Case Study:
A remote worker reports that they can establish a call, but they experience 'one-way audio' (they can hear the other party, but the other party cannot hear them). The administrator captures a trace on the ASBCE and observes that the RTP packets from the remote worker are being blocked.
Upon reviewing the ASBCE configuration, the administrator notices that the 'Media Rule' is set correctly, but the firewall between the internet and the ASBCE might be misconfigured.
Which ASBCE feature helps resolve NAT traversal issues for remote workers by acting as a relay for media streams?
Show answer details
Correct answer: A
For remote workers behind residential NATs, ASBCE provides STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) services. If direct media fails (one-way audio), the endpoint should use TURN to relay media through the ASBCE's public interface.

You are configuring a 'Server Profile' in ASBCE for a new SIP Trunk. The Service Provider requires Mutual TLS (mTLS) authentication. Which two ASBCE components must be configured and associated with this Server Profile to meet this requirement? (Select TWO)
Show answer details
Correct answer: A, B
A TLS Client Profile is required so the ASBCE can present its own certificate to the Service Provider during the handshake (acting as the client).
A TLS Server Profile is required to define the CA certificate used to validate the Service Provider's certificate when they connect to the ASBCE.

When integrating Avaya Aura Presence Services with Communication Manager, what is the purpose of the 'Presence Services Connector' configured in System Manager?
Show answer details
Correct answer: A
The Presence Services Connector (often using AES) bridges the telephony world with the presence world. It monitors the user's phone status (On a Call, Idle) and updates the Presence Service so that IM clients show the correct 'On the Phone' status automatically.
- 4
The Avaya Aura Web Gateway (AAWG) provides a 'Unified Portal' for users. Which port is the standard HTTPS port used by end-users to access this portal from their browser?
Show answer details
Correct answer: A
The AAWG Unified Portal is a web-based interface designed to be accessed via standard HTTPS, which uses port 443 by default.
- 5
A customer is deploying Branch Survivability using Avaya Aura Branch Session Manager (BSM). In the event of a WAN failure where the branch loses connection to the Core, how does the BSM handle local station registrations?
Show answer details
Correct answer: A
When the WAN is down, the Branch Session Manager (BSM) takes over the role of the Core Session Manager for that branch. It accepts SIP registrations from local phones and routes traffic to the Local Survivable Processor (LSP) or local gateways to ensure PSTN connectivity.

A support engineer is troubleshooting a reported issue where users cannot see the presence status of external federated contacts, although internal presence is working correctly. The engineer verifies that the Avaya Breeze cluster is active and the Presence Services snap-in is running. Which specific log file location on the Avaya Breeze node should be analyzed to investigate XMPP federation errors?
Show answer details
Correct answer: A
The primary log file for the Presence Services snap-in on the Avaya Breeze platform is located at /var/log/Avaya/services/PresenceServices/PresenceServices.log. This log captures XMPP federation events, subscription requests, and internal processing errors specific to the Presence application.

During a maintenance window, an administrator needs to remove an Avaya Breeze node from the cluster for hardware replacement. The administrator puts the node into 'Deny New Service' state. What is the immediate impact of this action on the Presence Services running on that node?
Show answer details
Correct answer: A
Placing a Breeze node in 'Deny New Service' state allows the node to continue handling active sessions to ensure a graceful shutdown, but it will reject any new incoming requests (such as new presence subscriptions). This allows the load to naturally drain to other nodes in the cluster.

A technician is configuring the Avaya Session Border Controller for Enterprise (ASBCE) to support Remote Workers. While testing with a SIP endpoint outside the network, the registration succeeds, but the phone cannot download its configuration file (PPM). Which ASBCE component configuration is most likely missing or incorrect?
Show answer details
Correct answer: A
Remote workers download Personal Profile Manager (PPM) data via HTTP/HTTPS. The ASBCE must have a Reverse Proxy Rule configured to forward these HTTP requests from the external interface to the Session Manager's internal management address. If SIP works but PPM fails, the Reverse Proxy configuration is the primary suspect.
- 9
When troubleshooting a SIP Trunking issue on the ASBCE, a support engineer needs to capture a live trace of SIP messages to verify the headers being sent to the Service Provider. Which Command Line Interface (CLI) tool should be used to capture these messages in real-time with filtering capabilities?
Show answer details
Correct answer: A
traceSBC is the specific command-line tool on the Avaya SBCE used to capture and analyze SIP traffic in real-time. It allows for extensive filtering by IP address, call ID, or method, and displays the full SIP ladder diagram logic.

An organization is deploying Application Enablement Services (AES) to support a new recording solution. The recording application requires the ability to monitor and record calls using the Device Media Call Control (DMCC) protocol. Which two services must be enabled and configured on the AES to support this requirement? (Select TWO)
Show answer details
Correct answer: A, B
The DMCC Service must be enabled to allow the application to register virtual softphones and access media streams.
Most recording applications also require TSAPI to monitor call events (like delivered, established, cleared) to trigger the recording logic, even if the media is captured via DMCC.
