Question 30

Question

Your company has a Virtual Private Cloud (VPC) with two Dedicated Interconnect connections in two
different regions: us-west1 and us-east1. Each Dedicated Interconnect connection is attached to a
Cloud Router in its respective region by a VLAN attachment. You need to configure a high availability
failover path. By default, all ingress traffic from the on-premises environment should flow to the VPC
using the us-west1 connection. If us-west1 is unavailable, you want traffic to be rerouted to us-east1.
How should you configure the multi-exit discriminator (MED) values to enable this failover path?

Accepted Answer

Use regional routing. Set the us-east1 Cloud Router to a base priority of 100, and set the us-west1
Cloud Router to a base priority of 1

Luke E. · Answer

A . Had something like this in a mock, regional routing plus those specific MED values for primary/secondary is what worked.

Drew · Answer

Its A but if they wanted global routing instead of regional, that would flip things toward D.

Amelia · Answer

A is correct here, not D. Regional routing plus MED values (1 for west, 100 for east) matches the failover requirement.

Aaron · Answer

D . Global routing looks tempting for multi-region but I think that's a common trap here.

Olivia G. · Answer

A , not D. Some people get tripped up by global vs regional, but for failover per region the MED values in A make sense.
