Oracle Cloud Infrastructure 2020 Architect Associate — Question 1

A financial firm is designing an application architecture for its online trading platform that must have high availability and fault tolerance.
Their solutions architect configured the application to use an Oracle Cloud Infrastructure 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 must not be affected 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 disruptions and ensure data durability?

Answer options

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

Correct answer: D

Explanation

The correct answer is D because creating a replication policy ensures that data is continuously copied to a different bucket in another OCI region, thus maintaining durability and availability even if one region fails. Options A and B do not provide true redundancy across regions, and option C does not relate to Object Storage and does not ensure data durability in the event of a regional outage.
