Quiz - Hybrid Load Balancing and Traffic Management

Graded Assignment

1. When you use the internal IP address of the forwarding rule to specify an internal Network Load Balancer next hop, the load balancer can only be:

  • In the same VPC network as the next hop route.
  • In the same VPC network as the next hop route or in a peered VPC network. ✅
  • In the same subnet as the next hop route or a Shared VPC network.
  • In the same subnet as the next hop route.

Explanation:
When configuring a custom static route that uses an internal forwarding rule (used by an internal passthrough Network Load Balancer) as a next hop, the forwarding rule must be in the same VPC or a VPC that’s peered with the one where the route is defined.

2. Where would you configure traffic management for a load balancer?

  • In the load balancer backend
  • In the load descriptor
  • In the URL map ✅
  • In the load balancer frontend

Explanation:
A URL map is used in HTTP(S) and TCP Proxy load balancers to define routing rules. It controls how requests are forwarded to different backend services, based on URL paths, hostnames, and other policies.

3. You can use hybrid load balancing to connect these environments:

  • Google Cloud and on-premises
  • Google Cloud, other public clouds, and on-premises ✅
  • Google Cloud and AWS
  • Google Cloud, AWS, and on-premises

Explanation:
This includes AWS, Azure, on-prem data centers, and other environments. Hybrid load balancing supports traffic distribution across Google Cloud and external endpoints via Cloud VPN, Interconnect, and Traffic Director.
