Large Scale Online Exam – Distributed CBT Architecture

Conducting large-scale computer-based tests (CBTs) like CAT or IBPS across multiple centers requires more than a single server setup. Addmen’s distributed architecture utilizes multiple servers and licenses to manage high user loads, ensure redundancy, and facilitate centralized result processing.

Key Features of Addmen’s Large Scale Online Exam System

• Distributed Server Architecture:
  Deploy multiple servers across various locations to distribute the workload and reduce dependency on a single point of failure.

• Modular Licensing:
  Use multiple software licenses to scale the system according to the number of exam centers and candidates.

• Centralized Result Processing:
  After the exam, collate data from all servers to process results centrally, ensuring consistency and efficiency.

• High Availability & Redundancy:
  Implement backup servers and failover mechanisms to maintain system uptime during the exam period.

• Scalable Infrastructure:
  Easily scale the system by adding more servers or licenses to accommodate increasing numbers of candidates.

Requirements for Implementation

1. Understanding the System:
   Ensure all stakeholders comprehend the technical components and deployment requirements.

2. Single Point of Contact:
   Designate a primary contact person to streamline communication and decision-making.

3. Active Participation:
   Involve all relevant team members from the beginning to avoid confusion and ensure smooth implementation.

4. Acknowledgment of Information:
   Confirm understanding of shared information at each step to maintain alignment.

5. Pre-Demo Communication:
   Engage in direct communication with the client before any demonstrations to address specific needs.
