    #590: CCNA 2.0: What did Cisco just remove from the exam?

    02.07.2026 | 44 Min.
    Big thanks to Cisco for sponsoring this video and sponsoring my trip to Cisco Live Vegas.

    Cisco has officially announced a major update to the CCNA, moving from version 1.1 to the new CCNA 2.0 blueprint. Recorded live at Cisco Live, David Bombal sits down with Cisco certification insiders Hank and Quinn to dissect exactly what these changes mean for your career, what entry-level networking topics have been completely removed, and how the test is shifting heavily toward hands-on performance-based testing lablets.

    Learn why traditional, shallow network automation topics were pulled to make room for 2026 enterprise priorities like Agentic AI, digital network assistants, and secure device management (including mandatory AAA, secure copy protocols, and client-side security). The team breaks down the structural consolidation from six domains down to five, including the revamped 25% weight on Switching and Network Access and the newly introduced AI Network Operations and Management domain. Whether you are currently studying for your exam or just beginning your networking journey, this comprehensive breakdown explains how to align your lab practice using free tools like Cisco Packet Tracer and Cisco Modeling Labs (CML) to become truly job-ready.

    #589: How to run an AI agent INSIDE your network CLI for 2026

    30.06.2026 | 31 Min.
    Big thanks to Cisco for sponsoring this video and sponsoring my trip to Cisco Live Vegas 2026.

    Network engineers, are you ready for 2026? Learn how to deploy an AI agent directly into your CLI using Cisco MCP and Claude to automate network configurations safely. In this tutorial with Karim from Cisco, we explore how to build a custom AI skill (Iris) using Anthropic's Claude Code and Cisco's Model Context Protocol (MCP). Watch how an agent can live in your terminal to automatically read ServiceNow tickets, discover network topologies, propose BGP/firewall changes, and execute commands while keeping a "human in the loop" to prevent hallucinations. Perfect for CCNA/CCIE candidates and anyone looking to learn agentic AI without adopting complex Python programmability.

    #588: Which is Ethernet? What's the difference?

    Big thank you to DeleteMe for sponsoring this video. Use my link https://joindeleteme.com/Bombal to receive a 20% discount or use the QR Code in the video.

    Also, a Big thanks to Cisco for sponsoring my trip to Cisco Live Vegas 2026.

    Do you really need Cat 8 Ethernet for your home network in 2026? And what actually happens when you touch the end of a fiber optic cable? We break it all down with hands-on demos.

    At Cisco Live, I caught up with Jim from Fluke Networks to dive deep into the physical layer of networking. We strip away the marketing hype and look at the real-world performance of both copper and glass.

    In this video, we cover everything from the crucial safety reasons why you should never look into a fiber cable, to a microscope demonstration showing how a single speck of dirt or finger oil can cause frame errors and take down your SFP modules. We also run a live cable certification test on Cat 6 vs Cat 8 to show you exactly why Cat 6A is all you actually need for your home network, and how pros use an OTDR to find exact breaks in long fiber runs.

    If you want to build or troubleshoot networks effectively, you need to understand the physical layer.

    #587: Agentic AI is attacking your network (how to defend it)

    24.06.2026 | 16 Min.
    Are your legacy network devices a ticking time bomb? In this deep dive, Cisco’s Head of Customer Experience reveals alarming statistics from the latest Talos report: 40% of top vulnerabilities directly target end-of-life devices, and 32% are over a decade old. We explore how older infrastructure has transitioned from a mere operational drag to ground zero for a new generation of agentic AI attacks, and why the looming threat of quantum computing breaking RSA encryption means you must assess your network now. Discover how the newly launched Cisco IQ provides real-time, dynamic visibility into hardware, software, and cryptographic assets. Learn how this powerful GPS for your network connects hidden operational trails, automates TAC troubleshooting, and ensures your enterprise is quantum-ready before post-Mythos era threats cause catastrophic downtime.

    A big thank you to Cisco for sponsoring this video and for sponsoring my trip to Cisco Live Vegas 2026.

    #586: Stop zero days without a patch: You need to learn eBPF

    24.06.2026 | 21 Min.
    How has AI changed cybersecurity and enterprise networks? In this interview, Michael (General Manager for Cisco's Campus Networking) joins David Bombal to discuss the real-world impact of agentic AI, physical AI, and modern security threats. Discover why the U.S. cybersecurity agency (CISA) reports that the mean time to exploit vulnerabilities has plummeted from 10 months to just 10 hours due to AI systems chaining CVEs together. Learn how autonomous agents are shifting campus and branch environments from traditional north-south traffic to massive east-west flows, creating up to 9x the bandwidth demand. Michael breaks down how network segmentation and "least agency" protect data, how Cisco Live Protect utilizes eBPF inside the Linux kernel to create a compensating shield before a patch is ready, and how line-rate encryption with post-quantum cryptography protects against "harvest now, decrypt later" threats. Finally, find out why network engineering remains an incredibly critical, high-demand career path in 2026.
