   A security auditor is reviewing a virtualized environment and requires that a compromised VM cannot access the hypervisor or other VMs. The environment uses a Type 1 hypervisor. Which control is most important to implement?

   • AUse the same VLAN for all VMs to simplify management
   • BKeep the hypervisor patched and disable unnecessary services
   • CDisable the hypervisor's memory protection features
   • DEnable VM-to-VM traffic on the virtual switch

   A security administrator is concerned about a VM being compromised and then used to attack other VMs on the same host. The VMs are connected to the same virtual switch. Which control is most effective at limiting lateral movement between VMs?

   • APlace VMs in separate VLANs and restrict traffic with firewall rules
   • BDisable the virtual switch's promiscuous mode
   • CUse MAC address filtering on the virtual switch
   • DEnable hypervisor-level intrusion detection

   How does clustering support high availability in a virtualized environment?

   • ABy disabling automatic restarts
   • BBy grouping hosts so that VMs can be restarted on another host if one fails
   • CBy storing all VMs on a single server
   • DBy providing a single point of failure

   Why is isolation important in a virtualized environment?

   • AIt eliminates the need for network security
   • BIt ensures all VMs run the same operating system
   • CIt allows VMs to share memory directly for performance
   • DIt prevents a compromised VM from affecting other VMs on the same host
