1 / 5
Fill in: 'The SRE team must ___ any planned database maintenance changes at least 48 hours in advance.'
We 'announce changes' — 'announce' is the standard collocation for making a formal, proactive public statement about upcoming work. 'Communicate changes' is broader and less specific; 'share changes' is informal; 'notify changes' requires a preposition ('notify teams of changes') and focuses on the recipient rather than the act.
2 / 5
Fill in: 'We have a change freeze in December, so we need to ___ downtime with all teams before then.'
We 'coordinate downtime' — 'coordinate' implies aligning multiple stakeholders with different dependencies around a single maintenance window. 'Schedule downtime' focuses on picking a time slot; 'plan downtime' is broader; 'arrange downtime' is informal and focuses on logistics rather than multi-team alignment.
3 / 5
Fill in: 'Before applying the Kubernetes upgrade, we must ___ the rollback procedure to ensure we can revert quickly.'
We 'test a rollback' — 'test' is the standard collocation for empirically verifying that a rollback procedure works before it is needed in an emergency. 'Verify' implies checking documentation rather than executing the procedure; 'practice' is close but more informal; 'validate' is formal but used more for requirements and schemas than procedures.
4 / 5
Fill in: 'To reduce blast radius, the team decided to ___ the change incrementally across ten regions over two weeks.'
We 'deploy incrementally' — 'deploy incrementally' is the infrastructure standard for releasing changes in small, controlled batches. 'Roll out' is also correct and focuses on the progressive distribution; 'release' is more product-focused; 'push incrementally' is informal and often refers to pushing code to a repository rather than deploying to infrastructure.
5 / 5
Fill in: 'After the final region was updated, the team ran a full health check to ___ stability across the fleet.'
We 'confirm stability' — 'confirm' implies performing a definitive final check that results in formal sign-off that the system is healthy. 'Verify stability' is close but more process-oriented; 'check stability' is informal; 'ensure stability' describes a commitment rather than an action taken after the fact.
