Oracle Cloud Infrastructure 2022 Architect Professional — Question 27

You are a solutions architect for a global health care company, which has numerous data centers around the globe. Due to the increasing volume of data that your company stores, you are tasked with setting up a durable, cost-effective solution to archive data from existing on-premises tape-based backup infrastructure to Oracle Cloud Infrastructure (OCI).
Which is the most effective mechanism to implement this requirement?

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. Set up an on-premises OCI Storage Gateway, which will back up your data to the OCI Object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from the Standard to the Archive tier.
• C. Set up FastConnect to connect your on-premises network to OCI VCN and use the rsync tool to copy your data to the OCI Object Storage Archive tier.
• D. Set up an on-premises OCI Storage Gateway, which will back up your data to the OCI Object Storage Archive tier.
• E. Set up an on-premises OCI Storage Gateway, which will back up your data to the OCI Object Storage Standard tier.

Correct answer: D

Explanation

The correct answer is D, as using an on-premises OCI Storage Gateway to back up data directly to the OCI Object Storage Archive tier is the most cost-effective method for archiving data. Option A is incorrect since the File Storage Service is not intended for archiving data. Option B incorrectly uses the Standard tier for initial storage, which is not optimal for archiving. Option C involves unnecessary complexity with FastConnect and the rsync tool. Option E also does not address archiving effectively by using the Standard tier.
