Question 1
Q1A financial services company is experiencing intermittent connectivity drops for high-volume trading applications passing through their R81.20 ClusterXL Active-Active cluster. A preliminary analysis with fw ctl pstat shows a large number of non-sticky connections. The network administrator suspects that the default load-sharing mechanism is not correctly distributing TCP connections that lack a PUSH flag in the SYN packet. Which command should be executed on the cluster members to ensure these connections are handled by the same member and become sticky?
Show answer & explanation
Correct answer: C
The fwha_ls_syn_based_stickiness kernel parameter forces the cluster to make a stickiness decision based on the SYN packet alone, regardless of whether it contains a PUSH flag. This is the correct solution for ensuring TCP connections, especially from non-standard applications, are sticky and handled by a single member in an Active-Active Load Sharing cluster, preventing the described connectivity drops. The other options address different, unrelated stickiness behaviors.
