質問 # 81
You built a web application with several containerized microservices. You want to run those microservices on Cloud Run. You must also ensure that the services are highly available to your customers with low latency. What should you do?

A. Deploy the Cloud Run services to multiple availability zones. Create Cloud Endpoints that point to the services. Create a global HTTPS load balancer, and attach the Cloud Endpoints to its backend
B. Deploy the Cloud Run services to multiple availability zones. Create a global TCP load balancer. Add the Cloud Run endpoints to its backend service.
C. Deploy the Cloud Run services to multiple regions. Create serverless network endpoint groups (NEGs) that point to the services. Create a global HTTPS load balancer, and attach the serverless NEGs as backend services of the load balancer.
D. Deploy the Cloud Run services to multiple regions. Configure a round-robin A record in Cloud DNS.

正解：C

質問 # 82
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. A firewall is blocking the traffic across the second VPN connection.
B. One of the VPN sessions is configured incorrectly.
C. You do not have a load balancer to load-balance the network traffic.
D. BGP sessions are not established between both on-premises routers and the Cloud Router.

正解：B

解説：
If the VPN logs show a no-proposal-chosen error, this error indicates that Cloud VPN and your peer VPN gateway were unable to agree on a set of ciphers. For IKEv1, the set of ciphers must match exactly. For IKEv2, there must be at least one common cipher proposed by each gateway. Make sure that you use supported ciphers to configure your peer VPN gateway. https://cloud.google.com/network-connectivity/docs

質問 # 83
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?

A. Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.
B. 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.
C. Add a second Cloud VPN gateway in a different region than the existing VPN gateway. Create a new tunnel on the second Cloud VPN gateway that forwards the same IP range, but points to the existing on-premises VPN gateway IP address.
D. Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.

正解：B

質問 # 84
You ate planning to use Terraform to deploy the Google Cloud infrastructure for your company, The design must meet the following requirements
* Each Google Cloud project must represent an Internal project that your team Will work on
* After an Internal project is finished, the infrastructure must be deleted
* Each Internal project must have Its own Google Cloud project owner to manage the Google Cloud resources.
* You have 10-100 projects deployed at a time
While you are writing the Terraform code, you need to ensure that the deployment is simple and the code is reusable With centralized management What should you do?

A. Create a Single project and Single VPC for each internal project
B. Create a Shared VPC and service project for each internal project
C. Create a Single project and additional VPCs for each internal project
D. Create a Single Shared VPC and attach each Google Cloud project as a service project

正解：B

解説：
The correct answer is D because it meets the following requirements:
Each internal project has its own Google Cloud project, which can be easily created and deleted by Terraform using the google_project resource1.
Each internal project has its own Google Cloud project owner, which can be assigned by Terraform using the google_project_iam_member resource1.
The deployment is simple and the code is reusable with centralized management, because the Shared VPC allows you to connect multiple service projects to a single host project that contains the network resources2. This way, you can use Terraform modules to create and manage the network resources in the host project, and then reference them in the service projects3.
Option A is incorrect because it does not create separate Google Cloud projects for each internal project, which makes it harder to delete the infrastructure and assign project owners. Option B is incorrect because it does not create separate Google Cloud projects for each internal project, and also because it attaches the service projects to a Shared VPC, which is not recommended for short-lived projects2. Option C is incorrect because it does not use a Shared VPC, which means that each internal project has to create and manage its own network resources, which increases complexity and reduces reusability.

質問 # 85
Question:
You are troubleshooting connectivity issues between Google Cloud and a public SaaS provider. Connectivity between the two environments is through the public internet. Your users are reporting intermittent connection errors when using TCP to connect; however, ICMP tests show no failures. According to users, errors occur around the same time every day. You want to troubleshoot and gather information by using Google Cloud tools that are most likely to provide insights into what is occurring within Google Cloud. What should you do?

A. Enable and review Cloud Logging on your Cloud NAT gateway. Look for logs with errors matching the destination IP address of the public SaaS provider.
B. Enable and review Cloud Logging for Cloud Armor. Look for logs with errors matching the destination IP address of the public SaaS provider.
C. Enable the Firewall insights API. Set the deny rule insights observation period to one day. Review the insights to assure there are no firewall rules denying traffic.
D. Create a Connectivity Test by using TCP, the source IP address of your test VM, and the destination IP address of the public SaaS provider. Review the live data plane analysis and take the next steps based on the test results.

正解：D

解説：
When troubleshooting connectivity issues, especially over public internet connections with intermittent errors, Connectivity Tests in Network Intelligence Center are crucial. This tool allows you to simulate the connectivity and understand the data plane status of Google Cloud resources. Since ICMP tests pass but TCP tests fail intermittently, using Connectivity Tests with TCP parameters will provide detailed insight into possible network issues like route misconfigurations, peering issues, or other transient problems affecting only specific protocols.
