CBT Technology Infrastructure and Innovations Flashcards

What is a 'lockdown browser' used for in CBT environments?

Answer: To prevent candidates from accessing unauthorized websites or applications during a remotely proctored exam

A lockdown browser restricts the test-taker's computer to the exam interface, blocking access to browsers, applications, and external sites to maintain security.

Which network configuration is critical for ensuring reliable CBT delivery at a US testing center?

Answer: Redundant high-speed internet connections with automatic failover

Redundant internet with failover ensures uninterrupted exam delivery even if a primary connection fails during a live testing session.

What does 'content encryption' mean in the context of CBT item delivery?

Answer: Exam questions are encoded so they cannot be intercepted or read if the data stream is captured

Encrypting content during transmission (e.g., via TLS/SSL) protects question integrity by making intercepted data unreadable to unauthorized parties.

What is the primary role of a 'test delivery system' (TDS) in a CBT platform?

Answer: To manage the secure presentation of questions to candidates and capture their responses

The TDS is the runtime engine that authenticates candidates, serves items, tracks responses, enforces time limits, and submits exam data.

Which technology enables a candidate to take a proctored CBT exam from home in the US?

Answer: Remote online proctoring (ROP) using webcam, microphone, and AI monitoring software

Remote online proctoring uses webcam feeds, AI behavioral analysis, and human proctors to supervise candidates in their own environment.

What is a 'thin client' workstation as used in some CBT testing centers?

Answer: A low-cost terminal that streams the exam interface from a central server with no local processing or storage

Thin clients have no local storage or significant processing power; all exam logic runs on a secure server, reducing the risk of data theft from the endpoint.
