1Z0-1067-25 Question 132
Select 2You have created an alarm in Oracle Cloud Infrastructure (OCI) to monitor multiple Compute instances. The alarm is set to trigger when the average CPU utilization across these instances exceeds 75% for 5 minutes, and it should send notifications via Email and PagerDuty. However, your team is not receiving any notifications, even though metrics show the threshold is crossed. Which two actions must you take to ensure the alarm triggers and the notifications are successfully delivered?
- A
Place the alarm and the monitored resources in the same region and compartment
- B
Configure and confirm the subscription in the Notification Topic tied to the alarm
- C
Disable the alarm at the resource level to allow direct notifications
- D
Remove the filter condition from the alarm and rely on default values
- E
Create or validate an IAM policy allowing the alarm to publish to the Notification Topic
Show answer and explanation
Correct answers: A, B
Explanation
To ensure alarms function properly, you must place both the alarm and the monitored resources in the correct region and compartment so the alarm has valid metrics. Additionally, a Notification Topic must be configured, and at least one subscription to that topic must be confirmed for the intended protocol (e.g., Email, PagerDuty). You must also have a proper IAM policy allowing alarms to publish notifications. For more information, refer to Oracle Cloud Infrastructure Monitoring service documentation regarding alarm setup, metrics, and Notification Topics.
- A. Correct.
Option 1: Correct. Alarms and monitored resources must be in the same region and compartment. If they differ, the alarm will not detect the right metrics or may fail to trigger because it has no valid data to evaluate.
- B. Correct.
Option 2: Correct. Even if the alarm is triggered, notifications will not be sent unless at least one subscription is configured and confirmed in the linked Notification Topic. Confirming the subscription ensures that notifications go to the intended recipients.
- C. Incorrect.
Option 3: Incorrect. Disabling the alarm at the resource level does not enable direct notifications. In fact, disabling an alarm prevents it from triggering any notifications at all. This is a misunderstanding that would prevent alarms from working.
- D. Incorrect.
Option 4: Incorrect. Removing filter conditions from an alarm can cause an alarm to become overly broad or not function as intended. The default values may not align with your exact use case and can lead to incorrect or no triggers.
- E. Incorrect.
Option 5: Incorrect. You must have a valid policy that allows the Monitoring service to publish to the Notification Topic. Simply removing or not setting the policy will block the alarm from sending notifications. Adding or validating the IAM policy is the correct action, not removing it.
