Google Cloud Certified - Professional Cloud Network Engineer 認定 Professional-Cloud-Network-Engineer 試験問題 (Q36-Q41):

質問 # 36
You manage two VPCs: VPC1 and VPC2, each with resources spread across two regions. You connected the VPCs with HA VPN in both regions to ensure redundancy. You've observed that when one VPN gateway fails, workloads that are located within the same region but different VPCs lose communication with each other. After further debugging, you notice that VMs in VPC2 receive traffic but their replies never get to the VMs in VPC1. You need to quickly fix the issue. What should you do?

正解：D

解説：
The problem description indicates that VMs in VPC2 receive traffic but their replies don't reach VPC1, especially when a VPN gateway fails. This strongly suggests an asymmetric routing issue, where VPC2's routing table might not be aware of all necessary routes to send return traffic to VPC1, particularly in a multi- region setup with failover. By default, VPC networks are in regional dynamic routing mode, meaning they only learn routes from Cloud Routers in the same region. To ensure that routes learned from one region (where the active VPN tunnel might be) are available globally across the VPC, you need to enable global dynamic routing mode in the VPC that is experiencing the return traffic issue (VPC2 in this case). This allows VPC2 to learn and apply routes from Cloud Routers in all regions, ensuring that even if a VPN tunnel fails in one region, the routes learned from the active tunnel in another region are still available for return traffic.
Exact Extract:
"A VPC network's dynamic routing mode controls whether routes learned by Cloud Routers in one region are available to VMs in other regions. By default, VPC networks are in regional dynamic routing mode, which means Cloud Routers in a region only advertise routes to and learn routes from other Cloud Routers in the same region. This can lead to asymmetric routing issues in multi-region deployments."
"To ensure that routes learned from Cloud Routers are propagated to all regions within a VPC network, you must set the dynamic routing mode to global."Reference: Google Cloud VPC Documentation - Dynamic routing mode


質問 # 37
The applications in your Google Cloud environment and your AWS cloud environment frequently exchange large volumes of data, and the existing Cloud VPN connections are not meeting the required throughput and reliability. You need to establish high-performance, low-latency, highly available connectivity between your Google Cloud environment and your AWS cloud environment. You also need to create a dedicated, private connection between your Google Cloud VPC and your AWS VPC. What should you do?

正解：D

解説：
Cross-Cloud Interconnect is designed for private, dedicated connectivity between Google Cloud and another cloud provider such as AWS. It provides high-bandwidth, low-latency connectivity and supports BGP peering over the dedicated connection between your Google Cloud VPC and AWS environment. This fits the requirement for a dedicated, private, highly available connection better than Cloud VPN, while avoiding the extra complexity of assembling separate interconnect products through a colocation design yourself Reference:

質問 # 38
You need to configure a static route to an on-premises resource behind a Cloud VPN gateway that is configured for policy-based routing using the gcloud command.
Which next hop should you choose?

正解：B

解説：
When you create a route based tunnel using the Cloud Console, Classic VPN performs both of the following tasks:
Sets the tunnel's local and remote traffic selectors to any IP address (0.0.0.0/0) For each range in Remote network IP ranges, Google Cloud creates a custom static route whose destination (prefix) is the range's CIDR, and whose next hop is the tunnel.

質問 # 39
You have applications running in the us-west1 and us-east1 regions. You want to build a highly available VPN that provides 99.99% availability to connect your applications from your project to the cloud services provided by your partner's project while minimizing the amount of infrastructure required. Your partner's services are also in the us-west1 and us-east1 regions. You want to implement the simplest solution. What should you do?

正解：A

質問 # 40
You want to deploy a VPN Gateway to connect your on-premises network to GCP. You are using a non BGP-capable on-premises VPN device. You want to minimize downtime and operational overhead when your network grows. The device supports only IKEv2, and you want to follow Google-recommended practices.
What should you do?

正解：B

解説：
When you create a route based tunnel using the Cloud Console, Classic VPN performs both of the following tasks:
Sets the tunnel's local and remote traffic selectors to any IP address (0.0.0.0/0) For each range in Remote network IP ranges, Google Cloud creates a custom static route whose destination (prefix) is the range's CIDR, and whose next hop is the tunnel.
