Correct Answer: B

Avaya Aura Presence Services does not require a separate license file or an instance license. User licenses are an entitlement as part of the Avaya Aura suite licensing, such as Foundation, Mobility, Team Engagement, or Customer Engagement. The user licenses are consumed based on the number of users who are provisioned for Presence Services in System Manager

Correct Answer: C

When setting up the Avaya Session Border Controller for Enterprise (ASBCE) SIP Trunking, you need one Subscriber Flow and one Server Flow. A Subscriber Flow is a configuration object that defines how the ASBCE handles SIP requests and responses from or to an endpoint, such as an IP phone or a softphone. A Server Flow is a configuration object that defines how the ASBCE handles SIP requests and responses from or to a server, such as a Communication Manager or a Session Manager. For SIP Trunking, you need one Subscriber Flow that connects the ASBCE to the internal SIP server, and one Server Flow that connects the ASBCE to the external SIP service provider. These flows specify parameters such as source and destination IP addresses, ports, protocols, codecs, encryption, authentication, and routing rules3

Correct Answer: A

When deploying the Avaya Aura Presence Services on Avaya Breeze? you can check the status of the Presence Services snap-in in System Manager, under Elements > Avaya Breeze> Service Management > Services. The status indicates the state of the snap-in on the Avaya Breeze?cluster. The status Active means that the snap-in is running and ready to support Presence and IM. The other statuses are either intermediate or error states that indicate that the snap-in is not fully functional or operational.

Correct Answer: C

An H.248 signaling link connects the Internet Friendly (Edge) Gateway to Avaya Communication Manager (CM) by tunneling H.248 messages using TCP port 2944 and securing them using TLS. H.248 is a protocol that defines how media

gateway controllers control media gateways for supporting multimedia streams across different networks, such as IP networks and PSTN networks. An H.248 signaling link is a logical connection between an H.248 controller and an H.248

gateway that allows exchanging H.248 messages for controlling media streams. In an Internet Friendly (Edge) Gateway scenario, CM acts as an H.248 controller and ASBCE DBE acts as an H.248 gateway. To connect an H.248 signaling

link between CM and ASBCE DBE, these steps are performed:

CM initiates a TCP connection to ASBCE DBE using port 2944, which is reserved for H.248 over TLS.

CM and ASBCE DBE negotiate TLS parameters and exchange certificates for mutual authentication and encryption.

CM and ASBCE DBE establish a secure TLS session over TCP port 2944. CM and ASBCE DBE exchange H.248 messages over TLS session for controlling media streams.

Correct Answer: A

After running the Install wizard on the Avaya Session Border Controller for Enterprise (ASBCE), you add a Public (External) IP address to the Bl interface. The Bl interface is a logical interface that represents the external network port on the ASBCE server. The Bl interface is used to communicate with external entities, such as SIP service providers or remote workers. If you try to ping the Bl interface IP address from a PC in the same subnet, but it fails, the first step to resolve the problem is to navigate to Network and Flows > Network Management > Interfaces and enable the Bl interface. By default, the Bl interface is disabled after the Install wizard. You need to enable it and assign it to an External Zone, which is a logical grouping of interfaces that defines the security and routing policies for the external network

Correct Answer: D

The Avaya Session Border Controller for Enterprise (ASBCE) provides an integrated (local) WebLM server that can be used to install and manage licenses for the ASBCE server. The local WebLM server is only supported in a single-server hardware- based deployment, which is a deployment where the ASBCE server runs on a dedicated hardware appliance, such as an Avaya SBCe 1U or 2U server. In this deployment, the local WebLM server runs on the same hardware appliance as the ASBCE server and can be accessed using the ASBCE web interface or CLI. The local WebLM server can store up to 10 license files and can handle up to 5000 concurrent sessions.

Correct Answer: A

To trace SIP messages exchanged during a Remote Worker registration in real-time, you can use the tracesbc CLI tool on the Avaya Session Border Controller for Enterprise (ASBCE). The tracesbc tool is used to capture and display SIP messages and media statistics for calls that traverse the ASBCE server. You can use various filters and options to specify which calls or messages you want to trace. For example, you can filter by source or destination IP address, port, protocol, or call ID. You can also specify how long you want to run the trace and how many messages you want to display. The tracesbc tool can help you troubleshoot and diagnose issues with Remote Worker registration and call setup

Correct Answer: B

The tracePS CLI tool is a command-line interface tool that allows you to capture and analyze XMPP traffic between Avaya Aura Presence Services and other XMPP servers or clients. You can use this tool to troubleshoot issues related to presence, instant messaging, federation, or integration with third-party applications. You can also use this tool to generate reports on XMPP traffic statistics, such as message count, message size, message type, and message direction1

Correct Answer: D

To access the TSAPI Test from the Application Enablement Services (AES) menu, you need to select Utilities. The TSAPI Test is a basic application for making a call using TSAPI, which is a high-level API for CTI applications based on CSTA

I standard. TSAPI allows access to the third party call control capabilities of CM through AES. The TSAPI Test application can be used to verify that the TSAPI client is correctly installed and working on AES. If the TSAPI Test application fails

to make the call, an error message is provided to aid in troubleshooting the cause of the failure. To access the TSAPI Test from the AES menu, you need to follow these steps:

Log in to the web interface of AES using your username and password.

Click on Utilities on the left side menu.

Click on TSAPI Test under Utilities.

Enter the parameters for making a call, such as device name, destination number, user ID, and password.

Click on Make Call.

Correct Answer: D

A Survivable Communication Manager (CM) is a Communication Manager instance that provides local call processing and trunking capabilities for remote sites or branches in case of a WAN outage or loss of connectivity with the core servers. A Survivable CM monitors thestatus of the main CM by sending and receiving heartbeat messages at regular intervals. A heartbeat message is a SIP OPTIONS request that tests the availability of the main CM. If the Survivable CM does not receive a response to its heartbeat message within a specified timeout period, it assumes that the main CM is down and triggers a failover process. During the failover process, the Survivable CM accepts IP phone registration requests from the local endpoints and puts the configured IP trunks in a working condition, allowing the remote site or branch to continue making and receiving calls
