最新的Google Cloud Certified - Professional Cloud Network Engineer - Professional-Cloud-Network-Engineer免費考試真題
Your company has just launched a new critical revenue-generating web application. You deployed the application for scalability using managed instance groups, autoscaling, and a network load balancer as frontend. One day, you notice severe bursty traffic that the caused autoscaling to reach the maximum number of instances, and users of your application cannot complete transactions. After an investigation, you think it as a DDOS attack. You want to quickly restore user access to your application and allow successful transactions while minimizing cost.

You successfully provisioned a single Dedicated Interconnect. The physical connection is at a colocation facility closest to us-west2. Seventy-five percent of your workloads are in us-east4, and the remaining twenty- five percent of your workloads are in us-central1. All workloads have the same network traffic profile. You need to minimize data transfer costs when deploying VLAN attachments. What should you do?
正確答案: B
You have enabled HTTP(S) load balancing for your application, and your application developers have reported that HTTP(S) requests are not being distributed correctly to your Compute Engine Virtual Machine instances. You want to find data about how the request are being distributed.

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.

Your organization has Compute Engine instances in us-east1, us-west2, and us-central1. Your organization also has an existing Cloud Interconnect physical connection in the East Coast of the United States with a single VLAN attachment and Cloud Router in us-east1. You need to provide a design with high availability and ensure that if a region goes down, you still have access to all your other Virtual Private Cloud (VPC) subnets. You need to accomplish this in the most cost-effective manner possible. What should you do?
正確答案: A
You have several VMs across multiple VPCs in your cloud environment that require access to internet endpoints. These VMs cannot have public IP addresses due to security policies, so you plan to use Cloud NAT to provide outbound internet access. Within your VPCs, you have several subnets in each region. You want to ensure that only specific subnets have access to the internet through Cloud NAT. You want to avoid any unintentional configuration issues caused by other administrators and align to Google-recommended practices. What should you do?
正確答案: B

Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-and-shift, and all requests to the servers will be served by a single network load balancer frontend.
