• Standards Body Participation: Attending IETF, NANOG, attending WG meetings, commenting on RFCs.
• Cross-Functional Leadership: Working with security, cloud, application teams to resolve infrastructure gaps.
• Research & Innovation: POCs for new tech (segment routing, AltFor, P4), evaluating open-source (FRR, BIRD, VyOS).

Required Skills

• All prior level skills + the following:
• CCIE-level depth: Design methodologies, trade-offs, cutting-edge routing (segment routing, EVPN), multicast at scale.
• Cloud Integration at Enterprise Scale: AWS Direct Connect + multiple regions, Azure ExpressRoute + global reach, GCP Interconnect, multicloud routing.

CERTIFICATIONS

RATIONALE FOR EACH

• Cisco CCIE Enterprise Infrastructure (Lab + Written): Industry's premier networking credential. The 8-hour lab requires deep hands-on knowledge of designing, deploying, and troubleshooting complex enterprise networks (dual-stack, virtualization, security, automation). Candidates must pass ENCOR v1.2 written first. Passing rate ~30–40%. Gold standard for network architects.

• Cisco CCIE Alternatives (Service Provider, Data Center, Security): Pick based on specialization. Service Provider track if you work for Tier-1 carriers; Data Center if you architect hyperscaler-like environments; Security if network security is your focus.

• Cisco CCDE (Design Expert): Written exam focusing on network design methodology, rather than hands-on troubleshooting. New in 2025: CCDE Specialist badge (352-001 exam, no lab required). Faster alternative to full CCIE if design is your strength.

• Juniper JNCIE (ENT/SP/DC): Parallel to CCIE. Covers Junos OS at expert level. Practical exam required. Good alternative if Juniper is your vendor of choice.

• Arista ACE-L7, Aruba ACE: Vendor-specific expert certs. Pick if you're architecting on those platforms exclusively.

• CWNE (Certified Wireless Network Expert): Often called "CCIE of wireless." Includes practical lab and oral exam. Most rigorous wireless cert available. If wireless is a core domain, this is prestigious.

• AWS ANS-C01 + Microsoft AZ-700: Increasingly expected for cloud-forward architects. AWS is de facto standard; Azure growing in enterprise. Cloud network certs are becoming as important as CCIE for modern architects.

• TOGAF Practitioner: Not network-specific, but valuable if you're moving toward enterprise architect (EA) roles spanning infrastructure, applications, and governance. Level 1 (Practitioner) easier than Level 2 (Chartered).

Final Notes

• DevNet Rebrand (Feb 3, 2026): DevNet Professional became "CCNP Automation" and DevNet Expert became "CCIE Automation." Exam 300-435 ENAUTO replaced 300-910 DEVCOR. Existing DevNet credential holders automatically transitioned with no re-testing required.
