Google Professional Cloud Network Engineer Practice Test - Questions Answers, Page 21

Your organization wants to deploy HA VPN over Cloud Interconnect to ensure encryption-in-transit over the Cloud Interconnect connections. You have created a Cloud Router and two encrypted VLAN attachments that have a 5 Gbps capacity and a BGP configuration. The BGP sessions are operational. You need to complete the deployment of the HA VPN over Cloud Interconnect. What should you do?

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?

You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?

You have recently taken over responsibility for your organization's Google Cloud network security configurations. You want to review your Cloud Next Generation Firewall (Cloud NGFW) configurations to ensure that there are no rules allowing ingress traffic to your VMs and services from the internet. You want to avoid manual work. What should you do?

You are deploying an HA VPN within Google Cloud. You need to exchange routes dynamically between your on-premises gateway and Google Cloud. You have already created an HA VPN gateway and a peer VPN gateway resource. What should you do?

Your organization is developing a landing zone architecture with the following requirements:

There should be no communication between production and non-production environments.

Communication between applications within an environment may be necessary.

Network administrators should centrally manage all network resources, including subnets, routes, and firewall rules.

Each application should be billed separately.

Developers of an application within a project should have the autonomy to create their compute resources.

Up to 1000 applications are expected per environment.

You need to create a design that accommodates these requirements. What should you do?

Your organization wants to set up hybrid connectivity with VLAN attachments that terminate in a single Cloud Router with 99.9% uptime. You need to create a network design for your on-premises router that meets those requirements and has an active/passive configuration that uses only one VLAN attachment at a time. What should you do?

You recently deployed Cloud VPN to connect your on-premises data center to Google Cloud. You need to monitor the usage of this VPN and set up alerts in case traffic exceeds the maximum allowed. You need to be able to quickly decide whether to add extra links or move to a Dedicated Interconnect. What should you do?

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?
