Topic #: 4

[All Professional Cloud Network Engineer Questions]

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?

AUse 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

BUse global 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

CUse regional routing. Set the us-east1 Cloud Router to a base priority of 1000, and set the us-west1 Cloud Router to a base priority of 1

DUse global routing. Set the us-east1 Cloud Router to a base priority of 1000, and set the us-west1 Cloud Router to a base priority of 1

I think we should go with global routing. It seems like the best option for ensuring high availability in case of a failure.

I see your point, Jesusita. Global routing might provide a more efficient failover path.

But wouldn't using global routing with a base priority of 1000 for us-east1 be a better option?

I agree with Antonette. Setting a higher base priority for us-east1 Cloud Router makes sense for failover.

I think we should use regional routing and set the us-east1 Cloud Router to a base priority of 1000.

Hmm, I can see the rationale behind both options. It's a tough decision.

I still think regional routing with a base priority of 100 for us-east1 is the way to go.

I see your point, Erasmo. Global routing could potentially provide more flexibility.

But wouldn't it be better to use global routing for this scenario?

I think we should use regional routing to set up the failover path.

Ah, I see. So if we set the us-east1 Cloud Router to a higher MED value, like 1000, and the us-west1 Cloud Router to a lower MED value, like 1, that should make the us-west1 connection the preferred route. And if it goes down, the traffic will failover to us-east1.

I think the key here is understanding the MED values and how they impact route selection. The MED is the 'Multi-Exit Discriminator', which is used to prefer certain routes over others.

Okay, let's break this down. We need to configure a high availability failover path, and the default traffic should flow through the us-west1 connection. If that's down, we want it to reroute to us-east1.

B) Use global 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

Hmm, this question seems a bit tricky. I'm not entirely sure about the differences between regional and global routing, and how the MED values would affect the failover path.
