Oracle Cloud Infrastructure 2022 Architect Associate — Question 29

A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance.
Their solutions architect configured the application to use an Oracle Cloud Infrastructure (OCI) Object Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial data. The stored financial data in the bucket should not be impacted even if there is an outage in one of the Availability Domains or a complete region.
What should the architect do to avoid any costly service disruption and ensure data durability?

Answer options

• A. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
• B. Create a replication policy to send data to a different bucket in another OCI region.
• C. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
• D. Copy the Object Storage bucket to a block volume.

Correct answer: B

Explanation

The correct answer is B because creating a replication policy to send data to a different bucket in another OCI region ensures that the data remains available even if there is a failure in the primary region. Option A does not provide immediate data redundancy, Option C introduces unnecessary complexity without guaranteeing immediate fault tolerance, and Option D does not align with best practices for object storage data management.
