Final answer:
1-minute interval granularity request history for key requests is available for 30 days, allowing detailed logs of activity to be accessed for this duration for analysis or troubleshooting in technological contexts.
Step-by-step explanation:
The correct answer to the question "For a key request, how long is 1-minute interval granularity request history available for?" is option c) 30 days. When dealing with data granularity in key requests, particularly in various computing or web services, a 1-minute interval granularity often refers to the level of detail maintained in the logging of requests. For an interval granularity for a history of key requests to be available for 30 days means that detailed logs of activity at 1-minute intervals are stored and can be accessed for this duration before they are archived or aggregated into less granular formats. This can be essential for analysis or troubleshooting purposes in a technology or computing environment.
