Avaya 31860X : Avaya IX™ Calling Design Exam

A customer wants to prevent additional calls from being established, and to preserve the quality active calls when the capacity limit on the WAN link is reached. The branch inter-office communication use rate is one trunk for every 20 users over the customer's star topology WAN. 600k of the WAN bandwidth is dedicated to voice.
Assuming G.729 (30k bandwidth per call) is used, which Call Admission Control (CAC) limit will meet the customer s requirement?

• A. Set the CAC limit to 20 inter-branch calls for each branch location.
• B. Set the CAC limit to 10 incoming calls and 10 outgoing inter-branch calls at each branch.
• C. Set the CAC limit to 200 intra-branch calls globally in the WAN network.
• D. Set the CAC limit to 2 Mbps just for voice traffic at the headquarters main office WAN connection.

You are helping a new Sales Engineer learn about Avaya Aura survivability. If a branch that has only SIP devices and has deployed a Survivable Remote Communication Manager and Session Manager, the engineer wants to know what happens when the connection to the Avaya Aura core is down.
What are two things you would tell the engineer? (Choose two.)

• A. The Core Communication Manager provides feature functionality.
• B. The Survivable Remote Communication Manager provides feature functionality.
• C. SIP telephones fail-over to the Survivable Remote Session Manager.
• D. The local SIP device cache provides feature functionality.

A customer is interested in deploying geo-redundant System Managers. Which two requirements would they need to know? (Choose two.)

• A. Both servers must have the same IP address.
• B. The two servers can reach each other on the network.
• C. Both servers must be on the same IP subnet.
• D. The two servers must have the same version of software,

You are designing media gateways at remote locations for a customer. They have requested the following:
* Analog telephone calls go through the PSTN in case of power outage.
* Redundant power supply
* The same administrative and telephone functionality during WAN outage Which design meets these customer requests?

• A. A design with G430 gateways with dual power supply, and S8300 Survivable-Remote
• B. A design with G450 gateways with dual power supplies, and Standard Local Survivability A design with G430 gateways with dual power supplies, and Standard Local Survivability
• C. A design with G450 gateways with dual power supplies, and S8300 Survivable-Remote

A customer has asked you to provide a design for a 1,400 H.323 stations and eight T-is. You have provided the following design:
* Communication Manager Simplex
* Two G450 Media Gateways
* Eight T1Media Modules
* 1,400 - 9611G IP Phones
* 1,400 - Core Licenses
The customer responds that the following changes need to be made to the design:
* Change all the H.323 stations to SIP stations.
* Add 2 additional T1s to the design as the customer has higher traffic than initially thought.
* All users will need to be able to use the Skype for Business client for telephony.
Which two changes need to be made to the design to comply with the customer's revised requirements?
(Choose two.)

• A. Add two T1Media modules and distribute the T1modules evenly between the two G450 Media Gateways.
• B. Add an additional 1,400 Cote licenses to the design to support Lync integration.
• C. Add 1,400 SM SIP connection licenses.
• D. Add System and Session Manager Servers to the design.
