Which of the following descriptions of lossless network prioritization design for multivariate computing is wrong?
The correct answer is D. In a VXLAN lossless network, switching devices can directly schedule traffic based on the priority. Resolution: A or B are two priority identities that can be trusted and queued for either of them. Option C is a best practice and is designed non-destructively for RoCE traffic alone. Priority scheduling is based on the outer priority identifier of the tunnel protocol. The…

Which of the following descriptions of lossless network prioritization design for multivariate computing is wrong?
Options
- AHuawei data center switches support the 8021p priority-based PFC function
- BHuawei data center switches support the PFC function based on DSCP priority
- CYou need to plan a separate priority queue for RoCE traffic and enable the PFC feature
- DIn a VXLAN lossless network, switching devices can directly schedule traffic based on the priority

Explanation
Resolution: A or B are two priority identities that can be trusted and queued for either of them. Option C is a best practice and is designed non-destructively for RoCE traffic alone. Priority scheduling is based on the outer priority identifier of the tunnel protocol. The vxlan protocol is no exception, so D is incorrect.
