You need to test if your Compute Engine firewall rules are blocking traffic to a public-facing application. What is the correct troubleshooting step to take?
A
Enable Firewall Rules Logging on the latest rules that were changed. Use Logs Explorer to analyze whether the rules are working correctly.
B
Connect to a bastion host in your VPC. Use a network traffic analyzer to determine at which point your requests are being blocked.
C
In a pre-production environment, disable all firewall rules individually to determine which one is blocking user traffic.
D
Enable VPC Flow Logs in your VPC. Use Logs Explorer to analyze whether the rules are working correctly.
