Question 1

What does 'uptime SLA' mean for a CBT platform provider contracted with a US credentialing organization?

Accepted Answer

A contractual guarantee that the testing platform will be available for a defined percentage of time, such as 99.9%

Answer

An uptime SLA (Service Level Agreement) holds the platform vendor accountable for availability, specifying penalties or remedies if downtime exceeds agreed thresholds.

Question 2

What is the benefit of using 'cloud-based' CBT infrastructure compared to on-premises servers?

Accepted Answer

It provides elastic scalability to handle exam volume spikes without over-provisioning permanent hardware

Answer

Cloud infrastructure scales compute and storage resources on demand, accommodating sudden surges (e.g., a national certification exam day) without costly permanent hardware.

Question 3

How does 'multi-factor authentication' (MFA) improve security for CBT platform administrators?

Accepted Answer

It requires two or more verification methods before granting access, reducing the risk of unauthorized logins

Answer

MFA combines something known (password) with something possessed (phone/token) or something inherent (biometric), making account compromise significantly harder.

Question 4

What is 'audit logging' and why is it required in US CBT platforms handling sensitive assessment data?

Accepted Answer

Creating tamper-evident records of all system events, user actions, and data access for compliance and forensic review

Answer

Audit logs provide an immutable trail of who accessed what data and when, satisfying legal, regulatory, and accreditation requirements for test security and data governance.

Question 5

Which emerging technology is being explored to further secure CBT item delivery and prevent content theft?

Accepted Answer

Blockchain-based item provenance tracking

Answer

Blockchain provides an immutable, distributed ledger that can log item exposure, detect unauthorized copying, and verify item integrity across exam administrations.
