1 / 5
Fill in: 'We ___ a kill switch on every experiment flag so a regressing metric can be reverted in seconds without a new deploy.'
We 'wire a kill switch' — the standard, established feature-flag collocation for connecting an emergency toggle to an experiment. The other options aren't the recognised term here.
2 / 5
Fill in: 'Shipping an experiment without a rollback plan can ___ a bad variant live for hours before anyone notices the regression.'
We say no rollback plan will 'leave' a bad variant live too long — the standard, natural collocation for the resulting risk. The other options aren't idiomatic here.
3 / 5
Fill in: 'We ___ the guardrail metric continuously during an experiment so a regression triggers a rollback before it's fully rolled out.'
We 'monitor' a metric — the standard collocation for ongoing observation of a value. The other options aren't idiomatic here.
4 / 5
Fill in: 'We ___ every user back to the control experience the instant a rollback is triggered, not just new visitors going forward.'
We 'revert' users — the standard, established collocation for restoring the previous experience after a rollback. The other options aren't the recognised term here.
5 / 5
Fill in: 'We ___ a rollback drill on a low-stakes experiment periodically so the kill switch is proven to actually work before it's needed for real.'
We 'run a drill' — the standard, simple collocation for executing a practice exercise. The other options are less idiomatic here.
