Final Chamber • Performance-Based Question
A security architect needs a datacenter with a 99.999% SLA. Place the correct firewall deployment in each slot. (Full simulation has five rows covering routers, load balancers, and power systems; this teaser only shows the firewall rows.)
Datacenter Row 2 (ingress firewall pair)
Datacenter Row 3 Left (east-west firewall pair)
Correct answer: Active-active firewalls in both slots. With a 99.999% SLA there is no budget for the failover delay of an active-passive pair. Active-active shares traffic in real time, so a single node failure does not drop the session. Layer 4 is a filtering mode, not a deployment style.
Preview only • The full simulation has 25 slots to place, including routers, load balancers, power supplies, UPS systems, and upstream circuits.
