Oracle Cloud Infrastructure 2020 Architect Professional — Question 21

You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were instructed to set up a durable, cost-effective solution to archive your data from your existing on-premises tape-based backup infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to implement this requirement? (Choose the best answer.)

Answer options

• A. Use the File Storage Service in OCI and copy the data from your existing tape-based backup to the shared file system.
• B. Setup an on-premises OCI Storage Gateway which will back up your data to OCI Object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.
• C. Setup FastConnect to connect your on-premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.
• D. Setup an on-premises OCI Storage Gateway which will back up your data to OCI Object Storage Standard tier.
• E. Setup an on-premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.

Correct answer: D

Explanation

The correct answer is D because it specifies backing up data to the OCI Object Storage Standard tier, which is suitable for frequently accessed data before potentially transitioning it to the Archive tier. Option A does not directly address OCI Object Storage, while B and C introduce unnecessary complexity with lifecycle management and FastConnect. Option E is incorrect as it does not align with the need for Standard tier storage initially.
