Google Cloud Certified Associate Cloud Engineer Practice

Pub/Sub is the recommended best practice for exporting your audit logs as it provides scalability and reliability. App Engine is not recommended because it has limitations on data retention and may not be suitable for long-term storage. Flushing your audit logs monthly is not recommended as it may lead to missed security events and is not a scalable solution. Cloud Storage can be used to store the exported audit logs, but it is not the recommended best practice as it does not provide real-time monitoring and alerting capabilities like Pub/Sub does.
