The experiences of successful users are undoubtedly very important to us, because they not only know the road to success, but also know the road to failure, these experiences are of great reference value to latecomers. Friends who have already passed ccna are very willing to share their experiences with you. Some netizens collected some experiences and sorted them out, hoping they could help those who are preparing for the
