4. D. Use Google Cloud's Web App and API Protection (WAAP).
5. E. Bots are creating accounts and then using the
6. F. Use Identity-Aware Proxy to re-strict the users to known users.
7. G. Automated testing tools might still be running and creating account
8. H. Use Identity-Aware Proxy to restrict the users to known users.

Correct Answer: B
Bots attacking the application is the most likely scenario in this case. Using WAAP is the right protection plan: Anti-DDoS, anti-bot, WAF, and API protection help you protect against new and existing threats while helping you keep your apps and APIs compliant and continuously available.
