To answer this question, we need to understand what the NOERASE option does in relation to a data set.
The NOERASE option is used when defining a data set to prevent data from being overwritten or erased when new data is written to the data set. It is commonly used for sensitive data that should not be modified or deleted.
Let's go through each option to understand why it is correct or incorrect:
Option A) Desirable for sensitive data - This option is incorrect because the NOERASE option is indeed desirable for sensitive data. It ensures that the data remains intact and is not accidentally erased or modified.
Option B) Removes catalog entries - This option is incorrect because the NOERASE option does not remove catalog entries. It only prevents data from being overwritten or erased.
Option C) All the above - This option is incorrect because both Option A and Option B are true. Therefore, this statement is also true.
Option D) None - This option is correct because the statement "None" implies that all of the options are true, which is not the case. Option A is not true because the NOERASE option is desirable for sensitive data.
The correct answer is A) Desirable for sensitive data.
