1.Avaya Breeze is Avaya’s new Collaboration Environment and Engagement Platform (EDP). What statement correctly describes Avaya Breeze?

• A platform for Avaya, partners and enterprises to build and deploy collaboration applications.

Подсказка: Avaya Breeze is a development and execution platform for creating rich, omni-channel real-time communications applications.

2.What component provides SIP load balancing for multiple nodes in an Avaya Breese high availability installation?

• Avaya Aura Session Manager

Подсказка: For SIP traffic coming into Avaya Breeze, Session Manager serves as the load balancer.

SIP high availability is possible with Avaya Breeze by administering a cluster of Avaya Breeze servers and connecting each member of the cluster to each Session Manager.

You can then route users of a service to the cluster rather than to a specific Avaya Breeze server so it is likely that at least one will be available.

For Avaya Breeze the HTTP Load Balancer “routes” traffic to the Avaya Breeze servers in the cluster. It then follows a round-robin distribution method. If the Avaya Breeze server is offline then the Avaya Breeze server sits in an inactive pool for 15 seconds and then requests are sent to a different Avaya Breeze server in the cluster.

Primary and Secondary Balancers heartbeat each other. In case of a Primary server outage, the secondary server assumes usage of the Cluster IP and begins balancing the HTTP traffic. Once it is back online, the Primary Avaya Breeze server resumes control. In the event of a Primary server failure, a MAJOR alarm is raised.

3.Which three Avaya Breeze Snap-in scenarios require an AAMS? (choose three)

• When and application needs to play an announcement
• When 2-Party Make Call (Call-me / Call-you) is included in application
• When there is a need to support Text to Speech

Подсказка: The Avaya Aura Media Server delivers advanced multimedia processing features to a broad range of products and applications. One design concern is do we need to add an Avaya Aura Media Server to the configuration for a solution. So when is an Avaya Aura Media Server required for an Avaya Breeze Snap-in or application?

Here are some obvious scenarios: Then and application needs to play an announcement to one or both parties in a call, when there is a need too collect DTMF digits, when there is a need to support Real-Time Speech, when there is a need to support Text to Speech, which, by the way, requires Nuance, or when there is a need to support Automatic Speech Recognition, which also requires Nuance.

And here are some less obvious scenarios: Then the WebRTC Snap-in is used, when 2-Party Make Call (Call-me / Call-you) is included in application, when Sequential Forking (Find-me / follow-me) is used in the application, and when Flexible Call Leg Control (Drop one participant, add another) is used in an application.

4.In addition to each user requiring a named user license, which design rule applies to an Avaya Breeze solution with or without an Avaya Aura Media Server (AAMS)?

• For a high availability deployment with AAMS, both Breeze and AAMS must be high availability.

Подсказка: Based on the size of the customer and the requirement for high availability, to support the WebRTC, Engagement Designer, Call Blocker and Smart Caller ID Outbound Snap-ins we need the following: 2 Avaya Breeze virtualized instances in an HA configuration. 2 AMS virtualized instances in an HA configuration We will place the additional Avaya Breeze and AMS instances in Venice.

9.An Avaya Aura customer wants to add Click-to-call to their web site. The customer has: 1) three survivable remote sites supporting SIP endpoints 2) Presence deployed on Avaya Breeze servers instances in a high availability configuration at their main site and 3) Avaya Aura Conferencing (AAC) servers and Avaya Aura Media Servers (AAMS) supporting AAC at their main site. What is needed to integrate Click-to-Call from their website?

• They need to install additional Avaya Breeze instances and add the WebRTC Snap-in to the new Avaya Breeze instances.
• They need to install additional Avaya Breeze instances and add the Smart Caller ID Outbound Snap-in to the new Avaya Breeze instances. No AAMS instances are needed.
• They need to add the WebRTC Snap-in to the existing Avaya Breeze instances and utilize the existing AAMS servers. (не уверена)
• They need to install additional Avaya Breeze instances and add the WebRTC Snap-in to the new Avaya Breeze instances. They also need to install new AAMS instances.

Подсказка: The Snap-in takes advantage of WebRTC to deliver a mobile experience across a wide array of iOS, Android™, and WebRTC-supported browsers. It integrates “click-to-call” or video chat directly back to agents on Avaya Aura ® Call Center Elite using Avaya one-X Agent. Developers can build services that tap into rich context for intelligent routing and personalized real-time engagement with Avaya Breeze Context Store and Work Assignment Snap-ins.

WebRTC adds real-time communications to any website making customer contact and support easier and giving those without immediate access to a telephone another way to connect. It allows Click-to-Call. WebRTC is available as a Snap-in on Avaya Breeze

• Support for external ‘Click to Call’ applications from a website with an audio path.
• Inclusive in the integration is relevant payload with the call that can be used for contextual treatment by Context Store Snap-in.

With Avaya Breeze 3.2 we will offer a WebRTC Debug license that will allow an Engagement Designer Workflow to be tested with a single WebRTC call. This license is for non-production use and needs to be selected during the Avaya Once Source configuration. Until Jan-2017 please contact productops@avaya.com to activate this WebRTC Debug license.

10.In Avaya Aura environment, Avaya Breeze applications can function as sequenced applications. Sequenced applications are invoked by which Avaya Aura Component?

• Session Manager

Подсказка: With Sequenced Applications calls can be influenced before alerting the called party.

Logic can be inserted. The calling or called party IDs can be manipulated. We can play messages to individual participants or the entire call.

Sequenced Applications are invoked by Avaya Aura Session Manager on behalf of the originator of a SIP session and or on behalf of the terminator of a SIP session.

This diagram gives a simple illustration of the flow of a sequenced application.

The originating user initiates a call. The originating user could be a local user or a user coming in on a PSTN trunk. Session Manger routes the calling and called party ID to Communication Manager for processing. Communication Manger sends information to Session Manger indicating that the call needs to go to Avaya Breeze for additional processing. The Avaya Breeze applications adds it treatment to the call and returns it to Session Manager for termination processing to the Termination point. As these are SIP endpoints Direct Media is used for communications between the endpoints.

This same flow can apply to incoming or outgoing calls.

11.What is the deployment choice for Avaya Breeze 3.2 when not using Avaya Aura Presence Services?

• VMWare virtualized application

Подсказка: The Avaya Breeze Server license entitles a customer to 1 instance of a virtualized Avaya Breeze Server instance.

The server will only run on a customer’s provided VMware environment. There are no offers to provide a hardware appliance for general Avaya Breeze use. Avaya Aura 7.x Presence Services is offered on the Application Virtualization Platform (AVP) and leverages Avaya Breeze as its infrastructure. Presence Services on AVP uses a predefined VMware footprint which does not support the VCenter Agent at this time and cannot be used got general Avaya Breeze usage.

12.Which Avaya Engagement Designer component is installed as a Snap-in on an Avaya Breeze platform?

• Workflow Engine

Подсказка: Engagement Designer needs to be ordered as a separate line item from Avaya Breeze along with any other snap-ins purchased. Avaya Engagement Designer can be delivered along with Avaya Breeze and any other snap-ins ordered by the customer. Let’s talk a little about components of the Engagement Designer:

• Workflow Engine is installed as a snap-in on Avaya Breeze. It subscribes to Avaya Breeze events and executes the Workflow Instances for deployed Workflow Definitions.
• Workflow Definitions describe business processes used in your enterprise. You use Workflow Definitions to create complex, end-to-end communications-enabled business processes across mobile, collaboration and contact center applications.
• Workflow Instance is created each time a Workflow Definition is invoked by a triggering event.

Events that trigger a particular Workflow Definition are specified in the Start event.

13.Where is information stored to complete the action of the failed server in the event of a cluster node failure in an N+M Redundant Breeze solution?

• Data Grid

Подсказка: If any node in the cluster goes down the data grid contains information from that node and complete the actions that of that node. Each Avaya Breeze Cluster is N+M Redundant which supports multiple Avaya Breeze failures. Avaya Breeze takes over for each other by re-using the media paths for existing sessions, preserving existing call connections, sending INVITE is replaced to re-create the signaling paths, and Calls In-Queue for a contact center are preserved.

14.Which statement correctly describes a Snap-in?

• Applications, connectors and modular reusable code that can quickly create or integrate new capabilities into processes and applications.

Подсказка: A Snap-in is an Avaya Breeze application or connector extension that expands Avaya Breeze capabilities.

15.Which Statement correctly describes writing or developing Avaya Breeze Applications

• They can be written in Java or deployed using Avaya Engagement Designer.

Подсказка: Snap-ins may include such things as: complete out of the box communications applications, modular and re-usable APIs and SDKs for developers to mix and match in order to build their own unique applications. Snap-ins may also include media and application connectors.

Developers can create their own Snap-in applications in Java or non-Developer Business Analysts can use Avaya Engagement Designer workflow design capabilities to build communications enabled services and applications.

To reduce development time and cost, applications can be developed by “snapping in” applications, connectors or code from Avaya or 3 rd party developers.

16.Which Snap-ins support Avaya Breeze geo-redundancy?

• Context Store and Presence Snap-ins

Подсказка: From the standpoint of geo-redundancy for Snap-ins, currently only Context Store and Presence today support HA and Geo-Redundancy. They use the GigaSpaces WAN Gateway which synchronizes data between two data centers.

17.Which three tools are available through the Avaya Breeze Software Development Kit (SDK)? (choose three)

• Java application program interfaces (API)
• Sample Services
• Eclipse Integrated Development Environment (IDE) Integration.

• Avaya offers full depth and breadth of real-time communications functionality.

21. Which statement correctly describes the relationship between Avaya Breeze, Avaya Aura, Avaya Aura Media Server. Avaya Breeze can share AAMS instances with Avaya Aura Application ???

22. Which two sources of data arrive at the Start Event in an Avaya Engagement Designer Workflow? (choose two)

• An event administered in the Event Catalog
• A website or REST client

Подсказка: The data mapper manages the flow of data from the Start event through the different tasks of the Workflow Definition. The data arrives at the Start event from:

• An event administered in the Event Catalog
• An event created by the completion of another WFD
• A process created by a Create Process task
• Or a website or REST client

Start events have an associated schema that describes the available data.

23.Where is the Avaya Breeze Presence Services Snap-in installed?

• On the Core Platform Cluster

Подсказка: Clusters contain one or more nodes. You can have multiple instances of various cluster types. You can have from 1 to 35 Avaya Breeze servers and 1 to 5 Avaya Breeze nodes per cluster.

Avaya Presence services requires a dedicated Core Platform cluster which cannot be shared by other applications.

When Presence Services is deployed on its closed Core Platform cluster we have engineered this specific configuration to support up to 8 nodes in a cluster given its very controlled and well defined usage model.

24.Which Avaya Aura component must be upgraded to release 7.0.1 to support Avaya Breeze 3.2?

• System Manager

25.Which statement correctly describes the Avaya Breeze Engagement Call Control (ECC) Snap-in?

• ECC in an Avaya Breeze entitlement and requires Application Enablement Services (AES).

Вопрос с подковыркой, т.к. в будущем релизе Breeze (но непонятно каком, а в тексте ниже речь о 3.4) обещают опцию прямого соединения с CM без AES. Поэтому при сдаче экзамена хорошо бы проверить Product Offer Definition and Business Partner Proposition, если вдруг будут вопросы по новым релизам.

Подсказка: At this time the Engagement Call Control (ECC) Snap-in is an entitlement the Avaya Breeze offer.

The Engagement Call Control (ECC) Snap-in provides REST APIs for CTI style call control. The ECC Snap-in provides functional equivalency to the ACE SOAP Web Services 3 rd Party Call Control. ECC uses a protocol called Application Switch Adjunct Interface (ASAI) through the Application Enablement Services (AES) to hook into Communication Manager call processing. In a future release ECC will provide an option to use ASAI directly to communicate to CM without requiring AES. ECC has control and visibility of all CM calls including station to station, station to trunk, or trunk to station. With the RESTful Engagement Call Control snap-in you will be able to perform the following functions in Avaya Breeze 3.1:

• Make a call, cancel a call, answer a call, end a call
• Consult transfer, single step transfer
• Hold or Retrieve a call
• Set or cancel call forwarding
• Voice mail connector to Avaya Aura Messaging

The ECC Snap-in uses the call model provided by UCM (Unified Collaboration Model) and uses the DMCC (Device, Media and Call Control) client to communicate to AES (Application Enablement Services) through the Call Server Connector (CSC).

26. Scopia Connector requires integration with which release of Avaya Scopia?

• Scopia 8.3

Подсказка. Scopia Connector

• Allows services to send API requests to the Scopia Management Server (by using the Create Conference API)
• Requires integration to Scopia Solution 8.3.

27. Which Snap-ins can use Persistence Database or Cluster Database?

• Any Avaya or Avaya Presence Services (APS) developed Snap-in (проверить вариант Any 3rd Party Snap-in, Avaya Engagement Designer Snapin or Avaya Presence Service Snap-in)

Подсказка: Persistence Database (only available to select Avaya Snap-ins)

Avaya Breeze will introduce a database (DB) that can be used to store data for the cluster. Every cluster has one node designated as the Primary. All data access to snap-ins is provided from the Primary node. In multi-node clusters, the persistent DB is highly available (HA) because one other node that is not the primary node is designated as the standby node. The primary asynchronously streams transactions to the standby so that the standby has an in sync copy of the DB. If the primary fails or is taken down, the standby can take over as the primary quickly with very minimal data loss.

For release 3.1, the database can mirror GigaSpaces data grids, thus enabling select Avaya snap-ins that use GigaSpaces to benefit from persistent storage. The Engagement Designer and Presence Services snap-in can use it as a general purpose DB.

28. How many designer licenses does the Avaya Engagement Designer basic offer include? 1

Engagement Designer needs to be ordered as a separate line item from Avaya Breeze along with any other snap-ins purchased. Avaya Engagement Designer can be delivered along with Avaya Breeze and any other snap-ins ordered by the customer.

29. How many concurrent workflow instances does Avaya Engagement Designer Workflow Engine Support?

• 4200

Подсказка из Avaya Engagement Designer Reference Release 3.5 Issue 1 August 2018: Chapter 7: Performance Capacities • 4200 Workflow Instance (WFI) limit per cluster • 100 Workflow Definition (WFD) limit per cluster

Memory allocation Avaya Engagement Designer Release 3.5 has a minimum required memory allocation of 8 GB. Avaya Breeze disk size The minimum Avaya Breeze server disk size for Avaya Engagement Designer is 100 GB. In your VM machine properties, increase the provisioned size of the hard disk to 100 GB. See your VM documentation for additional information. Alternatively, if you are deploying Avaya Breeze using the Solution Deployment Manager (SDM), select profile 2b. This will eliminate the need to increase the disk size.

For additional information, see the Hardware requirements section of this document.

30.Which Avaya Breeze Snap-in provides Click-to-Call capabilities from a web page?

• WebRTC Snap-in

Подсказка: Purchasable snap-ins include: • Avaya Context Store Snap-in • Avaya Work Assignment Snap-in • Avaya WebRTC Snap-in • Avaya Real-Time Speech Snap-in

3.1.10. WebRTC Snap-in WebRTC Snap-in allows consumers ‘click to call’ capabilities from any supported browser by connecting an audio path along with the associated web page information to an agent supported off of Avaya Breeze.

31.Which configuration requires STUN or TURN servers with the Avaya WebRTC Snap-in?

• NATs are used под вопросом (ответила так)

(проверить Browsers do not have routable IP addresses)

Подсказка. STUN server address. The following IP address and port based on the enterprise network:

• If you use Avaya SBCE, the Avaya SBCE IP addresses and port.
• If web browsers are located outside the enterprise network, the external IP address.
• If web browsers are located within the enterprise network, the private IP address.
• If there are web browsers that are located outside and within the enterprise network, the external IP address.

The enterprise network must be connected to the external IP address of Avaya SBCE. The format of the IP addresses and ports that you enter must be address:port. Use comma (,) as a delimiter. The default STUN port is 3478. The default port must be accessible in the firewall.

Note

Avaya SBCE configured as a TURN/STUN server does not support NAT servers for WebRTC. To mitigate this lack of support for NAT servers, the external interface of Avaya SBCE must be configured with a public IP address. The TURN server relay address must be configured on the external interface of Avaya SBCE, which is connected to the external firewall of the enterprise DMZ. The external firewall provides Layer 3 security to the TURN relay address.

The enterprise gateway must be configured to send all data packets through the external firewall of DMZ. These data packets reach the Avaya SBCE external interface which is visible to public networks. WebRTC Snap-in does not support hiding the external interface IP address of Avaya SBCE from public networks.

Сервер STUN (Simple Traversal of User Datagram Protocol [UDP-протокол пользовательских датаграмм] через сервер NAT [транслятор сетевых адресов]) позволяет клиентам NAT (т.e. компьютерам за сетевым экраном) устанавливать сеансы связи с провайдером VOIP, находящимся за пределами локальной сети.

Сервер STUN позволяет клиентам находить свой адрес общего доступа, тип NAT, за которым они находятся и порт Интернета, связываемый NAT с конкретным локальным портом. Эта информация используется для настройки связи UDP между клиентом и провайдером VOIP и организации сеанса. Протокол STUN определяется стандартом RFC 3489.

Соединение с сервером STUN устанавливается через UDP-порт 3478, однако сервер предлагает клиентам выполнить проверку также и альтернативного IP и номера порта (у серверов STUN есть два IP-адреса). В RFC говорится, что выбор порта и IP является произвольным.

Что такое STUN и зачем он нужен?

Так случилось, что очень много пользователей сидят в интернете за NAT (Network Address Translation). Например, наш компьютер в локальной сети имеет IP-адрес 192.168.1.100. Адресов диапазона 192.168.x.x в Интернете быть не может (он зарезервирован для локальных сетей), и такой пакет к отправителю не вернется. Когда пакет из локалки уходит в интернет, NAT (обычно это часть функционала шлюза в интернет) подменяет в нем адрес отправителя на внешний (публичный) адрес NATа, например 1.2.3.4. Когда получатель пакета получит его и решит отправить ответ, то он пошлет его на внешний адрес NATа. А внутри себя NAT заменит адрес обратно на 192.168.1.100 и дошлет пакет компьютеру в локалку.

Чтобы знать, какой пакет какому компьютеру внутри прикрытой NATом сети предназначен, NAT подменяет еще и номер порта, и помещает его в таблицу соответствий номеров портов и внутренних адресов.

Вроде бы все работает прозрачно для сидящих за NATом компьютеров. Проблема возникает тогда, когда компьютеры сначала договариваются о передаче данных по одному протоколу, сообщая друг другу свои IP-адреса, через которые пойдет обмен (конечно, NAT про протоколы не знает, ему важны номера портов), а потом начинается собственно передача данных. Именно так происходит установление соединения в VoIP - договариваются хосты о соединении по SIP, сообщая друг другу адреса и номера портов для голосовых RTP-потоков по SDP, а обмен идет уже по RTP.

Компьютер с адресом 192.168.1.100 посылает VoIP-шлюзу во внешней сети свой адрес и порт, допустим, 192.168.1.100:40000. Шлюз после установления соединения начинает отправлять RTP поток… куда? Адрес-то левый! В итоге абонент в телефонной сети со стороны шлюза слышит голос из локалки, а его - не слышат. Типичный случай “one-way-voice”.

Поэтому компьютер в локальной сети должен сначала узнать свой внешний адрес и номер порта. Для этого в интернете существуют STUN-серверы. Упрощенно это выглядит так: компьютер из локалки посылает STUN-серверу пакет, тот его получает и отправляет обратно, запихнув внутрь адрес и номер порта, с которых он их получил. Дальше предпринимаются еще несколько действий для выяснения типа NATa, но это уже не так важно и хорошо описано в статье по ссылке выше.

Теперь дело техники: компьютер в локалке передаст в SDP не свой локальный адрес, а полученный через STUN. Путь пакетам уже «пробит» запросом к STUN-серверу (т.е. NAT установил соответствие локальный хост : порт ←→ внешний порт), поэтому входящие извне пакеты попадут в локалку и слышимость будет обоюдная.

• Ability to page individuals

Подсказки

Call Park and Page Snap-in provides the same Avaya Call Park and Page functionality provided by CS1000 using Avaya Aura core (CM, SM etc) via Avaya Breeze . While CM contains call park and retrieval functions (park retrieval on CM is often referred to as “Answer Back”), operation is slightly different from CS1000. This Snap-in will allow the current base of CS1000 customers to embrace Avaya Aura and retain the valuable park and paging operation while moving users or locations onto Avaya Aura as part of the CS1000 modernization effort. Doc ID: FAQ110942

Breeze: Is there a Breeze snap-in available that can emulate CS1000 Call Park and Page functionality to enable migrations to Communication Manager?

Yes, Avaya Call Park and Page Snap-in for Breeze provides enhanced call park capabilities for Avaya Aura Platform users and provides a familiar user experience for Avaya Communication Server 1000 users transitioning to the Avaya Aura Platform. Call Park and Page allows an operator to put incoming calls on hold in a queue while a page is sent to the needed person to call and pick up the call from another phone. Call Park and Page leverages existing paging systems for the operator to page out the park directory number, as well as existing audio source (music, announcements) to optionally provide audio to the parked caller.

The Call Park and Page Snap-in is a telephony feature on Engagement Development Platform.

With the Call Park and Page Snap-in:

• An attendant who parks the call from an attendant station or any other endpoint, can park a call to a fixed or dynamic Park Extension number.
• A paged retrieving party, for whom the intended call is intended, can dial the Park Extension number to connect with the caller.
• A paged retrieving party can dial the Park Extension number from any number within or outside the network.

After the attendant successfully parks a call, their endpoint displays the Park Extension number at which the system parks the call. The attendant who parked the call must then use existing notification or paging services to page the called party. The page informs the called party that a call is waiting at the Park Extension number. While the call is parked, the caller hears music or audio, if configured. The paged retrieving party can retrieve the call by dialing the Park Extension number from any number within or outside the network.

If the paged retrieving party does not respond within a configured time, the system sends the call back to the number that parked the call. You can then repark the call or press the asterisk key (*) after answering the call, and connect to the parked caller.

Call Park and Page architecture The Call Park and Page Snap-in obtains installation, update, and patching procedures from the Engagement Development Platform cluster. To upgrade, the customer deploys a new version of the Call Park and Page Snap-in.

Then the attendant dials a pilot number before parking a call, Avaya Aura Media Server plays an announcement. After the call is parked, the media resources, which provide music on hold, reside on Avaya Aura ® Media Server and are controlled by the Call Park and Page Snap-in.

The Call Park and Page Snap-in can share Avaya Aura Media Server resources with other snap-ins in the General Purpose, General Purpose Large, or Core Platform cluster.

However, the Call Park and Page Snap-in cannot share Avaya Aura Media Server resources with Communication Manager. Avaya Aura 7.0 onwards, Communication Manager can take advantage of Avaya Aura Media Server for the same purposes that it currently uses H.248 Media Gateways.

The Context Store Snap-in allows the capturing of every step of the customer journey with full 360 degree context.

In this example a customer experienced a login failure, sent an SMS to customer service who in turn sent an SMS with a password re-set link. These interactions where all placed in the Context Store. The customer then searched the web site for a new product issue and did not find an answer. They then sent an email to get an answer to the new product issue. When the customer places a call to resolve the issue, the customer service agent sees all of the interactions during the customer’s journey and is able to resolve the issue without having to ask the customer to repeat any of the history. This leaves the customer with a very good impression.
