ACI COOP Endpoint Type: Bounce Entry vs Remote
Short answer
D The endpoint type used when entries are pushed down from the COOP database is a bounce entry.
Question
Key Takeaways
The question tests the specific terminology used in Cisco ACI for endpoints learned through the Council of Oracle Protocol (COOP) rather than direct Layer 2/3 learning.
This page clarifies that when entries are pushed from the spine's COOP database to leaf switches, they are classified as bounce entries. It explains the distinction between these COOP-learned endpoints and standard remote endpoints learned via the data plane.
Common mistake: Most candidates incorrectly select 'remote' because the endpoint is indeed remote, but fail to recognize that the specific mechanism of COOP dissemination creates a 'bounce entry'.
Expert Analysis
Why the Answer Is Correct
In Cisco ACI, the Council of Oracle Protocol (COOP) is used by spine switches to distribute endpoint location information to leaf switches. When a leaf switch receives this information from the spine to locate an endpoint it did not learn directly, the resulting entry is specifically termed a "bounce entry". This distinguishes it from endpoints learned directly on the leaf's own interfaces.
Why the Other Options Are Wrong
While "remote" accurately describes the physical location of the endpoint, it is not the technical term for the entry type created by COOP distribution. The ACI fabric documentation explicitly categorizes COOP-learned entries as bounce entries to differentiate them from locally learned or directly connected endpoints. "On-peer" refers to endpoints on the same switch, and "local" refers to endpoints directly connected to the leaf.
Community Comment Notes
The community is divided, with many users voting for D based on the understanding that "A bounce entry is basically a remote endpoint created by COOP communication instead of data-plane learning." Others argue for A, stating that remote endpoints are those learned via the COOP database. However, the precise terminology defined by Cisco for this specific COOP-pushed entry is "bounce entry".
Exam Strategy
Focus on specific Cisco ACI terminology distinctions. Do not rely solely on logical descriptions like 'remote'; memorize the exact terms used in the architecture guides for COOP, EPGs, and endpoint learning.

prospio971 👍 1 Answered AIn Cisco ACI, remote endpoints are entries that are not directly connected to a local leaf switch but are learned via the COOP (Council of Oracle Protocol) database stored on the spine switches. When a leaf switch needs to forward traffic to an endpoint that is not locally connected, it queries the spine's COOP database to retrieve the necessary information about the remote endpoint.
