What is one disadvantage of using dynamic blocks in Terraform?

The correct answer is A. They cannot be used to loop through a list of values. The recognized disadvantage of dynamic blocks is that they make configuration harder to read and understand (option C) - complex or deeply nested dynamic blocks obscure intent compared to explicit static blocks, which is why HashiCorp recommends using them sparingly. Option A…

Explanation

The recognized disadvantage of dynamic blocks is that they make configuration harder to read and understand (option C) - complex or deeply nested dynamic blocks obscure intent compared to explicit static blocks, which is why HashiCorp recommends using them sparingly. Option A is factually false: dynamic blocks are specifically designed to iterate over lists or maps using 'for_each', so the claim that they cannot loop through lists is wrong. Option B describes an advantage. Option D is not a documented concern. The provided answer key lists A, but A is an incorrect statement about dynamic blocks. The correct answer is C.
