1Z0-1067-25 Question 131
Select 2Your team needs to monitor free disk space for a set of Compute instances. You have created a custom metric named 'freeDiskSpace' that reports the remaining disk space in gigabytes. You must set up an alarm to trigger when the average free disk space across all instances drops below 10 GB for 10 consecutive minutes. The alarm should then send a single email notification to your operations team and automatically resolve when the metric returns above 10 GB. Which two actions are required to meet these requirements?
- A
Create a Notification Topic for email alerts, subscribe the operations team� email address, and reference this topic in the alarm configuration.
- B
Set the alarm� message format to JSON for automatic resolution of the alarm when the threshold is no longer exceeded.
- C
Use the 'Mean' aggregator on the 'freeDiskSpace' metric and specify a threshold condition of <10 for an interval of 10 minutes.
- D
Enable the Repeat Notification feature so that the alarm automatically transitions to 'OK' when the metric recovers above the threshold.
- E
In the alarm definition, select 'Auto-Resolve' to ensure the alarm returns to 'OK' status when the disk space metric rises above the threshold.
Show answer and explanation
Correct answers: A, C
Explanation
To implement an alarm and notifications in OCI, you create or use an existing Notification Topic, subscribe your desired channels (e.g., email), and reference that topic within the alarm. The alarm� query must specify the relevant metric, aggregator (such as 'Mean'), threshold, and duration window (10 consecutive minutes). Once the metric no longer meets the firing criteria, OCI Monitoring automatically transitions the alarm from 'FIRING' to 'OK.' Refer to the Oracle Cloud Infrastructure Monitoring documentation for additional guidance on setting thresholds and defining alarm conditions.
- A. Correct.
Option 1 is correct. You need to create a Notification Topic and subscribe the email address(es) to receive alerts. Then, you reference this topic in the alarm� configuration to ensure your operations team is notified.
- B. Incorrect.
Option 2 is incorrect. The message format (JSON, raw text, or Slack notifications) does not control whether an alarm auto-resolves. The format primarily affects how the message content is delivered, not how the alarm state transitions.
- C. Correct.
Option 3 is correct. Aggregating the metric using 'Mean' allows you to watch for the average free disk space across all instances. Specifying a threshold of <10 for a 10-minute window meets the requirement for consecutive minutes under 10 GB.
- D. Incorrect.
Option 4 is incorrect. The 'Repeat Notification' feature governs how frequently you receive alerts while the alarm is in a firing state, not whether it resolves automatically.
- E. Incorrect.
Option 5 is incorrect. There is no single 'Auto-Resolve' setting that you must enable. In OCI Monitoring, alarms automatically transition back to 'OK' status when the metric is above the threshold. You only need to configure the threshold and query properly.
