Azure Network Engineer Career Roadmap: AZ-104 → AZ-700 → Senior Network Architect

An Azure Network Engineer designs, implements, and operates large-scale Azure networks (VNet, Hub-Spoke, Virtual WAN, ExpressRoute, Azure Firewall, Front Door, Private Link). Demand is strong on hybrid and multi-cloud network projects. Senior network engineers earn in the JPY 9-13M range, and network architects reach JPY 12-18M. This article lays out the standard route from zero to Azure Network Engineer (AZ-900 → AZ-104 → AZ-700), plus the dual-stack strategy of pairing it with Cisco CCNP or AWS Advanced Networking.

The Standard Route: AZ-900 → AZ-104 → AZ-700

Here is the standard path to becoming an Azure Network Engineer.

Standard study time: 9-12 months from zero experience, 5-8 months with networking background, and 4-6 months for those with Cisco / on-prem networking experience.

Why On-Prem Network Fundamentals Matter

AZ-700 assumes baseline networking knowledge — TCP/IP, routing, switching, firewalls, VPN — and tests how to implement those concepts using Azure services. If Cisco CCNA-level fundamentals are second nature to you, your study efficiency improves dramatically. Beginners are advised to spend 1-2 months on Cisco CCNA / CompTIA Network+ equivalent fundamentals first. That said, pure cloud-native networking designs (Hub-Spoke, Virtual WAN, Front Door, etc.) are new territory for most candidates, so a sizable chunk of your AZ-700 prep will be spent there.

Core AZ-700 Topics

The Azure networking services covered by AZ-700 are listed below.

• VNet design: Subnet, NSG, ASG, Route Table, VNet Peering (Regional / Global)
• Hybrid connectivity: VPN Gateway (Site-to-Site / Point-to-Site), ExpressRoute, ExpressRoute Direct, ExpressRoute Global Reach
• Large-scale network architecture: Hub-Spoke, Mesh, Virtual WAN, Virtual WAN Branch Connect
• Security: Azure Firewall (Standard / Premium), Azure Firewall Manager, NVA (Network Virtual Appliance), DDoS Protection (Network / IP)
• L7 traffic control: Application Gateway (WAF v2), Front Door (Standard / Premium), Azure CDN, Traffic Manager
• L4 load balancers: Azure Load Balancer (Standard / Public / Internal), Cross-region Load Balancer
• Private connectivity: Private Endpoint, Private Link Service, Service Endpoint
• DNS: Azure DNS, Private DNS Zones, DNS Private Resolver
• Monitoring: Network Watcher, Connection Monitor, NSG Flow Logs, Traffic Analytics

Choosing Between ExpressRoute and VPN Gateway

This is one of the most common selection scenarios on the exam.

Multi-Cloud Networking

As Japanese enterprises accelerate hybrid and multi-cloud adoption, demand for multi-cloud networking specialists is climbing sharply.

Security Integration

Security integration is a non-negotiable skill for network engineers.

• SC-300 (Identity Admin): strengthens network authentication via Entra ID integration.
• SC-500 (successor to AZ-500, GA expected 2026-09): comprehensive coverage of Azure security implementation.
• SC-100 (Cybersecurity Architect Expert): zero-trust network architecture.

Standard Career Path

1. Network technician (3-5 years): Cisco / on-prem networking, routing and switching fundamentals. Earn AZ-900.
2. Junior cloud network engineer (1-3 years): Building Azure VNets, basic VPN / ExpressRoute connectivity. Earn AZ-104.
3. Mid-level cloud network engineer (2-3 years): Hub-Spoke design, Virtual WAN rollouts, large-scale network operations. Earn AZ-700.
4. Senior network engineer (3-5 years): Multi-cloud network strategy, leading network teams. AZ-305 + Cisco CCNP / AWS Networking.
5. Network architect (5+ years): Organization-wide network strategy, global network design. Salary range JPY 12-18M.
