72201T Sample Questions & Answers
Troubleshooting and diagnostics carries the biggest share, just ahead of three evenly tied areas, core component architecture, SIP and H.323 protocol interoperability, and remote-worker network support, with the smallest portion on administration and maintenance.

- Question 1Beginner
Avaya Aura Core Components Architecture · Avaya Aura Session Manager
True or False: In an Avaya Aura deployment, the Session Manager's Personal Profile Manager (PPM) service is responsible for providing SIP endpoints with their contact lists and button configurations.
Show answer & explanation
Correct answer: A
True. PPM (Personal Profile Manager) is a web service running on Session Manager. SIP endpoints (like J100 series or Avaya Workplace) communicate with PPM via HTTP/HTTPS after SIP registration to download contact lists, button mapping, and other feature data that SIP signaling alone does not carry.

Avaya Aura Core Components Architecture · Avaya Aura Device Services
A customer is deploying Avaya Aura Device Services (AADS) to support dynamic configuration for Avaya Workplace clients. Users report they cannot log in using their email addresses. The administrator verifies that the DNS SRV records are correct.
Which service on the AADS server must be running and accessible to process the initial auto-configuration request?
Show answer & explanation
Correct answer: B
AADS provides the Web Deployment Service to handle the initial configuration and settings for Avaya Workplace clients. When a user enters their email, the client performs a DNS lookup to find the AADS server and then connects to the Web Deployment Service to retrieve connection settings.

Avaya Aura Core Components Architecture · Avaya Aura System Manager
Case Study: GlobalTech Inc.
GlobalTech has a distributed Avaya Aura network with a main data center in New York and a disaster recovery site in London.
- New York hosts System Manager (SMGR) and primary Session Manager (SM1).
- London hosts secondary Session Manager (SM2).
- All SIP endpoints are configured to register to SM1 primarily and SM2 secondarily.
Scenario: The WAN link between New York and London fails.
- Users in London can still call each other.
- Users in London cannot make changes to their 'Call Forwarding' settings using the self-administration portal.
- The System Manager dashboard shows SM2 as 'unreachable'.
What is the primary reason the London users cannot change their settings, despite their phones being operational?
Show answer & explanation
Correct answer: C
While Session Managers contain a replicated copy of the database to process calls during a WAN outage (Survivability), the actual administration and modification of user profiles (like Call Forwarding settings via portal) require write access to the System Manager database. If the WAN is down, the London components cannot reach the SMGR in New York to commit these changes.
- Question 4Intermediate
Protocol Interoperability and Call Processing · Codec Management and Compatibility
When troubleshooting a SIP interoperability issue between Avaya Aura Session Manager and a third-party PBX, the engineer collects a trace using 'traceSM'. The trace shows the call failing with a '488 Not Acceptable Here' response.
Which component is most likely responsible for generating this specific error code in this context?
Show answer & explanation
Correct answer: A
A SIP '488 Not Acceptable Here' response typically indicates a media negotiation failure. It means the destination (or a gateway/SBC in the path) received the offer but cannot support any of the proposed codecs or media parameters in the SDP (Session Description Protocol).
- Question 5Beginner
Administration and Maintenance · System Administration Tasks
An administrator needs to perform a backup of the Avaya Aura Session Manager (SM) data.
What is the correct method to back up the Session Manager configuration and where is this initiated?
Show answer & explanation
Correct answer: B
In the Avaya Aura architecture, Session Manager does not have a local database that is backed up independently for configuration. All SM configuration data (users, routing, domains) resides in the System Manager database. Therefore, performing a System Manager backup secures the Session Manager configuration.
- Question 6Advanced
Network Architecture and Remote Worker Support · Remote Worker Architecture
A Remote Worker using an Avaya Workplace client connects via the Session Border Controller for Enterprise (SBCE). The user reports that they can make calls, but after 15 minutes the call always disconnects.
Which SBCE configuration setting is most likely misconfigured, causing the firewall to close the port due to inactivity?
Show answer & explanation
Correct answer: C
Firewalls often close UDP ports if no traffic is seen for a certain period. If silence suppression (VAD) is used or if the Media Inactivity Timer on the SBCE is set too low or incorrectly relative to the firewall's timeout, the session may be terminated. However, a strict 15-minute disconnect often points to a Session Refresh/Session Timer (SIP Re-INVITE/UPDATE) failure or a Media Inactivity Timer cleaning up 'stale' sessions.
- Question 7Beginner
Troubleshooting and Diagnostics · Trace Analysis and Log Review
Which of the following CLI commands is used on Avaya Aura Session Manager to view real-time SIP message traffic, including detailed header information?
Show answer & explanation
Correct answer: C
'traceSM' is the primary command-line tool on the Session Manager server (accessed via SSH) to capture and analyze SIP traffic in real-time. 'list trace' is a Communication Manager command.
- Question 8Intermediate
Avaya Aura Core Components Architecture · Avaya Aura Communication Manager
In an Avaya Aura environment utilizing Communication Manager (CM) and Session Manager (SM), what is the function of the 'Processor Ethernet' (Procr) IP interface on the CM?
Show answer & explanation
Correct answer: D
The Processor Ethernet (Procr) interface is the virtual interface on the Communication Manager server that handles signaling traffic, including SIP signaling trunks to Session Manager and H.248 control links to Media Gateways.
- Question 9Intermediate
Administration and Maintenance · System Administration Tasks
A technician is replacing the default identity certificates on Avaya Aura System Manager.
Which file format is required when importing the new CA (Certificate Authority) root certificate into the trust store?
Show answer & explanation
Correct answer: D
System Manager typically requires certificates to be in PEM (Base64 encoded) format for import into the trust store. While PKCS#12 is used for identity certificates containing private keys, the public CA root is usually imported as PEM.
- Question 10Intermediate
Protocol Interoperability and Call Processing · SIP Signaling and Call Processing
In a scenario where Session Manager is routing a call to Communication Manager, which SIP header does Session Manager primarily use to determine the target Communication Manager instance?
Show answer & explanation
Correct answer: C
Session Manager uses the Request-URI (R-URI) to match Dial Patterns or to route to registered endpoints. While the 'Route' header allows for loose routing in proxy chains, the initial decision of 'where does this number live' is based on analyzing the R-URI against the routing database.
