Google Cloud Professional Cloud Network Engineer — Question 244

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?

Answer options

• 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.

Correct answer: D

Explanation

Option D is correct because it provides the necessary geo-redundancy by ensuring each region has connections to both zones, which enhances reliability and failover capabilities. The other options do not meet this requirement; they either lack sufficient VLAN connections or do not utilize both available zones effectively.
