Original CCNA practice questions with full explanations, mapped to all six official exam domains. Train your subnetting, routing and CLI reasoning until the real exam feels familiar.
The CCNA is a foundational networking certification. It does not make you a senior engineer, and it will not, by itself, get you hired. What it does is prove you understand how networks actually move packets: how a switch builds its MAC table, how a router chooses a route, how a subnet is carved up, and how to read a running configuration on the CLI. For people moving into network administration, NOC, or help-desk-to-network roles, that is exactly the gap most hiring managers screen for.
A fair comparison is CompTIA Network+. Network+ is vendor-neutral and lighter on hands-on configuration, which makes it a gentler on-ramp. The CCNA goes deeper and is Cisco-specific: you are expected to configure VLANs, trunks, OSPF and ACLs, not just describe them. If your target jobs list Cisco gear or routing and switching as a requirement, the CCNA is usually the more direct signal. If you are brand new to IT entirely, starting with Network+ and then moving to CCNA is a reasonable path.
One honest caveat: the CCNA is broad. The February 2026 refresh of the 200-301 added more weight on automation, REST APIs, and AI/ML concepts in network operations alongside the classic routing and switching material. That breadth is the real challenge, which is why spaced, mixed practice across every domain beats cramming one topic.
Cisco publishes six exam domains with official weightings. The percentages below are from the current Cisco exam topics (CCNA 200-301 v1.1). Note that Cisco does not publish a fixed question count or a documented passing percentage for the live exam; scores are scaled and the exact mix of items varies per delivery, so treat the weights as a study budget rather than a guarantee of how many questions you will see.
Network components, topology architectures, cabling, TCP vs UDP, IPv4 and IPv6 addressing and subnetting, wireless principles, virtualization, and switching concepts like MAC learning and frame flooding.
VLANs across multiple switches, trunking and 802.1Q, CDP and LLDP, EtherChannel (LACP), Rapid PVST+ spanning tree, and Cisco wireless architectures including WLC and AP modes.
The heaviest domain. Reading the routing table, how a router makes a forwarding decision (longest prefix match, administrative distance, metric), IPv4 and IPv6 static routing, single-area OSPFv2, and first hop redundancy protocols.
Inside source NAT, NTP, DHCP and DNS roles, SNMP, syslog severity levels, QoS per-hop behavior, remote access with SSH, and TFTP/FTP.
Threats and mitigation, device access control, password policy and MFA, IPsec VPNs, access control lists, Layer 2 security (DHCP snooping, dynamic ARP inspection, port security), AAA, and wireless security protocols (WPA, WPA2, WPA3).
How automation changes network management, controller-based and software-defined architecture, control vs data plane, AI and machine learning in network operations, REST API characteristics, Ansible and Terraform, and JSON-encoded data.
Expect the exam to include more than plain multiple choice. CCNA deliveries commonly use drag-and-drop items and simulation or simlet questions that ask you to interpret or work with device output. Practicing the underlying reasoning, not just the trivia, is what carries over to those item types.
The candidates who pass comfortably almost always have one thing in common: they spent time on real or simulated gear, not just reading. Here is a practical approach.
Use Cisco Packet Tracer (free with Cisco's networking courses) or a free CML/GNS3 setup. Configure VLANs, trunks, OSPF and ACLs yourself until the commands are muscle memory.
You should be able to subnet without a calculator, fast. Drill VLSM, wildcard masks for ACLs, and IPv6 prefixes daily until it is automatic.
Learn to read show command output: show ip route, show ip interface brief, show running-config, show vlan brief. Most exam reasoning starts with interpreting output correctly.
Do questions from every domain in the same session rather than one topic at a time. Mixed retrieval practice surfaces the gaps that blocked review hides.
Reading a study guide creates a comfortable illusion of knowing. Practice questions break that illusion. When you have to commit to an answer and then read why the other three options are wrong, you find the exact spots where your understanding is fuzzy, before the exam finds them for you.
GetMyCert's CCNA questions are written to test reasoning across all six domains, and every question includes an explanation that covers why the correct answer is right and why each distractor is wrong. That distractor analysis is the part most resources skip, and it is where the actual learning happens. Used alongside a lab and the official Cisco exam topics, practice questions turn passive review into active recall that holds up under exam pressure.
Go to the source for the authoritative exam topics, pricing in your region, and scheduling:
Cisco does not publish a fixed number. The exam is widely reported to contain roughly 100 questions, but the exact count and item mix vary by delivery. Plan your time around the 120-minute limit rather than a specific question count.
Cisco uses scaled scoring and does not publish an official passing percentage or fixed passing score for the CCNA 200-301. Online figures such as 825 out of 1000 are unofficial estimates. Focus on consistent competence across all six domains rather than chasing a specific number.
The CCNA 200-301 is a 120-minute exam. Because it can include simulation and drag-and-drop items that take longer than multiple choice, pacing matters: do not let a single sim question eat your time.
Pricing varies by region and changes over time, and it is set by Cisco and its testing partner, not by GetMyCert. Check the official Cisco certification page for the current price where you live before you register.
Six official domains: Network Fundamentals (20%), Network Access (20%), IP Connectivity (25%), IP Services (10%), Security Fundamentals (15%), and Automation and Programmability (10%). IP Connectivity, including routing and OSPF, carries the most weight.
There are no formal prerequisites. Cisco suggests around a year of hands-on experience with Cisco solutions, but motivated beginners pass it with disciplined lab time. There is no required course you must buy first.
Generally yes. The CCNA goes deeper and expects hands-on Cisco configuration of VLANs, routing, and ACLs, while Network+ is vendor-neutral and more conceptual. Many people use Network+ as a stepping stone before the CCNA.
It depends on your background. People new to networking often spend three to five months of steady study with regular lab work; those with prior experience may need less. Subnetting fluency and CLI comfort are the two things that most shorten the timeline.
Work through original CCNA 200-301 questions with explanations across all six exam domains, and find your weak spots before exam day.
