• The number of email messages that Alert1 will send in an hour is
  0461260
• The number of SMS messages that Alert2 will send in an hour is
  0461260

Explanation

Azure Monitor Action Groups enforce a rate limit of 1 SMS every 5 minutes and up to 100 emails per hour, resulting in 12 SMS messages and 60 emails for an alert triggering every minute.

Approach. The scenario states that the alert criteria is triggered every minute, meaning the alert will fire 60 times in an hour. Azure Monitor applies rate limits to Action Groups to prevent notification spam. The rate limit for SMS messages is strictly 1 message every 5 minutes per phone number. Therefore, in a 60-minute period, only 12 SMS messages (60 minutes / 5 minutes) will be sent, and the rest are dropped. For emails, the rate limit is a maximum of 100 emails per hour per email address. Because 60 triggers is below the 100-email threshold, all 60 email notifications will be successfully sent.

Common mistakes.

• common_mistake. A common mistake is selecting '60' for the SMS messages, which happens if a candidate assumes there are no rate limits and all triggered notifications are sent. Another mistake is applying the 5-minute SMS rate limit to emails and selecting '12' for emails as well.
