301b Exam Question 30
-- Exhibit-


-- Exhibit -
Refer to the exhibits.
After upgrading LTM from v10 to v11, users are unable to connect to an application. The virtual server is using a client SSL profile for re-terminating SSL for payload inspection, but a server SSL profile is being used to re-encrypt the request.
A client side ssldump did NOT show any differences between the traffic going directly to the server and the traffic being processed by the LTM device. However, packet capture was done on the server, and differences were noted.
Which modification will allow the LTM device to process the traffic correctly?
