A user has configured an SSL(secure TCP) listener at a Classic Load Balancer for 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.

Answer – D
Option A is invalid because if the front-end connection uses TCP or SSL, your back-end connections can use either TCP or SSL. If the front-end connection uses HTTP or HTTPS, then your back-end connections can use either HTTP or HTTPS.
Option B is invalid because when you use TCP/SSL for both front-end and back-end connections, your load balancer forwards the request to the back-end instances without modifying the headers.
Option C is invalid because with this configuration you do not receive cookies for session stickiness. But, when you use HTTP/HTTPS, you can enable sticky sessions on your load balancer.
Option D is CORRECT because with SSL configuration the load balancer will forward the request to the back-end instances without modifying the headers.
