1Z0-1072-25 Question 274
Single answerYou have an existing production file system in Oracle Cloud Infrastructure (OCI) File Storage that hosts critical data for your e-commerce application. Your development team needs a new environment that mirrors the production data at a specific point in time, but they also need the flexibility to make changes without impacting the production file system. Which action should you take to meet these requirements with minimal overhead?
- A
Use the existing production file system in read-only mode for development tasks.
- B
Take a snapshot of the production file system and then create a clone from that snapshot for the new environment.
- C
Export the production file system as an NFS share to the development environment and perform a local copy of all data.
- D
Schedule a replication job to a different region, then rename the replicated file system for development use.
Show answer and explanation
Correct answer: B
Explanation
In OCI File Storage, a snapshot provides a point-in-time view of the file system, while a clone created from that snapshot offers immediate read-write access. This method is highly efficient because the clone shares underlying data blocks with the snapshot until changes are made. It reduces both storage overhead and creation time, making it an ideal solution for quickly spinning up development or testing environments. For more details, see the Oracle Cloud Infrastructure File Storage documentation on managing snapshots and cloning (docs.oracle.com/en-us/iaas).
- A. Incorrect.
Option 1 is incorrect because using the production file system in read-only mode does not allow the development team to modify data independently without risking production data integrity.
- B. Correct.
Option 2 is correct. Taking a snapshot and then creating a clone from that snapshot is the recommended approach in OCI File Storage, as the clone provides a fully writable environment with minimal overhead and does not affect the original file system.
- C. Incorrect.
Option 3 is incorrect because manually copying data over NFS is time-consuming and creates unnecessary overhead on both the production system and the network. It also lacks the advantages of snapshot-based cloning, such as instant creation.
- D. Incorrect.
Option 4 is incorrect because replicating to a different region is typically used for disaster recovery or multi-region requirements. It is not the most efficient way to create a local development environment that clones production data at a specific point in time.
