CCNA v2.0 vs v1.1: What Changes in the 200-301 Exam for 2027?

When Does CCNA 200-301 v2.0 Launch?

Cisco has confirmed that the refreshed CCNA 200-301 v2.0 exam launches on February 3, 2027. Candidates preparing for the current CCNA v1.1 can continue taking that version through February 2, 2027.

This matters because Cisco is giving candidates a long transition period. If you are already well into a v1.1 study plan and intend to test before the cutoff, you do not necessarily need to restart your preparation. Cisco itself has advised current candidates to stay on track because the refresh is not a complete overhaul.

CCNA v1.1 vs CCNA v2.0 Domain Weights

The first visible change is the structure of the blueprint. CCNA v1.1 uses six domains. CCNA v2.0 consolidates them into five domains with more operational names and different weightings.

The Biggest CCNA v2.0 Change: From “Know It” to “Troubleshoot It”

The most important change is not a single new technology. It is the depth of skill Cisco expects.

Compare the language in the blueprints. The current exam often asks candidates to describe, explain, identify, or compare. The v2.0 blueprint uses action verbs such as diagnose, troubleshoot, configure, validate, interpret, use, and select much more aggressively.

For example, the current blueprint asks candidates to identify interface and cable issues. The new blueprint asks candidates to diagnose cable and interface problems involving collisions, errors, duplex mismatches, speed, distance, signal levels, pinout, and cable type.

Similarly, IPv4 and IPv6 objectives move toward troubleshooting configuration, assignment, subnetting, and prefix sizing rather than only configuring or describing them.

1. Network Infrastructure and Connectivity — 25%

The new 25% domain is broader and more diagnostic than the current Network Fundamentals section.

Interface and cabling troubleshooting becomes deeper

CCNA v2.0 explicitly expects candidates to diagnose both copper and fiber issues. The scope includes collisions, errors, mismatched duplex, speed, distance limitations, signal levels, pinouts, and cable types.

This is a shift away from simple recognition questions. Expect scenarios where the candidate has to determine whether a problem is physical, configuration-related, distance-related, or caused by an incorrect media choice.

IPv4 and IPv6 become troubleshooting objectives

IPv4 subnetting remains essential, but candidates should now be able to troubleshoot incorrect address configuration and assignment. IPv6 gets similar treatment, including prefix sizing and modified EUI-64.

For candidates preparing for other networking exams, this is also an important signal: subnetting knowledge increasingly needs to be applied to operational symptoms rather than tested only as arithmetic.

Wireless gets more operational detail

The v2.0 blueprint explicitly calls out:

• band and channel selection,
• RF characteristics,
• wireless security protocols, and
• causes of interference.

That makes wireless troubleshooting more likely to appear as a practical scenario. Candidates should be prepared to distinguish authentication problems from interference, poor channel selection, IP configuration issues, and basic reachability failures.

DHCP gets a major practical upgrade

One of the clearest changes is DHCP. CCNA v2.0 explicitly requires candidates to troubleshoot DHCPv4 clients, servers, and relays on IOS devices.

Instead of only knowing what DHCP does, practice interpreting configurations and symptoms involving ip helper-address, scopes/pools, client addressing, relay behavior, and device reachability.

2. Switching and Network Access — 25%

Switching increases from 20% to 25% and becomes one of the two largest domains in CCNA v2.0.

More realistic switch-port configuration

The new blueprint asks candidates to configure Layer 2 switch-port attributes for actual edge-host categories, including:

• desktops and printers,
• IoT appliances,
• wireless access points,
• VoIP phones,
• virtualized hosts, and
• network appliances.

This encourages scenario-based questions. Instead of simply asking what an access VLAN is, the exam can present a phone, AP, server, or appliance and ask how the switch port should be configured.

CDP and LLDP are used to validate documentation

In v1.1, candidates configure and verify CDP and LLDP. In v2.0, Cisco specifically says candidates should validate the accuracy of network documentation using CDP and LLDP.

That is a subtle but important change. You may need to compare a topology diagram or port map against discovery-protocol output and identify which documented connection is wrong.

Packet-capture output is now explicitly in scope

This is one of the most important additions for practical study. Cisco says candidates should troubleshoot basic Layer 2/Layer 3 connectivity using:

• show commands, including show logs,
• ping,
• extended ping,
• traceroute, and
• packet-capture output.

You do not need to become a packet-analysis expert, but you should be comfortable recognizing common Ethernet, ARP, IP, ICMP, DHCP, DNS, and TCP/UDP behavior in packet output.

Rapid PVST+ becomes more hands-on

The current blueprint asks candidates to interpret basic Rapid PVST+ operations. CCNA v2.0 says candidates should configure operations of Rapid PVST+.

The v2.0 outline explicitly retains root port/root bridge concepts, port states and roles, PortFast, Root Guard, Loop Guard, and BPDU Guard. BPDU Filter, which is explicitly named in v1.1, is no longer explicitly listed in the v2.0 outline.

3. IP Routing — 20%

The routing domain drops from 25% to 20%, but do not interpret that as routing becoming unimportant. Cisco increases the troubleshooting expectation and introduces a notable IPv6 routing change.

Static routing becomes troubleshooting-focused

Candidates should be able to troubleshoot IPv4 and IPv6:

• default routes,
• network routes,
• host routes, and
• floating static routes.

NEW / EXPANDED OSPFv3 for IPv6

The current CCNA blueprint explicitly tests single-area OSPFv2. CCNA v2.0 expands this to OSPFv2 for IPv4 and OSPFv3 for IPv6.

This is one of the clearest new study areas. Candidates should understand configuration and behavior for:

• neighbor adjacencies,
• point-to-point networks,
• broadcast networks and DR/BDR selection, and
• router IDs.

If your current CCNA study resources cover only OSPFv2, add a dedicated OSPFv3 study and practice block.

HSRP and VRRP are now explicitly named

The current blueprint broadly asks candidates to describe first-hop redundancy protocol concepts. CCNA v2.0 specifically requires candidates to interpret the operational status of HSRP and VRRP.

That means command-output interpretation is more important than memorizing a generic FHRP definition.

4. Network Services and Security — 20%

CCNA v2.0 combines areas that previously lived under IP Services and Security Fundamentals. The result is a domain that feels much more like day-to-day network administration.

DEEPER AAA becomes configuration-oriented

The current exam asks candidates to compare authentication, authorization, and accounting concepts. V2.0 goes further: candidates should be able to configure network devices with local usernames and as an AAA client using TACACS+ and RADIUS for management.

Study the operational differences between local authentication, TACACS+, and RADIUS, and understand how a network device participates as an AAA client.

NEW / MODERNIZED SFTP and SCP

CCNA v1.1 explicitly mentions TFTP and FTP capabilities. V2.0 instead calls out managing device configuration and software files using secure file transfer with SFTP and SCP.

This reflects modern operational practice: candidates should recognize secure methods for moving configurations and software images rather than focusing only on older clear-text transfer protocols.

NEW / EXPANDED DNS record troubleshooting

DNS receives a surprisingly significant upgrade. Instead of simply explaining the role of DNS, v2.0 requires candidates to diagnose DNS record issues affecting host, web-application, and mail-server access.

The blueprint explicitly names:

• A — IPv4 host mapping,
• AAAA — IPv6 host mapping,
• CNAME — aliases,
• MX — mail exchange,
• NS — authoritative name servers, and
• PTR — reverse lookup.

A candidate should be able to reason through symptoms such as “the web server works by IP but not by name,” “mail delivery fails while the website still resolves,” or “reverse DNS is incorrect.”

Layer 2 security expands

V2.0 retains DHCP snooping, Dynamic ARP Inspection, and port security, and explicitly adds:

• Storm Control, and
• IPv6 RA Guard.

RA Guard is especially noteworthy because it extends CCNA security coverage into IPv6 first-hop protection.

NAT/PAT and ACLs remain important

Candidates still need practical NAT/PAT and ACL skills. The v2.0 blueprint explicitly references NAT/PAT on IOS XE routers and IPv4 ACLs in standard, extended, numbered, and named forms.

5. AI, and Network Operations and Management — 10%

This domain is likely to attract the most attention because Cisco is moving far beyond simply asking what AI is.

NEW Agentic AI in network operations

CCNA v2.0 explicitly requires candidates to understand the role of agentic AI in network operations.

More importantly, Cisco states in the exam description that candidates may be required to evaluate output and recommendations from agentic AI and digital network assistants to support network operations and troubleshooting.

This implies an important exam skill: the AI may suggest an action, but the candidate still needs enough networking knowledge to determine whether that recommendation makes sense.

NEW Prompt selection for network operations

The v2.0 blueprint explicitly includes selecting a prompt for a generative AI system. Cisco calls out prompt components such as:

• data classification,
• output format,
• persona, and
• instructions.

A realistic exam question could ask which prompt best instructs an AI assistant to analyze sanitized switch logs, identify probable root causes, and return findings in a specific structure.

The key is not “prompt engineering” as a separate career skill. It is using an AI assistant safely and effectively as part of network operations.

Ansible becomes more practical

CCNA v1.1 asks candidates to recognize capabilities of tools such as Ansible and Terraform. V2.0 specifically asks candidates to use configuration-management mechanisms such as Ansible to execute commands.

That wording suggests candidates should be ready to understand what an Ansible operation is doing and interpret its effect, not merely identify Ansible as a configuration-management tool.

SNMP and syslog remain

SNMP remains part of network operations, while syslog becomes explicitly interpretive: candidates should understand message content, severity levels, and facilities.

Which Current CCNA Topics Are No Longer Explicitly Listed?

A blueprint comparison also reveals several v1.1 objectives that are not explicitly named in the v2.0 outline.

What Does the CCNA v2.0 Refresh Tell Us About Cisco’s Direction?

The blueprint suggests a clear shift in what Cisco considers an entry-level network professional.

The older model could be summarized as:

Networking fundamentals + configuration + introductory automation/programming concepts.

CCNA v2.0 looks more like:

Networking fundamentals + practical troubleshooting + secure operations + AI-assisted network management.

Cisco is not removing networking fundamentals. It is asking candidates to apply them in more realistic situations.

That distinction matters for anyone using CCNA as the foundation for later certifications such as CCNP Enterprise, cybersecurity certifications, cloud networking, or network automation. Strong operational reasoning will transfer better than memorizing isolated facts.

How Should You Prepare for CCNA v2.0 Differently?

1. Keep subnetting, routing, switching, and VLAN fundamentals strong

Do not overreact to the AI headlines. CCNA is still a networking certification. IP addressing, switching, routing tables, VLANs, trunks, EtherChannel, spanning tree, ACLs, NAT, wireless fundamentals, and network services remain central.

2. Add an explicit OSPFv3 study block

If your course or book was built around v1.1, verify that it includes OSPFv3 for IPv6. Do not assume OSPFv2 knowledge alone is enough.

3. Practice troubleshooting from evidence

Instead of studying only with questions such as “What does this command do?”, also practice questions such as:

PC1 cannot reach the default gateway.
SW1 shows the correct access VLAN.
The DHCP client has an APIPA/self-assigned address.
The DHCP server is on another subnet.

Which configuration should you verify first on the router?

The objective is to develop a repeatable diagnostic process: identify the layer, inspect evidence, isolate the failure domain, and choose the least disruptive corrective action.

4. Learn to read command output, logs, and packet information

Build familiarity with routing tables, interface counters, VLAN/trunk information, spanning-tree output, CDP/LLDP neighbors, DHCP behavior, HSRP/VRRP state, syslog messages, and basic packet-capture data.

5. Study DNS like a network operator

Know what A, AAAA, CNAME, MX, NS, and PTR records do, but go one step further: be able to identify which record is likely responsible for a given failure.

6. Learn practical AAA and Layer 2 security

Do not stop at defining authentication, authorization, and accounting. Be prepared for TACACS+/RADIUS client scenarios, DHCP snooping, Dynamic ARP Inspection, port security, Storm Control, and RA Guard.

7. Treat AI as a tool you must validate

For CCNA v2.0, you should understand both how to ask an AI system for useful network-operations output and how to judge whether the recommendation is technically sound.

A useful practice pattern is:

1. Read a network symptom and a small amount of evidence.
2. Review an AI-generated diagnosis or remediation suggestion.
3. Check it against routing, switching, addressing, or security fundamentals.
4. Decide whether to accept, reject, or modify the recommendation.

8. Use more labs and scenario-based practice

The closer your study method resembles actual network operations, the better aligned it will be with Cisco’s stated direction for the refresh. Use command-line labs, Packet Tracer or equivalent environments, troubleshooting scenarios, packet examples, and exam-style questions that require interpretation rather than recall.

Should You Take CCNA v1.1 Now or Wait for v2.0?

If you are already preparing and can realistically take the exam by February 2, 2027, there is little reason to abandon your current plan. Cisco has explicitly encouraged current candidates to continue toward v1.1 rather than delaying solely because a refresh is coming.

On the other hand, if you are starting later in 2026 and expect your test date to fall in February 2027 or beyond, begin mapping your study plan to v2.0 now.

Frequently Asked Questions About CCNA v2.0

Final Takeaway

CCNA v2.0 is best understood as an evolution from foundational networking knowledge toward job-ready network operations. The core is still routing, switching, addressing, wireless, security, and network services. What changes is the way Cisco expects candidates to use that knowledge.

You should be ready to troubleshoot rather than only recognize, interpret rather than only define, and validate rather than blindly accept — including recommendations produced by AI tools.

For CCNA candidates, that is good news. The skills that matter more in v2.0 — troubleshooting, IPv6 routing, secure operations, packet interpretation, and disciplined use of AI — are also skills that transfer directly to real networking roles and more advanced certifications.
