| Design and implement core networking infrastructure | IP addressing and subnetting for gateways, private endpoints, firewalls and Bastion, subnet delegation, public IP prefixes and bring-your-own-IP, name resolution with public and private DNS zones plus Azure DNS Private Resolver, VNet peering and gateway transit, UDRs and forced tunneling, Azure Virtual Network Manager, Azure Route Server, NAT Gateway, and monitoring with Network Watcher, Azure Monitor for Networks, DDoS protection and Defender for Cloud attack path analysis. | 25 to 30% |
| Design, implement, and manage connectivity services | The hybrid domain. Site-to-site VPNs including HA designs, gateway SKUs, policy-based vs route-based decisions and IPsec/IKE policies, point-to-site VPNs with tunnel types, RADIUS and Entra ID authentication, ExpressRoute end to end: connectivity models, SKUs and tiers, Global Reach, FastPath, ExpressRoute Direct, private vs Microsoft peering, encryption and Bidirectional Forwarding Detection, plus Virtual WAN architectures with hubs, gateway scale units and third-party NVA integration. | 20 to 25% |
| Design and implement application delivery services | Azure Load Balancer SKUs, public vs internal and regional vs cross-region choices, Gateway Load Balancer, inbound NAT and explicit outbound SNAT rules, Traffic Manager, Application Gateway with backend pools, health probes, listeners, routing rules, TLS and rewrite rule sets, and Azure Front Door with tiers, TLS termination, caching, and Private Link origins. | 15 to 20% |
| Design and implement Azure network security services | NSGs and application security groups, inbound and outbound rules, virtual network flow logs and IP flow verification, Azure Firewall SKU selection, rules and Firewall Manager policies, secured hubs inside Virtual WAN, and WAF deployments in detection or prevention mode with rule sets on both Front Door and Application Gateway. | 15 to 20% |
| Design and implement private access to Azure services | The smallest domain, and a giveaway if you know it: planning and creating private endpoints, building a Private Link service, DNS integration for Private Link, reaching it from on-premises clients, and when a service endpoint with policies is the right call instead. | 10 to 15% |
