Which of the following will allow for configuration of a round robin, load balanced environment?

A DMZ is a network security zone that isolates public-facing servers from internal infrastructure, not a mechanism for load balancing or traffic distribution.

FAT (File Allocation Table) is a legacy disk file system format used for data storage, and has no relationship to load balancing or network traffic management.

HTTPS load balancers operate at Layer 7 (application layer) and can be configured to distribute incoming client requests across multiple backend servers using a round-robin algorithm. This makes HTTPS the appropriate context for configuring a round-robin, load-balanced environment, as the other choices are file systems or network zones entirely unrelated to traffic distribution.

EXT refers to extended file system types used in Linux environments for disk storage, not a network or server configuration technology capable of load balancing.
