CCNA Prep is back for Season 4. This season covers the new and updated topics in the CCNA v2.0 exam blueprint, which goes live February 3rd, 2027. Still studying for the current CCNA? Stay on track. You can take the exam on the current blueprint until February. If you're just starting out, this season will help you prepare for v2.0. This episode covers two IPv6 topics that are new to the CCNA v2.0 exam: 🔹 Part 1: OSPFv3 If you already know OSPFv2 for IPv4, much of that knowledge carries over to OSPFv3 for IPv6. We configure OSPFv3 on several routers and then tune it, covering: Interface cost DR/BDR election Passive interfaces Verification and troubleshooting 🔹 Part 2: IPv6 RA Guard Learn what router advertisements (RAs) are, how they work with SLAAC (Stateless Address Autoconfiguration), and how to build an RA Guard policy. The policy protects your network from rogue, malicious or accidental devices that advertise themselves as the default gateway. 🧪 Build the lab yourself The five-node topology works with CML Free.

The CCNA v2.0 blueprint puts a fresh spotlight on IPv6 dynamic routing and modern first-hop security. In this season premiere of CCNA Prep, Hank Preston and Patrick Gargano break down everything you need to know about OSPFv3. We’ll explore how OSPFv3 builds upon familiar OSPFv2 concepts while tackling key IPv6 differences, including link-local next hops, 32-bit router ID configuration, and per-interface network enablement across broadcast and point-to-point links. Along the way, we’ll dive into first-hop defense with IPv6 RA Guard to protect clients from rogue router advertisements.

It's spooky season, and this year the scariest stories are coming from inside your own AI stack. For this special Cybersecurity Awareness Month episode of Snack Minute, Kareem Iskander and Matt DeNapoli are joined by Kyle Winters, Senior Technical Advocate on the Learn with Cisco team, for a look at what happens when Agentic AI stops behaving. Kyle walks through the year's most unsettling AI security incidents — sandbox escapes, swarms of agents building their own covert communication channels, leaked access keys turning into server takeovers, AI-assisted data theft, an algorithmic flash crash, and adaptive ransomware that studies its victim before it strikes. Then he flips to the practical side with a live demo of Defense Claw, Cisco's free, open-source tool for observing, monitoring, and putting guardrails around AI agents — including real-time prompt blocking, MCP and skill scanning, and generating an SBOM for your AI. He also previews Cisco AI Defense for teams that need custom policy at scale. Plus: everything Learn with Cisco has planned for October, including a 25% off e-learning sale on Cisco U., the 30-Day Cybersecurity Skills Challenge, and a learning bundle giveaway.

Forget spy agencies — in cybersecurity, CIA stands for Confidentiality, Integrity, and Availability. This simple triad is the foundation of smart security practices, keeping your data safe, accurate, and accessible when you need it. No secret agents required! Today, let's explore how they guide security decisions: 1.) Watch today's video to map the principles, controls, threats, and attacks for each. 2.) Write one real-world example of Confidentiality, Integrity, and Availability. ✨ Subscribe for more tech videos! @CiscoUtube ✨ Create a Cisco U.

The final stop in our CCNA 2.0 blueprint breakdown series: Domain 5 — AI and Network Operations and Management. It's only 10% of the exam, but it may be the most talked-about section of the new blueprint. In this episode, Hank and Patrick walk through the tasks in Domain 5 and explain the thinking behind them, including one line in the exam description that many candidates overlook: "as part of the exam, you may be required to evaluate output and recommendations from agentic AI and digital network assistants to support your network operations and troubleshooting activities." They also tackle the question everyone is asking — where did all the programmability go? Spoiler: it isn't gone, it's been refocused on the tools a junior network engineer actually touches day to day.

Domain 4 of the new CCNA v2.0 blueprint is worth 20% of the exam — one out of every five points — and for the first time, network services and security are combined into a single domain. In this episode, Cisco's certification team walks through what changed, what stayed the same, and why. Highlights include AAA moving from "describe" to configure, DNS finally standing on its own (with a focus on diagnosing real record issues), and the retirement of TFTP in favor of secure transfer protocols like SFTP and SCP. What you'll learn in this video: Why services and security were merged into one domain Task 4.1: Configuring AAA on Cisco routers with TACACS+ and RADIUS Task 4.2: Why TFTP is out and SFTP/SCP are in Task 4.3: NAT and PAT — still here, still important Task 4.4: Diagnosing DNS issues with A, AAAA, CNAME, MX, NS, and reverse DNS records Task 4.6: Access lists and what carried over from the current blueprint Why the reworded tasks still map to the same fundamental skills Pro tip from the team: Put the current blueprint and the v2.0 blueprint side by side and compare them yourself. Most of the "this looks so different" reactions come down to updated verbs and job-aligned wording — not brand new skills.
