NEW QUESTION 14
You are migrating to Cloud DNS and want to import your BIND zone file.
Which command should you use?
- A. gcloud dns record-sets import ZONE_FILE --zone-file-format --zone MANAGED_ZONE
- B. gcloud dns record-sets import ZONE_FILE --delete-all-existing --zone MANAGED ZONE
- C. gcloud dns record-sets import ZONE_FILE --zone MANAGED_ZONE
- D. gcloud dns record-sets import ZONE_FILE --replace-origin-ns --zone MANAGED_ZONE
Answer: A
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 19
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.
During troubleshooting you find:
- Each on-premises router is configured with a unique ASN. ?Each on-
premises router is configured with the same routes and priorities.
- Both on-premises routers are configured with a VPN connected to a
single Cloud Router.
- BGP sessions are established between both on-premises routers and the Cloud Router.
- Only 1 of the on-premises router's routes are being added to the
routing table.
What is the most likely cause of this problem?
- A. A firewall is blocking the traffic across the second VPN connection.
- B. The ASNs being used on the on-premises routers are different.
- C. You do not have a load balancer to load-balance the network traffic.
- D. The on-premises routers are configured with the same routes.

NEW QUESTION 20
Your end users are located in close proximity to us-east1 and europe-west1. Their workloads need to communicate with each other. You want to minimize cost and increase network efficiency.
How should you design this topology?
- A. Create 1 VPC with 2 regional subnets. Deploy workloads in these subnets and have them communicate using private RFC1918 IP addresses.
- B. Create 2 VPCs, each with their own regions and individual subnets. Create 2 VPN gateways to establish connectivity between these regions.
- C. Create 1 VPC with 2 regional subnets. Create a global load balancer to establish connectivity between the regions.
- D. Create 2 VPCs, each with their own region and individual subnets. Use external IP addresses on the instances to establish connectivity between these regions.
Answer: A
Explanation:
VPC Network Peering enables you to peer VPC networks so that workloads in different VPC networks can communicate in private RFC 1918 space. Traffic stays within Google's network and doesn't traverse the public internet.

NEW QUESTION 34
You have configured Cloud CDN using HTTP(S) load balancing as the origin for cacheable content. Compression is configured on the web servers, but responses served by Cloud CDN are not compressed.
What is the most likely cause of the problem?
- A. The web servers behind the load balancer are configured with different compression types.
- B. You have not configured compression in Cloud CDN.
- C. You have configured the web servers and Cloud CDN with different compression types.
- D. You have to configure the web servers to compress responses even if the request has a Via header.
Answer: D
Explanation:
If responses served by Cloud CDN are not compressed but should be, check that the web server software running on your instances is configured to compress responses. By default, some web server software will automatically disable compression for requests that include a Via header. The presence of a Via header indicates the request was forwarded by a proxy. HTTP proxies such as HTTP(S) load balancing add a Via header to each request as required by the HTTP specification.
To enable compression, you may have to override your web server's default configuration to tell it to compress responses even if the request had a Via header.
