reuse! not duplicated! so it is A.

Yes i have reused same LogicalID for link with other resource

B: the logical name not ID

You may reuse the same logical ID multiple times, keyword being reuse. The logical ID is still unique, and it is, so the answer is A

B. False, a logical ID must be unique within the template.

B. It should be unique. Why people here are confused?

Again the wording "reuse" can you reuse it? No, can you reference it to add a resource to it i.e an EBS store yes. Does it have to be unique within a template yes. So if I am understanding the wording here...Can you "reference" a logical id more than once? Yes i.e adding 2 EBS volumes to it...You would use the logical ID to add each volume. Can you "reuse" that ID for a different resource? No...So what am I missing here? Seems like A to me.

A. Logical ID "The logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. Use the logical name to reference the resource in other parts of the template. For example, if you want to map an Amazon Elastic Block Store volume to an Amazon EC2 instance, you reference the logical IDs to associate the block stores with the instance." From http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/concept-resources.html

Shouldn't this be A, according to it's own supporting information: In AWS CloudFormation, the logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. You use the logical name to reference the resource in other parts of the template. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/concept-resources.html
