Oracle Cloud Infrastructure 2023 Architect Associate — Question 40

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. Copy the Object Storage bucket to a block volume.
• D. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.

Correct answer: B

Explanation

The correct answer is B because replicating data to a different bucket in another OCI region ensures that data remains accessible even if there is a failure in the original region. Option A does not provide the necessary redundancy for outages, Option C is not a valid method for ensuring data durability, and Option D may introduce delays and is not as efficient as a direct replication strategy.
