Which file is essential for converting the generic CMS installation into a customer-specific licensed system with the correct number of agent and supervisor seats?
Show answer details
Correct answer: A
CMS requires a license file to unlock capabilities. This is typically managed via a WebLM server (centralized licensing) or a local license file installation. The license determines the maximum concurrent supervisors, agents, and specific features (like HA or ODBC access).
- 2
A CMS administrator attempts to create a new user but receives an error that the maximum number of users has been reached. Where can the administrator check the system's licensed limits?
Show answer details
Correct answer: D
The License Information screen in the System Setup menu (or via
cmsadm) displays the currently installed license limits, including the maximum number of defined users and concurrent supervisor sessions. - 3
When performing a CMS upgrade from R19 to R21, what is the critical first step regarding data preservation?
Show answer details
Correct answer: A
Before any upgrade activity, a full system backup (Maintenance Backup) must be successfully completed and verified on an external storage device (NFS). If the upgrade fails or requires a fresh install of the new OS/App, this backup is the only way to restore the historical data and configuration.
- 4
Which port must be open on the firewall to allow the CMS Supervisor PC client to connect to the CMS Server for standard reporting sessions?
Show answer details
Correct answer: D
Modern CMS Supervisor clients (and the terminal emulator) connect via SSH (Port 22) for secure communication. Legacy versions used Telnet (Port 23), but R21 and modern security standards mandate SSH. While there are other ports for specific features (like 5000/5001 for some data streams), Port 22 is the primary session initiation port.

Scenario: A customer reports that new agents added to Communication Manager are not appearing in CMS Dictionary or Reports. What manual step is required in CMS if 'Dictionary Synchronization' is not automated?
Show answer details
Correct answer: C
CMS does not automatically discover agent names from CM unless a synchronization tool is configured. The numeric ID might collect data, but for it to appear with a name in reports (and often to be trackable if strict checking is on), the administrator must define the Agent Login ID and associated Name in the CMS Dictionary subsystem.

A solutions architect is designing a high-availability Avaya Call Management System (CMS) R21 solution for a global contact center. The customer requires that the CMS implementation supports 2,000 concurrent supervisor sessions and processes data from 10 separate Communication Manager clusters. Which deployment model and hardware profile must the architect specify in the OVA deployment to meet these specific scalability requirements?
Show answer details
Correct answer: A
For large-scale deployments supporting 2,000 concurrent sessions and multiple ACD connections, the Enterprise Profile in the OVA deployment is required. This profile allocates sufficient vCPU (typically 8-16 cores) and RAM (32GB+) to handle the heavy JDBC and reporting load. Smaller profiles (Small/Medium) have hard limits on concurrent sessions and ACD connections that would not meet the requirement.
- 7
Which of the following components is responsible for the physical data transmission between the Avaya Aura Communication Manager and the CMS server, and which protocol is primarily used for this data stream?
Show answer details
Correct answer: D
The data link between Communication Manager and CMS is established via TCP/IP. On the CM side, this is handled by the Processor Ethernet (PE) interface or a legacy C-LAN circuit pack. This connection transmits real-time event data which CMS buffers and processes into historical intervals.
- 8
During the planning phase for a CMS R21 installation on VMware, an engineer must calculate storage requirements. The customer requires 5 years of daily data retention and 2 years of interval data retention for 5,000 agents. Which factor has the HIGHEST impact on the disk space sizing calculation?
Show answer details
Correct answer: A
Interval data (typically 15 or 30 minutes) consumes significantly more storage than daily, weekly, or monthly summaries because it generates 48-96 records per agent/skill per day. Extending interval retention from the default (often 31-62 days) to 2 years requires massive disk space allocation compared to daily summaries.
- 9
A technician is preparing to deploy the CMS R21 OVA template. Which TWO network interfaces are typically configured during the initial deployment script to separate management traffic from ACD data traffic? (Select TWO)
Show answer details
Correct answer: A, B
See explanation above.
Standard best practice for secure CMS deployments involves using eth0 for management traffic (SSH, Supervisor clients, Web access) and a secondary interface (often eth1) dedicated to the switch link (ACD traffic) to prevent client reporting loads from impacting data collection latency.
- 10
True or False: In an Avaya CMS R21 deployment on AXP Private Cloud, the underlying operating system management (patching, kernel updates) is entirely the responsibility of the customer, identical to a bare-metal installation.
Show answer details
Correct answer: B
In AXP Private Cloud or when using the provided OVA appliance model, the OS is delivered as a 'black box' or appliance. While the customer initiates updates, the packages are strictly controlled and provided by Avaya via service packs (RPMS). The customer does not perform standard RHEL repository updates (
yum updatefrom public repos) as this would break the supported configuration.
