Implementing Cisco ACI Advanced (DCACIA) — Question 9

A customer is deploying a new application across two ACI pods that is sensitive to latency and jitter. The application sets the DSCP values of packets to AF31 and
CS6, respectively. Which configuration changes must be made on the APIC to support the new application and prevent packets from being delayed or dropped between pods?

Answer options

• A. disable DSCP translation policy
• B. align the ACI QoS levels and IPN QoS policies
• C. disable DSCP mapping on the IPN devices
• D. align the custom QoS policy on the EPG site in the customer tenant

Correct answer: B

Explanation

The correct answer is B because aligning the ACI QoS levels with the IPN QoS policies ensures that the DSCP values set by the application are treated consistently across the network. Options A and C would potentially hinder the QoS handling of the packets, while option D does not address the need for alignment between ACI and IPN QoS settings.
