In combination with an Avaya SIP Telephone, which option below supports shuffling where no DSPs are utilized during an active call (peer-to-peer RTP)?
A. 96xx SIP and 2400 Series Digital phone
B. 46xx SIP and Analog phone
C. 96xx SIP and 46xx H.323 phone

Which two design issues relate to increasing security in VoIP converged solutions? (Choose two.)
A. suggesting upgrading LAN switches to support QoS
B. defining VLANs to limit access from specific IP endpoints
C. considering encryption on IP calls for protection from eavesdropping
D. considering G.729 compression to protect IP calls from eavesdropping
Your client is considering a VoIP application for their S8500 Media Server and G650 Media Gateway. Due to the time-sensitive nature of VoIP applications, several issues should be discussed prior to arriving at a final design. Which two VoIP guidelines should you discuss with the customer? (Choose two.)
A. VoIP should be implemented on an entirely switched network.
B. VoIP will cause some discourse due to lower voice quality than TDM calls.
C. VoIP endpoints should be placed on separate subnets or VLANs based on communities of interest.
D. When PCs are attached to IP phones, the uplink to the Ethernet switch should be at least 20 Mbps.
What is the preferred method for downloading firmware files to IP phones?
A. TFTP is the preferred method, because it is better suited for large IP telephone deployments.
B. HTTPS is the preferred method because firmware file downloads are encrypted using Transport Layer Security (TLS).
C. TFTPS is the preferred method because firmware file downloads can be encrypted using Transport Layer Security (TLS).
D. There is no preferred method. Any of these addresses can be included in Option 176 within the DHCP scope.
An RFP for a Interactive Voice Response (IVR) unit and mid-sized communication system has been released. You are responsible for determining the design solution. The RFP states that the IVR platform must be engineered to handle 135 25-second messages during the busy hour. You calculate this requirement to equal 47 ports. If you provide 47 ISDN PRI trunks (two ISDN PRI facilities), which two traffic concerns must you consider? (Choose two.)
A. No trunk growth is available on the ISDN PRI facilities.
B. 47 active trunks overload the two ISDN PRI facilities, seriously affecting traffic load and call completions.
C. Considering there is only one channel for signaling, a backup D channel cannot be provided, affecting traffic if the D channel fails.
D. ISDN PRI facilities direct from the central office limit the caller's ability to connect to the proper resource, causing increased usage.
A customer has two buildings in a campus LAN environment. The current number of employees is 200 and they are adding another building with 100 employees next year. Each employee is expected to have one IP phone. What is the appropriate IP addressing scheme for the IP phones with the anticipated growth?
A. 10.1.1.254/21
B. 172.16.1.0/23
C. 192.168.1.0/24
D. 192.168.1.3/24
What are two reasons for choosing 802.11a hardware for WLAN installs, instead of 802.11b/g? (Choose two.)
A. 802.11a hardware operates at 2.4GHz.
B. 802.11a hardware has greater range than 802.11b/g.
C. 802.11a has a greater number of non-overlapping channels.
D. 802.11a hardware is not disrupted by RF interference from microwave ovens.
You have a corporate site with an S87xx Media Server in location A, and a remote site with an G700/ S8300 LSP processor in Location B. The WAN connection goes down. In what sequence will the G700 register with the S8300?
A. Each H.248 gateway will reboot and register with the S8300 LSP when it comes back up.
B. The S8300 LSP processor reboots, and then notifies each H.248 gateway it is now the primary call processor.
C. The S8300 LSP processor notifies each H.248 gateway in the media controller list that it is now the primary call processor.
D. Each H.248 gateway will detect that the S87xx Media Server is not available and will reregister with the next Media Server in the media controller list.
Your client has an existing S8500 Media Server with G700 Media Gateways running Communication Manager (CM) R1. Your client wants interoperability with Session Initiated Protocol (SIP) endpoints. What do you tell your client?
A. SIP interoperability is being considered, a firm interoperability date is not available at this point.
B. The SIP protocol is still evolving. When it is finalized, Avaya will make interoperability available.
C. The introduction of SIP interoperability became available with CM Release 2. An upgrade will be required.
D. With their existing system, SIP interoperability is supported via third-party SIP/ H.323 conversion servers.
Several Avaya G700 Media Gateways controlled by an Avaya S8300 Media Server have been proposed to a multi-location customer. The customer has an existing WAN and has expressed concern about backup if the primary S8300 Media Server fails. Which is the best option to provide increased survivability?
A. a separate WAN link to each site
B. a dedicated survivable G350 LSP
C. an LSP implemented on a remote location G700
D. an LSP at the main location on the same G700 where the S8300 resides
