Designing Cisco Data Center Infrastructure (DCID) — Question 199
A network engineer designs a virtual network in a Cisco UCS Manager. The traffic must be explicitly forwarded from the vNIC on the server to a specific uplink Ethernet port on the Cisco fabric interconnect. Also, the server vNIC must use the same uplink Ethernet port after reboot. Finally, the design requires a QoS policy for remote direct memory access over converged Ethernet (RoCE v2). Which set of design features meets these requirements?
Answer options
- A. vNIC pool and Silver priority
- B. vNIC template and Gold priority
- C. server VLAN pool and Gold priority
- D. LAN pin group and Platinum priority
Correct answer: D
Explanation
The correct answer is D because a LAN pin group allows the vNIC to be pinned to a specific uplink port, ensuring consistent traffic flow even after a reboot. Additionally, Platinum priority provides the necessary QoS for RoCE v2. The other options do not provide the same level of control over uplink assignment or QoS requirements.
