F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 11

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.
How should the LTM Specialist resolve this issue?

Answer options

• A. Add an HTTP profile to both virtual servers.
• B. Enable SNAT Automap on both virtual servers.
• C. Create a custom persistence profile and enable "Map Proxies."
• D. Create a custom persistence profile and enable "Match Across Services."

Correct answer: D

Explanation

The correct answer is D because enabling 'Match Across Services' allows the persistence profile to maintain the user's session across different virtual servers, which is necessary for keeping the shopping cart intact during the port change. The other options do not address the need for session persistence across the two different ports, which is why they would not resolve the issue.
