From a remote worker’s SIP Endpoint connected via Mobile Workspace, which tool is used to trace the successful way through Avaya Session Border Controller for Enterprise (SBCE) of an Invite message?

traceRT
traceSM
traceMW
traceSBC

Correct answer: B

Explanation:

traceSM is an interactive perl script that allows an administrator to capture, view, and save call processing activity on a Session Manager. While not as powerful or versatile as wireshark, traceSM is absolutely essential when it comes to working with Avaya SIP. First off, it allows you to view SIP messages even if they have been encrypted with TLS. Incorrect Answers:D: traceSBC is a Perl script that is run from a PuTTY or TuTTY session connected to the SBC’s Management (M1) IP address. It is used to monitor sessions.References: https://andrewjprokop.wordpress.com/2014/06/02/a-necessary-guide-to-the-avaya-tracesm-utility/

The provisioning script automatically runs as part of the first boot-up of the Avaya Session Border Controller for Enterprise (SBCE). During this process you assign the Management IP address to the SBCE. You browse to the Element Management System (EMS) to continue to install the SBCE.

On the System Management > Devices web page, which status does the SBCE display before the Install link is clicked?

Ready
Provisioned
Registered
Commissioned

Correct answer: C

To watch Avaya Session Border Controller for Enterprise (SBCE) messages in real time as they pass through the SBCE, which tool on the SIP command line do you use?

traceSBC
traceSM –m
traceTOOL
trace

Correct answer: A

Explanation:

The tcpdump tool is the main troubleshooting tool of Avaya SBCE, which can capture network traffic. Using tcpdump is a reliable way to analyze the information arriving to and sent from the SBC. However, tcpdump has its own limitations, which can make troubleshooting difficult and time consuming. This traditional tool is not useful in handling encrypted traffic and real-time troubleshooting. The traceSBC tool offers solutions for both issues. In Real-time mode, traceSBC must be on active Avaya SBCE. traceSBC is started without specifying a file in the command line parameters. The tool automatically starts processing the log files. The live capture can be started and stopped anytime without affecting service.

On Avaya Session Border Controller for Enterprise (SBCE), which two ways can be used to view System Logs? (Choose two.)

from CLI execute cat > var > log > Avaya > syslog
from System Manager web GUI > Alarms and Events
from CLI execute cat archive > syslog > ipcs.log
from EMS web GUI SBCE Dashboard access Logs > System Logs

Correct answer: CD

Explanation:

C: Call Trace data are written to this location:– /archive/syslog/ipcs/octeon.log D: Viewing system logsProcedure Log on to the EMS web interface with administrator credentials. Select the Logs option from the toolbar, and click the System Logs menu. The system displays the Syslog Viewer screen. On this screen, you can specify criteria in the Query Options section to filter the results displayed. In the Start Date and End Date fields, filter the results displayed in a search report to fall within starting and ending dates and times. In previous Avaya SBCE Syslog Viewer windows, there were four separate fields: Start Date, Start Time, End Date, and End Time.References: Troubleshooting and Maintaining Avaya Session Border Controller for Enterprise (December 2015), page 21Avaya Aura Session Border Controller Enterprise Implementation and Maintenance (2012), page 478

In the Avaya Session Border Controller for Enterprise (SBCE), before a traffic carrying Network Interface (A1 or B1) can be pinged, to which state do you have to toggle the status on Device Specific Settings > Network Management / Interfaces?

Enabled
In-Service
Accept Service
Active

Correct answer: A

Explanation:

Commission the SBC—SBC Configuration 1. The A1 and B1 interfaces display on the Network Configuration tab: 2. Click on the Interface Configuration tab: 3. Click the Toggle link for both the A1 and the B1 interfaces. The Administrative Status for both A1 and B1 changes to Enabled: References: Avaya Aura Session Border Controller Enterprise Implementation and Maintenance (2012), page 203

How many Server Flows and/or Subscriber Flows are required for SIP Trunking?

one Subscriber Flow and two Server Flows
a minimum of two Subscriber Flows
one Subscriber Flow and one Server Flow
a minimum of two Server Flows

Correct answer: A

Explanation:

Two types of flows need to be defined for the proper routing of SIP messages from and to the endpoints and the SIP server. Server Flows – Routing destination sent by SIP server (Session Manager). Subscriber Flows – Routing destination sent by SIP endpoints. Example, Server Flows: References: Avaya Aura Session Border Controller Enterprise Implementation and Maintenance (2012), page 540, 546

In Avaya Session Border Controller for Enterprise (SBCE) 7.x, you need to download the 46xxsettings.txt file to a Remote Worker device.

What needs to be configured under DMZ Services > Relay Services?

Application Relay and File Transfer
Reverse Proxy
Application Relay
Application Relay and Reverse Proxy

Correct answer: C

Explanation:

Relay Services are used to define how file transfers (e.g., for phone firmware upgrades and configuration), are routed to the Remote Worker endpoints.

When planning the Avaya Session Border Controller for Enterprise (SBCE) for SIP Trunking, what is a good practice to adopt?

Name Interfaces consistently, for example, A1 for Internal network to Call Server and B1 for external to Trunk Server.
Name all internal and external interfaces exactly the same.
Use the same IP address on both, internal and external sides of the network.
Use one Avaya Session Border Controller for Enterprise on the internal and external sides of the network.

Correct answer: A

Explanation:

Use the same interface mapping throughout! Examples in this section use:A1 as the internal interface (to the call server) B1 as the external interface (to the trunk server) References: Avaya Aura Session Border Controller Enterprise Implementation and Maintenance (2012), page 304

Use the same interface mapping throughout! Examples in this section use:
