Answer: Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone1-x and one VLAN attachment connected to metro1-zone2-x. Create a Cloud Router in region 2 with one VLAN attachment connected to metro2-zone1-x and one VLAN attachment to metro2-zone2-x.
To achieve geo-redundancy across two metropolitan areas (region1/metro1 and region2/metro2), Google recommends ensuring redundancy within each metro by distributing VLAN attachments across different zones. Each Cloud Router should be regional and configured with two VLAN attachments in separate zones of its paired metro. Option D correctly configures the Cloud Routers in region1 and region2 with two VLAN attachments each, spread across their respective metro's zones (metro1-zone1 and metro1-zone2 for region1, metro2-zone1 and metro2-zone2 for region2). This setup ensures intra-metro redundancy (via multiple zones) and geo-redundancy (via separate metros), aligning with Google's best practices.
