   Which benefit does the Hyperscale Security Fabric (HSF) provide for private cloud resilience?

   • AIt allows firewall capacity to scale out by adding more VM-Series instances to the cluster.
   • BIt provides a single point of failure for easier troubleshooting.
   • CIt requires all firewalls to be in the same physical location.
   • DIt eliminates the need for load balancers in the data center.

   Which HA mode is most appropriate for a private cloud deployment where both firewalls must actively process traffic to maximize throughput, and session ownership is distributed between the two devices?

   • APassive/active with load balancing
   • BActive/active with asymmetric routing
   • CActive/passive with preemption enabled
   • DActive/active with symmetric return enabled

   A large enterprise runs a pair of PA-5250 firewalls in active/passive HA. The network carries a mission-critical TCP application and a UDP-based monitoring system. The architect needs to ensure that a failover does not interrupt the TCP application. The current failover takes 8 seconds, which is too long. The architect has already enabled session setup and state synchronization. What is the most effective additional configuration to reduce failover time for the TCP application?

   • ADisable state synchronization for TCP to reduce overhead.
   • BPre-allocate session resources on the passive firewall to avoid the delay of memory allocation during failover.
   • CIncrease the HA failover timer to give the passive firewall more time to process sessions.
   • DUse active/active HA mode to distribute TCP traffic.

   A large cloud provider is designing a private cloud with HSF. The provider must support a tenant that requires a dedicated firewall for compliance reasons. The tenant's traffic is a mix of TCP and UDP. The architect needs to ensure that the tenant's traffic is isolated and that a failure of one HSF node does not affect the tenant. What is the most important architectural consideration?

   • AHSF requires a dedicated management plane for each tenant.
   • BHSF requires a dedicated set of nodes for each tenant to ensure isolation.
   • CHSF provides a single logical firewall, but tenant isolation must be ensured through separate security zones and policies.
   • DHSF does not support tenant isolation, so the provider must use separate firewalls for each tenant.
