Designing Cisco Data Center Infrastructure (DCID) — Question 200

An ACI deployment must:
• Only use a proxy for border leaf switches.
• Classify incoming traffic on L3OUT.
• Immediately update the endpoint database when the endpoint moves between leaf switches.

Which VRF configuration must be used?

Answer options

• A. Ingress Policy Control enforcement Egress Policy Control enforcement IP Dataplane Learning enabled
• B. Enforce Subnet Check disabled - IP Dataplane Learning disabled - Ingress Policy Control enforcement
• C. Enforce Subnet Check enabled - IP Dataplane Learning enabled - Egress Policy Control enforcement
• D. Ingress Policy Control enforcement Enforce Subnet Check enabled - IP Dataplane Learning disabled

Correct answer: C

Explanation

The correct answer is C because it enables both Enforce Subnet Check and IP Dataplane Learning, which are necessary for efficient endpoint tracking and ensuring proper traffic management in an ACI environment. Options A and D either do not enable IP Dataplane Learning or have incorrect configurations, while option B disables critical features, failing to meet the requirements.
