CCDE Practical Exam — Question 24

An organization deploys active-active data centers and active-standby firewalls in each data center. Which action should be taken in a Cisco ACI Multi-Pod to maintain traffic symmetry through the firewalls?

Answer options

• A. Enable Endpoint Dataplane Learning
• B. Disable service node Health Tracking
• C. Enable Pod ID Aware Redirection
• D. Disable Resilient Hashing

Correct answer: B

Explanation

Disabling service node Health Tracking is essential in this scenario to avoid disruptions in traffic symmetry through the firewalls, which can occur if health checks interfere with traffic routing. The other options, such as enabling Endpoint Dataplane Learning or Pod ID Aware Redirection, do not address the specific issue of maintaining symmetry, while disabling Resilient Hashing may not be necessary and could lead to uneven traffic distribution.
