CCIE

Every CCIE Security v6.1 candidate hits the same question early in their prep: do I master ASA first, or dive straight into FTD? Reddit threads are full of conflicting advice. Some candidates say FTD dominates the lab. Others insist ASA fundamentals are non-negotiable. The truth — as usual — is more nuanced than either camp admits. I’ve spent significant time dissecting the v6.1 blueprint, lab reports from recent candidates, and the actual platform behaviors you’ll encounter under exam pressure. Here’s the definitive breakdown. ...

Choosing the right lab environment can make or break your CCIE journey. You’ll spend hundreds — maybe thousands — of hours labbing before exam day, so the platform you pick matters more than most candidates realize. The three dominant options in 2026 are Cisco Modeling Labs (CML), INE’s cloud-based labs, and GNS3 (the open-source veteran). Each has real strengths and real limitations. This guide breaks down the honest comparison so you can stop second-guessing and start labbing. ...

If you’ve been tracking Cisco’s certification ecosystem, you already know something big dropped in February 2026: DevNet Expert is now CCIE Automation. This isn’t just a name change — it’s a strategic signal from Cisco that automation has earned its place at the expert-level table alongside Enterprise Infrastructure, Security, Data Center, and Service Provider. Let’s break down exactly what changed, what stayed the same, who should care, and how to position yourself for this new track. ...

If you’re grinding through OSPF LSA types and BGP path selection at 2 AM, you’ve probably had this thought: “Will I actually use any of this?” You’re not alone. A recent Reddit thread in r/networking went viral when a junior network engineer — actively studying for the CCIE — discovered that senior engineers at his company couldn’t even explain the OSPF templates they’d been deploying for years. The thread exploded with nearly 100 comments, and the consensus was surprisingly honest: most network engineers rarely make L3 routing changes in their day-to-day work. ...

There’s a persistent myth floating around Reddit and networking forums: “Data center networking is dying. It’s all cloud now.” Let me kill that with numbers. The US data center market exceeded $135 billion in 2025, and it’s accelerating — driven almost entirely by AI workload expansion. Every hyperscaler, every enterprise running private cloud, every financial institution with latency requirements needs engineers who understand data center fabric at an expert level. ...

The CCIE Enterprise Infrastructure lab exam is one of the most demanding certifications in the networking industry. With a first-attempt pass rate hovering around 20%, most candidates walk in underprepared — and walk out with a failing score. But it doesn’t have to be that way. After years of helping engineers achieve their CCIE on the first attempt, I’ve distilled the strategies that separate first-time passers from repeat takers. This isn’t theory — it’s a battle-tested playbook. ...

Every week I get the same question from engineers starting their CCIE journey: “Should I go with INE or CBT Nuggets?” It sounds simple, but the answer depends entirely on where you are in your preparation and what you actually need to pass the lab. I’ve used both platforms extensively over the years, and I’ve coached engineers who swear by each one. The truth is, they’re not really competing for the same job in your study plan. Let me break down exactly what each platform delivers — and where each one falls short — so you can spend your money and your time wisely. ...

Every year, the same question pops up on Reddit, Cisco Learning Network, and every networking Slack channel: is CCIE worth it anymore? With cloud certifications multiplying, automation eating into traditional network roles, and the exam costing five figures to pursue — it’s a fair question. Here’s the short answer: yes, but not for everyone. The CCIE still delivers one of the strongest ROIs of any IT certification in 2026. But the math only works if you go in with the right expectations, the right preparation, and a clear understanding of what you’re actually buying. ...
