3.2. Advanced Routing, Switching & Infrastructure
● Expert Routing & WAN: Deep, authoritative understanding of advanced routing protocols. Proven experience designing and optimizing OSPF in complex multi-area environments, BGP (iBGP/eBGP with complex route policies/attributes), and large-scale SD-WAN deployments.
● Layer 2/3 Redundancy & Segmentations: Extensive experience with complex Spanning Tree implementations (PVRST+, MSTP) and multi-layer redundancy (HSRP/VRRP, GLBP). Expertise in design and deployment of advanced VLAN structures, Private VLANs (PVLAN), and Virtual Routing and Forwarding (VRF).
● Data Center Technologies: Mastery of data center switching fabrics, Cisco Nexus switches (NX-OS), vPC (Virtual Port Channels), VXLAN, and Quality of Service (QoS) design for traffic prioritization.

3.3. Enterprise Security, Cryptography & Firewalls
● Next-Generation Firewalls (NGFW): Expert-level configuration and lifecycle management of enterprise-grade firewalls, specifically Fortigate and Palo Alto clusters. Advanced implementation of High Availability (HA), Intrusion Prevention Systems (IPS), SSL Inspection, and Deep Packet Inspection (DPI).
● Cryptography & PKI Infrastructure: Thorough understanding of cryptographic protocols. Experience implementing highly secure Site-to-Site IPsec VPNs and remote-access SSL VPNs utilizing advanced symmetric/asymmetric algorithms (AES, RSA, ECC). Strong command of Public Key Infrastructure (PKI) concepts, including certificate lifecycle, Certificate Authorities, and handling revocation lists (CRLs/OCSP).

3.4. Enterprise WLAN & Mobility
● Wireless Infrastructure: Expertise in designing, surveying, and tuning high-density enterprise wireless networks. Advanced management of centralized Wireless LAN
