Enable Packet Mirroring on your application and send test traffic.

Use Network Intelligence Center’s Network Topology visualizations.

Enable VPC Flow Logs and send test traffic.

Q93. You want to set up two Cloud Routers so that one has an active Border Gateway Protocol (BGP) session, and the other one acts as a standby.
Which BGP attribute should you use on your on-premises router?

AS-Path

Community

Local Preference

Multi-exit Discriminator

Q94. Your on-premises data center has 2 routers connected to your Google Cloud environment 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 a unique 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.
* BGP sessions are established between both on-premises routers and the Cloud Router.
* Only 1 of the on-premises router’s routes are being added to the routing table.
What is the most likely cause of this problem?

The on-premises routers are configured with the same routes.

A firewall is blocking the traffic across the second VPN connection.

You do not have a load balancer to load-balance the network traffic.

The ASNs being used on the on-premises routers are different.

Q95. You need to restrict access to your Google Cloud load-balanced application so that only specific IP addresses can connect.
