Which additional application must be deployed alongside AVP to allow network connectivity through its services port?

The correct answer is Utility Services (US). Utility Services is an essential component in the Avaya Aura architecture, serving as a mechanism for facilitating various operational capabilities, including network connectivity through services ports. When deployed alongside the Application Server (like AVP), Utility Services enables monitoring, auditing, and provides a centralized point for service management.

The role of Utility Services is critical because it aids in the management of shared resources and provides the necessary configurations that other applications, including AVP, rely on for proper functionality. This supports an integrated approach to handling services across the Avaya platform.

Other options, such as Secure Access Link (SAL) Gateway, Avaya Diagnostic Server (ADS), and Avaya Aura System Manager (SMGR), serve specific purposes within the Avaya ecosystem but do not directly fulfill the requirement for network connectivity via the services port in the same way that Utility Services does. SAL Gateway is primarily focused on secure communication, ADS is meant for diagnostics and troubleshooting, and SMGR is for management and configuration tasks. While each plays a vital role in the overall functionality of the Avaya system, Utility Services specifically addresses the need for connectivity in conjunction with AVP.
