domains rather than targeting a specific percentage.

What are the prerequisites for the 100-140 exam?
No formal prerequisites apply. CCST IT Support is an entry-level credential designed for high-school and college students, career changers, and helpdesk hires with no prior IT certification experience. Basic computer literacy and curiosity about how PCs, networks, and operating systems work are the only assumed starting points.
How long is the 100-140 certification valid?
CCST credentials do not expire. Once you pass 100-140, the certification is yours for life with no recertification fee or continuing-education requirement. This makes CCST IT Support a low-risk first credential to add to your résumé while you decide which CCNA or specialist track to pursue next.
What's the exam cost and can I retake it if I fail?
The Cisco 100-140 exam costs $125 USD and is delivered through Pearson VUE testing centers or via online proctoring. If you fail, Cisco requires a 7-day waiting period before retaking the same exam version, and you pay the full $125 each attempt. There is no limit on total attempts. Pearson VUE handles all scheduling, identity verification, and score reporting.
What topics are tested on the CCST IT Support exam?
CCST IT Support covers five domains: hardware fundamentals (CPUs, RAM, storage, peripherals, mobile devices), software fundamentals (operating systems, applications, file systems, drivers), networking fundamentals (IP addressing basics, common ports/protocols, Wi-Fi, cables), security fundamentals (malware, social engineering, password hygiene, MFA, BYOD), and customer service plus ticket management (escalation, documentation, communication soft skills). The blend is intentionally broad — the exam validates that you can act as the first point of contact for end-users across the entire IT stack.
How does CCST IT Support compare to CompTIA A+?
Both target entry-level IT helpdesk roles, but CompTIA A+ is significantly broader and deeper — two exams (220-1201 + 220-1202), roughly 90 questions each, $253 USD per attempt, valid 3 years. CCST IT Support is a single 50-minute exam at $125 USD with lifetime validity and a tighter scope focused on Cisco's vision of the entry-level support technician role. A+ remains the more widely recognized helpdesk credential in North American job postings, while CCST is gaining traction inside organizations that already use Cisco hardware and want a faster, cheaper on-ramp for new hires. Many career-changers earn both: CCST first as a quick win, A+ next for breadth.
What career roles does CCST IT Support open up?
CCST IT Support is targeted at entry-level helpdesk technician, IT support specialist, desktop support, and end-user support roles. It also signals readiness for internal IT apprenticeship programs and is increasingly listed as a 'preferred' credential in Tier 1 support job postings alongside CompTIA A+. After CCST IT Support, the natural next steps inside the Cisco track are CCST Networking (100-150) for those leaning toward network support, or CCNA (200-301) for a broader associate-level networking credential.
