You are asked to set up an IP fabric that supports Al or ML workloads. You have chosen to use lossless Ethernet in this scenario, which statement is correct about congestion management?

A.
The switch experiencing the congestion notifies the source device.
Answers
A.
The switch experiencing the congestion notifies the source device.
B.
Only the source and destination devices need ECN enabled.
Answers
B.
Only the source and destination devices need ECN enabled.
C.
ECN marks packets based on WRED settings.
Answers
C.
ECN marks packets based on WRED settings.
D.
ECN is negotiated only among the switches that make up the IP fabric for each queue.
Answers
D.
ECN is negotiated only among the switches that make up the IP fabric for each queue.
Suggested answer: A

Explanation:

Understanding Lossless Ethernet and Congestion Management:

Lossless Ethernet is crucial for AI and ML workloads, where packet loss can significantly degrade performance. To implement lossless Ethernet, congestion management protocols like ECN (Explicit Congestion Notification) are used.

Role of ECN in Congestion Management:

Option A: In an IP fabric that supports lossless Ethernet, when a switch experiences congestion, it can mark packets using ECN. This marking notifies the source device of the congestion, allowing the source to reduce its transmission rate, thereby preventing packet loss.

Conclusion:

Option A: Correct---The switch experiencing congestion notifies the source device via ECN marking.
