CCST 100 140 Exam Guide: Cisco Certified Support Technician (CCST) IT Support (100-140)

What This Exam Actually Certifies

The CCST IT exam Support exam is Cisco's entry point into its certification ladder, sitting below CCNA rather than alongside it. It does not test networking configuration or Cisco hardware in any depth. Instead it checks whether someone can function on day one of a help desk or desktop support job: managing a ticket queue, following a troubleshooting process, replacing a stick of RAM without frying it, telling a user why their VPN won't connect, and recognizing a phishing email before it becomes an incident.

Cisco built this exam with Certiport as part of a three exam CCST family that also includes Networking and Cybersecurity. IT Support is the one aimed squarely at frontline technical support rather than infrastructure work.

Who This Exam Is For (and Who It's Not)

This fits someone with no formal IT background who wants a credential to put on a resume for their first help desk, desktop support, or IT support specialist role. Career changers, community college students, and people finishing Cisco's Networking Academy IT Support Specialist path are the typical candidates.

It is not the right target if the goal is a networking or security career track specifically. CCNA covers Cisco IOS configuration that this exam never touches, and CCST Cybersecurity is the better fit for someone aiming at a SOC analyst role. Someone who already holds CompTIA A+ or has a year or more of hands on desk side support experience will likely find this exam too basic to be worth the fee.

Exam Format and Structure

Fifty minutes is a tight window once you account for reading each scenario carefully, so the pace feels closer to a timed quiz than a leisurely knowledge check. Cisco has not published an exact question count, but people who've taken it consistently report somewhere in the 40 to 50 range, mixing straightforward multiple choice with drag and drop and short scenario items where you have to apply a troubleshooting step rather than just recall a fact.

There's no lab component and nothing resembling Cisco's Packet Tracer simulations used on networking exams. Everything is knowledge and judgment based, which keeps the format approachable for someone without hands on lab time.

Domains and Topics Covered

Cisco has not published percentage weightings for the CCST exams the way it does for CCNA, so treat the six domains below as roughly equal in emphasis rather than assuming any one dominates the test.

Cost Breakdown

At $125 USD, the CCST IT Support exam is one of the cheaper entry level IT certifications on the market. That figure is Cisco's published price through Pearson VUE and covers a single attempt. If you fail, Cisco requires a five calendar day wait before you can retake it, and each retake is billed at the same $125 rate since there's no discounted retake voucher for this exam. Cisco doesn't currently run region specific pricing tiers for this exam the way it does for some higher level certifications, though local taxes may apply depending on where you test.

Prerequisites and Eligibility

None. Cisco designed CCST IT Support as a true entry point, so there's no requirement to hold a prior certification or complete a specific training path before registering. Basic computer literacy, being comfortable navigating an operating system and using a mouse and keyboard, is the practical floor.

How the Exam Is Scored and What Passing Requires

Cisco uses a scaled scoring model and hasn't published the specific passing threshold for this exam publicly. You'll get a pass or fail result along with a score report at the testing center, but there's no official cut score to study toward the way there is with some vendor exams. Treat any specific passing number circulating on third party sites as an estimate rather than something to bank on.

Renewal and Recertification Requirements

This is the part of the exam page that's genuinely changed recently and worth reading carefully. Cisco updated its CCST recertification policy in 2025:

• If you earned the certification before July 15, 2025, it's valid for life. No renewal, no continuing education, nothing further required.

• If you earn it on or after July 15, 2025, it's valid for five years. To recertify at that point you need to pass a current CCST exam, any current Associate level Cisco exam, a current technology core or concentration exam, or a CCDE or CCIE level exam. Continuing education credits, which work for most other Cisco certifications, do not count toward CCST recertification.

That's a meaningful shift from the "CCST never expires" claims still floating around older blog posts and forum threads, so don't take that framing at face value if you're earning the cert now rather than in 2024.

How This Exam Compares to CompTIA A+

CompTIA A+ is the closest alternative and the one most hiring managers already recognize. The practical differences matter more than brand name recognition, though. A+ requires passing two separate exams, Core 1 and Core 2, each with its own fee, which pushes the total cost well past what CCST IT Support asks for as a single test. A+ also carries a fixed three year validity period with continuing education requirements to keep it active, compared to CCST's newer five year cycle.

Where A+ has the edge is depth and market recognition. It covers mobile devices, hardware, and security in more detail across two exams, and it's been the de facto standard for help desk hiring for over two decades. CCST IT Support is faster and cheaper to earn but doesn't carry the same weight yet with employers who've never heard of it. A reasonable strategy some candidates use is CCST IT Support as a quick, low cost way to validate readiness before committing the time and money to A+, rather than treating the two as interchangeable.

Preparation Timeline

Given the entry level scope and the absence of any Cisco specific configuration content, most people with some prior exposure to computers, even just comfortable end user experience, can prepare in three to five weeks of steady part time study. Someone starting from genuinely no IT background should plan closer to six to eight weeks, mostly to build comfort with hardware component identification and basic networking terminology like DNS and IP addressing that this exam assumes you already understand at a surface level. The exam rewards applied troubleshooting logic more than memorized facts, so working through support scenarios tends to pay off more than flashcard style review.
