New version change 1. The "Islamic State" in the original BSCI was cancelled in the new version 642-902 because it is not commonly used in enterprises; 2. Multicast is transferred to CCIE RSv4.0 CCIE ISP course. 3. The MPLS-VPN of the original ISCW was migrated to CCIE RSv4.0 and CCIE ISP courses; 4.IPSEC-VPN is moved to 642-902 E-learning course and studied as an elective course; 5. Part of VOIP content in the original ONT course was moved to Switch 642-813; 6. Because the original QOS was not deeply discussed in CCNP, it became a chicken rib, so QOS was moved to CCIERRSV 4.0 CCIEEISP course. 7. The new edition adds a troubleshooting course, which strengthens the practical application ability of network engineers on routing protocols and switching protocols. The new version of CCNP course simplifies the content, pays more attention to routing switching, and adds network debugging courses. The purpose is to enable network engineers to operate routing switching equipment more professionally and skillfully in network technology, better adapt to network management, enhance their practical ability, better adapt to work and reduce the running-in period.
