Which of the following BEST describes a server where several physical server chassis are housed within an enclosure to share some redundant resources?

A tower server is a standalone server housed in an upright chassis, typically with its own dedicated power and cooling, not designed to share resources within an enclosure.

A rack mount server is designed to fit into a standard server rack but is generally a self-contained unit with its own power and cooling, not sharing redundant resources in the same manner as a blade chassis.

Blade servers are a high-density server form factor where several physical server 'blades' are installed into a shared chassis. This chassis provides consolidated and often redundant resources such as power supplies, cooling, and network switches, enabling efficient resource utilization and management.

A bare metal server refers to a physical server dedicated to a single tenant without virtualization, describing its usage rather than its physical form factor or resource-sharing architecture.
