78202T Sample Questions & Answers
System configuration with the Manager application ties with status-application troubleshooting for the biggest share, ahead of platform editions tied with centralized voicemail across a small community network, and setting up Voicemail Pro.

Troubleshooting and Diagnostics · SIP Trunk Configuration
A support technician is troubleshooting a new SIP trunk where inbound calls are intermittently rejected by the provider with a '403 Forbidden' or '401 Unauthorized' response. The issue seems to occur more frequently after network changes. The IP Office is behind a NAT firewall. Which TWO of the following settings are most critical to verify and correct in the SIP Line configuration to resolve this type of authentication failure? (Select TWO).
Show answer & explanation
Correct answers: A, C
Many SIP providers use the domain name in the SIP headers for authentication and routing. If the 'ITSP Domain Name' is incorrect, the provider's SBC may reject the registration or call setup requests, resulting in a '403 Forbidden' or '401 Unauthorized' error.
When the IP Office is behind a NAT, it will place its private IP address in the SIP headers. Providers often validate the source IP against the registered public IP. Setting 'Use Network Topology Info' correctly ensures the public IP is inserted into the SIP Contact and Via headers, which is essential for the provider to route responses back and authenticate the session, preventing 403/401 errors.

Troubleshooting and Diagnostics · SCN Networking Requirements
A technician is troubleshooting a newly deployed Small Community Network (SCN) between a primary Server Edition in New York and an IP500 V2 in London. Internal extension-to-extension calls work, but users report intermittent choppy audio and occasional dropped calls. RTCP monitoring in SSA shows high jitter values specifically for calls traversing the SCN. The WAN link is a 100Mbps MPLS circuit with ample bandwidth. Which of the following is the most likely cause of the poor voice quality?
Show answer & explanation
Correct answer: C
High jitter on a link with sufficient bandwidth is a classic symptom of a Quality of Service (QoS) problem. The IP Office marks VoIP packets with DSCP values (typically EF for Expedited Forwarding) to signal that they should be prioritized. If the network devices (like the MPLS routers) are not configured to trust and act on these markings, the real-time voice packets get queued with non-prioritized data traffic, causing variable delays (jitter). A codec mismatch or different software versions would typically cause calls to fail entirely or have consistent issues, not intermittent quality problems. Silence suppression affects bandwidth usage, not directly causing high jitter.

Small Community Networking (SCN) · Centralized Voicemail
In a Small Community Network with a central Voicemail Pro server at the main office, users at a remote branch report that when they delete a voicemail message from their phone, the Message Waiting Indicator (MWI) light does not turn off. They can retrieve and listen to messages without issue. What is the most likely configuration error causing this specific problem?
Show answer & explanation
Correct answer: C
For MWI updates to function correctly with centralized voicemail, the central Voicemail Pro server needs to send control messages back to the IP Office at the remote site. This requires the central IP Office system to have a defined IP Route that directs traffic destined for the remote site's LAN (where the branch IP Office resides) across the SCN. Without this return route, the MWI 'off' signal from the voicemail server never reaches the branch system to extinguish the light. Since users can retrieve messages, the route from the branch to the central site is working correctly; the issue is with the return path.

IP Office Platform Architecture and Components · Server Edition
True or False: In an Avaya IP Office Server Edition deployment running on VMware, allocating more vCPUs to the virtual machine will always improve its ability to handle high call volumes.
Show answer & explanation
Correct answer: B
This statement is false. While adequate CPU resources are necessary, over-allocating vCPUs beyond the actual need can degrade performance for real-time applications like VoIP. On a busy VMware host, a VM with many vCPUs may have to wait longer for the hypervisor to schedule all its vCPUs to run simultaneously on physical cores. This can lead to increased CPU Ready time (co-stop), which negatively impacts voice quality. It is Avaya best practice to allocate only the number of vCPUs specified in the deployment guides for the required capacity.

Voicemail Pro Configuration and Maintenance · Auto Attendant Configuration
An administrator is designing a Voicemail Pro call flow for a corporate directory. The goal is to allow external callers to find an employee by spelling the first three letters of their last name on their phone's keypad. Which THREE Voicemail Pro actions are essential to build this specific functionality? (Select THREE).
Show answer & explanation
Correct answers: A, C, F
A Menu action is needed to prompt the caller and collect the DTMF digits (the first three letters of the name).
A Transfer action is required to connect the caller to the extension of the user that is found by the directory search.
The Directory action is the core component that takes the collected DTMF digits, searches the IP Office user directory for matching names, and plays back the results to the caller.
