Implementing Cisco ACI Advanced (DCACIA) — Question 86

An engineer must implement an L3Out within a tenant to allow the reachability to services outside of the Cisco ACI fabric. The requirement is to allow communication from the EPGs in the same VRF to the external services and save TCAM resource utilization. Which contract insertion method must be used to meet these requirements?

Answer options

• A. Provider: each service EPGs - Consumer: vzAny inside the VRF
• B. Provider: each service EPGs - Consumer: L3Out external EPGs
• C. Provider: L3Out external EPGs - Consumer: each service EPGs
• D. Provider: L3Out external EPGs - Consumer: vzAny inside VRF

Correct answer: B

Explanation

The correct answer is B because it allows each service EPG to communicate with the L3Out external EPGs, which is necessary for reachability to external services. Options A and D incorrectly use vzAny, which does not meet the specific requirement to save TCAM resources. Option C reverses the provider and consumer roles, which does not align with the requirement for communication from EPGs to external services.
