2.A company has a Succession 1000/1000M Rls. 3.0 system (Main Office). They have just completed installing Branch Office hardware for a small remote site. The Internet Telephones have been programmed within Overlay LD 11 at the Main and Branch Office. They have tried several times to install the Internet Telephones, but have been unsuccessful. Each attempt has resulted in the Internet Telephones registering in local mode. Which three steps should you perform to help you resolve this issue? (Choose three.)

A:Check that the BUID prompt can be routed by the Gatekeeper.
B:Check that the Main Office H.323 endpoint is registered to the Gatekeeper.
C:Check that the Branch Office H.3.23 endpoint is registered to the Gatekeeper.

1.Given the following VoIP system information, evaluate the company’s VoIP implementation for potential issues or non-compliance to emergency-service requirements:
A company has installed a VoIP system that is able to identify the location of a caller based on the telephone that the caller uses to place a call.
The company is moving to a new office and all employees are asked to move their own Internet Telephones to their new desks in the new office.
The administrator of the VoIP telephone system moves the VoIP gateway device from the old office to the new office on moving day without making any changes to database for user location identification.
Upon completion of the VoIP gateway move, the administrator is out of the office due to a family emergency for three days. During that time a few employees have engineered their Internet Telephones to make calls from their home offices using the company VoIP gateway/switch.
What are the two liability assessments for this configuration? (Choose two.)
A:A Public Service Answering Point (PSAP) NOT located in the same jurisdiction as the caller could answer all call types, but this is NOT standard operating procedure.
B:All E911/E211 calls could encounter connection issues, but this could be corrected once the VoIP administrator updates the user database.
C:A PSAP NOT located in the same jurisdiction as the caller could answer emergency calls, but these calls would receive NO delay in response to the emergency.
D:All call types could be completed successfully and in the most expedient manner, but there could be issues with the location and identification of E911/E211 callers.
E:All call types would NOT indicate the number the calls originated from because the Automatic Number Information (ANI) would NOT be available. This information would only be available on Internet Telephones that are able to identify caller locations via E911/E211.
Correct Answers:  A, B
2.Given the following network information:
A company with a mixed VoIP and data network is experiencing bad voice quality with VoIP calls during normal business hours.
Tests within their  LAN segments warn of excessive jitter, delay, and in some cases packet retransmissions.
There is a pair of switches that all traffic converges upon. The link between the two switches is a 100/Full Fast Ethernet connection that is operating at near maximum capacity for the majority of the day.
At any given time, the estimated traffic on the link between the two switches is 200 Mbps.
Which two configuration changes will improve the voice quality of the VoIP calls and prevent possible VoIP issues in the future between these two switches? (Choose two.)
A:Place a router between the two switches and configure the 100 Mbps links to the two switches with a higher QoS for VoIP traffic.
B:Prioritize the traffic on the switches to give VoIP improved QoS. Prioritize only the traffic on the switches to give VoIP calls improved QoS.
C:Provide a larger aggregated bandwidth of 300 Mbps by trunking three interfaces together on the two switches using Multilink Trunks (MLTs).
D:Purchase two new Layer 2 switches that are capable of gigabit Ethernet to replace the Fast Ethernet connection with a single gigabit Ethernet connection.
Correct Answers:  B, C
3.Which component provides remote VoIP network management capability?
A: Reach Line Card Manager
B: Nested Tunneling Manager
C: Virtual Private Network Manager
D: Optivity Telephony Manager (OTM)

Correct Answers:  D

1.A Contivity configuration has two private interfaces (LAN 0 and LAN 1) and one public interface (LAN 3) with Application servers residing on LAN 0. An administrator needs to create a default rule in order to allow users from LAN 1 and tunneled users from LAN 3 to access the application servers in LAN 0. What would be the most secure interface classification for the source interface?

A: Any
B: Trusted
C: Tunnel: Any
D: LAN 1 and LAN 3
Correct Answers:  B

2.A Contivity has two private interfaces (LAN and DMZ) and one public interfaces (INT). Workstation1 with an IP address of 10.10.10.1/24 is in the network that is directly attached to the private interface LAN. Workstation2 with an IP address of 20.20.20.1/24 is in the network that is directly attached to private interface DMZ. The requirement is to block only traffic from workstation1 to workstation2 using interface filters to be applied to the private interface DMZ. Select the most appropriate filter action, direction, and address for the access control filter.

A: Filter action = Deny ; Direction = Inbound ; Address = 20.20.20.1
B: Filter action = Deny ; Direction = Inbound ; Address = 10.10.10.1
C: Filter action = Deny ; Direction = Outbound ; Address = 10.10.10.1
D: Filter action = Deny ; Direction = Outbound ; Address = 20.20.20.1

1.Which statements apply to an Alteon SSL Accelerator running in non-transparent proxy mode?(Choose two.)

A:requires non transparent to use any load balancing switch
B:decrypts encrypted traffic and uses the ASA’s own IP address when initiating sessions sent to backend real servers
C:decrypts encrypted traffic and maintains the original client IP address when initiating sessions to backend real servers
D:cannot be implemented without the use of RTS enabled on Alteon load balancing switches to provide successful backend packet redirection
Correct Answers:  A, B

2.An Alteon customer has the following network scenario:

 20 virtual Servers in a server farm providing RTSP & HTTP services via 2 ISP links
 Each of the ISP’s routers are setup to pass traffic to both the Alteon switches at the same time.
 Each virtual server is taking an equal share of the bandwidth.
 Alteon switches to provide redundancy.

Which configuration provides optimal performance?

A: RTSP and HTTP will not work through the same switch since RTSP uses UDP.
B: Use VRRP Active-Active with sharing enabled, all the switches providing services to all the virtual servers.
C: Setup one Alteon switch to provide RTSP services and the other Alteon switch to provide HTTP services, since mixing RTSP and HTTP traffic is not advisable.
D: Setup VRRP Active-Standby with each service switch acting as VRRP Master for 10 virtual servers and acting as VRRP backup for the other 10 serves. Same with other Alteon switch.
Correct Answers:  D

1.Given the following network information:
An administrator of a small VoIP network is using H.323 as a messaging protocol.
The network equipment supports H.323 version 2.
Over time, the administrator observes latency on call-establishment between terminal devices.
Over time, an end-users reports that that poor voice quality has increased.
A sniffer is placed on the network to monitor traffic between terminals and gatekeepers at various sites.
Sniffer results indicate that latency and voice quality issues are due to scaling issues with H.323 and its usage of messaging on call setup.
What is the quickest and the most cost effective action the administrator can take to help ease these issues?
A: Implement ast Start?H.323. Implement ?ast Start?H.323.
B: Split up the terminals between LANs.
C: Add additional VoIP gateways to the network.
D: Migrate the network to Session Initiation Protocol (SIP).
Correct Answers:  A
2.A customer’s network is using a Meridian Customer Defined Network (MCDN).  The network consists of three nodes. By design, when node A calls node B and the call is re-routed to node C, a direct connection is established between node A and node C. Which protocol ensures that calls are handled this way?
A: Automatic Trunk Utilization
B: Trunk Anti-Tromboning (TAT)
C: Trunk Route Optimization (TRO)
D: Basic Automatic Route Selection (BARS)

Correct Answers:  C
