A. B. C. D.Answer - A and B.
The AWS Documentation mentions the following.
CloudFront is designed to scale for viewers with different client IP addresses and different DNS resolvers across multiple geographic regions.
To perform load testing that accurately assesses CloudFront performance, we recommend that you do all of the following.
· Send client requests from multiple geographic regions.
· Configure your test so that each client makes an independent DNS request.
Each client will then receive a different set of IP addresses from DNS.
· For each client that is making requests, spread your client requests across the set of IP addresses that are returned by DNS, which ensures that the load is distributed across multiple servers in a CloudFront edge location.
Option C is incorrect since you need to initiate the request to the Cloudfront distribution.
Option D is incorrect since there is no mention of a secure request in the question.

https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/load-testing.htmlWhen performing a load test on a CloudFront distribution, it's essential to keep in mind the following factors:
A. Ensure to initiate client requests from multiple geographic regions: It's important to test the performance of the CloudFront distribution from different locations to make sure that the content is being delivered quickly and efficiently to all users, regardless of their geographic location. This will help to identify any latency issues, and also ensure that the distribution is optimized to serve content from edge locations that are closest to the end-user.
B. Configure your test so that each client makes an independent DNS request: When testing the performance of a CloudFront distribution, it's important to ensure that each client makes an independent DNS request. This will help to identify any DNS-related issues, such as slow DNS lookups, that could impact the performance of the distribution.
C. Ensure that client requests hit the origin server: During a load test, it's important to ensure that client requests hit the origin server. This will help to identify any bottlenecks or issues that could impact the performance of the distribution. It's also important to monitor the origin server's performance during the load test to ensure that it can handle the increased traffic.
D. Ensure that SSL is turned on for the distribution: SSL (Secure Sockets Layer) should be enabled on the CloudFront distribution to ensure that data transmitted between the end-user and the distribution is encrypted. This is important for protecting sensitive information, such as login credentials and payment information, from being intercepted by malicious third parties.
In summary, when performing a load test on a CloudFront distribution, it's important to initiate client requests from multiple geographic regions, configure the test so that each client makes an independent DNS request, ensure that client requests hit the origin server, and ensure that SSL is turned on for the distribution.
