The primary log directory for Avaya IX Messaging application services is IX-Messaging Install drive:\UC\IX\Logs. When troubleshooting data synchronization issues between the Consolidated Server (CS) and Voice Server Nodes (VSNs), this is the correct folder to investigate. It contains specific log files, such as DataSync.log, which records the activities and potential errors of the Data Sync service responsible for replicating data across the messaging network. Analyzing these logs is a critical step in diagnosing and resolving synchronization failures.

B. IX-Messaging Install drive > UC > Logs: This is an incorrect and overly generic path. The specific logs for the IX Messaging application are located within the \IX sub-directory.

C. IX-Messaging Install drive > UC > DB > Logs: This path is incorrect. While database-related logs might exist, the application-level logs for data synchronization are not stored here.

D. IX-Messaging Install drive > UC > Logs > DB: This is not the standard directory structure for Avaya IX Messaging application logs.

1. Avaya Aura® Messaging Documentation Library, "Troubleshooting Avaya Aura® Messaging" (Release 10.8, NN42050-711, Issue 1.0, December 2020).

Page 111, Section: Log files: "The log files for Avaya Aura® Messaging are located in the Install\drive:\UC\IX\Logs folder." This section explicitly confirms the correct log file path. It also lists DataSync.log as one of the key logs within this directory for troubleshooting.

The correct installation sequence for an Avaya IX™ Messaging High Availability (HA) solution is critical for a successful deployment. The process begins with installing the WebLM server, which manages the necessary licenses for all other components. Next, the Primary Application Server is installed, establishing the initial configuration and database. Following this, the Consolidated Server, which provides centralized storage for the HA pair, is deployed. Finally, all Secondary Application Servers are installed. This order ensures that the primary system and its dedicated storage are operational before the redundant servers are added to the cluster.

A: The WebLM server is a prerequisite and must be installed first to provide licenses; it cannot be installed after the Primary Server.

B: According to the official Avaya deployment procedure, the Primary Application Server is installed before the Consolidated (storage) Server.

D: The Consolidated Server provides essential shared storage for the HA cluster and must be installed and configured before the Secondary servers.

1. Avaya Aura® Messaging Documentation Library, "Deploying Avaya Aura® Messaging", Release 10.1, February 2020.

Reference: Chapter 4: High Availability solution deployment, Section: "High Availability solution deployment workflow". This section explicitly outlines the installation order as: 1. Deploy WebLM server, 2. Deploy the first Application Server (Primary), 3. Deploy the Storage Server (Consolidated), 4. Deploy the second Application Server (Secondary). This directly supports option C.

2. Avaya Learning, "Avaya Aura® Messaging Implementation and Maintenance (71800X) Courseware".

Reference: Module on "High Availability Installation". The course materials detail the step-by-step process for deploying an HA environment, which specifies that the Primary Application server is installed after WebLM but before the Consolidated Storage server, which in turn must be installed before any Secondary servers.

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.

1. Avaya Aura® Messaging Documentation Library, "Implementing Avaya Messaging Release 11.0," Issue 3, December 2020.

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).

Avaya Messaging Release 11 server software is designed exclusively for installation on specific Microsoft Windows Server operating systems. According to the official installation and configuration documentation, the supported platforms are Windows Server 2019, Windows Server 2016, and Windows Server 2012 R2. Both Standard and Datacenter editions of these operating systems are supported. The installation requires a 64-bit architecture, and the server must be a dedicated machine for the Avaya Messaging application to ensure optimal performance and stability.

D. MAC operating systems: Avaya Messaging server components are not developed for or supported on any version of Apple's macOS.

E. 2008 Standard Edition: Windows Server 2008 is an older, unsupported operating system that does not meet the minimum system requirements for Avaya Messaging Release 11.

1. Avaya. (December 2019). Installing and Configuring Avaya Messaging Release 11.0 (Issue 3). Page 12, Chapter 2: System requirements, Section: "Server requirements", Subsection: "Operating system". The document explicitly lists "Microsoft Windows Server 2019 Standard or Datacenter", "Microsoft Windows Server 2016 Standard or Datacenter", and "Microsoft Windows Server 2012 R2 Standard or Datacenter" as the supported operating systems.

The DBWatchdog service is a critical component in Avaya Aura® System Manager responsible for ensuring the high availability of the database. Its primary function is to continuously monitor the state of the main SQL database service (e.g., PostgreSQL or SQL Anywhere). If the DBWatchdog service detects that the database service has stopped, regardless of whether it was stopped manually or due to an error, it will automatically initiate a restart of the database service to restore system functionality and minimize downtime.

A. DBWatcher: This is not the correct name for the Avaya service. While the name is descriptive, the official service is named DBWatchdog.

B. SQLANYsASADBJJC: This is the default service name for the SQL Anywhere database instance used by System Manager's JBoss application server, not the monitoring service that restarts it.

D. SALANYmConsolidated: This is an incorrect or misspelled service name and does not represent the monitoring process responsible for restarting the database.

Page 110, Table 16: Services: This table lists and describes the key services running on System Manager. It explicitly states the function of the DBWatchdog service as: "Monitors the database and restarts the database if the database is not running." It also identifies SQLANYsASADBJJC as "The System Manager database service." This directly confirms that DBWatchdog is the monitor and SQLANYsASADBJJC is the service being monitored.
