Which AWS provider version constraint is specified by the example configuration?

• A. Requires any version of the AWS provider > 3.0
• B. Requires any version of the AWS provider >= 3.0
• C. Requires any version of the AWS provider >= 3.0 and < 4.0
• D. Requires any version of the AWS provider after the 3.0 major release, like 4.1

Answer: (C)

Version constraints define which provider versions Terraform is allowed to use. They use expressions like lower and upper bounds separated by a comma, where the comma acts as a logical AND: both conditions must be satisfied for a version to be eligible. In the example, the constraint is set to a lower bound of 3.0 and an upper bound less than 4.0. This means any 3.x version is acceptable (3.0, 3.1, 3.2, etc.), but versions in the 4.x series are not allowed. The reason this is the best choice is that it keeps you within the stable 3.x line, taking advantage of bug fixes and features without risking breaking changes that often come with a new major release (4.x and beyond). Why the other options don’t fit: requiring any version greater than 3.0 excludes 3.0 itself. Requiring versions greater or equal to 3.0 would allow 4.x versions, which is not desired here. And specifying versions only after the 3.0 major release would point to 4.x and later, which again contradicts targeting the 3.x line.
