Oracle Cloud Infrastructure 2022 Architect Professional — Question 22

A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) in two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is intermittent due to the damages caused to the electrical grid.
In this scenario, what is the most effective configuration to use to migrate the data to OCI given the time constraints?

Answer options

• A. Set up an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.
• B. Upload the data to OCI using OCI Object Storage multipart upload tool.
• C. Set up a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using CCI Storage Gateway Cloud Sync tool.
• D. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
• E. Set up a hybrid network by launching a 1Gbps FastConnect virtual circuit between your data center and OCI. Use OCI Object Storage multipart upload tool to automate the migration of your data to OCI.

Correct answer: D

Explanation

The correct answer is D because using multiple OCI Data Transfer Appliances allows for physically shipping large amounts of data to OCI, which is faster and more reliable given the poor internet connection. The other options rely on internet connectivity, which is unstable in this scenario, making them less effective for the urgent migration needed.
