You need to accomplish this in the most cost-effective manner possible. What should you do?

2. Add an additional Cloud Interconnect VLAN attachment in the us-east1 region, and configure a Cloud Router in us-east1.
B. 1. Configure your VPC routing in global mode.
2. Add an additional Cloud Interconnect VLAN attachment in the us-east1 region, and configure a Cloud Router in us-east1.
C. 1. Configure your VPC routing in global mode.
2. Add an additional Cloud Interconnect VLAN attachment in the us-west2 region, and configure a Cloud Router in us-west2.
D. 1. Configure your VPC routing in regional mode.

Selected Answer: C

The most suitable option for high availability and cost-effectiveness would be Option C. Configuring global routing ensures that in case of failure in one region (e.g., us-east1), your traffic can be routed through another region (e.g., us-west2), maintaining access to your VPC subnets. This approach balances cost and provides a high-availability design. Thus, the correct answer is: C.

Answer is C: If using VPC regional routing - only dynamics routes for THAT region only! If the region goes down, per the question - you have no connectivity. Must be global routing and VLAN attachment in another region

Selected Answer: B

Answer should be B. C does not provide SLA guarantees, B does with 99.9%, if you of course connect to a different zone in the metro.

if a region goes down, you still have access to all your other Virtual Private Cloud (VPC) subnets. B is not the answer
