   A company has a VPC with multiple subnets and a complex set of firewall rules. They want to proactively identify any network configuration issues, such as suboptimal routing or potential connectivity problems, before they impact users. Which Network Intelligence Center feature should they use for this proactive health check?

   • AFirewall Insights to review firewall rule usage.
   • BNetwork Analyzer to review findings and warnings about the network.
   • CConnectivity Tests to check all possible paths between subnets.
   • DNetwork Topology to visually inspect the network.

   Users in a European office report that a web application hosted in a Google Cloud VPC in us-central1 is slow to respond. The application's backend VMs are in the same region. You suspect the issue is related to the internet path between the office and Google's network. Which tool should you use to investigate this specific concern?

   • AFlow Analyzer to examine the traffic from the office's public IP.
   • BConnectivity Test from the office's public IP to the backend VM.
   • CPerformance Dashboard to view latency and packet loss on the Google Cloud network path from Europe to us-central1.
   • DNetwork Topology to check the path from the office to the VPC.

   A network administrator wants to get a high-level view of the traffic flowing between two subnets in the same VPC to identify if a newly deployed application is generating an unexpected amount of traffic. They need to see the throughput between the subnets. Which Network Intelligence Center feature should they use?

   • ANetwork Topology to visualize the traffic flow and throughput between the subnets.
   • BPerformance Dashboard to check latency between the subnets.
   • CFlow Analyzer to query flow logs for traffic between the subnets.
   • DConnectivity Test from a VM in one subnet to a VM in the other.

   A network engineer is troubleshooting a VPC where some VMs cannot reach the internet. Network Topology shows the VMs are connected to a subnet with a route to the default internet gateway. The engineer suspects a firewall rule is blocking egress. Which Network Intelligence Center tool would provide the most direct confirmation of this specific issue?

   • AUse Network Analyzer to see if there are any warnings about the default route.
   • BRun a Connectivity Test from the affected VM to the public IP 8.8.8.8.
   • CReview Firewall Insights for any rules that are blocking egress traffic.
   • DCheck the Performance Dashboard for packet loss on the default route.
