What to look for in a good CCNA practice exam
- Weighted to Cisco's six domains: CCNA 200-301 is weighted across network fundamentals, network access, IP connectivity (the largest single domain), IP services, security fundamentals, and automation & programmability. Practice should mirror that mix, with real depth in IP connectivity (routing) specifically.
- Configuration and troubleshooting scenarios, not just definitions: CCNA asks you to interpret a topology or config snippet and decide what's wrong or what to configure next (VLANs, OSPF, ACLs, NAT). Good questions present that kind of scenario rather than asking "what does VLAN stand for."
- Covers automation and programmability, not just classic networking: It's a newer, smaller domain covering things like REST APIs, JSON, and controller-based networking. Banks that only cover traditional switching/routing content leave this domain untested.
- Explains the reasoning behind config choices: For a question about OSPF cost or ACL placement, the explanation should cover the underlying routing/security logic, not just state the right command.
- Enough depth in IP connectivity specifically: It's the single biggest domain and covers both IPv4 and IPv6 routing. Shallow coverage here costs the most points.
- Domain-level readiness tracking across all six domains: So gaps in, say, automation or security fundamentals don't hide behind a decent overall score.
Common mistakes people make with CCNA practice exams
- Memorizing configs instead of understanding the topology logic: CCNA scenarios change the topology or requirement enough that memorized command sequences without understanding why they're needed don't transfer.
- Using outdated dumps from older CCNA versions: CCNA has been restructured more than once, most recently into the single 200-301 exam. Old material can teach retired topics or, worse, be leaked real content, which is against Cisco's certification agreement.
- Skipping the automation & programmability domain: It's a smaller domain, but candidates who've never touched REST APIs or JSON often skip it entirely in prep and lose those points needlessly, since the exam does test it.
- Not practicing config/troubleshooting scenarios under time pressure: Reading about a concept isn't the same as diagnosing it quickly in a described topology. Timed, scenario-based mocks build that speed.
- Under-preparing IP connectivity because routing feels "settled": It's the largest domain. Candidates often assume routing basics are solid without testing themselves on the specific scenario style CCNA uses.
How CertGrid approaches CCNA practice
CertGrid's CCNA bank has 705 questions across all six exam domains, and full mock exams draw from the same weighting Cisco uses for the real exam, so IP connectivity - the largest domain - gets proportional coverage (see the breakdown below). Every question explains the networking or security logic behind the correct configuration and why each other option would misconfigure or break the scenario, with domain-level readiness tracking after every attempt. A fixed set of 20 free practice questions with basic explanations lets you try it first; the full bank, complete explanations, and timed 120 min mocks are part of the Pro plan.
- Network Fundamentals20% of the exam
- Network Access20% of the exam
- IP Connectivity25% of the exam
- IP Services10% of the exam
- Security Fundamentals15% of the exam
- Automation and Programmability10% of the exam

Frequently asked questions
How many CCNA practice questions should I do?
Most candidates work through several hundred questions across all six domains, with extra repetition on IP connectivity and network access/fundamentals, then take 2-3 full-length, timed mocks once scores are consistently above target.
What practice score means I'm ready for CCNA?
Consistently scoring well above your target on timed, full-length mocks across all six domains - not just the domains you find interesting - is a reasonable readiness signal, since Cisco's real scoring is scaled and not disclosed in exact detail.
Are these real Cisco exam questions?
No. CertGrid is independent and not affiliated with Cisco. Our questions are original, written to the published CCNA 200-301 exam topics. We do not provide, and do not condone, leaked or braindump content - Cisco's certification agreement explicitly prohibits using real exam questions.
Does CertGrid include drag-and-drop or simulation-style questions like the real CCNA?
CertGrid's CCNA questions are multiple-choice and multiple-select, testing the same configuration and troubleshooting judgment the real exam's drag-and-drop and simulation items test, but they are not an interactive network simulator.
How current is the CCNA bank?
Last reviewed September 12, 2026 against the current CCNA 200-301 exam topics, and re-reviewed when Cisco updates them.
What should I take after CCNA?
CCNP Enterprise (starting with ENCOR) is the standard next step for enterprise networking, CCNP Security (SCOR) for a security path, and CCNA Automation (the DevNet-associate track) if you want to go deeper on automation and programmability.
