Question 1 of 30

A network operations center team is investigating intermittent performance issues affecting several critical client applications hosted within a Cisco ACI fabric. Analysis of traffic patterns and switch telemetry indicates that transactional data flows are experiencing increased latency and occasional packet loss, particularly during peak operational hours. The suspected root cause points to an inefficient allocation of egress bandwidth on a specific leaf switch serving these clients. Which of the following strategic adjustments to the QoS policy on the affected leaf switch would most effectively mitigate this issue by ensuring preferential treatment for high-priority transactional traffic?

Reconfigure the egress interface to utilize a strict priority queuing mechanism for all traffic classes, ensuring no bandwidth is guaranteed to lower-priority traffic.
Implement a weighted fair queuing (WFQ) approach across all traffic classes, distributing bandwidth proportionally based on configured weights, without explicit priority assignment.
Adjust the Quality of Service (QoS) policy to classify transactional traffic into a high-priority queue with a guaranteed minimum bandwidth allocation, while setting lower bandwidth limits for best-effort traffic.
Remove all QoS policies from the affected leaf switch to allow for unhindered packet flow, assuming the underlying network infrastructure can inherently manage traffic prioritization.
