Starting with Avaya Messaging Release 11.0, the system introduced a native, built-in replication mechanism to provide resilience between a primary and a secondary Consolidated Server. This change eliminated the dependency on third-party software, specifically Carbonite Availability (formerly Double-Take), which was required in previous releases. This native solution simplifies the deployment and management of a high-availability messaging environment by integrating the replication process directly into the Avaya Messaging application.

B. This is incorrect. Avaya Messaging Release 11 explicitly replaced the requirement for Carbonite software with its own integrated replication solution for resilience.

C. This is incorrect. The secondary/backup Consolidated Server is a core component of the Avaya Messaging resilience feature, which is fully supported in Release 11.

D. This is incorrect. The primary and secondary servers can be deployed in different geographical locations to provide disaster recovery, not just on the same LAN.

Page 110, Chapter 6: Resilience, Section: Resilience overview: "Avaya Messaging provides a resilience feature that uses a primary server and a secondary server. The system uses its own replication mechanism to keep the secondary server synchronized with the primary server. In previous releases, Avaya Messaging used Carbonite Availability for replication." This statement directly confirms that Carbonite is no longer required (Answer A) and that a secondary server is supported (refuting C).

Page 111, Chapter 6: Resilience, Section: Network requirements for resilience: "The primary and secondary servers can be in the same location or in different geographical locations." This statement directly refutes the claim that servers must be on the same LAN (Answer D).
