Your company's current network deployment consists of:
- One physical branch office in CITY_A.
- One physical branch office in CITY_B.
- One VPC with two compute instances (SDWAN_ONE, SDWAN_TWO) that act as SDWAN hubs for the two branch offices and provide applications running in the branch offices access to the databases deployed in the VPC. The databases are deployed on compute instances.
The CITY_A branch office has an SDWAN tunnel to the SDWAN_ONE compute instance. The CITY_B branch office has an SDWAN tunnel to the SDWAN_TWO compute instance. All tunnels run over the public internet.
You are notified that the applications in the CITY_A branch office are excessively slow. You need to determine if this behavior is network related. You must leverage a procedure that requires the least amount of setup effort and cost.
What should you do?

You have provisioned a Dedicated Interconnect connection of 20 Gbps with a VLAN attachment of 10 Gbps. You recently noticed a steady increase in ingress traffic on the Interconnect connection from the on-premises data center. You need to ensure that your end users can achieve the full 20 Gbps throughput as quickly as possible. Which two methods can you use to accomplish this? (Choose two.)

Your company has a web application, app.example.com, hosted on a Compute Engine instance within a Google Cloud VPC. You need to configure DNS so that employees inside the VPC resolve app.example.com to its private IP address, while external users on the internet resolve the same hostname to a public IP address managed by a global external HTTPS Application Load Balancer. Your solution needs to follow Google-recommended practices. What should you do?

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?

Your company runs shop.example.com. a global e-commerce application deployed in three Google Cloud regions: us-central1, europe-west1, and asia-east1. Each regional deployment is served by a regional external Application Load Balancer. You need to configure Cloud DNS to route users to the regional load balancer closest to their geographic location to minimize latency.
