A retail customer with a FortiADC HA cluster load balancing five webservers in L7 Full NAT mode is receiving reports of users not able to access their website during a sale event. But for clients that were able to connect, the website works fine.

CPU usage on the FortiADC and the web servers is low, application and database servers are still able to handle more traffic, and the bandwidth utilization is under 30%.

Which two options can resolve this situation? (Choose two.)

Answers
D.
Add a connection-pool to the FortiADC virtual server
Suggested answer: A, D

Explanation:

The FortiADC HA cluster is a load balancing solution that distributes traffic among multiple web servers in L7 Full NAT mode. L7 Full NAT mode means that FortiADC terminates both client and server SSL connections and performs full NAT for both source and destination IP addresses and ports.

One possible reason for users not being able to access the website during a sale event is that the persistence rule is not configured properly. Persistence rule is a feature that ensures that subsequent requests from the same client are sent to the same web server, which is important for maintaining session continuity and avoiding errors or data loss. The default persistence rule for L7 Full NAT mode is LB_PERSIS_SRC_IP, which uses the source IP address of the client as the persistence key. However, this rule may not work well if there are many clients behind a proxy or NAT device that share the same source IP address, or if there are clients that change their source IP address frequently due to roaming or switching networks. Therefore, to resolve this situation, one option is to change the persistence rule to LB_PERSIS_SSL_SESSJD, which uses the SSL session ID of the client as the persistence key. This rule can provide more accurate and reliable persistence for SSL connections than LB_PERSIS_SRC_IP. Another possible reason for users not being able to access the website during a sale event is that there are too many TCP connections being established and terminated between FortiADC and the web servers, which consumes CPU resources and causes performance degradation. Therefore, to resolve this situation, another option is to add a connection-pool to the FortiADC virtual server. Connection-pool is a feature that allows FortiADC to reuse existing TCP connections between FortiADC and the web servers, instead of creating new ones for each request.

This can reduce CPU overhead, improve response time, and increase throughput. Reference:
