ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

Your e-commerce platform runs two application servers in an active-passive cluster behind a health-checking load balancer. During a resilience test you hard-stop the active node; traffic is quickly redirected but customers are forced to log in again and open carts are lost. Which change would most effectively increase service availability during such failovers?

  • Enable stateful session replication (or a shared session store) so both nodes maintain identical user sessions in real time.

  • Move the passive node to a different network segment to add geographic diversity.

  • Replace the load balancer with round-robin DNS to distribute connections across both servers.

  • Increase the load balancer's health-check interval to reduce the likelihood of unnecessary failovers.
