Correct Answer: B

If the Avaya Session Border Controller for Enterprise (ASBCE) does not trust the Certificate Authority (CA) that signed the WebLM server identity certificate, you can use the sbceconfigurator.py fix-weblm-cert command issued from the EMS CLI to fix the trust issue. The WebLM server is a web-based licensing application that manages licenses for various Avaya products, such as Communication Manager, Session Manager, Presence Services, or Breeze Platform. The WebLM server uses an identity certificate to authenticate itself to other entities that communicate with it using HTTPS or REST APIs. The identity certificate is signed by a CA, which is an entity that issues and verifies certificates. The ASBCE server needs to trust the CA that signed the WebLM server identity certificate in order to communicate with it securely and obtain licenses from it. If the ASBCE server does not trust the CA, you can use the sbceconfigurator.py fix-weblm-cert command to install the CA certificate on the ASBCE server and establish trust with it. The sbceconfigurator.py tool is a Python script that runs on the EMS component of the ASBCE server and performs various configuration tasks. The EMS component is responsible for managing and monitoring the ASBCE server. You can access the EMS CLI using SSH or Telnet and run the sbceconfigurator.py tool from there.

Correct Answer: D

Before obtaining a server identity certificate from a Certificate Authority (CA) for the installation on the Avaya Session Border Controller for Enterprise (ASBCE), you need to generate a Certificate Signing Request (CSR). A CSR is a file that contains information about the identity and public key of the ASBCE server, as well as a digital signature that proves the ownership of the public key. A CSR is used to request a server identity certificate from a CA, which is an entity that issues and verifies certificates. The CA will check the information in the CSR and issue a server identity certificate that contains the same information and public key, as well as the CA's signature and validity period. The server identity certificate is used to authenticate the ASBCE server to other entities that communicate with it using HTTPS or SIP over TLS. To generate a CSR for the ASBCE server, you can use tools such as OpenSSL or Keytool, or use the ASBCE web interface or CLI.

Correct Answer: BDE

Avaya Breeze?is a development platform that enables rapid development for applications targeted to meet a customer's communications needs. It is used by Avaya, Partner, and third-party developers to create and deploy snap-ins, which are modular software components that provide specific functionality or features. Avaya Breeze?allows application developers to quickly add new capabilities to their Avaya solutions, such as voice, video, messaging, presence, collaboration, and analytics.

Correct Answer: D

To allow the Avaya one-X?Communicator to subscribe to the Avaya Aura Presence Services, you need to enter the Avaya Breeze?server Security Module IP Address or FQDN in the IM and Presence / Server field of the one-X? Communicator. The Security Module (SM100) is a component of the Avaya Breeze?server that provides security and encryption functions for SIP signaling and media. The SM100 IP address or FQDN is used by the one-X?Communicator to communicate with the Presence Services snap-in on the Avaya Breeze?server and receive presence and instant messaging features.

Correct Answer: A

When configuring the Avaya Call Park and Page snap-in, the Call Park Extension Group attribute is used to specify the extensions that can be used to park calls. The format of the Call Park Extension Group attribute is as follows:

():,,... The location ID is a numeric value that identifies the location where the Call Park and Page snap-in is deployed. The number of digits is the number of digits in each extension.

The extensions are the actual extensions that can be used to park calls. For example, 3(1):4000,4001,4002 means that the Call Park and Page snap-in is deployed in location 3, each extension has one digit, and the extensions are 4000,

4001, and 40021

Correct Answer: B

The CLI tool that is used to trace messages in real-time as they pass through the Avaya Session Border Controller for Enterprise (ASBCE) is tracesbc. The tracesbc tool is a CLI tool that runs on the SBC component of the ASBCE server and captures and displays 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 SIP registration and call setup.

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

When deploying Avaya Aura Presence Services as a snap-in on a single Avaya Breeze?server, you need to create two SIP Entities for the same Avaya Breeze?server Security Module IP address or FQDN in System Manager. One SIP Entity is used for the Avaya Breeze?platform itself, and the other SIP Entity is used for the Presence Services snap-in. The type of the SIP Entity determines how Session Manager routes SIP messages to the Avaya Breeze?server. The type Avaya Breeze?indicates that the SIP Entity is a generic Avaya Breeze?server that canhost any snap-in. The type Presence Services indicates that the SIP Entity is a specific Avaya Breeze?server that hosts the Presence Services snap-in12

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
