Question 6
You are designing a security-focused network architecture on Google Cloud. Your company has deployed a central inspection VPC that contains a fleet of Cloud Next Generation Firewall (NGFW) appliances. The inspection VPC has a default route with next hop pointing to the passthrough Network Load Balancer with NGFW appliances as backends.
You also have two application VPCs (App-A and App-B) that are not allowed to directly communicate with each other, nor do they have a default route in their VPC. You need to ensure that all traffic originating from App-A and App-B are forced through the inspection VPC to be analyzed by the Cloud NGFW appliances.

Question 8
You are establishing a high-throughput, highly reliable, and private network link for a multinational corporation between its on-premises data center in Frankfurt. It is located within a Google- supported co-location facility, and its Google Cloud VPC in the europe-west3 region. You need a connection that supports large-scale data synchronization and real-time application traffic with a bandwidth of 10 Gbps or more. What should you do?

Question 9
You have two VPCs: VPC A in Project A and VPC B in Project B. The VPCs are peered, and each VPC has VM instances in four zones. You are using the Network Intelligence Center Performance Dashboard to investigate the packet loss for traffic flows that start in VPC A and terminate in VPC B. You need the reported packet loss metric to have at least a 90% confidence level. What should you do?

Question 10
Your organization, TerramEarth, is launching a global application to manage credit card payments. There are some client VMs inside the same VPC as the application that need to access this application privately. Due to compliance requirements, the internal clients cannot use the global external IP address of the application. Currently, Cloud DNS only resolves myglobalapp.terramearth.com to the public IP address with a public zone. The clients will need to reach myglobalapp.example.com, without using its external IP address. You need to configure Cloud DNS to follow this requirement while following Google-recommended practices. What should you do?

Question 11
You are establishing a hybrid connectivity solution between your on-premises data center and a Google Cloud VPC network using Cloud Interconnect. The connection must automatically adapt to network topology changes and provide high availability. You need to ensure that routes from your on-premises network are dynamically advertised to your Google Cloud VPC. You also need to ensure that routes from your Google Cloud VPC are dynamically advertised back to your on- premises routers. What should you do?

Question 12
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.
