How are policies applied within an ACI fabric?

Show Suggested Answer Hide Answer
Suggested Answer: A

Understand ACI Fabric: ACI fabric policies are applied to manage and control the network traffic within the fabric1.

Identify Policy Application: Policies in ACI are applied between Endpoint Groups (EPGs), which are collections of network endpoints with common policy requirements1.

Recognize Policy Direction: These policies can be applied in a unidirectional or bidirectional manner, providing flexibility in controlling the flow of traffic between EPGs1.

Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco's guidelines on ACI fabric policies, which state that policies can be applied between two or more EPGs and can be either unidirectional or bidirectional1.

C is too narrow. We need more options for EPGs. A covers it well.

B seems too restrictive. Policies should not be limited to bidirectional.

D is too restrictive, I don't think unidirectional policies are the only option here.

C looks good, but I'm not sure if limiting to only two EPGs is the right approach.

I'm leaning towards B, as bidirectionality is a key requirement for policies in an ACI fabric.

I vaguely recall that policies can be unidirectional, but I can't remember if that means they can also be applied between more than two EPGs.

I’m a bit confused about whether policies can only apply to two EPGs or more. I feel like I need to double-check that part.

I remember practicing a question similar to this, and I think it was about how EPGs interact. I feel like option A might be correct.

I think policies can be applied between multiple EPGs, but I'm not sure if they have to be bidirectional or if unidirectional is also allowed.

I've got this one. Policies are applied between two EPGs, and the EPGs can be either unidirectional or bidirectional. The key is that they don't all have to be the same. I'll go with option A.

Wait, I'm a bit confused. I thought the EPGs had to be bidirectional, not unidirectional. Let me re-read the question and options.
