Exam 200-901 topic 1 question 29 discussion

D is correct. XML does not support arrays but JSON does.

D is correct because of keyword "natively"

B is not correct. "As a markup language, XML is more complex and requires a tag structure. In contrast, JSON is a data format that extends from JavaScript. It does not use tags, which makes it more compact and easier to read for humans." https://aws.amazon.com/compare/the-difference-between-json-xml/

Natively is the key

D seems to be correct, note that it says "natively"

I'm not sure about B since JSON is more readable than XML, well this is subjective if the person is used to XML

In XML, arrays can be represented using repeating elements with the same name

Option A is incorrect. Both XML and JSON support mapping data structures into host languages, although the specific mechanisms for doing so may differ. Option C is incorrect. Both XML and JSON support a variety of data types, including strings, numbers, and Booleans. Option D is incorrect. Both XML and JSON support arrays, although the syntax for representing arrays is different in the two formats. In XML, arrays can be represented using repeating elements with the same name, while in JSON, arrays are represented using square brackets.

D is correct.
