CCIE Data Center (legacy) — Question 82

Which three statements are considered best practice when directly connecting converged network adapters to the fabric? (Choose three.)

Answer options

• A. Cisco Unified Fabric links must be configured as access ports and FCoE VLAN must not be configured as a native VLAN.
• B. Separate FCoE VLANs must be used for FCoE in SAN-A and SAN-B.
• C. If MSTP is enabled, a separate MST instance must be used for FCoE VlANs.
• D. If the converged access switches (in the same San fabric or in the other) must be connected to each over Ethernet links for the purposes of LAN alternate pathing, then sucj links must explicitly be configured to include all FCoE VLANs. This configuration ensures to extend the scope of the Spanning TreeProtocol for FCoE VLANs to Cisco Unified Fabric and non Cisco Unified Fabric links.
• E. Cisco UF links must be configured as spanning-tree edge ports.
• F. A shared VLAN can be used to carry traffic for each virtual fabric in the SAN (for example, VSAN 1, VSAN 2, and so on). BCE

Correct answer:

Explanation

The correct answers are A, B, and D, as they outline the necessary configurations for ensuring optimal connectivity and performance for FCoE traffic. Option C is incorrect because MSTP does not require a separate instance specifically for FCoE VLANs, while option E is not relevant to the direct connection best practices. Option F is also not appropriate as it suggests a shared VLAN, which can lead to potential conflicts in traffic management.
