Google Cloud Professional Cloud Network Engineer — Question 83

You are configuring your Google Cloud environment to connect to your on-premises network. Your configuration must be able to reach Cloud Storage APIs and your Google Kubernetes Engine nodes across your private Cloud Interconnect network. You have already configured a Cloud Router with your Interconnect VLAN attachments. You now need to set up the appropriate router advertisement configuration on the Cloud Router. What should you do?

Answer options

• A. Configure the route advertisement to the default setting.
• B. On the on-premises router, configure a static route for the storage API virtual IP address which points to the Cloud Router's link-local IP address.
• C. Configure the route advertisement to the custom setting, and manually add prefix 199.36.153.8/30 to the list of advertisements. Leave all other options as their default settings.
• D. Configure the route advertisement to the custom setting, and manually add prefix 199.36.153.8/30 to the list of advertisements. Advertise all visible subnets to the Cloud Router.

Correct answer: D

Explanation

The correct answer is D because it ensures that all relevant subnets are advertised to the Cloud Router, allowing full connectivity to both Cloud Storage APIs and the Google Kubernetes Engine nodes. Option A is incorrect as it does not customize the advertisement settings needed for proper routing. Option B fails to address the need for subnet visibility, and option C does not include advertising all visible subnets, which is necessary for optimal connectivity.
