The Avaya WebRTC solution uses the web intensively to make media calls from a standard web browser in the internet, into internal and secure communication premises in the enterprise.
Which statement about security between the Enterprise-edge and those standard Web browsers in the internet is true?
- A. A trust relationship based on certificates must be built to make WebRTC work.
- B. No trust relationship exists between enterprise edge security and web browsers; therefore, the security strategy is based on an Authorization Token instead.
- C. There must be a VPN connection between the Web Browser and the Enterprise-edge to build a WebRTC link.
- D. WebRTC only works within the Enterprise network. External Web Browsers must connect through an Avaya Session Border Controller for Enterprise (SBCE) via a SIP trunk.
Answer : B
Explanation:
Validation of the authorization token.
The WebRTC Snap-in will validate the authorization token created and encrypted by the web server. If the snap-in can decrypt the token and ensure that the time stamp is valid, it knows that the incoming HTTP request is valid. The time stamp will usually be short lived; on the order of 5-10seconds to protect against reply attacks.

Answer : B
Explanation:
Dedicated AxC/Directory server: A physical server that manages notification capabilities and the LDAP database and provides communications between application servers and the thirdparty storage server. This server also stores user properties and name and greeting recordings.
Not all configurations require a dedicated AxC/Directory server because the AxC/Directory role runs on the Avaya-provided message store. You only need a dedicated AxC/Directory server for:

Answer : B
Explanation:
Enabling AE Services refers to administering the transport link between Communication
Manager and AE Services.
Procedure -
1. Type change ip-services. Communication Manager displays the IP SERVICES form
2. Complete Page 1 of the IP SERVICES form
3. Complete Page 3 of the IP SERVICES form as follows.
a. In the AE Services Server field, type the name of the AE Services server b. In the Password field, create a password.
This is the password that the AE Services administrator must set on the AE Server

Which statement describes Cross-Origin Resource Sharing (CORS)?
- A. It allows for signaling-groups to be used by more than one trunk-group.
- B. It is a W3C specification that allows cross-domain communication from the browser.
- C. It is making DSP resources available regardless of the originating location of a call.
- D. It is a network setup by which an Avaya Aura® Media Server (AAMS) can be used by more than one Avaya Aura® Communications Manager (CM).
Answer : B
Explanation:
Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources
(e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos.
Note on the History of CORS:
Cross-origin support was originally proposed by Matt Oshry, Brad Porter, and Michael
Bodell of Tellme Networks in March 2004 for inclusion in VoiceXML 2.1 to allow safe cross- origin data requests by VoiceXML browsers.
In May 2006 the first W3C Working Draft was submitted. In March 2009 the draft was renamed to "Cross-Origin Resource Sharing" and in January 2014 it was accepted as a
W3C Recommendation.

In Avaya Session Border Controller for Enterprise (SBCE) 7.x, which two configuration screens must be configured for Personal Profile Management (PPM) to be successfully downloaded to an Avaya SIP Telephone (AST)? (Choose two.)
- A. PPM Services Mapping Profile
- B. Application Relay
- C. File Transfer
- D. Reverse Proxy
Answer : A,B
Explanation:
B: Application relays function as port forwards. Different clients require different application relays.
A: An Avaya SIP phone downloads and processes a configuration file, sends out a slew of
SUBSCRIBE messages, and uses something called Personal Profile Manager (PPM).
Note: The PPM is a software module that runs as part of an Avaya Session Manager. It consists of a series of web services that phones use to retrieve and manage SIP related user data.

By default, which Codec does Avaya Aura® Messaging (AAM) support?
- A. G.726
- B. G.722
- C. G.711
- D. G.729
Answer : C
Explanation:
You must configure the Messaging system to use the G.711 encoding format.
Note: The G.711 format provides the highest audio quality especially when voice networks use multiple encodings and decodings. Avaya requires that you use the G.711 encoding format in Messaging systems that support TTY devices.
The G.711 encoding format uses a higher encoding rate than GSM. The G.711 encoding format therefore produces larger files and requires more storage space for messages.
Messaging provides customers with adequate storage space for message playback and networking.
