Free 920-443 Sample Questions:

1. Given the following information:
• A company has Succession 1000/1000M Rls. 3.0 systems at two locations providing IP-PBX services.
• The headquarters and manufacturing plant Succession systems are networked via their managed IP backbone.
• In the event of an IP network failure at either site, communication must be maintained and the best alternative route is the Public Switched Telephone Network (PSTN).
• Normally, users at the headquarters dial an access code, the location code of 456, and then a four-digit extension number to reach the plant users.
• To reach plant users using the PSTN requires the users at the headquarters to dial the access code, area code (817) plus NXX (789), and then the four-digit extension number to reach the plant users.
To make the call seamless to users, some digit manipulation must occur. How should you program the Digit Manipulation Index (DMI) for the fallback PSTN route?
A. Set DEL to 3 and INS to NS 817789.
B. Set DEL to 3 and INS to NS 6 817789.
C. Set DEL to 456 and INS to 6.
D. Set DEL to 456 and INS to 817789.
Answer: A

2. Given the following information:
• A company has a multi-site Succession 1000/1000M Rls. 3.0 system providing IP-PBX services.
• They use IP Peer Networking in conjunction with Network Alternate Route Selection (NARS) to communicate among their sites.
• They have their Succession systems configured for fallback to the Public Switched Telephone Network (PSTN) in case of a data network failure.
• A review of the system call detail report reveals that calls to the San Francisco site are always routed over the PSTN.
• A simple ping test on the IP network verified that all Succession equipment is connected.
Which two tasks should you perform next to isolate this fault? (Choose two.)
A. Verify that San Francisco is defined and registered using Gatekeeper Element Management (EM).
B. Verify that the virtual route has been defined in the Route Data Block (RDB) of the Call Server using EM.
C. Verify that the first route choice in the Route List Block (RLB) is the virtual route of the Call Server in Overlay LD 86 or using EM.
D. Verify that San Francisco's IP Address is correct in the Embedded LAN (ELAN) database of the Call Server in Overlay LD 117 using OTM.
Answer: AC

3. A company has a two-site Succession 1000/1000M Rls. 3.0 system (sites A and B) providing IP-PBX services. Both Succession systems are networked via a managed IP backbone. One system is a Succession Main Office (MO) and the other is a Succession Branch Office (BO). To configure the networked Succession systems to enable the following:

Answer: C

4. A company plans to have a Succession 1000/1000M Rls. 3.0 Main Office (MO) site with one Branch Office (BO) site. The BO and MO will be connected via virtual trunks. Users at both sites will use Coordinated Dialing Plans (CDPs) to dial between the sites. They want long distance and CDP calls originating from the BO to route to the MO. All long distance calls will be tagged as international calls originating from the BO. They have NO plans to expand the BO in the future. What is the most efficient way of routing calls from the BO?
A. In the Gatekeeper, select the BO as the tandem endpoint for the MO.
B. In the Gatekeeper, select the MO as the tandem endpoint for the MO.
C. In the Gatekeeper, all Numbering Plan Areas (NPAs), international numbers, and CDP steering codes should be defined under the MO.
D. In the Gatekeeper, select the MO as the default route for CDP and international calls. All NPA ranges will need to be defined under the MO.
Answer: D

Answer: AD

15. Given the following information:
• A company with a Succession 1000/1000M Rls. 3.0 system has IP users located at their main campus. They plan to add IP users at a remote campus. These IP users will be given Internet Telephones (i2xxxs) that will register with the Succession system at the main campus.
• A major concern for the company is the limited bandwidth between the main campus and the remote campus.
• The existing bandwidth is currently shared between voice and data traffic. Thus, they need to control the amount of bandwidth used for IP calls between the main and remote IP users.
• They are NOT concerned about bandwidth usage between IP users at main campus or bandwidth usage when remote IP users call each other.
What is the best method for controlling bandwidth usage between the main and remote IP users?
A. Configure both the main and the remote IP users to be in the same zone and have the zone setup for Best Bandwidth (BB) for interzone and intrazone calls
B. Configure the main IP users to be in zone 1 and the remote IP users to be in zone 2. Have zone 1 setup for BB for intrazone calls to allow them to conserve bandwidth usage between the main and remote IP users.
C. Configure the main IP users to be in zone 1 and the remote IP users to be in zone 2. Configure zones 1 and 2 for BB for interzone and intrazone calls.
D. Configure the main IP users to be in zone 1 and the remote IP users to be in zone 2. Configure zones 1 and 2 for BQ (Best Quality) for intrazone calls and BB for interzone calls.
