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.)
You have just deployed your infrastructure on Google Cloud. You now need to configure the DNS to meet the following requirements:
Your on-premises resources should resolve your Google Cloud zones.
Your Google Cloud resources should resolve your on-premises zones.
You need the ability to resolve ''. internal'' zones provisioned by Google Cloud.
What should you do?
You have the following routing design. You discover that Compute Engine instances in Subnet-2 in the asia-southeast1 region cannot communicate with compute resources on-premises. What should you do?

Your organization uses a hub-and-spoke architecture with critical Compute Engine instances in your Virtual Private Clouds (VPCs). You are responsible for the design of Cloud DNS in Google Cloud. You need to be able to resolve Cloud DNS private zones from your on-premises data center and enable on-premises name resolution from your hub-and-spoke VPC design. What should you do?
You need to restrict access to your Google Cloud load-balanced application so that only specific IP addresses can connect.
