Difficulty: EasyAzure Subscription Management and Cost Control

An administrator creates a monthly budget named `Dev-Budget` for an Azure subscription. The budget is set to 500.Theadministratorwantstoensurethattheyarenotifiedviaemailwhentheactualsubscriptioncostexceeds90500. The administrator wants to ensure that they are notified via email when the actual subscription cost exceeds 90% of the budget. However, during the first month, the cost reaches 475, but no email notifications are received. What is the most likely cause of this issue?

  1. A
    The budget inherits a default configuration that automatically routes alerts only to the Account Administrator.
  2. B
    The subscription has a ReadOnly resource lock applied, which prevents Azure Cost Management from processing the budget metrics.
  3. The administrator did not specify email recipients or associate an action group with the budget alert thresholds.Answer
  4. D
    The administrator lacks a specific Azure RBAC role at the subscription level, which blocks automated system emails from being delivered.

Answer

The administrator did not configure any email recipients or action groups for the budget alert thresholds.
The correct answer is that no email recipients or action groups were configured. Azure Cost Management budgets do not have default notification paths. When configuring a budget threshold (such as 90% of the budget), the administrator must explicitly enter email addresses or associate an action group to receive the notification.

Step-by-Step Solution

1
Analyze the budget scenario and check why the expected alert was not sent despite the cost (475)exceeding90475) exceeding 90% of the 500 budget ($450).
The cost has crossed the threshold, meaning an alert should have been triggered.
To verify that the threshold logic itself was met.
2
Review the configuration requirements for Azure budget alerts.
Azure budgets require defining either email recipients or an action group at the specific threshold level to send any notifications.
Without configuring recipients or action groups, the alert triggers silently with no action taken.

Key Concept

Azure budgets require explicit configuration of email recipients or action groups at the threshold level to send notifications.
