Exam AWS Certified Solutions Architect - Professional topic 1 question 812 discussion

A and D have no sense. C is wrong because it's very difficult to configure CUR on hundreds of accounts. B looks good.

B is the only valid option to conclude all bills from all OUs. D - is not possible how can you visualize CUR with OpsCenter? A - RAM cant create CUR C - Not efficient and not possible with organization since it creates one CUR for all accounts

First of all, I understood that one account can see the reports for all others accounts in the same OU only, so we need to create one report for each OU. It looks to me that there is no reasonable option for this question, if there was an option to create CUR using AWS system Manager and view the report using Amazon QuickSight that would be my response. IMO, it can't be letter B because there is a limit of 10 CUR per account (https://docs.aws.amazon.com/cur/latest/userguide/billing-cur-limits.html), then the management account will not be allowed to create all the reports, one by OU. With AWS System Manager you can automate a runbook and run it in multiple AWS accounts, configuring the S3 bucket and CUR. Guys, I would like to hear from you about my thoughts, Thanks in advance.

Condition: The organization has hundreds of AWS accounts. Use AWS Organizations management account to reduce administration overhead. "If you are **an administrator of an AWS Organizations management account and do not want any of the member accounts in your Organization to set-up a CUR** you can do one of the following:" Reference: https://docs.aws.amazon.com/cur/latest/userguide/what-is-cur.html

I wouldn't go with C but isn't B wrong since all teams will view all reports??
