F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 109

An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart.
The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.
What is the issue?

Answer options

• A. The port 80 pool member is deleting the user's session cookie.
• B. The port 443 pool member is deleting the user's session cookie.
• C. The port 80 and port 443 connections are balanced to the same node.
• D. The port 80 and port 443 connections are balanced to different nodes.

Correct answer: D

Explanation

The issue arises because the shopping cart data is stored in memory, and the connections on ports 80 and 443 are directed to different nodes, preventing the session persistence required to maintain the cart's state. Options A and B incorrectly attribute the problem to session cookies being deleted, while option C suggests the connections are going to the same node, which would not lead to the cart being empty.
