CCNA v2.0 (200-301): The 2027 Exam Revamp, Explained

Same exam code, new exam

On May 20, 2026, Cisco's Learning Network blog announced the CCNA's biggest overhaul in more than six years. (The CCNA is Cisco's entry-level networking certification — the most-recognized first credential for network engineers, the one hiring managers ask for.) The current 200-301 v1.1 exam retires on February 2, 2027; the new 200-301 v2.0 blueprint goes live the next day, February 3, 2027. One honest nuance: Cisco itself says "February 2027" — the exact day is reported consistently by independent training outlets (INE, Network World, 101labs, CertEmpire), and Cisco's own blog carries the announcement and the new blueprint.

Here is the twist that confuses everyone: the exam code does not change. It is still 200-301. The number on the door stays the same; the room behind it gets remodeled — Cisco calls it a major structural rework, with more than 20% of the blueprint changed. The format you already know (120 minutes) is unchanged, and there is no announced change to the question count or passing score — anything you read quoting ~100 questions or 825/1000 for v2.0 is carried over from v1.x experience, not an official v2.0 number.

The new shape: five domains

Six domains become five, and the weights move:

The newcomer is domain 5.0, "AI and Network Operations" (10%). Do not mistake it for AI theory: the exam tests AI as an operations tool. Cisco's own headline is that you "may be required to evaluate output and recommendations from agentic AI and digital network assistants" — during troubleshooting. The blueprint also names prompt engineering for generative AI explicitly, down to the four prompt elements: data classification, output format, persona, and instructions. The rest of the domain is the practical management layer: network management approaches (device-based, controller-based, automation-based, cloud-based, Infrastructure as Code), plus SNMP, Ansible, and syslog carried over from v1.1.

The three big shifts

1. Troubleshooting is back. This is the philosophical headline. Roughly 28–30% of v2.0 topics now use "troubleshoot" or "diagnose" verbs; v1.0 and v1.1 had zero. The exam stops asking only "what is this?" and starts asking "it's broken — find it." That includes packet-capture-based troubleshooting (open a capture, read the story like a flight recorder), DHCPv4 server-side troubleshooting, DNS diagnosis (A, AAAA, CNAME, MX, NS, PTR records), and client connectivity troubleshooting on Windows, macOS, and Linux.
2. AI enters as a tool, not a topic. You are not being asked to explain transformers. You are being asked to do what working engineers already do: take an AI assistant's suggestion, check it against the network in front of you, and decide whether to trust it. If you have been using AI to sanity-check your lab work, you have been pre-studying without knowing it.
3. The theory gets pruned. The old "Automation and Programmability" domain is gone as a standalone section, its useful parts absorbed into the new AI/operations domain. Shown the door: REST-API/JSON/CRUD theory, Terraform, controller-based architecture detail, wireless LAN GUI configuration and Cisco wireless architectures, QoS marking theory (PHB/classification/marking), NTP client/server, and several foundational-theory topics — network-device roles, spine-leaf topology theory, TCP-vs-UDP comparisons, detailed IPv6 address types, and MAC learning/aging mechanics. The message is consistent: less memorizing slides, more fixing networks.

What's actually new on the topic list

Beyond the domains, the topic-level additions tell you exactly where to spend lab hours: OSPFv3 for IPv6 (v1.1 was OSPFv2 only); explicit HSRP/VRRP operational interpretation — reading a first-hop-redundancy setup and knowing who should be active; SFTP/SCP replacing TFTP/FTP for file transfers; storm control and RA guard on access ports; PoE and edge-host-aware access-port configuration; "use Ansible" as a genuinely testable IaC skill rather than a vocabulary word; and cable-plant diagnostics — signal level, pinout, distance. Notice the pattern: every addition is something a junior engineer touches with their hands.

Should you test now or wait?

The decision is simpler than the forums make it. If you can be genuinely exam-ready by February 2, 2027, take v1.1. A pass is a CCNA for the standard three years — Cisco's policy is explicit that certifications earned under any blueprint version stay valid for the full three-year period with no retroactive effect, and the announcement blog says existing certs remain "valid, respected, and recognized." There is no asterisk on a v1.1 badge.

If you are starting from zero right now, plan for v2.0. The fundamentals carry over — 90% of the exam is still infrastructure, switching, routing, services, and security — so every hour of subnetting, OSPF, and VLAN labbing is safe. What changes is the seasoning: do not sink weeks into the dropped theory (Terraform, REST/JSON CRUD, wireless GUI clicks), and start practicing the new hands-on skills now — Ansible basics, reading packet captures, DHCP and DNS troubleshooting. Our CCNA vs Network+ vs CCNP comparison still answers the "is this cert worth it" question, our home lab guide is how you build the troubleshooting reps v2.0 demands, and the Wireshark filter builder plus the subnet quiz are the two free tools this exam rewards most.

Renewing an existing CCNA? Nothing changes: retake the (then-current) exam, earn 30 Cisco Continuing Education credits, or pass a higher-level exam.

What the revamp tells you about the job

Read the blueprint as a hiring signal. Employers — and now Cisco — expect junior engineers to troubleshoot rather than recite, to automate with real tools (Ansible, not acronyms), and to treat AI assistants as part of the workflow rather than a shortcut. That matches what current job postings keep saying: software, automation, and IaC are expected now, not bonus points. The CCNA just made it official.
