(Network engineers must take all practical courses. The course content is XCNP practical course. The students have studied the XCIE course before, which combines the video tutorials of Cisco CCIE and Huawei HCIE, so that the two courses can be combined into one, which can not only compare but also improve learning. Efficiency, well. Then XCNP is easy to understand. Contains two NP-level courses, CCNP and HCNP (HCIP), to allow students to master Cisco and Huawei network technologies faster at the NP intermediate stage. The middle is more comfortable.)
