Selected Answer: A
As it is the DB hostname and not sensitive credentials I think ssm dynamic is the correct answer. Option D - is for secure string whereas this parameter is currently stored in plain text. For option C, I opted against this because for an import value, I believe there needs to be an export value from another template. The question didn't state that anything else was created via CF template. Option B - I understand to be used to reference another resource block that is in the same YAML template.

Selected Answer: A
To reference a plaintext value stored in Parameter Store in your template, you use the ssm dynamic reference pattern. This pattern allows you to reference values from parameters of type String or StringList in Parameter Store.
