For which time period does 'earliest=-1h' represent?

  1. Last hour

  2. Last minute

  3. Last day

  4. Last week

The correct answer is: Last hour

The time specification 'earliest=-1h' refers to a time window that starts one hour ago from the current time and continues until the present moment. This means it captures all events that occurred in the last hour. The term "-1h" indicates a relative offset from the current time, which is a common way to specify time frames within the Splunk querying language. The other options represent different time frames but do not align with the meaning of 'earliest=-1h'. For example, 'last minute' would use '-1m' to signify just the last 60 seconds, while 'last day' or 'last week' would require '-1d' or '-1w', respectively, to indicate those longer time periods. Thus, understanding the syntax and meaning of these expressions is critical in accurately representing the desired time range in Splunk queries.
