What will AWS do in this case?

An organization is using cost allocation tags to find the cost distribution of different departments
and projects. One of the instances has two separate tags with the key/ value as
“InstanceName/HR”, “CostCenter/HR”. What will AWS do in this case?

A.
InstanceName is a reserved tag for AWS. Thus, AWS will not allow this tag

B.
AWS will not allow the tags as the value is the same for different keys

C.
AWS will allow tags but will not show correctly in the cost allocation report due to the same
value of
the two separate keys

D.
AWS will allow both the tags and show properly in the cost distribution report

Explanation:
AWS provides cost allocation tags to categorize and track the AWS costs. When the user applies
tags to his AWS resources, AWS generates a cost allocation report as a comma-separated value
(CSV file. with the usage and costs aggregated by those tags. Each tag will have a key-value and
can be applied to services, such as EC2, S3, RDS, EMR, etc. It is required that the key should be
different for each tag. The value can be the same for different keys. In this case since the value is
different, AWS will properly show the distribution report with the correct values.
