Your company just completed the acquisition of Altostrat (a current GCP customer). Each company has a separate organization in GCP and has implemented a custom DNS solution. Each organization will retain its current domain and host names until after a full transition and architectural review is done in one year.
These are the assumptions for both GCP environments.
– Each organization has enabled full connectivity between all of its projects by using Shared VPC.
– Both organizations strictly use the 10.0.0.0/8 address space for their instances, except for bastion hosts (for accessing the instances) and load balancers for serving web traffic.
– There are no prefix overlaps between the two organizations.
– Both organizations already have firewall rules that allow all inbound and outbound traffic from the 10.0.0.0/8 address space.
– Neither organization has Interconnects to their on-premises environment.
You want to integrate networking and DNS infrastructure of both organizations as quickly as possible and with minimal downtime.
Which two steps should you take? (Choose two.)
A. Provision Cloud Interconnect to connect both organizations together.
B. Set up some variant of DNS forwarding and zone transfers in each organization.
C. Connect VPCs in both organizations using Cloud VPN together with Cloud Router.
D. Use Cloud DNS to create A records of all VMs and resources across all projects in both organizations.
E. Create a third organization with a new host project, and attach all projects from your company and Altostrat to it using shared VPC.

B C
Connecting two VPC could be done with cloud VPN. So C is correct
to enable two VPC resolve each other name there are two major approach
if you use cloud DNS you should go for DNS Peering
If you use custom DNS Solution use zone transfer and forwarding so B is Correct also.
B and C seems to be correct.
