You are designing a hybrid cloud environment for your organization. Your Google Cloud environment is interconnected with your on-premises network using Cloud HA VPN and Cloud Router. The Cloud Router is configured with the default settings. Your on-premises DNS server is located at 192.168.20.88 and is protected by a firewall, and your Compute Engine resources are located at 10.204.0.0/24. Your Compute Engine resources need to resolve on-premises private hostnames using the domain corp.altostrat.com while still resolving Google Cloud hostnames. You want to follow Google-recommended practices. What should you do?
A. 1. Create a private forwarding zone in Cloud DNS for ‘corp.altostrat.com’ called corp-altostrat-com that points to 192.168.20.88.
2. Configure your on-premises firewall to accept traffic from 10.204.0.0/24.
3. Set a custom route advertisement on the Cloud Router for 10.204.0.0/24
B. 1. Create a private forwarding zone in Cloud DNS for ‘corp.altostrat.com’ called corp-altostrat-com that points to 192.168 20.88.
2. Configure your on-premises firewall to accept traffic from 35.199.192.0/19
3. Set a custom route advertisement on the Cloud Router for 35.199.192.0/19.
C. 1. Create a private forwarding zone in Cloud DNS for ‘corp .altostrat.com’ called corp-altostrat-com that points to 192.168.20.88.
2. Configure your on-premises firewall to accept traffic from 10.204.0.0/24.
3. Modify the /etc/resolv conf file on your Compute Engine instances to point to 192.168.20 88
D. 1. Create a private zone in Cloud DNS for ‘corp altostrat.com’ called corp-altostrat-com.
2. Configure DNS Server Policies and create a policy with Alternate DNS servers to 192.168.20.88.
3. Configure your on-premises firewall to accept traffic from 35.199.192.0/19.
4. Set a custom route advertisement on the Cloud Router for 35.199.192.0/19.
