Answer options:

D

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.
