1Z0-1067-25 Question 130
Single answerYou have created a custom alarm in Oracle Cloud Infrastructure (OCI) to alert your team when CPU usage for a specific Compute instance remains above 80% for 5 minutes. You configured the alarm to send email notifications through the OCI Notifications service, but no one has received any email alerts despite the threshold being exceeded for the required duration. Which step must be performed to ensure that recipients successfully receive the alarm notifications?
- A
Add an IAM policy that grants the email addresses permission to read the alarm metric data.
- B
Confirm each email subscription in OCI so that the email addresses can receive notifications.
- C
Use the �Messages� dashboard in the Notifications service to mark the subscription as active.
- D
Include an alarm suppression rule that allows notifications to flow through when the threshold is breached.
Show answer and explanation
Correct answer: B
Explanation
In OCI, when you create an email subscription for an alarm, the recipient must confirm their subscription by following a link sent to the specified email address. Without this confirmation, Oracle Cloud Infrastructure will not send any notifications to that address. Refer to the official OCI Notifications documentation for details on subscription workflows and required confirmations: https://docs.oracle.com/en-us/iaas/Content/Notification/Concepts/overview.htm.
- A. Incorrect.
Option 1 is incorrect. IAM policies control resource access, not the subscription confirmation process. This would allow or deny certain operations but wouldn�t enable delivery of email notifications.
- B. Correct.
Option 2 is correct. When setting up an email subscription, the user must confirm (opt-in) from the received confirmation email. If the subscription remains unconfirmed, OCI will not deliver any notifications to that address.
- C. Incorrect.
Option 3 is incorrect. There is no �Messages� dashboard that enables manual activation of subscriptions. Subscriptions specifically require user confirmation via email to become active.
- D. Incorrect.
Option 4 is incorrect. An alarm suppression rule is used to temporarily pause alarm notifications under certain conditions. It does not help in making an email subscription active.
