If more than one Avaya Breeze™ node is available in the cluster, which statement about redundancy and load-balancing is true?

  1. IM clients point to any Avaya Breeze™ node SM100 IP address. The client is dynamically informed of alternate Avaya Breeze™ nodes in the cluster.
  2. The list of all Avaya Breeze™ nodes SM100 IP addresses must be configured in the client.
  3. The Cluster IP address is not used for Presence Services in 7.0. IM clients configure a FQDN instead of IP address which is resolved by a DNS server to all Avaya Breeze™ nodes in the cluster.
  4. IM clients point to the Leader Avaya Breeze™ node SM100 IP address which redirects the clients to a particular Avaya Breeze™ node based on load-balancing policy.

Answer(s): D

Explanation:

Enable load balancing for a cluster if you want to scale the HTTP services without targeting a particular Avaya Breeze™ server. All the requests are sent to the cluster IP address.
When you enable load balancing, two Avaya Breeze™ servers are chosen as the active and standby load balancing servers. The active load balancer distributes the HTTP requests to all the other servers in the cluster in a round robin fashion.

When Avaya Aura® Presence Services is implemented, which statement is true about Port Management?

  1. It allows multi-media services over a standard Web-Browser.
  2. It allows independent management capabilities to filter out undesired message to every Avaya Aura® Presence Services user.
  3. It collects statistics about Port-Usage from each Presence-compatible endpoint across the network.
  4. Port 5222 is used for one-X® Endpoints, while Port 5269 is open for connecting with other XMPP 3rd-Party Servers.

Answer(s): D

Explanation:

Port 5222: XMPP connection configuration
The Connection Manager runs by default when you install the XCP server. It is configured with a JSM Command Processor and two XMPP directors. The XMPP directors handle communication with IM clients. One of the directors is configured to use port 5222 and the other is configured to use port 5223 for secure communications.
Port 5269: Example Obtaining the Server-to-Server Port from an Openfire server
Procedure
1. Log in to the Openfire Web console.
2. Click Server > Server Settings > Server to Server.
3. In the Service Enabled section, the Enabled check box should be checked, and the port value is contained in the box to the right of Remote servers can exchange packets with this server on port.
By default the value is 5269, and it is recommended that this default value be maintained.

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?

  1. traceSBC
  2. traceSM –m
  3. traceTOOL
  4. trace

Answer(s): 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.

Example:
# traceSBC

In the context of Avaya Aura® Presence Services 7.x, what is a Fetcher?

  1. It is a kind of watcher that requests a one-time view of the user’s current presentity information, but does not get future presentity information for a user.
  2. It is a user whose devices are sending status or presentity information on his behalf using a Publish message regarding his communication status.
  3. It is a watcher that is subscribing to current and future presentity information from another user.
  4. It is the presence information about a user that the system reports.

Answer(s): A

Explanation:

Fetchers pull the value of presence information for a specific presentity from the presence service. If a fetcher is fetching information on a regular basis, it is called a poller. Subscribers, on the other hand, subscribe to presentity information on the presence service.
