FCoE achieves higher performance with the use of which of the following?

Data Center Bridging Exchange (DCBX) is a protocol that enables capabilities like Priority-based Flow Control (PFC) and Enhanced Transmission Selection (ETS) for lossless Ethernet, which is critical for FCoE but does not directly achieve higher performance through larger frame sizes.

Priority tagging (802.1p) provides Quality of Service (QoS) by marking traffic for prioritized handling, which helps ensure FCoE traffic gets preference, but it does not directly increase data transfer performance by modifying frame size.

VLAN tagging (802.1Q) segments network traffic into separate broadcast domains, which is used to logically separate FCoE traffic but does not inherently provide higher performance for the data transfer itself.

FCoE leverages Baby-jumbo frames, which are Ethernet frames larger than the standard 1500-byte MTU but smaller than full jumbo frames (e.g., 9000 bytes), typically around 2180 bytes. This increased frame size reduces the overhead of processing multiple smaller frames, thereby improving the overall throughput and performance of Fibre Channel traffic encapsulated within Ethernet.
