Your customers have been reporting slow response times when accessing your web application.

Same Region Deployment:

Deploying FortiWeb Cloud in the same AWS region as your web application minimizes latency and ensures faster response times by reducing the distance data needs to travel (Option A).

Content Delivery Network (CDN):

Enabling a CDN can significantly improve response times by caching content closer to the end-users, reducing the load on the origin server, and speeding up content delivery (Option B).

Other Options Analysis:

Option C is incorrect because modifying DNS entries to directly point to your web server bypasses the WAF protection, which is not advisable for security reasons.

Option D is incorrect because disabling WAF functionality would expose your web application to vulnerabilities and threats, compromising security.
