NEW QUESTION 44
Your on-premises data center has 2 routers connected to your GCP 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 the same 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.
* The VPN logs have no-proposal-chosen lines when the VPNs are connecting.
* BGP session is not established between one on-premises router and the Cloud Router.
What is the most likely cause of this problem?
- A. You do not have a load balancer to load-balance the network traffic.
- B. BGP sessions are not established between both on-premises routers and the Cloud Router.
- C. One of the VPN sessions is configured incorrectly.
- D. A firewall is blocking the traffic across the second VPN connection.
Answer: A
NEW QUESTION 45
You are designing a shared VPC architecture. Your network and security team has strict controls over which routes are exposed between departments. Your Production and Staging departments can communicate with each other, but only via specific networks. You want to follow Google-recommended practices.
How should you design this topology?
- A. Create 2 shared VPCs within the shared VPC Host Project, and create a Cloud VPN/Cloud Router between them. Use Flexible Route Advertisement (FRA) to filter access between the specific networks.
- B. Create 2 shared VPCs within the shared VPC Host Project, and enable VPC peering between them. Use firewall rules to filter access between the specific networks.
- C. Create 1 VPC within the shared VPC Host Project, and share individual subnets with the Service Projects to filter access between the specific networks.

NEW QUESTION 46
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?
- A. Remove the -m flag from the gsutil command to enable single-threaded transfers.
- B. Tune TCP parameters on the on-premises servers.
- C. Compress files using utilities like tar to reduce the size of data being sent.
- D. Use the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET NAME].
Answer: D
NEW QUESTION 47
Your developer group works on a set of VM's frequently throughout the day. To save costs, you terminate the VM when it is not in use. However, you need to preserve the contents of the disk when the VM is terminated so users can resume where they left off when a new one is created.
What is the most cost-effective way to do? (Choose two)
- A. When not in use, only stop the instance instead of deleting it.
- B. Take a snapshot of the disk before terminating the VM.
- C. Back up the disk contents to Cloud Storage before deleting.
- D. Set the disk to no-auto-delete to preserve contents.
Answer: A,D
Explanation:
A (Correct Answer) - Set the disk to no-auto-delete to preserve contents. Setting your instance to not delete the root disk when deleting the instance will preserve the disk contents to attach to a new instance.
C (Correct Answer) - When not in use, only stop the instance instead of deleting it. Alternatively, you can merely stop the instance instead of deleting it, during which time you will not be billed for Machine Type usage (just disk storage).
B and D may work but are not suitable solutions since the VMs may need frequently stop and resume throughout the day.

NEW QUESTION 63
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?
- A. * Create a private cluster that uses VPC advanced routes.
* Set the pod and service ranges as /24.
* Set up a network proxy to access the master. - B. * Create a VPC-native GKE cluster using GKE-managed IP ranges.
* Set the pod IP range as /21 and service IP range as /24.
* Set up a network proxy to access the master. - C. * Create a VPC-native GKE cluster using user-managed IP ranges.
* Enable privateEndpoint on the cluster master.
* Set the pod and service ranges as /24.
* Set up a network proxy to access the master.
* Enable master authorized networks. - D. * Create a VPC-native GKE cluster using user-managed IP ranges.
* Enable a GKE cluster network policy, set the pod and service ranges as /24.
* Set up a network proxy to access the master.
* Enable master authorized networks.
Answer: C
Explanation:
Creating GKE private clusters with network proxies for controller access When you create a GKE private cluster with a private cluster controller endpoint, the cluster's controller node is inaccessible from the public internet, but it needs to be accessible for administration. By default, clusters can access the controller through its private endpoint, and authorized networks can be defined within the VPC network. To access the controller from on-premises or another VPC network, however, requires additional steps. This is because the VPC network that hosts the controller is owned by Google and cannot be accessed from resources connected through another VPC network peering connection, Cloud VPN or Cloud Interconnect. https://cloud.google.com/solutions/creating-kubernetes-engine-private-clusters-with-net-proxies
NEW QUESTION 64

- B. Set request-path to a specific URL used for health checking, and set proxy-header to PROXY_V1.
- C. Set request-path to a specific URL used for health checking, and set response to a string that the backend service will always return in the response body.
- D. Set proxy-header to the default value, and set host to include a custom host header that identifies the health check.

NEW QUESTION 65
Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead.
How should you design the topology?
- A. Create a Shared VPC Host Project and the respective Service Projects for each of the 3 separate departments.
- B. Create 3 separate VPCs, and use VPC peering to establish connectivity between the two appropriate VPCs.
- C. Create 3 separate VPCs, and use Cloud VPN to establish connectivity between the two appropriate VPCs.
- D. Create a single project, and deploy specific firewall rules. Use network tags to isolate access between the departments.
Answer: A
Explanation:
Use Shared VPC to connect to a common VPC network. Resources in those projects can communicate with each other securely and efficiently across project boundaries using internal IPs. You can manage shared network resources, such as subnets, routes, and firewalls, from a central host project, enabling you to apply and enforce consistent network policies across the projects.
With Shared VPC and IAM controls, you can separate network administration from project administration. This separation helps you implement the principle of least privilege. For example, a centralized network team can administer the network without having any permissions into the participating projects. Similarly, the project admins can manage their project resources without any permissions to manipulate the shared network.
