FIDO Quality Control & Process Improvement 5

Question 1

A FIDO implementation team introduces 'error budgets' inspired by Site Reliability Engineering (SRE). How does an error budget relate to quality control for a WebAuthn relying party?

Accepted Answer

It defines the acceptable failure rate per SLA period; exceeding it triggers a quality improvement sprint instead of new feature work

Answer

It sets the maximum number of bugs allowed per sprint

Answer

It allocates budget for purchasing error-detection tools

Answer

It determines how many test cases can be skipped per release

Question 2

A FIDO authenticator QA team wants to prioritize test cases by risk. Which factor is LEAST relevant when assessing risk for a specific test case?

Accepted Answer

The color of the test case documentation template

Answer

Likelihood of the failure mode occurring in production

Answer

Severity of impact if the requirement is violated

Answer

Historical defect density in the code module under test

Question 3

When a FIDO metadata statement is updated in the FIDO Metadata Service (MDS), what quality control step should a relying party perform before applying the update?

Accepted Answer

Validate the updated metadata statement's signature against the MDS root certificate before trusting the new data

Answer

Immediately apply the update without verification to minimize delay

Answer

Delete all existing authenticator registrations

Answer

Disable attestation verification during the update window

Question 4

A process improvement initiative uses value stream mapping for FIDO authenticator certification. Which type of time in the value stream should be minimized?

Accepted Answer

Wait time between process steps (queue time)

Answer

Active testing time

Answer

Time spent fixing genuine defects

Answer

Time for security review

Question 5

A FIDO certification lab uses acceptance sampling to inspect a batch of authenticator tokens. The lot is rejected. What does this mean for the batch?

Accepted Answer

The entire batch fails the quality gate because the sampled defect rate exceeded the acceptable quality level (AQL)

Answer

Only the specific sampled units are rejected

Answer

The batch must be retested with a larger sample

Answer

The certification lab must renegotiate the AQL with the vendor

Question 6

A FIDO server team adopts continuous integration (CI) with automated conformance test runs on every commit. Which quality benefit does this primarily provide?

Accepted Answer

Immediate feedback on whether a commit breaks FIDO specification compliance, reducing the cost of defect fixes

Answer

Elimination of the need for manual security review

Answer

Guaranteed zero defects in production

Answer

Automatic deployment to production upon test passage

Question 7

Which process improvement model, widely used in software quality, defines five maturity levels from 'Initial' to 'Optimizing' and could be applied to a FIDO authenticator development organization?

Accepted Answer

CMMI (Capability Maturity Model Integration)

Answer

ITIL (Information Technology Infrastructure Library)

Answer

TOGAF (The Open Group Architecture Framework)

Answer

COBIT (Control Objectives for Information and Related Technologies)
