1Designing and planning a Google Cloud VPC network

• 1.1Overall network design and VPC design

  Understand network tiers (Premium/Standard), high availability/failover/DR/scale, DNS topology, load balancer selection, Shared VPC vs standalone, VPC peering and Network Connectivity Center, IP address management (subnets/IPv6/PUPI/non-RFC1918/Private NAT), global/regional dynamic routing, MTU, and IAM roles suited to network designs.

• 1.2Hybrid/multicloud and GKE design

  Understand hybrid connectivity (Dedicated/Partner Interconnect, Cloud VPN, SD-WAN), multicloud connectivity (Cloud VPN, Cross-Cloud Interconnect), Direct Peering vs Verified Peering Provider, cross-region HA/DR, hybrid DNS topology (forwarding/inbound policies/DNS peering), interconnect encryption (MACsec/HA VPN over Interconnect), and GKE network design (VPC-native, secondary ranges, private clusters, control-plane access).
