When using Cisco Unified Communications Manager IM and Presence Service in a federated network configuration, which statement about Message Archiver is true?

Sending the message to the remote cluster before archiving creates a gap where the message could be lost before the archive entry is written, which violates the intent of archiving.

Message Archiver is fully supported in federated network configurations; it is not limited to non-federated deployments.

The sender cluster is the authoritative point for archiving because it originates the message. By archiving before transmission, the local cluster guarantees a complete record regardless of whether the remote cluster successfully receives or processes the message. This design ensures the archive is tied to the message source, not the destination.

Archiving only on the remote cluster would mean the sender has no local record, and the remote cluster may not be under the same administrative control or compliance policy.
