Transferred to join WOLF-LAB, obtained CCIE certification

In July 2025, I left the company due to layoffs. I had already passed Cisco's CCNP certificate in 2011, and I always wanted to take the CCIE exam, but never had the time. This time, leaving the company was a good opportunity to take the CCIE exam. So I searched online for training institutions, and all the results were S Bo, so I signed up for the training. After more than a month, I also passed the written exam smoothly. I started preparing for the LAB. During the practice of the LAB, I would ask teachers in the group. At first, they would reply, but later they didn't reply at all, whether I posted in the group or sent private messages to the teacher. In the routing and switching part, I could practice, but there was a big difference from the exam environment, especially in the SDWAN part. The provided documents were not clear, and there were countless bugs in the experimental environment, making it impossible to practice. Later, I learned that there were people who had passed in the group, so I asked a classmate, and he recommended WOLF-LAB to me. So I went to Shanghai WOLF-LAB Miao Miao, and Jin Laoshi also patiently explained the experimental environment and the necessary precautions for practice. During the practice, I was very grateful to Jin Laoshi, Yue Laoshi, and Yang Laoshi. Whenever I encountered problems, they would reply in a timely manner, which gave me a lot of help throughout the process.

After passing the CCIE, I also completed these unfinished wishes and made up for some of my technical shortcomings. Having done networking for so many years, some technologies were only known after passing the CCIE. After completing the experimental version, WOLF-LAB also provided a standard report for comparison configuration, which allowed me to quickly find the bugs in my configuration and make modifications, which was very helpful for my preparation.

At the same time, I am very grateful to Huang Xiaoming for his advice and experience sharing, which gave me a lot of help. Without your help and guidance, I would never have passed the CCIE. WOLF-LAB is truly a良心 institution. In the future, if I have students who want to study Cisco, I will recommend WOLF-LAB, and I hope WOLF-LAB will get better and better!
