Avaya Aura Communication Applications Technical Associate Implement Free Sample Questions

Avaya best practices for multi-server Breeze clusters require that each Breeze server node has its own unique Entity Link configured in System Manager. Pointing a single Entity Link to a load balancer is not a supported configuration and leads to unpredictable routing behavior by Session Manager, causing service instability. Session Manager needs to be aware of each individual node to manage SIP sessions correctly.

When configuring a SIP Entity for Avaya Aura Messaging in System Manager, the correct selection for the 'Type' field is 'Other'. While options like 'Voicemail Server' or 'AAM' might seem more logical, they are incorrect. Selecting 'Other' allows for the specific FQDN and port configurations required by AAM to be entered manually, ensuring correct routing and feature integration with Session Manager.

PPM requires a secure connection to Session Manager. The standard and required configuration is for the Session Manager's SIP endpoint-facing Listen Port to be configured for the TLS protocol on port 5061. Using an unsecure protocol like TCP on 5060 will allow basic registration and calling but will cause the secure PPM download to fail.

The Default Domain in Session Manager's SIP Entity configuration is crucial for SIP endpoints, especially remote ones, to register and authenticate correctly. If this domain is missing or does not match the domain expected by the endpoints, the initial registration may succeed for basic calls, but advanced services like PPM will fail authentication and download.

TSAPI is the ideal choice for this scenario. It is a highly scalable, event-driven protocol designed specifically for third-party call control (3PCC) applications like CTI screen pops and agent state monitoring. It provides robust call control and event reporting without the overhead of media stream manipulation, which is a key feature of DMCC. JTAPI offers similar functionality but is Java-specific, whereas TSAPI is language-agnostic.

Avaya Aura Presence Services uses the Extensible Messaging and Presence Protocol (XMPP) for instant messaging and presence. By default, unencrypted XMPP traffic uses port 5222. For secure, encrypted communication, XMPP is tunneled over TLS (Transport Layer Security), which uses the dedicated port 5223. Therefore, configuring clients and firewalls for port 5223 enables XMPP over TLS.

The SBCE graphical user interface includes a powerful Packet Capture utility that allows an administrator to capture traffic on specific network interfaces with filters, and then download the capture file (in .pcap format) for analysis in a tool like Wireshark.

For administrators comfortable with the command line, accessing the SBCE via SSH and using the tcpdump command is a valid and powerful method to capture network traffic directly on the device. This provides real-time capture capabilities and advanced filtering options.

TCP Connection Multiplexing is a feature in Session Manager designed specifically to reduce the number of concurrent TCP connections. When enabled, Session Manager can use a single TCP connection to carry SIP traffic for multiple endpoints or entities, significantly reducing resource consumption and improving scalability in large deployments.

Role-Based Access Control (RBAC) is the specific feature within the AE Services Management Console designed to manage administrative permissions. It allows for the creation of different user roles (e.g., administrator, operator, viewer) with granular control over which management functions each role can access, perfectly suiting the scenario's requirements.

The correct navigation path in System Manager to manage and view the status of Avaya Breeze clusters and their deployed snap-ins is under the 'Elements' section. From there, selecting 'Avaya Breeze' and then 'Cluster Administration' for the specific cluster will display detailed information, including the status of all associated snap-ins (e.g., Active, Inactive, Error).

This scenario requires two different types of flows. A SIP Server Flow is used to define the routing and adaptation logic for connections to other SIP servers, such as a service provider's SBC. A SIP Subscriber Flow is used to define the origination and termination policies for individual SIP subscribers (endpoints) as they register and place calls. Using both flow types is the correct way to handle these distinct use cases.
