Question

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 to what is occurring within Google Cloud. What should you do?

Explanation

Google Cloud's Connectivity Tests tool provides detailed insights into network paths and issues between Google Cloud resources and external endpoints. By creating a TCP-based connectivity test to the destination IP address of the SaaS provider, the engineer can: - Analyze the full network path, including routing and firewall rules within Google Cloud. - Identify issues such as misconfigured routes, firewalls, or NAT gateways. - Gain insights into live traffic flows, which can help diagnose intermittent connectivity errors. Since ICMP is working, the issue may be protocol-specific (TCP). Connectivity Tests allow you to specifically test TCP connections and analyze the results, providing the most actionable insights for troubleshooting. This approach directly targets the problem and helps narrow down the root
