Designing Cisco Network Service Architectures (ARCH, legacy) — Question 67

An engineer has been requested to utilize a method in an ACI network that will ensure only permitted communications are transmitted between each End Point
Group tier in a three tier application. Which element would be utilized to accomplish this within the fabric?

Answer options

• A. Filter
• B. Contract
• C. Label
• D. Subject

Correct answer: A

Explanation

The correct answer is A, Filter, which is specifically designed to control and permit communication between different End Point Groups in ACI. Options B, Contract, and C, Label, serve different roles in ACI, such as defining rules for communication and categorizing endpoints, but do not directly enforce the communication permissions in the same way as Filters do.
