   A multinational corporation wants to conduct a penetration test on its cloud infrastructure, which spans multiple regions. The security team must ensure the test complies with data protection regulations in all regions. What is the most important step in planning the test?

   • ARun the test only in the region with the most stringent regulations to ensure compliance.
   • BConduct the test without informing local authorities, as penetration testing is generally allowed.
   • CUse a single penetration testing tool that works across all regions to simplify the test.
   • DReview the data protection regulations in each region to determine if any restrictions apply to penetration testing.

   A fintech startup wants to build a continuous reliability testing strategy. They have limited engineering resources and must balance testing with feature development. Which approach is most sustainable?

   • ARun all tests only when a major feature is released, to minimize the impact on development.
   • BAutomate load tests in the CI/CD pipeline, and schedule chaos and penetration tests to run automatically on a regular basis.
   • CFocus only on load testing, since it is the most important type of reliability testing.
   • DRun a comprehensive suite of chaos, penetration, and load tests manually once a quarter.
