1Z0-1072-25 Question 186
Select 2Your e-commerce application on Oracle Cloud Infrastructure (OCI) stores thousands of product images. These images must be accessible globally with minimal latency and protected against regional outages. As the images become outdated, they are accessed less frequently and need to be stored more cost-effectively. You plan to implement cross-region replication and take advantage of different Object Storage tiers. Which two options should you use to meet these requirements?
- A
Store all images in the Standard tier of Object Storage and enable cross-region replication for that bucket.
- B
Use only the Archive tier for all images and rely entirely on remote retrieval to fulfill global access requirements.
- C
Create a separate bucket for newly uploaded images, use lifecycle policies to transition older images to the Archive tier, and enable cross-region replication on the Standard tier bucket.
- D
Store images on local NVMe SSDs attached to compute instances for high performance and periodically replicate them to another region using Object Storage.
Show answer and explanation
Correct answers: A, C
Explanation
By combining cross-region replication for the Object Storage Standard tier and lifecycle policies to transition older images to Archive, you strike a balance between performance, global availability, and cost savings. OCI Object Storage cross-region replication ensures data durability, while lifecycle policies automate the move of infrequently accessed data to lower-cost storage. For more information, refer to the OCI documentation on Object Storage tiers, lifecycle management, and cross-region replication best practices.
- A. Correct.
Option 1 is correct. Placing all images initially in the Standard tier and enabling cross-region replication ensures high availability, immediate access, and redundancy in OCI. This satisfies the need for minimal latency and regional resilience.
- B. Incorrect.
Option 2 is incorrect. Using only the Archive tier for all images is not suitable for frequently accessed data. Archive storage is designed for rarely accessed data, and retrieval times can be significantly longer, which fails the requirement for minimal latency.
- C. Correct.
Option 3 is correct. By placing new (frequently accessed) images in the Standard tier, you ensure immediate availability. Lifecycle policies allow you to move older images to the Archive tier as their access frequency decreases, reducing costs. Simultaneously, enabling cross-region replication on the Standard tier bucket protects against regional outages.
- D. Incorrect.
Option 4 is incorrect. While local NVMe SSDs provide fast storage, they are ephemeral and not ideal for long-term or cross-region redundancy. Reliance on manual replication to Object Storage introduces operational overhead and potential for data loss if replication is not kept current.
