The Avaya Session Border Controller for Enterprise (ASBCE) certificate management is a feature that allows you to install, manage, and renew certificates for the ASBCE server. Certificates are used to authenticate and encrypt the

communication between the ASBCE server and other entities, such as endpoints, servers, or service providers. The following statements about the ASBCE certificate management are true:

It allows using a default server certificate for up to one year after the installation:

The ASBCE server comes with a default self-signed server certificate that can be used for testing or demonstration purposes. The default server certificate is valid for one year from the date of installation. After one year, the default server

certificate expires and needs to be replaced with a valid certificate from a trusted Certificate Authority (CA).

It supports both the Root and Intermediate Certificate Authority (CA) certificates:

The ASBCE server supports installing both the Root and Intermediate CA certificates, which are used to verify the identity and trustworthiness of other certificates. A Root CA certificate is a certificate that is issued by a trusted authority and is

self-signed. An Intermediate CA certificate is a certificate that is issued by a Root CA or another Intermediate CA and is used to sign other certificates. The ASBCE server can store up to 10 Root CA certificates and up to 10 Intermediate CA

certificates.

Correct Answer: B

The Avaya Session Border Controller for Enterprise (ASBCE) requires licenses to support different types of services, such as SIP Trunking or Remote Worker. The ASBCE licenses are based on the number of concurrent sessions that are handled by the ASBCE server. There are two types of licenses: standard services licenses and advanced services licenses. A standard services license is required for each SIP Trunking session, which is a session between the ASBCE server and a SIP service provider. An advanced services license is required for each Remote Worker session, which is a session between the ASBCE server and a remote endpoint, such as an IP phone or a softphone. Therefore, if the customer plans to have 50 SIP Trunks and100 Remote Workers supported by the ASBCE, they will need 50 standard services licenses and 100 advanced services licenses.

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: B

The initTM -f command is used to initialize the trust management between the Avaya Breeze?server and the Avaya Aura System Manager. This command requires an enrollment password that is configured in the System Manager web interface, under Security > Enrollment Password. The enrollment password has a validity period that can be set by the administrator. If the enrollment password has expired, the initTM -f command will fail. Therefore, before running the initTM -f command, you should verify that the enrollment password is configured and valid12

Correct Answer: D

When planning the Avaya Session Border Controller for an Enterprise (ASBCE) deployment, a good practice to adopt is to name interfaces consistently, for example, Al as "Internal" or "Private" for connectivity to the Call Server. The ASBCE server has four network ports that can be configured as logical interfaces with different IP addresses, subnet masks, gateways, and VLAN IDs. The logical interfaces are named Al, A2, Bl, and B2. A good practice is to use a consistent naming convention for the interfaces that reflects their purpose and function. For example, you can name Al as "Internal" or "Private" because it connects the ASBCE server to the internal network and the Call Server. Similarly, you can name Bl as "External" or "Public" because it connects the ASBCE server to the external network and the Internet. This naming convention can help you avoid confusion and errors when configuring the interfaces and assigning them to zones.

To associate the Avaya Call Park and Page snap-in to an Avaya Workplace Client, you need to perform the following key configuration steps: Add a Service Profile: A Service Profile is a set of parameters that defines the features and capabilities of a user or device in System Manager. You need to create a Service Profile for the Call Park and Page snap-in, under Users > User Management > Service Profiles. In the Service Profile, you need to specify the name, type, domain, and SIP Entity of the Call Park and Page snap-in. You also need to enable the Call Park feature and configure the Call Park activation and deactivation feature codes1 Configure a Call Park activation and deactivation feature code: A feature code is a numeric sequence that activates or deactivates a specific feature on Communication Manager. You need to configure a Call Park activation and deactivation feature code on Communication Manager, using the change feature- access-codes command. The Call Park activation feature code allows a user to park a call on a specified extension, while the Call Park deactivation feature code allows a user to retrieve a parked call from any extension2

Correct Answer: D

Avaya Aura Presence Services uses different ports for different purposes. Port 5222 is used by endpoints like Avaya one-X?Communicators, Avaya Equinox? or Avaya IXTM Workplace to establish client-to-server XMPP connections with the Presence Services snap-in on the Avaya Breeze?server. Port 5269 is used for server-to-server XMPP connections with the third-party XMPP servers, such as Google Talk or Jabber. These ports enable the presence and instant messaging features for the users34

Correct Answer: A

To enable IM and Presence for an Avaya Aura user, you need to edit the Communication Profile of the user in System Manager, under Users > User Management > Manage Users. In the Communication Profile tab, you need to assign an Avaya Presence/IM handle to the user, which is a unique identifier that follows the format username@domain.com. You also need to enable and configure the Presence profile for the user, which specifies the Presence Services snap-in that will provide presence and instant messaging features for the user.

Correct Answer: B

In the Avaya Session Border Controller for Enterprise (ASBCB) Multi-Server/ HA deployments, you can access the tracesbc tool that displays SIP messages in real-time as they pass through the ASBCE from the SBC component/ device command line via SSH session using PuTTY. A Multi-Server/ HA deployment is a deployment where two or more ASBCE servers are deployed in a pair or cluster, providing redundancy and scalability for the ASBCE server. Each ASBCE server consists of two components: the EMS component and the SBC component. The EMS component is responsible for managing and monitoring the ASBCE server, while the SBC component is responsible for processing and routing the SIP traffic. The tracesbc tool is a CLI tool that runs on the SBC component and captures and displays SIP messages and mediastatistics for calls that traverse the ASBCE server. You can use PuTTY, which is a terminal emulator application, to establish an SSH session with the SBC component and run the tracesbc tool from the command line.

Correct Answer: C

When registering as a Remote Worker via the Avaya Session Border Controller for Enterprise (ASBCE), you should configure the ASBCE External (Public) Interface IP address allocated for Remote Workers in the Server List of the Avaya one-X?Communicator. The ASBCE External (Public) Interface is the interface that connects the ASBCE server to the public Internet and allows communication with external entities, such as Remote Workers or SIP service providers. The ASBCE server acts as a proxy for the Remote Workers and handles the SIP registration and call signaling with the Avaya Aura Session Manager (SM). Therefore, you need to specify the ASBCE External (Public) Interface IP address as the SIP server address in the Avaya one-X?Communicator settings
