Accepted Answer

SIP signaling and RTP media streams between the PBX and the messaging server.

Accepted Answer

SNMP trap messages from the messaging server to the network management station.

Answer

RDP access from administrator workstations to the messaging server.

Answer

ICMP traffic for ping tests between all network devices.

Question 2

A multinational corporation is planning a deployment of Avaya IX Messaging to support a user base of 75,000 employees across three global regions. The requirement is to maintain a single system image while ensuring High Availability (HA) and local survivability. Based on the system architecture limits, which deployment strategy adheres to the valid scalability constraints for a distributed Voice Server Node (VSN) configuration?

Accepted Answer

Implement a distributed VSN architecture where the total user count does not exceed 80,000 users, utilizing multiple VSNs managed by a primary server.

Answer

Deploy a single Consolidated Server at the headquarters and use remote gateways for the regional sites.

Answer

Deploy two independent High Availability pairs, each supporting 37,500 users, without linking them as a single system.

Answer

Use a single VSN with vertical scaling to support all 75,000 users on one physical server instance.

Question 3

When configuring High Availability (HA) for Avaya IX Messaging, specific roles must be assigned to the servers to ensure proper data replication and failover. In a standard HA pair configuration, which statement correctly describes the relationship and configuration requirements between the Primary and Secondary servers?

Accepted Answer

The Primary server manages the configuration database, and the Secondary server maintains a synchronized copy via real-time replication, ready to take over services if the Primary fails.

Answer

The Secondary server must be installed with a read-only database schema that is promoted to read-write only during failover.

Answer

Both servers operate in an active-active load balancing mode for all database transactions by default.

Answer

The Secondary server handles all voice traffic while the Primary server is dedicated solely to database management.

Question 4

An architect is designing a messaging solution that requires secure communication between the Voice Server Node and the PBX. Which protocol and configuration setting must be enabled on the Voice Server Node to encrypt the signaling traffic?

Accepted Answer

TLS with a valid certificate and port 5061

Answer

UDP with port 5060

Answer

TCP with port 5060

Answer

IPsec tunneling on port 1720

Question 5

Which component in the Avaya IX Messaging architecture is primarily responsible for converting email text into spoken audio for retrieval via the Telephone User Interface (TUI)?

Accepted Answer

Text-to-Speech (TTS) Engine

Answer

Automatic Speech Recognition (ASR) Engine

Answer

Content Sync Engine (CSE)

Answer

Message Networking Server

Question 6

True or False: A single Avaya IX Messaging system can support a maximum of 120,000 users in a High Availability configuration.

Accepted Answer

False

Answer

True

Question 7

A technical consultant is designing the storage subsystem for a new Avaya IX Messaging server that will host over 400 Unified Messaging users. To ensure optimal performance and redundancy, which RAID configuration is the recommended best practice for this scenario?

Accepted Answer

RAID 10

Answer

RAID 0

Answer

RAID 1

Answer

RAID 5

Question 8

When integrating Avaya IX Messaging with a PBX using SIP, which of the following diagrams best represents the correct flow of a call being diverted to voicemail?

Accepted Answer

Caller -> PBX -> (SIP INVITE) -> Messaging Server -> (200 OK) -> PBX -> (RTP) -> Messaging Server

Answer

Caller -> Messaging Server -> (SIP REFER) -> PBX -> (RTP) -> Messaging Server

Answer

Caller -> PBX -> (HTTP POST) -> Messaging Server -> (200 OK) -> PBX

Answer

Caller -> PBX -> (SMTP) -> Messaging Server -> (ACK) -> Caller

Question 9

A deployment involves 12,000 Advanced Users who require synchronization with Office 365. Based on the scaling guidelines for the Content Sync Engine (CSE), what is the minimum number of CSE servers required to support this workload?

Accepted Answer

3 Servers

Answer

1 Server

Answer

2 Servers

Answer

4 Servers

Question 10

A customer requests to implement a fax solution using SR140 software on a single Avaya IX Messaging Voice Server Node. They require support for 40 simultaneous fax channels. What is the correct response regarding the licensing capacity for this request?

Accepted Answer

The request cannot be fulfilled on a single server because the maximum supported SR140 fax ports per Voice Server Node is 24. A second Voice Server Node is required.

Answer

The request can be fulfilled as the SR140 software supports up to 60 ports per server.

Answer

The request can be fulfilled, but it requires a specialized hardware fax board instead of SR140 software.

Answer

The request cannot be fulfilled because the system-wide limit for fax ports is 30.
