1Z0-1067-25 Question 90
Single answerYour organization is required by compliance regulations to retain application logs for seven years, ensuring they remain tamper-proof and cost-effective. Currently, logs are uploaded daily to Oracle Cloud Infrastructure (OCI) Object Storage in the Standard tier. How can you implement a retention strategy that meets these requirements and optimizes costs?
- A
Configure a single Standard Object Storage bucket and rely on manual deletions after seven years to manage retention.
- B
Use a Lifecycle Policy to move objects older than 90 days from the Standard tier to Archive Storage and configure Object Storage retention rules to prevent deletion before seven years.
- C
Keep logs on Block Volume and create incremental backups every week to maintain seven years of data.
- D
Utilize local ephemeral storage on compute instances, then archive them to Archive Storage only when running out of capacity.
Show answer and explanation
Correct answer: B
Explanation
Implementing data retention strategies in OCI typically involves using Object Storage lifecycle policies to automatically transition data from the Standard tier to the Archive tier, combined with retention lock features (Object Storage retention rules) to meet compliance requirements. According to Oracle documentation, Archive Storage provides a lower-cost option for long-term data retention, while Lifecycle Policies enforce automated movement of objects after a defined period. Retention rules prevent premature deletion, ensuring compliance with seven-year regulatory mandates.
- A. Incorrect.
Option 1 is incorrect because relying solely on manual deletions is prone to error and doesn�t ensure tamper-proof retention. There is no automated mechanism preventing accidental or premature deletions.
- B. Correct.
Option 2 is correct. Creating a Lifecycle Policy to automatically transition older objects to Archive Storage minimizes costs, and configuring retention rules will ensure logs cannot be deleted before the seven-year compliance period has passed.
- C. Incorrect.
Option 3 is incorrect because storing logs on Block Volume and taking incremental backups is more expensive for long-term data retention compared to using Object Storage Standard + Archive tiers. It also lacks the automated retention enforcement Object Storage can provide.
- D. Incorrect.
Option 4 is incorrect because ephemeral storage is not intended for long-term data retention. It can be lost when an instance is stopped or terminated, and relying on it before archiving logs is risky and does not enforce the required retention period.
