Cisco's new CCNA blueprint is here, and Domain 1 — Network Infrastructure and Connectivity — is the biggest piece of the exam at 25% of your questions. In this episode, CCNA Experts Hank and Patrick walk through what changed and why. The headline shift: troubleshoot now appears throughout the domain where the current CCNA 1.1 leaned heavily on configuration and verification. That's intentional. With CCST Networking covering the fundamentals (basic IP addressing, foundational configuration), the CCNA trims that groundwork and steps up to the tasks a junior network engineer actually faces every day.

Domain 2 is coming up next. Stay tuned.

As network infrastructure evolves toward API-driven, programmatic management, traditional security models are struggling to keep pace. While protocols like gNMI, gNOI, and gRPC have transformed network automation, they have also created a gap in how we secure the management plane. Legacy AAA (Authentication, Authorization, and Accounting) models and manual certificate management are no longer sufficient for the speed and scale of modern, dynamic networks. This session demystifies the OpenConfig security framework, offering a practical approach to modernizing your security posture. ✨ Subscribe for more tech videos! @CiscoUtube ✨ Create a Cisco U.

It's a rare two-host episode — just Matt and Kareem — and Kareem brought a demo worth the extra time. Meet Iris: an agent skill (named after Kareem's daughter) that keeps an eye on your network. Built on top of the MCP servers we've covered across previous Snack Minutes, Iris lives where a lot of network engineers still live — the CLI. No context switching to a browser or desktop app. SSH into a device, pull the logs, launch Claude Code, and let it troubleshoot inline in the terminal you're already working in. What Kareem walks through: Why "AI for the network" usually assumes engineers will leave their comfort zone — and why an agent skill fixes that How Claude Code and Codex go beyond writing code and start automating real operational workflows The anatomy of an agent skill: CLAUDE.md for guiding principles, SKILL.md for the workflow, plus front matter, folders for your docs, and your existing Ansible/Terraform/Netmiko scripts Iris auto-discovering its own tooling — ServiceNow, Cisco Modeling Labs, Meraki, NetBox, and Splunk — then propagating out to learn the topology and source of truth Writing guardrails explicitly: discover before you assume, verify before and after every change, never push without approval, if something looks wrong, stop A live run against ServiceNow incident 1003 — a request to connect a new AWS dev VPC to an on-prem site Iris catching an ACL blocking ping that was never mentioned in the ticket The bigger takeaway: the years of cognitive shortcuts you take for granted have to be written down for a model to follow them. Once they are, that skill becomes transferable — hand it to your teammates and the whole operations team works from the same rules. Matt and Kareem also get into the part that matters most: humans stay in the loop. Not as someone clicking an approve button, but as the expertise that catches what the model gets wrong. If you can't read an ACL or configure iBGP, you can't approve the change — and you definitely can't debug it when it breaks. Also discussed: model selection and cost. Kareem is running Opus on high effort via Amazon Bedrock, and explains why Sonnet wasn't holding up for this workload — plus the open question of whether a routing layer that picks the model for you just adds another layer of cost. 🔗 Try Iris: The skill is on GitHub — link below. Clone it, break it, and rewrite it to match how you operate. And yes, there's a skill that helps you build skills. https://github.com/kiskander/iris 👉 Subscribe for more Snack Minute episodes on AI, automation, and the tools network engineers actually use.

Timing is everything when you're working through lablets — here's the strategy. Aim for 8–10 minutes per lablet. You'll get five of them, so that pacing keeps you on track. If you look up and it's 20 minutes in and you're still on the first one, it's time to make a decision and keep moving. Never skip an entire lablet. Each one carries a lot of points — a single lablet isn't the equivalent of one multiple-choice question. It might be worth five or seven. Skipping one leaves a big gap in your score. Remember: partial credit counts. Tackle as much of each lablet as you can, even if you can't complete every task. The time guidance you're given is a real signal of how heavily these lablets are weighted. Use it to plan your approach. 👉 Follow for more practical Cisco lab and certification guidance. #Cisco #CCNA #NetworkEngineer #Networking #CiscoLabs #ITCertification #ExamStrategy #Shorts

Before you start any Cisco hands-on lab, there are a few ground rules that can make or break your score. Rule 1 — Only change what the task asks for. Don't go off script. Stay focused on the tasks in front of you. Rule 2 — Never change usernames, passwords, or hostnames. You won't be asked to, and doing it breaks our ability to evaluate your work. That means losing all the points for those questions. Yes, "cisco" is a weak password — but the lab isn't the place to fix that. Rule 3 — Save your configurations. Just like in a real network, the last thing you do on every device is run copy run start. Commit those changes. Keep these three in mind for every lab and you'll avoid the most common avoidable point losses. 👉 Follow for more practical Cisco lab and certification guidance. #Cisco #CCNA #NetworkEngineer #Networking #CiscoLabs #ITCertification #Shorts

Struggling to get through your network engineering studies? You're not alone — and there's no shortcut. In this short clip, we talk through the honest reality of learning to configure ACLs, interfaces, basic routing, and security. It's a lot to take on, and the only reliable path forward is hands-on repetition. Think of it like learning a trade: electricians and plumbers don't get good by reading about it, and neither do network engineers. The advice is simple: put in the lab hours. Use Cisco Modeling Labs (CML), use Packet Tracer, and if you have access to real hardware, get your hands on it. Configure static routes 100 times before you ever sit down for an exam or a job interview. The skills come from the effort.
