AWS Certified SysOps Administrator – Associate (legacy) — Question 159

A user has configured an SSL listener at ELB as well as on the back-end instances. Which of the below mentioned statements helps the user understand ELB traffic handling with respect to the SSL listener?

Answer options

• A. It is not possible to have the SSL listener both at ELB and back-end instances
• B. ELB will modify headers to add requestor details
• C. ELB will intercept the request to add the cookie details if sticky session is enabled
• D. ELB will not modify the headers

Correct answer: D

Explanation

The correct answer is D because the ELB does not modify the headers when handling traffic with SSL listeners, preserving the original headers from the client. Options A, B, and C are incorrect because having SSL listeners at both the ELB and backend instances is allowed, the ELB does not add requestor details to the headers, and it does not intercept requests to add cookie information unless configured otherwise.
