Network Engineers and Security Architects must demonstrate mastery in configuring Huawei security infrastructure through the implementation of advanced firewall policies, stateful inspection, and NAT traversal mechanisms. Technical requirements include deploying site-to-site and remote-access IPSec VPNs, utilizing IKEv1/v2 negotiation protocols, and applying high-availability clusters through HRP and VGMP. Proficiency extends to configuring L2TP and SSL VPNs, optimizing traffic management via bandwidth governance, and integrating virtualization technologies within security gateways. Candidates must solve complex routing scenarios using OSPF and BGP in multi-homed security environments while ensuring effective virtual system resource partitioning, comprehensive traffic filtering, and granular security policy lifecycle management within the Huawei VRP operating system.
