The IP address of the instance on the remote side of the VPN tunnel

Q60. You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection.
What should you do on your on-premises servers?

Tune TCP parameters on the on-premises servers.

Compress files using utilities like tar to reduce the size of data being sent.

Remove the -m flag from the gsutil command to enable single-threaded transfers.

Use the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET_NAME].

Q61. You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN.
What should you do?

Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.

Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.

Add a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.

– 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?

Add an appropriate lifecycle rule on the storage bucket.

Issue a cache invalidation command with pattern /folder-a/*.

Make sure that all the objects with prefix folder-a are not shared publicly.

Disable Cloud CDN on the storage bucket. Wait 90 seconds. Re-enable Cloud CDN on the storage bucket.

Q64. You need to create a new VPC network that allows instances to have IP addresses in both the 10.1.1.0/24 network and the 172.16.45.0/24 network.
What should you do?

Configure global load balancing to point 172.16.45.0/24 to the correct instance.

Create unique DNS records for each service that sends traffic to the desired IP address.

Configure an alias-IP range of 172.16.45.0/24 on the virtual instances within the VPC subnet of 10.1.1.0/24.

Use VPC peering to allow traffic to route between the 10.1.0.0/24 network and the 172.16.45.0/24 network.

Q65. Your organization recently re-architected your cloud environment to use Network Connectivity Center. However, an error occurred when you tried to add a new VPC named vpc-dev as a spoke. The error indicated that there was an issue with an existing spoke and the IP space of a VPC named vpc-pre-prod. You must complete the migration quickly and efficiently. What should you do?

Remove the conflicting VPC spoke for vpc-pre-prod from the set of VPC spokes in Network Connectivity Center. Add the VPC spoke for vpc-dev. Add the previously removed vpc-pre-prod as a VPC spoke.

Create a managed instance group for each region, select Single zone for the location, and manually distribute instances across the zones in that region.

Create an unmanaged instance group in a single zone, and then create an HTTP load balancer for the instance group.

Create an unmanaged instance group for each zone, and manually distribute the instances across the desired zones.

Q67. You recently configured Google Cloud Armor security policies to manage traffic to your application. You discover that Google Cloud Armor is incorrectly blocking some traffic to your application. You need to identity the web application firewall (WAF) rule that is incorrectly blocking traffic. What should you do?

Enable firewall logs, and view the logs in Firewall Insights.

Enable HTTP(S) Load Balancing logging with sampling rate equal to 1, and view the logs in Cloud Logging.

Enable VPC Flow Logs, and view the logs in Cloud Logging.

Enable Google Cloud Armor audit logs, and view the logs on the Activity page in the Google Cloud Console.

Q68. In your Google Cloud organization, you have two folders: Dev and Prod. You want a scalable and consistent way to enforce the following firewall rules for all virtual machines (VMs) with minimal cost:
Port 8080 should always be open for VMs in the projects in the Dev folder.
Any traffic to port 8080 should be denied for all VMs in your projects in the Prod folder.
What should you do?

Create and associate a firewall policy with the Dev folder with a rule to open port 8080. Create and associate a firewall policy with the Prod folder with a rule to deny traffic to port 8080.

Create a Shared VPC for the Dev projects and a Shared VPC for the Prod projects. Create a VPC firewall rule to open port 8080 in the Shared VPC for Dev. Create a firewall rule to deny traffic to port 8080 in the Shared VPC for Prod. Deploy VMs to those Shared VPCs.

In all VPCs for the Dev projects, create a VPC firewall rule to open port 8080. In all VPCs for the Prod projects, create a VPC firewall rule to deny traffic to port 8080.

Use Anthos Config Connector to enforce a security policy to open port 8080 on the Dev VMs and deny traffic to port 8080 on the Prod VMs.

Configure a forwarding rule on the existing load balancer for the application tier.

Configure equal cost multi-path routing on the application servers.

Configure a new internal HTTP(S) load balancer for the application tier.

Configure a URL map on the existing load balancer to route traffic to the application tier.

Q74. You have several microservices running in a private subnet in an existing Virtual Private Cloud (VPC). You need to create additional serverless services that use Cloud Run and Cloud Functions to access the microservices. The network traffic volume between your serverless services and private microservices is low. However, each serverless service must be able to communicate with any of your microservices. You want to implement a solution that minimizes cost. What should you do?

Deploy your serverless services to the serverless VPC. Peer the serverless service VPC to the existing VPC. Configure firewall rules to allow traffic between the serverless services and your existing microservices.

Create a serverless VPC access connector for each serverless service. Configure the connectors to allow traffic between the serverless services and your existing microservices.

Deploy your serverless services to the existing VPC. Configure firewall rules to allow traffic between the serverless services and your existing microservices.

Q76. You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN.
What should you do?

Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.

Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.

Q77. You are using a third-party next-generation firewall to inspect traffic. You created a custom route of 0.0.0.0/0 to route egress traffic to the firewall. You want to allow your VPC instances without public IP addresses to access the BigQuery and Cloud Pub/Sub APIs, without sending the traffic through the firewall.
Which two actions should you take? (Choose two.)

Turn on Private Google Access at the subnet level.

Turn on Private Google Access at the VPC level.

Turn on Private Services Access at the VPC level.

Create a set of custom static routes to send traffic to the external IP addresses of Google APIs and services via the default internet gateway.

Create a set of custom static routes to send traffic to the internal IP addresses of Google APIs and services via the default internet gateway.

Q78. 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?

The on-premises routers are configured with the same routes.

A firewall is blocking the traffic across the second VPN connection.

You do not have a load balancer to load-balance the network traffic.

The ASNs being used on the on-premises routers are different.

Q79. You have a storage bucket that contains two objects. Cloud CDN is enabled on the bucket, and both objects have been successfully cached. Now you want to make sure that one of the two objects will not be cached anymore, and will always be served to the internet directly from the origin.
What should you do?

Ensure that the object you don’t want to be cached anymore is not shared publicly.

Create a new storage bucket, and move the object you don’t want to be checked anymore inside it. Then edit the bucket setting and enable the privateattribute.

Add an appropriate lifecycle rule on the storage bucket containing the two objects.

Add a Cache-Controlentry with value private to the metadata of the object you don’t want to be cached anymore. Invalidate all the previously cached copies.

Q80. You need to enable Private Google Access for use by some subnets within your Virtual Private Cloud (VPC). Your security team set up the VPC to send all internet-bound traffic back to the on- premises data center for inspection before egressing to the internet, and is also implementing VPC Service Controls in the environment for API-level security control. You have already enabled the subnets for Private Google Access. What configuration changes should you make to enable Private Google Access while adhering to your security team’s requirements?

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google’s restricted API address range.
Create a custom route that points Google’s restricted API address range to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google’s restricted API address range.
Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record painting to Google’s private AP address range.
Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Google’s private API address range.
Create a custom route that points Google’s private API address range to the default internet gateway as the next hop.

Q81. You just finished your company’s migration to Google Cloud and configured an architecture with 3 Virtual Private Cloud (VPC) networks: one for Sales, one for Finance, and one for Engineering. Every VPC contains over 100 Compute Engine instances, and now developers using instances in the Sales VPC and the Finance VPC require private connectivity between each other. You need to allow communication between Sales and Finance without compromising performance or security. What should you do?
