Exam MS-101 topic 2 question 97 discussion

7 days to establish baseline and alerts will not be triggered during this time - https://docs.microsoft.com/en-us/microsoft-365/compliance/alert-policies?view=o365-worldwide - Applicable section starts with " When the alert is triggered "

Correct

If you select the setting based on unusual activity, Microsoft establishes a baseline value that defines the normal frequency for the selected activity. It takes up to seven days to establish this baseline, during which alerts won't be generated. After the baseline is established, an alert is triggered when the frequency of the activity tracked by the alert policy greatly exceeds the baseline value https://learn.microsoft.com/en-us/microsoft-365/compliance/alert-policies?view=o365-worldwide&viewFallbackFrom=o365-worldwide%20-%20Applicable%20section%20starts%20with%20%22%20When%20the%20alert%20is%20triggered%20%22

Note: it may take up to a week for the baseline to be established for anomaly alerts. Until then this alert will not be triggered.
