I have more than ten years of hands-on experience in enterprise network operations. I currently work for an international law firm in Beijing, where I mainly support and maintain SD-WAN and MPLS wide area networks.

Over the years, I realized that practical experience picked up here and there wasn't enough when I ran into advanced technical problems involving complex routing architectures. I decided to pursue the CCIE Enterprise Infrastructure certification to build a stronger, more complete skill set.

I made my first attempt in 2024 after training with another provider, but I didn't pass. The study materials were incomplete, and I hadn't planned my practice schedule well enough. Later, a former colleague recommended WOLF-LAB, so I chose them for my second round of preparation.

My experience with WOLF-LAB was excellent. Their study materials were complete, well organized, and detailed, which addressed one of the biggest problems I'd had the first time around. The instructors knew the material inside and out, answered questions quickly, and were consistently supportive.

The report feature built into the practice racks was especially helpful. It compared my configuration against the expected setup, so I could quickly find anything I'd missed and correct habits that could cost me points on the exam. There were plenty of rack sessions available, so I never had to fight for a time slot. The remote connection was also fast and stable. Even though my studying was spread out over the course of a year, I was still able to get enough hands-on practice.

After comparing WOLF-LAB with several other training providers, I found their solutions clear, consistent, and closely aligned with the way the exam is scored. For me, WOLF-LAB turned out to be a real find.

Before I took the CCIE lab exam, an instructor reviewed my practice results with me in a one-on-one session. We worked on the areas where I was still making mistakes, went over practical exam-day strategies, and talked through the anxiety I was feeling about a second attempt.

After several months of sticking with it, I passed. I'm sincerely grateful to the WOLF-LAB instructors for their careful guidance and to everyone in the study group for encouraging one another along the way.

This round of preparation also helped me organize my technical knowledge into a much more complete system. Going forward, I'll apply what I learned to my day-to-day SD-WAN and MPLS work and keep building my skills.
