The Survivable Communication Manager (CM) is configured on the System Manager (SMGR) as a Managed Element. A Managed Element is an entity that can be managed by SMGR, such as Communication Manager, Session Manager, Presence Services, or Breeze Platform. A Survivable 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 can be deployed on an S8300D server or on an external server such as Dell R620/R630 or HP DL360 G8/G9. To configure a Survivable CM as a Managed Element on SMGR, you need to specify its name, type, IP address, login credentials, and security settings56

Correct Answer: C

With Dynamic Licensing configured in the Avaya Session Border Controller for Enterprise (ASBCE), the ASBCE will issue a request to the WebLM server to allocate additional licenses based on the Fetch Count value when the percentage of free (available) standard sessions licenses drops below 30% (Low Watermark). Dynamic Licensing is a feature that allows the ASBCE to dynamically allocate and release licenses from a pool of licenses managed by the WebLM server. The Fetch Count value is a parameter that specifies how many licenses are requested from the WebLM server at a time. The Low Watermark value is a parameter that specifies the threshold percentage of free licenses that triggers a request for more licenses from the WebLM server. The High Watermark value is a parameter that specifies the threshold percentage of free licenses that triggers a release of unused licenses to the WebLM server

Correct Answer: C

In some deployments, you can enable a feature called "Stream Users Over Transport Link" in the Signaling Interface used for the Avaya Aura Session Manager (SM) on the Avaya Session Border Controller for Enterprise (ASBCB). This feature allows reusing the same TCP connection to SM for all SIP messages related to Remote Workers registered with SM through ASBCB. A Signaling Interface is a configuration object that defines how ASBCB handles SIP signaling with other entities, such as endpoints or servers. A Signaling Interface can include parameters such as source and destination IP addresses, ports, protocols, encryption modes, authentication modes, and timers. The "Stream Users Over Transport Link" parameter is an option that can be enabled or disabled in the Advanced tab of the Signaling Interface configuration screen. When this option is enabled, ASBCB will use the same TCP connection to SM for all SIP messages related to the same Remote Worker. This can reduce the number of TCP connections and improve the performance and scalability of ASBCB and SM.

The output from the show mgc command (issued on a G430/G450 Gateway CLI) can indicate whether the G430/G450 is operating as an Internet Friendly (Edge) Gateway or an Enterprise Gateway. An Internet Friendly (Edge) Gateway is a device that provides secure and reliable connectivity between endpoints on different networks, such as the public internet and a private enterprise network. An Enterprise Gateway is a device that provides connectivity between endpoints on the same network, such as a LAN or a WAN. The show mgc command displays information about the Media Gateway Controller (MGC), which is the entity that controls the media gateway functions of the G430/G450, such as call processing, routing, and signaling. The MGC can be an Avaya Communication Manager (CM) server or an Avaya Session Border Controller for Enterprise (ASBCE) server. The output from the show mgc command includes these fields: Management Link Mode: This field indicates how the G430/G450 communicates with the MGC for management purposes, such as configuration, monitoring, and troubleshooting. The possible values are Direct or Tunnelled. Direct means that the G430/G450 communicates with the MGC using a direct IP connection over TCP port 5022. Tunnelled means that the G430/G450 communicates with the MGC using a tunnel over TCP port 2944 and secured using TLS. This mode is used when the G430/G450 operates as an Internet Friendly (Edge) Gateway and communicates with ASBCE as the MGC.

H.248 Link Mode: This field indicates how the G430/G450 communicates with the MGC for media gateway control purposes, such as controlling media streams, allocating resources, and creating connections. The possible values areEGW or

IFG. EGW means that the G430/G450 communicates with the MGC using H.248 protocol over UDP port 2944. This mode is used when the G430/G450 operates as an Enterprise Gateway and communicates with CM as the MGC. IFG means

that the G430/G450 communicates with the MGC using H.248 protocol over TCP port 2944 and secured using TLS. This mode is used when the G430/G450 operates as an Internet Friendly (Edge) Gateway and communicates with ASBCE

as the MGC.

H.248 Link Status: This field indicates whether the H.248 link between the G430/G450 and the MGC is up or down, and whether it is encrypted or not. The possible values are UP/Encrypted, UP/Unencrypted, DOWN/Encrypted, or DOWN/

Unencrypted. UP means that the H.248 link is established and functional. DOWN means that the H.248 link is not established or not functional. Encrypted means that the H.248 link is secured using TLS encryption. Unencrypted means that

the H.248 link is not secured using TLS encryption. Therefore, to determine whether the G430/G450 is operating as an Internet Friendly (Edge) Gateway or an Enterprise Gateway, you can look at these two fields in the output from the show

mgc command:

If the H.248 Link Mode displays IFG, it means that the G430/G450 is operating as an Internet Friendly (Edge) Gateway and communicating with ASBCE as the MGC using H.248 over TCP port 2944 and secured using TLS. If the H.248 Link

Status displays UP/Encrypted, it means that the G430/G450 is operating as an Internet Friendly (Edge) Gateway and communicating with ASBCE as the MGC using a secure and functional H.248 link.

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.
