In DCBX feature negotiation, the switch and CNA exchange capability information and configuration values.
Which three capabilities are supported in Cisco Nexus 5000 Series Switches? (Choose three.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
In Data Center Bridging Capability Exchange (DCBX) negotiation, switches and Converged Network Adapters (CNAs) exchange capability information and configuration values to enable the converged network to operate properly.
The Cisco Nexus 5000 Series Switches support the following three capabilities in DCBX feature negotiation:
A. Priority Flow Control (PFC): PFC is a feature that enables lossless Ethernet by dedicating a portion of the bandwidth to high-priority traffic, preventing congestion in the network. PFC is essential in converged networks to ensure that storage and networking traffic can coexist without interference. The Cisco Nexus 5000 Series Switches support PFC through the DCBX feature negotiation process.
C. Fibre Channel over Ethernet (FCoE): FCoE is a technology that enables Fibre Channel traffic to run over Ethernet networks, allowing for consolidation of storage and networking traffic. The Cisco Nexus 5000 Series Switches support FCoE through the DCBX feature negotiation process.
E. Speed: DCBX enables the switch and CNA to negotiate the speed of the link between them. The Cisco Nexus 5000 Series Switches support speed negotiation through DCBX.
Therefore, the correct answers are A, C, and E.
Note that logical link up or down, multicast, and duplex are not capabilities supported in DCBX feature negotiation. Logical link up or down is a feature of Link Layer Discovery Protocol (LLDP), not DCBX. Multicast and duplex are not negotiable features in DCBX.
