NEW QUESTION # 35
You are migrating to Cloud DNS and want to import your BIND zone file.
Which command should you use?
gcloud dns record-sets import ZONE_FILE --zone MANAGED_ZONE
- A. MANAGED_ZONE
gcloud dns record-sets import ZONE_FILE --zone-file-format --zone MANAGED_ZONE - B. gcloud dns record-sets import ZONE_FILE --replace-origin-ns --zone
- C. MANAGED_ZONE
- D. gcloud dns record-sets import ZONE_FILE --delete-all-existing --zone
Answer: D
Explanation:
Once you have the exported file from your other provider, you can use the gcloud dns record-sets import command to import it into your managed zone.
To import record-sets, you use the dns record-sets import command. The --zone-file-format flag tells importto expect a BIND zone formatted file. If you omit this flag, import expects a YAML-formatted records file.

NEW QUESTION # 38
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. Use Cloud DNS to create A records of all VMs and resources across all projects in both organizations.
- B. Connect VPCs in both organizations using Cloud VPN together with Cloud Router.
- C. Provision Cloud Interconnect to connect both organizations together.
- D. Create a third organization with a new host project, and attach all projects from your company and Altostrat to it using shared VPC.
- E. Set up some variant of DNS forwarding and zone transfers in each organization.
Answer: A,C
NEW QUESTION # 39
You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone.
What should you do?
- A. Update the TTL for the zone.
- B. Transfer ownership of the domain to a new registar.
Before disabling DNSSEC for a managed zone you want to use, you must deactivate DNSSEC at your domain registrar to ensure that DNSSEC-validating resolvers can still resolve names in the zone. - C. Set the zone to the TRANSFER state.
- D. Disable DNSSEC at your domain registar.
Answer: D

NEW QUESTION # 48
Your on-premises data center has 2 routers connected to your Google Cloud environment through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.
