Google Updated Professional-Cloud-Network-Engineer Exam Questions and Answers by oliwier

The correct answer is D because it meets the following requirements:

Each internal project has its own Google Cloud project, which can be easily created and deleted by Terraform using the google_project resource1.

Each internal project has its own Google Cloud project owner, which can be assigned by Terraform using the google_project_iam_member resource1.

The deployment is simple and the code is reusable with centralized management, because the Shared VPC allows you to connect multiple service projects to a single host project that contains the network resources2. This way, you can use Terraform modules to create and manage the network resources in the host project, and then reference them in the service projects3.

Option A is incorrect because it does not create separate Google Cloud projects for each internal project, which makes it harder to delete the infrastructure and assign project owners. Option B is incorrect because it does not create separate Google Cloud projects for each internal project, and also because it attaches the service projects to a Shared VPC, which is not recommended for short-lived projects2. Option C is incorrect because it does not use a Shared VPC, which means that each internal project has to create and manage its own network resources, which increases complexity and reduces reusability.

"TFTP is a UDP-based protocol. Servers listen on port 69 for the initial client-to-server packet to establish the TFTP session, then use a port above 1023 for all further packets during that session. Clients use ports above 1023" https://docstore.mik.ua/orelly/networking_2ndEd/fire/ch17_02.htm Besides, Google Cloud external TCP/UDP Network Load Balancing (after this referred to as Network Load Balancing) is a regional, non-proxied load balancer.

Explanation: Enabling VPC Flow Logs with sample_rate = 1.0 on the VM’s subnet will give detailed information about network traffic flowing to and from your VM. You can then query this data in Logs Explorer to check whether packets are leaving the VM and reaching the intended destination. This is a recommended practice for troubleshooting such network issues.
