AWS WAF is configured for an Application Load Balancer. Sysops Team has enabled sampling requests for this Application Load Balancer. The Operations team is looking for ways to check the sample request and the time it will be stored.
Which is the correct statement for the sampled request?

Answer options:

A.Sampled Web Requests are stored for up to 3 hours and are available in the AWS WAF management console.
B.Sampled Web Requests are stored for up to 6 hours and are available in the Amazon CloudWatch console.
C.Sampled Web Requests are stored for up to 3 hours and are available in the Amazon CloudWatch console.
D.Sampled Web Requests are stored for up to 6 hours and are available in the AWS WAF management console.

Correct Answer: A
AWS WAF has two different ways to check how WAF ACL rules protect a resource. One-minute metrics can be used which are available in Amazon CloudWatch and are stored as per the time period configured with Amazon CloudWatch. Another way is to use Sampling requests which can be viewed from the AWS WAF console and are stored for up to 3 hours.
Option B is incorrect as Sampled Web requests are available in the AWS WAF console and not in Amazon CloudWatch.
Option C is incorrect as Sampled Web requests are available in the AWS WAF console and not in Amazon CloudWatch. These requests are stored for up to 3 hours and not 6 hours.
Option D is incorrect as Sampled Web requests are stored up to 3 hours and not 6 hours.
