Implementing Cisco Application Centric Infrastructure (DCACI) — Question 103

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

Correct answer: C

Explanation

The correct answer is C because aligning the ACI QoS levels with IPN QoS policies ensures that the required DSCP values are properly prioritized, preventing delays or drops. Options A and B do not address the necessary configurations for QoS alignment, while option D focuses on a specific tenant policy rather than the overarching QoS alignment needed across pods.
