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. Set up some variant of DNS forwarding and zone transfers in each organization.
  • B. Use Cloud DNS to create A records of all VMs and resources across all projects in both organizations.
  • C. Provision Cloud Interconnect to connect both organizations together.
  • D. Connect VPCs in both organizations using Cloud VPN together with Cloud Router.
  • E. Create a third organization with a new host project, and attach all projects from your company and Altostrat to it using shared VPC.

Correct Answer: A,D  🗳️

Explanation: Only visible for ExamcollectionPass members. You can sign-up / login (it's free).

Your organization uses Google Cloud's Network Connectivity Center. One of the VPC spokes contains subnet-corp-prod (10.10.1.0/24) and subnet-corp-test (192.168.1.0/24). You need to ensure that only the subnet-corp-prod range is advertised to the Network Connectivity Center hub, even if new subnets are created in the VPC. You want to use the most direct and precise method to control route advertisements from this spoke. What should you do?

  • A. Create a VPC firewall rule with a DENY action for the 192.168.1.0/24 range.
  • B. Add 192.168.1.0/24 to the exclude export ranges filter in the VPC spoke configuration.
  • C. Create a custom static route in the Network Connectivity Center hub with the next hop as the VPC spoke for the 10.10.1.0/24 range.
  • D. Set the include export ranges filter to 10.10.1.0/24 in the VPC Spoke configuration, and ensure no other ranges are included.

Your organization has approximately 100 teams that need to manage their own environments. A central team must manage the network. You need to design a landing zone that provides separate projects for each team. You must also make sure the solution can scale. What should you do?
