Question 520
An enterprise architecture team faces this design requirement: A central networking account must share an existing Transit Gateway with application accounts without duplicating it. Which selection is defensible under the given constraints?
Explanation
Correct Answer
AWS RAM can share supported resources while ownership remains in a central account. The required architecture outcome is: A central networking account must share an existing Transit Gateway with application accounts without duplicating it.
