Your company is working with a partner to provide a solution for a customer. Both your company and the partner organization are using GCP. There are applications in the partner's network that need access to some resources in your company's VPC. There is no CIDR overlap between the VPCs. Which two solutions can you implement to achieve the desired results without compromising the security? (Choose two.)
Your company is running out of network capacity to run a critical application in the on-premises data center. You want to migrate the application to GCP. You also want to ensure that the Security team does not lose their ability to monitor traffic to and from Compute Engine instances. Which two products should you incorporate into the solution? (Choose two.)
You are responsible for designing a new connectivity solution for your organization's enterprise network to access and use Google Workspace. You have an existing Shared VPC with Compute Engine instances in us-west1. Currently, you access Google Workspace via your service provider's internet access. You want to set up a direct connection between your network and Google. What should you do?
You recently deployed two network virtual appliances in us-central1. Your network appliances provide connectivity to your on-premises network, 10.0.0.0/8. You need to configure the routing for your Virtual Private Cloud (VPC). Your design must meet the following requirements: All access to your on-premises network must go through the network virtual appliances. Allow on-premises access in the event of a single network virtual appliance failure. Both network virtual appliances must be used simultaneously. Which method should you use to accomplish this?
You need to create a GKE cluster in an existing VPC that is accessible from on-premises. You must meet the following requirements: IP ranges for pods and services must be as small as possible. The nodes and the master must not be reachable from the internet. You must be able to use kubectl commands from on-premises subnets to manage the cluster. How should you create the GKE cluster?
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?
You have a storage bucket that contains the following objects: - folder-a/image-a-1.jpg - folder-a/image-a-2.jpg - folder-b/image-b-1.jpg - folder-b/image-b-2.jpg Cloud CDN is enabled on the storage bucket, and all four objects have been successfully cached. You want to remove the cached copies of all the objects with the prefix folder-a, using the minimum number of commands. What should you do?
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 and ensure the solution can scale. What should you do?
Your organization's security team recently discovered that there is a high risk of malicious activities originating from some of your VMs connected to the internet. These malicious activities are currently undetected when TLS communication is used. You must ensure that encrypted traffic to the internet is inspected. What should you do?
You are a network administrator at your company planning a migration to Google Cloud and you need to finish the migration as quickly as possible, To ease the transition, you decided to use the same architecture as your on-premises network' a hub-and-spoke model. Your on-premises architecture consists of over 50 spokes. Each spoke does not have connectivity to the other spokes, and all traffic IS sent through the hub for security reasons. You need to ensure that the Google Cloud architecture matches your on-premises architecture. You want to implement a solution that minimizes management overhead and cost, and uses default networking quotas and limits. What should you do?

You are configuring the final elements of a migration effort where resources have been moved from on-premises to Google Cloud. While reviewing the deployed architecture, you noticed that DNS resolution is failing when queries are being sent to the on-premises environment. You log in to a Compute Engine instance, try to resolve an on-premises hostname, and the query fails. DNS queries are not arriving at the on-premises DNS server. You need to use managed services to reconfigure Cloud DNS to resolve the DNS error. What should you do?

A.

Validate that the Compute Engine instances are using the Metadata Service IP address as their resolver. Configure an outbound forwarding zone for the on-premises domain pointing to the on-premises DNS server. Configure Cloud Router to advertise the Cloud DNS proxy range to the on-premises network.

Answers
A.

Validate that the Compute Engine instances are using the Metadata Service IP address as their resolver. Configure an outbound forwarding zone for the on-premises domain pointing to the on-premises DNS server. Configure Cloud Router to advertise the Cloud DNS proxy range to the on-premises network.

B.

Validate that there is network connectivity to the on-premises environment and that the Compute Engine instances can reach other on-premises resources. If errors persist, remove the VPC Network Peerings and recreate the peerings after validating the routes.

Answers
B.

Validate that there is network connectivity to the on-premises environment and that the Compute Engine instances can reach other on-premises resources. If errors persist, remove the VPC Network Peerings and recreate the peerings after validating the routes.

C.

Review the existing Cloud DNS zones, and validate that there is a route in the VPC directing traffic destined to the IP address of the DNS servers. Recreate the existing DNS forwarding zones to forward all queries to the on-premises DNS servers.

Answers
C.

Review the existing Cloud DNS zones, and validate that there is a route in the VPC directing traffic destined to the IP address of the DNS servers. Recreate the existing DNS forwarding zones to forward all queries to the on-premises DNS servers.

D.

Ensure that the operating systems of the Compute Engine instances are configured to send DNS queries to the on-premises DNS servers directly.

Answers
D.

Ensure that the operating systems of the Compute Engine instances are configured to send DNS queries to the on-premises DNS servers directly.

Suggested answer: A

Explanation:

To resolve DNS resolution issues for on-premises domains from Google Cloud, you should use Cloud DNS outbound forwarding zones. This setup forwards DNS requests for specific domains to on-premises DNS servers. Cloud Router is needed to advertise the range for the DNS proxy service back to the on-premises environment, ensuring that DNS queries from Compute Engine instances reach the on-premises DNS servers.
