Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 333

An engineer implements an environment with multiple traffic types on a consolidated I/O link between Cisco Nexus 9000 Series Switch and MDS 9000 Series Switch. The configuration must meet these requirements:
• The unified I/O link must support LAN and SAN traffic.
• A single, multipurpose Ethernet transport must be used.
• The configuration must discard MAC addresses that are not part of the current fabric.
• The QoS markings must be preserved.

Which configuration set meets the requirements?

Answer options

• A. MDS-A(config)# interface fcip4 - MDS-A(config-if)# use-profile 8 - MDS-A(config-if)# peer-info ipaddr 200.200.100.7
• B. N9K-2(config)# interface Eth2 - N9K-2(config-if)# switchport mode trunk N9K-2(config-if)# auto qos trust dscp
• C. MDS-B(config)# interface fc3 - MDS-B(config-if)# switchport trunk mode on MDS-B(config-if)# switchport trunk allowed vsan 2-5
• D. N9K-1(config)# fcoe fcmap 0e.fc.1d N9K-1(config)# int vfc 1 - N9K-1(config-if)# bind interface e1/3

Correct answer: D

Explanation

Option D is correct as it binds the virtual Fibre Channel interface to the Ethernet interface, allowing for the unified I/O link that supports both LAN and SAN traffic while preserving QoS markings. Options A and C do not address the requirements related to the unified I/O link and the specific configuration needed for traffic types, while option B only configures Ethernet settings without fulfilling the broader requirements.
