- A
Contracts can be reused across multiple EPGs.
A contract can be applied to many EPG pairs, allowing reuse and simplified policy management.
- B
Contracts are unidirectional from consumer to provider.
Why wrong: Contracts are directional, but they allow one-way traffic from provider to consumer (by default). Unidirectional from consumer to provider is incorrect.
- C
A contract can include multiple subjects.
A contract can contain multiple subjects, each with its own filters, to define different types of allowed traffic.
- D
Subjects within a contract specify only the destination ports.
Why wrong: Subjects define filters that can include source and destination ports, protocol, and other L4 parameters.
- E
Contracts are always bidirectional.
Why wrong: Contracts are unidirectional; to allow two-way traffic, two contracts or a single contract with filters covering both directions are needed.
Quick Answer
The answer is that a contract can include multiple subjects, and a contract is a reusable policy construct. This is correct because Cisco ACI contracts are designed to group one or more subjects—each defining a specific filter and action—into a single policy, allowing granular traffic control between EPGs. On the Cisco DCCOR / CCNP Data Center Core 350-601 exam, this concept tests your understanding of how contracts decouple policy from topology; a common trap is assuming each contract can only contain one subject or that contracts are tied to a single EPG. Remember that reusability is the core principle: you define a contract once, then apply it to many EPGs to enforce consistent rules without duplication. A helpful memory tip is to think of a contract as a folder containing multiple subject documents—each subject is a distinct rule set, but the folder itself is the portable policy you attach anywhere.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Contracts can be reused across multiple EPGs.
Option A is correct because Cisco ACI contracts are designed as reusable policy constructs. Once a contract is defined, it can be applied to multiple EPGs (Endpoint Groups) without redefining the rules, promoting consistency and reducing administrative overhead. This reusability is a core principle of ACI's policy-based networking model.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that contracts are strictly unidirectional from consumer to provider, when in fact they are bidirectional by default, with filters providing granular control over traffic direction.
Detailed technical explanation
How to think about this question
Under the hood, an ACI contract is a container for one or more subjects, each of which contains filters that define allowed traffic based on Layer 4 parameters (e.g., TCP/UDP ports) and optional Layer 3/4 attributes. The contract direction is enforced by the VRF (Virtual Routing and Forwarding) and the contract's scope (e.g., global, tenant, VRF), which determines how EPGs communicate. In a real-world scenario, a contract might allow HTTP traffic from a web EPG (consumer) to an app EPG (provider) while also permitting return traffic, but a filter could block specific ports or protocols in one direction.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

1 more ways this is tested on 350-601
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. In a Cisco ACI fabric, the administrator notices that traffic between two endpoints in different EPGs but on the same leaf switch is being dropped when a contract is applied. The endpoints are in the same VRF but different bridge domains. What is the likely cause?
hard- A.The VRF is not configured correctly.
- B.The bridge domains are not in the same network.
- C.The leaf switch is missing a route to the destination.
- ✓ D.The contract does not allow communication between those EPGs.
Why D: In Cisco ACI, inter-EPG communication is governed by contracts. Even when endpoints reside on the same leaf switch, same VRF, and different bridge domains, traffic is dropped unless a contract explicitly permits the communication between the source and destination EPGs. The contract defines the filter (e.g., IP protocol, ports) and the direction (provider/consumer) required for traffic to flow.
