9. Conclusion

Summary

This study guide has covered the five domains of the AZ-700 exam:

Phase 1: First Principles established the foundational mental models—connectivity vs. isolation vs. performance tradeoffs, routing decisions, and defense in depth. These principles help you reason through unfamiliar scenarios.

Phase 2: Core Infrastructure covered VNet design, IP addressing, DNS resolution, routing, and monitoring. Key takeaways: plan address spaces carefully (they're hard to change), understand VNet peering and gateway transit, and know when to use UDRs.

Phase 3: Connectivity Services addressed hybrid connectivity through VPN, ExpressRoute, and Virtual WAN. Remember: VPN is simple and cheap but internet-dependent; ExpressRoute provides private, high-bandwidth connectivity; Virtual WAN simplifies large-scale deployments.

Phase 4: Application Delivery distinguished between Layer 4 (Load Balancer) and Layer 7 (Application Gateway, Front Door) services. Choose based on routing requirements, global vs. regional scope, and security needs.

Phase 5: Private Access explained Private Link and Service Endpoints. Private Endpoints provide true private connectivity with DNS integration; Service Endpoints are simpler but limited to regional access.

Phase 6: Network Security covered NSGs, Azure Firewall, and WAF. Use NSGs for basic filtering, Azure Firewall for centralized FQDN/threat protection, and WAF for web application attacks.

Next Steps

  1. Hands-on practice — Deploy the services in a lab environment

  4. Review weak areas — Focus additional study on challenging topics

Confidence Check

Before scheduling your exam, verify you can:

  • Design VNet address spaces for multi-region deployments without overlap
  • Configure DNS for Private Endpoints in hybrid scenarios
  • Implement hub-spoke architecture with VPN or ExpressRoute and firewall
  • Choose appropriate load balancing service for given requirements
  • Troubleshoot connectivity using Network Watcher tools
  • Create NSG rules with service tags and ASGs
  • Deploy Azure Firewall with appropriate rule types
