Ensure Data Durability and Avoid Costly Disruptions | Exam 1Z0-1072-20
Question
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?

To ensure high availability and fault tolerance of the financial firm's online trading platform, the solutions architect has 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. However, in the event of an outage in one of the Availability Domains or a complete region, the stored financial data must not be affected. To achieve this goal and ensure data durability, the following solution can be implemented:
Option D: Create a replication policy to send data to a different bucket in another OCI region.
Explanation: Replicating the Object Storage bucket to a different OCI region provides a highly available and fault-tolerant solution that ensures data durability in the event of an outage in one of the Availability Domains or a complete region. A replication policy ensures that data is continuously and automatically copied to another Object Storage bucket located in a different OCI region.
Additionally, it's important to choose a different OCI region that is geographically distant from the original region to minimize the impact of any localized disasters. Also, it's important to consider the cost implications of replicating data to another region, as data transfer and storage costs may vary based on the destination region.
Option A: Creating a new Object Storage bucket in another region and configuring a lifecycle policy to move data every 5 days is not a reliable solution for ensuring data durability in the event of an outage in one of the Availability Domains or a complete region. Data can be lost if an outage occurs before the data is moved to another region.
Option B: Creating a lifecycle policy to regularly send data from Standard to Archive storage does not provide high availability and fault tolerance in the event of an outage in one of the Availability Domains or a complete region. Archive storage is designed for long-term data retention and retrieval and is not recommended for high-availability or frequently accessed data.
Option C: Copying the Object Storage bucket to a block volume does not provide high availability and fault tolerance in the event of an outage in one of the Availability Domains or a complete region. Block volumes are designed for performance-intensive workloads and are not recommended for long-term data retention or durability.
