A developer needs to create a multi-tier development stack for a home lab. Which vSphere product will support the architecture required for the least software cost?

vSphere Hypervisor is VMware's free standalone ESXi edition that supports multiple concurrent VMs with advanced virtual networking features including VLANs and virtual switches, making it fully capable of hosting multi-tier development stacks with no licensing cost for the hypervisor software itself.

vSphere Essentials is a paid SMB licensing kit and therefore does not satisfy the least-cost requirement.

VMware Player is free but is designed for running single VMs with minimal networking flexibility, making it unsuitable for complex multi-tier stack architectures.

VMware Workstation supports multi-VM networking and tiered stacks but requires a paid license, so it does not meet the least-software-cost constraint.
