Which statement describes the external database requirement for the Cisco IM and Presence permanent group chat feature?
A. All nodes in a Cisco IM and Presence cluster can share a physical external database.
B. All nodes in a Cisco IM and Presence cluster can share a logical external database.
C. Each node in a Cisco IM and Presence cluster must have its own physical external database.
D. Each node in a Cisco IM and Presence cluster must have its own logical external database.
E. An external database is not mandatory.
Answer: Option D.
Explanation:
When you configure an external database entry on IM and Presence, you assign the external database to a node, or nodes, in your cluster as follows:
. For the Compliance feature, you require at least one external database per cluster. Depending on your deployment requirements, you can also configure a separate external database per node.
. For the Permanent Group Chat feature, you require a unique external database per node. Configure and assign a unique external database for each node in your cluster.
. If you deploy both the Permanent Group Chat and Compliance features on an IM and Presence node, you can assign the same external database to both features.
