Which two options are benefits of deploying FCoE beyond the access layer?
The correct answer is A. higher throughput compared to native Fibre Channel switches. C. reduction in equipment requirements. Deploying FCoE beyond the access layer consolidates SAN and LAN traffic over shared high-speed Ethernet, reducing equipment requirements and enabling throughput that can exceed older native FC speeds.

Why each option
Deploying FCoE beyond the access layer consolidates SAN and LAN traffic over shared high-speed Ethernet, reducing equipment requirements and enabling throughput that can exceed older native FC speeds.
FCoE over 10GbE, 25GbE, 40GbE, or 100GbE Ethernet links can deliver throughput that exceeds older 4 Gb or 8 Gb native Fibre Channel switch speeds, making higher throughput a valid and measurable benefit.
FCoE is explicitly designed to be extended beyond the access layer using FCoE Forwarder (FCF) capable aggregation and core switches.
Extending FCoE beyond the access layer allows aggregation and core switches to carry both storage and IP traffic simultaneously, eliminating the need for separate dedicated FC switching equipment and reducing overall infrastructure footprint.
FCoE does not inherently improve security over traditional Fibre Channel; both rely on zoning and similar fabric security mechanisms for isolation.
Increased application support is not a recognized technical benefit specific to deploying FCoE beyond the access layer.
