Oracle Cloud Infrastructure 2019 Developer Associate — Question 149

You are designing a shared storage solution for your company in Oracle Cloud Infrastructure. The proposed storage solution should allow users to create a hierarchical structure (similar to the directory structure in Linux or Windows based systems). The solution should provide data encryption and a large amount of storage space.
Which would be the best implementation strategy?

Answer options

• A. Use block storage. Create and attach a large block storage volume to one compute instance. Assign a public IP to the compute instance. Store data on the block storage and access it by connecting to the compute instance.
• B. Use object storage. Create a single namespace and multiple buckets to create the hierarchical directory structure.
• C. Use object storage. Create multiple namespaces with one bucket each. Make the buckets publicly accessible.
• D. Use file storage service. Create a file system and a mount target. Share the private IP of the mount target.

Correct answer: D

Explanation

The correct answer is D because using the file storage service allows for the creation of a file system that supports a hierarchical directory structure, which aligns with the requirements. Options A and B do not provide the necessary directory structure, while option C compromises security by making buckets publicly accessible.
