1Z0-1072-25 Question 184
Single answerYour organization needs to store transaction logs for seven years to meet compliance requirements. The logs are frequently accessed during the first 90 days, but access requirements drop drastically after that period. However, the compliance team needs the ability to retrieve any log within about four hours if required for an audit. Which approach should you implement to meet these requirements while minimizing storage costs in Oracle Cloud Infrastructure?
- A
Store all logs solely in Block Volumes and create weekly incremental backups.
- B
Keep logs on Object Storage Standard tier for the entire seven-year period.
- C
Use Object Storage Standard for the first 90 days and then automatically move data to Archive Storage tier thereafter.
- D
Save logs in ephemeral local NVMe drives and replicate them across Availability Domains.
Show answer and explanation
Correct answer: C
Explanation
Oracle Cloud Infrastructure provides a cost-effective approach to long-term data retention by utilizing both Standard and Archive tiers in Object Storage. Logs can be kept in Standard for active use (e.g., the first 90 days) and then transitioned automatically to Archive for significantly lower cost. Archive Storage retrieval times (up to four hours) meet the compliance requirement. For more details, refer to Oracle� official documentation on Object Storage lifecycle policies and Archive Storage best practices.
- A. Incorrect.
Option 1: Storing logs in Block Volumes and creating weekly backups is feasible for shorter retention, but it quickly becomes expensive and is not designed as a low-cost long-term archival solution. Although backups can be used to recover data, the cost over seven years would not be minimal compared to Archive Storage.
- B. Incorrect.
Option 2: Keeping logs in the Standard tier for seven years ensures fast access but does not minimize costs for rarely accessed data. Standard Object Storage, while durable and highly available, is more expensive compared to the Archive tier for long-term retention.
- C. Correct.
Option 3: Using the Standard tier for the initial 90 days (when logs are still being frequently accessed) and then moving them to the Archive Storage tier is the most cost-effective strategy for long-term retention in OCI. Archive Storage offers significantly lower costs while still allowing retrieval within a four-hour window, matching the compliance requirement.
- D. Incorrect.
Option 4: Ephemeral local NVMe drives are not suitable for long-term retention because they are temporary and data can be lost if the compute instance is stopped or terminated. This undermines the durability and availability needed for compliance logs.
