Exam AWS Certified Database - Specialty topic 1 question 82 discussion

I will say 'B' too . the key for me to decide is the word 'number' since he wcu and rcu are numeric values.Not sure if my interpretation is correct ,but , will go with B

A and D are out, parameters are useful when you know the value for me mapping are like constant in any program language we can use them for Region, Accounts, AZ, etc and the question says "...allocate independently variable read and write capacity..." the word variable is key for me here. C- is out Output is for importing values into other stack. B is correct Use the optional Parameters section to customize your templates. Parameters enable you to input custom values to your template each time you create or update a stack. from https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html D -

"The organization want to modify the template in order to allocate independently variable read and write capacity units to future tables." this is the vital sentence in the question. Only Option is Parameter. Option B

Add values for two Number parameters, rcuCount and wcuCount, to the template. Replace the hard-coded values with calls to the Ref intrinsic function, referencing the new parameters.

Option B

I got this Question in exam.

definetly A

probably B

Why not A? It is obvious that there are multiple tables and rcu and wcu should be defined for each of them. I think mapping is a must here.

yes B for dynamic and not pre-determined values

GOing with B https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html

B is correct
