For institutions and test centers facing unreliable internet or wanting full control over infrastructure costs and data security, the Addmen Computer-Based Test (CBT) in Labs using Offline Server offers the ideal solution. By deploying the exam software on a locally owned offline server within a LAN setup, you can deliver full CBT test functionality without dependency on cloud‑based connectivity.
Read the Server Configuration details
Low or No Internet Dependency — Since all exam data resides on a lab server, test conduction is unaffected by internet outages or slow connectivity.
Cost Efficiency — Avoid recurring cloud hosting charges; greater control over server costs and maintenance.
Control & Security — Full ownership of infrastructure, greater control over data privacy and security.
Consistency & Reliability — Local network (LAN) based configuration ensures stable test delivery, minimal latency.
Ideal for Remote / Infrastructure Constrained Locations — Labs in regions with intermittent internet benefit greatly from this setup.
Lab Server Deployment
          Install the CBT software on a dedicated server located inside the exam       lab. Ensure server hardware meets recommended specifications. (See server       configuration details.)
LAN Connectivity
          Connect student terminals (computers in the lab) via LAN to the server.       All machines must be on the same Local Area Network (same subnet). Avoid       shared or proxy networks if possible.
IP Address Setup
          Server should provide access via local LAN IP; all terminal computers must       be able to reach the server’s LAN IP without routing via external       internet.
Test Delivery &       Monitoring
          Tests are delivered to terminals over the LAN. Proctoring / monitoring       tools can run locally. Data (responses, logs) stay within the local       network until after exam completion.
Data Consolidation       & Result Generation
          After tests are complete, responses are collected on the server. Result       calculation, reports, analytics all happen locally. Only necessary exports       or backups may be transferred externally.
Full functionality of Computer Based Test (CBT) Software in offline mode
Supports all test types: objective, subjective, mixed.
Real-time test monitoring via terminal dashboards on LAN.
Secure access restrictions, authentication, role‑based user permissions.
Support for multimedia questions where needed (if supported offline).
Robust logging, item‑tracking, audit trails.
Detailed reports, analytics, export options (CSV, Excel, PDF).
Scalability: supports dozens to hundreds of concurrent exam terminals in lab environment.
Reduced Dependency on Internet Infrastructure — Enables tests in areas with poor or no internet.
Improved Uptime & Reliability — Local setup avoids many external points of failure.
Data Privacy & Control — Sensitive exam data remains within institutional premises.
Better Cost Management — Lower hosting/ bandwidth costs, one‑time investment.
Scalable for Multiple Labs — Same model can be replicated across labs with similar setups.
Schools, colleges, universities in regions with unstable internet connectivity
Examination boards or test centers aiming for offline CBT deployments
Remote training or testing institutes needing controlled environments
Government or regulatory bodies with strict data privacy requirements
Organizations wanting to avoid recurring cloud hosting expenses
Q:  Can I run CBT in labs if my internet goes down during the exam?
      A: Yes — since the setup is entirely local (server + LAN), ongoing exams are  unaffected by external internet issues.
  
Q:  How many computers can be supported in a LAN‑based lab setup?
      A: That depends on hardware specs and LAN infrastructure. Proper server  capacity and network switch bandwidth are crucial.
  
Q:  Is data from offline labs secure?
      A: Yes — because data does not traverse public internet during the exam. Local  storage, audit logs, role-based permissions and physical security help ensure  high data security.
  
Q:  Can I later sync results or backups with cloud or external systems?
      A: Yes — once exams conclude, results, logs, and reports can be exported or  synced manually or via secure channels as needed.
  
Q:  What networking configurations are required?
      A: All terminals and server must be on the same LAN; server should have static  local IP; avoid shared or proxy LAN; ensure low latency connections; stable  router/switch.
