   A service provider is deploying VM-Series firewalls on a KVM-based host with 32 physical cores and 256 GB RAM. The firewall will inspect 10 Gbps of mixed traffic and must sustain peak throughput without packet drops. The administrator plans to allocate 8 vCPUs and 16 GB RAM. Which additional configuration is most important to ensure the VM-Series performs consistently under load?

   • APin the VM-Series vCPUs to dedicated physical cores and set a CPU reservation equal to the full vCPU allocation.
   • BEnable memory ballooning on the VM to allow the hypervisor to reclaim unused RAM dynamically.
   • CSet the VM-Series disk controller to virtio-scsi with write-back caching for the data plane.
   • DConfigure the VM-Series with 16 vCPUs to match the physical core count of the host.

   In capacity planning for VM-Series handling encrypted traffic, which factor is most important to consider when estimating the required number of instances?

   • AThe storage capacity of the hypervisor
   • BThe number of network interfaces per instance
   • CThe expected SSL/TLS throughput per instance
   • DThe management plane CPU usage

   What is the primary performance impact of enabling hyperthreading on a host running VM-Series?

   • AIt guarantees a linear increase in firewall throughput
   • BIt eliminates CPU contention between VMs
   • CIt can improve CPU utilization by allowing more threads to run concurrently
   • DIt reduces the need for vCPU allocation
