Google Cloud Professional Cloud Security Engineer Practice Exam

To troubleshoot firewall rule issues suspected of causing application outages, what action should be taken?

1. Delete the latest firewall rule

2. Enable Firewall Rules Logging and analyze logarithms

3. Revert to the previous set of firewall rules

4. Contact Google Cloud Support for incident assistance

The correct answer is: Enable Firewall Rules Logging and analyze logarithms

Enabling Firewall Rules Logging and analyzing the logs is a proactive and effective approach to troubleshooting firewall rule issues. This method allows the engineer to gather detailed information regarding the traffic that is being allowed or denied by the firewall rules. By examining these logs, patterns and anomalies can be identified, which can give insights into whether particular rules are blocking legitimate traffic that an application requires, or whether there are any configuration mistakes. Analyzing the logs also allows for a deeper understanding of which specific rules are causing issues. This data-driven approach facilitates informed decisions on modifying current rules or creating new ones based on observed network behavior and application needs. Overall, this is a systematic way to diagnose issues rather than making reactive changes that may lead to further complications.
