Oracle Cloud Infrastructure 2020 Architect Professional — Question 20
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 service to use to migrate the data to OCI given the time constraints? (Choose the best answer.)
Answer options
- A. Use multiple OCI Data Transfer Appliances to transfer data to OCI.
- B. Setup an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.
- C. Setup 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.
- D. Setup an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
- E. Upload the data to OCI using OCI Object Storage multipart upload tool.
Correct answer: A
Explanation
The correct answer is A because using multiple OCI Data Transfer Appliances allows for the rapid physical transfer of large data volumes, which is crucial given the time constraints and unstable internet connection. Other options involve methods that rely on potentially unreliable internet connections or slower transfer speeds, which would not meet the urgent requirement of migrating 300 TB in two weeks.
