A fibre channel fabric needs to be portioned into smaller subsets to restrict actual communication throughout a fabric and must work on fibre channel level 2. Which of the following implementations mu

Hard zoning enforces communication restrictions based on physical Fibre Channel switch ports, preventing unauthorized devices from even seeing each other's frames, and operates at Fibre Channel Layer 2 for strong, port-based isolation.

Soft zoning restricts communication based on World Wide Names (WWN) but is less secure as devices can still see frames but are configured to ignore them, operating at a logical level rather than strict physical Layer 2.

E-port replication is not a zoning method; E-ports are used to connect Fibre Channel switches to expand the fabric, and replication refers to data copying, not fabric partitioning.

LUN masking is a storage array-level security feature that restricts host access to specific LUNs (Logical Unit Numbers) after a connection is established, operating at a higher layer than Fibre Channel fabric segmentation.
