You are designing a Partner Interconnect hybrid cloud connectivity solution with geo-redundancy across two metropolitan areas. You want to follow Google-recommended practices to set up the following region/metro pairs:
• (region 1/metro 1)
• (region 2/metro 2)
What should you do?

A. Create a Cloud Router in region 1 with two VLAN attachments connected to metro1-zone1-x.
Create a Cloud Router in region 2 with two VLAN attachments connected to metro1-zone2-x. B. Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone1-x.
Create a Cloud Router in region 2 with two VLAN attachments connected to metro2-zone2-x. C. Create a Cloud Router in region 1 with one VLAN attachment connected to metro1-zone2-x.
Create a Cloud Router in region 2 with one VLAN attachment connected to metro2-zone2-x. D. 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.
