350-601 Network Practice Question
In an ACI fabric, an EPG is configured with a contract that provides a service to another EPG. The contract has a filter for TCP port 80. Which component defines the directionality of the communication between the provider and consumer EPG?
⚠ Common exam trap
Cisco often tests the misconception that the filter direction (e.g., 'both' or 'uni') controls which EPG initiates traffic, when in fact it is the provider and consumer labels that define the directionality of the communication.

Correct answer & explanation
✓
The provider and consumer labels in the contract
In Cisco ACI, the provider and consumer labels in the contract define the directionality of communication. The provider EPG offers a service, and the consumer EPG initiates the request; the contract's provider/consumer relationship determines which EPG can start the conversation and in which direction the filter (e.g., TCP port 80) applies. This is fundamental to ACI's policy model, where the contract is unidirectional from consumer to provider by default.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The filter direction specified in the contract
Why it's wrong here
Filter direction is not used; contract direction is provider/consumer.
- ✗
The BD subnets
Why it's wrong here
BD defines Layer 2 boundary, not contract direction.
- ✓
The provider and consumer labels in the contract
Why this is correct
Correct: provider/consumer relationship defines direction.
- ✗
The subject of the contract
Why it's wrong here
Subject contains filters and actions, not directionality.
