CBT Platform Administration 3 — Questions and Answers
Question 1: An organization is deploying a CBT platform across 50 remote testing sites. Which network requirement is most critical for synchronized exam delivery?
- Minimum 1 Gbps symmetric fiber at each site
- Consistent low-latency internet with sufficient bandwidth for concurrent sessions (Correct answer)
- Dedicated MPLS circuit between all sites and headquarters
- Satellite-only backup connectivity
Correct answer: Consistent low-latency internet with sufficient bandwidth for concurrent sessions
Reliable, low-latency internet with enough bandwidth to support simultaneous test sessions is the core network requirement for remote CBT delivery.
Question 2: A test administrator notices that a candidate's exam timer continued counting down during a documented connectivity outage. What platform feature should have prevented score invalidation in this scenario?
- Auto-submit on timeout
- Offline exam caching with timer pause on disconnect (Correct answer)
- Manual proctor override of timer
- Extended test window for all candidates
Correct answer: Offline exam caching with timer pause on disconnect
CBT platforms that support offline caching can pause or suspend the timer during verified connectivity outages and sync responses when reconnected.
Question 3: Which role-based access control principle should govern who can view live candidate exam responses during an active administration?
- All administrative staff should have full access for support purposes
- Only proctors and compliance officers with a legitimate need should have access (Correct answer)
- Access should be unrestricted to facilitate quick troubleshooting
- Only the exam developer role should have access
Correct answer: Only proctors and compliance officers with a legitimate need should have access
The principle of least privilege restricts access to live response data to roles with a documented, legitimate need such as proctoring or compliance.
Question 4: An administrator is setting up item pools for a Computer Adaptive Test (CAT). Which platform configuration determines how item difficulty is selected for each candidate?
- Randomization seed value
- Item Response Theory (IRT) algorithm parameters and exposure control rules (Correct answer)
- Maximum test length setting
- Time-per-item threshold
Correct answer: Item Response Theory (IRT) algorithm parameters and exposure control rules
CAT platforms use IRT-based algorithms and exposure controls to select items matching the estimated candidate ability level while preventing overuse of any single item.
Question 5: A CBT platform administrator must ensure that candidates with documented disabilities receive the correct accommodations automatically. Where should accommodation flags be stored?
- In a spreadsheet emailed to proctors before each exam
- In the candidate's profile within the testing platform, linked to their registration (Correct answer)
- In a separate HR system inaccessible to the testing platform
- Posted on the testing center bulletin board
Correct answer: In the candidate's profile within the testing platform, linked to their registration
Storing accommodation flags in the candidate's platform profile ensures they are automatically applied when the candidate logs in, reducing human error.
Question 6: When conducting a disaster recovery drill for a CBT platform, which metric measures how quickly the system can be restored to full operation after a failure?
- Recovery Point Objective (RPO)
- Recovery Time Objective (RTO) (Correct answer)
- Mean Time Between Failures (MTBF)
- Service Level Agreement (SLA) uptime percentage
Correct answer: Recovery Time Objective (RTO)
Recovery Time Objective (RTO) is the maximum acceptable time to restore the platform to operational status after a disaster.
Question 7: A testing organization needs to purge candidate exam data in compliance with a data retention policy. Which administrative practice ensures proper execution without accidental data loss?
- Delete all records older than the retention period immediately
- Archive data to a secure offline location before deletion, then delete after verification (Correct answer)
- Overwrite records with placeholder data
- Transfer data to a public cloud bucket and remove from the primary database
Correct answer: Archive data to a secure offline location before deletion, then delete after verification
Archiving before deletion provides a recovery window in case of error, while subsequent deletion fulfills the policy requirement.
