You are working as a solution architect for a media firm. Your technical manager asks you to evaluate the cost of implementing AWS Config. Which of the following are components of AWS Config pricing? (Select TWO)

Answer options:

A.AWS Config is free; you are charged only for data recorded in the S3 bucket.
B.The number of AWS Config rules evaluations.
C.The total number of Config rules.
D.The number of Conformance pack evaluations.

Correct Answes: B and D
With AWS Config, you are charged based on the number of configuration items recorded, the number of active AWS Config rule evaluations and the number of conformance pack evaluations in your account. An AWS Config rule evaluation is a compliance state evaluation of a resource by an AWS Config rule in your AWS account, and a conformance pack evaluation is the evaluation of a resource by an AWS Config rule within the conformance pack.
Option A is incorrect – AWS config is not free, there is a charge based upon configuration item & number of active config rules. For Data recorded in the S3 bucket, there would be additional charges based upon standard rates in a region.
Option C is incorrect - AWS Config charges are only based upon Active rules, not a total number of rules.
