Avaya ACIS-7130 71300X Questions & Answers

• Question 21:

  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.

  Correct Answer: B

  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.

• Question 22:

  What identifies that the Avaya BreezeTM server is using Identity Certificates that have been signed by Avaya Aura System Manager (SMGR)?

  A. if the Issuer Name states "O=AVAYA, OU=MGMT, CN= System Manager CA" for the Security Module SIP Identity Certificate

  B. if the replication status is showing `Synchronized' with a green background color

  C. if a successfully installed WebRTC snap-in is used

  D. if the Entity Link between Avaya Aura Session Manager (SM) and Avaya BreezeTM server is up

  Correct Answer: A

• Question 23:

  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).

  Correct Answer: B

  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.

• Question 24:

  WebRTC is used for which type of calls?

  A. video calls only

  B. calls originated from internal web browsers only

  C. calls originated from external web browsers only

  D. calls originated from internal and external web browsers

  Correct Answer: D

  The Avaya WebRTC Snap-in enables users inside or outside the Enterprise to make a secure call from their web browser to any endpoint to which Avaya Aura can deliver calls.

• Question 25:

  Which statement about WebRTC and Media Resources is true?

  A. WebRTC does not use any Media Resources since it only handles Text-Chat sessions.

  B. WebRTC relies on the Avaya Aura Media Server (AAMS) to convert the WebRTC media stream to a SIP media stream.

  C. WebRTC uses its own embedded proprietary technology to handle and process Media Packets.

  D. WebRTC uses Media Resources from a Hard-Based Media Gateway controlled by Avaya Aura Communication Manager (CM).

  Correct Answer: B

  The Avaya Media Server can translate WebRTC media into a SIP media stream. References: http:// www.avaya.com/blogs/archives/2014/10/an-introduction-to-the-avaya-webrtc- snap-in.html

• Question 26:

  Which three statements about Avaya BreezeTM are true? (Choose three.)

  A. It allows application developers to quickly add new capabilities to their Avaya solutions.

  B. It is used by Avaya, Partner, and Enterprise Developers.

  C. It does not require a license.

  D. It was formerly called Collaboration POD but has been renamed to Avaya BreezeTM.

  E. It is a development platform that enables rapid development for applications that are targeted to meet a customer's communications needs.

  Correct Answer: ABE

  Avaya Breeze provides a virtualized and secure application platform where Java programmers can develop and dynamically deploy advanced collaboration capabilities that extend the power of Avaya Aura. Customers, partners, and Avaya organizations can rapidly develop snap-ins and applications that are deployed on Avaya Breeze.

• Question 27:
