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.)
Your organization is developing a landing zone architecture with the following requirements:
There should be no communication between production and non-production environments.
Communication between applications within an environment may be necessary.
Network administrators should centrally manage all network resources, including subnets, routes, and firewall rules.
