To answer this question, you need to understand how attributes of SMS (System Managed Storage) datasets can be copied from one dataset to another.
Option A) Using DD like parameter - This option is correct because the DD LIKE parameter can be used to copy the attributes of one SMS dataset to another. When specifying DD LIKE=dataset-name, the attributes of the dataset named "dataset-name" are copied to the new dataset.
Option B) Using DD Copy parameter - This option is incorrect because there is no DD COPY parameter available for copying attributes of SMS datasets.
Option C) Using DD Refer parameter - This option is incorrect because there is no DD REFER parameter available for copying attributes of SMS datasets.
Option D) Attributes cannot be copied within SMS datasets - This option is incorrect because attributes of SMS datasets can indeed be copied using the DD LIKE parameter.
Therefore, the correct answer is A) Using DD like parameter. This option is correct because it allows for the attributes of one SMS dataset to be copied to another dataset.
