Related Certifications

•AZ-104 Azure Administrator

•AZ-305 Azure Solutions Architect Expert

Key Exam Topics

•VNet: isolated network; subnets; each resource gets private IP from subnet CIDR

•NSG (Network Security Group): stateful, layer 4 filtering; apply to subnet or NIC

•VNet Peering: non-transitive; works global (cross-region); must add routes if needed

•Azure Firewall vs NSG: Firewall = centralized L3-L7; NSG = local L4 only

•Private Endpoint vs Service Endpoint: Private = real private IP for service; Service = route optimization only

•VPN Gateway: site-to-site (IPSec) or point-to-site (VPN client); up to 10 Gbps

•ExpressRoute: private dedicated circuit (not over internet); 50 Mbps to 100 Gbps

Must-Know CLI Commands

Exam Tips

•VNet peering: bidirectional — must create peering in BOTH VNets

•Hub-spoke: hub VNet with Azure Firewall + shared services; spokes peer to hub

•Private DNS zones: required for private endpoints to resolve service FQDNs to private IPs

•Azure DDoS Protection Standard: $2,700/month but covers all public IPs in VNet
