1Z0-1072-25 Question 1
Single answerYou have a high-traffic application running on an Oracle Cloud Infrastructure compute instance that uses ephemeral local NVMe storage for caching. The instance currently writes its application logs to the same ephemeral storage, but your compliance requirements mandate retaining logs for at least 6 months. Which approach best meets these requirements while minimizing the risk of data loss?
- A
Configure a larger shape with more local NVMe storage to store logs
- B
Enable auto-scaling for the compute instance to handle increased logs
- C
Attach an OCI Block Volume and upload the logs to it occasionally
- D
Rotate the logs to OCI Object Storage on a regular schedule
Show answer and explanation
Correct answer: D
Explanation
Ephemeral local NVMe storage on OCI compute instances is not persistent and can be lost immediately if the instance fails, is stopped, or is reconfigured. For compliance and audit requirements that demand long-term log retention, rotating or archiving logs to a durable storage option like OCI Object Storage is the recommended practice. Refer to Oracle� Compute and Storage documentation for best practices on using local NVMe storage only for short-lived data (such as cache), and storing critical or long-lived data on Block Volumes or Object Storage.
- A. Incorrect.
Incorrect: While a larger shape might temporarily provide more local NVMe capacity, ephemeral storage is not persistent. If an instance fails or is retired, data is lost. This does not address long-term retention with minimal data loss risk.
- B. Incorrect.
Incorrect: Auto-scaling can handle additional load by adding more compute instances, but it does not inherently solve the log retention issue. Logs stored on ephemeral local storage remain vulnerable to data loss when instances are scaled down or fail.
- C. Incorrect.
Incorrect: Attaching a Block Volume can provide persistent storage, but merely uploading logs occasionally still carries a risk of data loss if the instance fails before the upload. Additionally, continuously writing large log volumes to a Block Volume can become costly and complex for long-term compliance.
- D. Correct.
Correct: Regularly rotating logs to OCI Object Storage ensures durability and long-term retention. Object Storage is designed for high durability and scalability, making it a best practice for storing logs that need to be retained for extended periods.
