An administrator needs to create an IP allocation policy for a multi-tiered application running in a vApp. The IP addresses should be allocated automatically by vCenter Server, but should not be relea

Static - Manual requires the administrator to individually assign each IP address rather than having vCenter automatically allocate one from a pool.

Transient - IP Pool does allocate IPs automatically from a pool, but it releases the address back to the pool as soon as the VM is powered off, which violates the requirement for persistent allocation.

DHCP delegates IP assignment to an external DHCP server rather than to vCenter Server itself, and provides no guarantee that a VM will receive the same address after a power cycle.

Static - IP Pool directs vCenter Server to automatically select and assign an IP address from a pre-configured IP pool, removing the need for manual administrator assignment. Unlike the Transient model, the assigned address is retained by the VM even when it is powered off or suspended, satisfying the requirement for persistent addressing in a multi-tiered application. The IP is only released back to the pool when the VM is deleted from the vApp entirely.
