1Z0-1072-25 Question 287
Single answerYou are an OCI Cloud Architect tasked with establishing cross-region replication for a mission-critical file system in Oracle Cloud Infrastructure. You have already created the file system in the source region and set up the replication target in the destination region. However, replication does not start. Which additional step must you perform to ensure the replication process begins successfully?
- A
Configure a new mount target in the source region� subnet to initiate replication.
- B
Define an IAM policy that grants the File Storage service permission to replicate from the source to the destination region.
- C
Enable data encryption using a custom vault key on the destination file system.
- D
Take a manual snapshot of the file system in the destination region to trigger replication.
Show answer and explanation
Correct answer: B
Explanation
In OCI File Storage, when you configure cross-region replication, you must grant the File Storage service permission to replicate data from the source to the destination region. This is typically done through an IAM policy that references the source and target compartments and regions. Without this step, replication cannot proceed. For more details, refer to Oracle� File Storage service documentation for best practices on setting up cross-region replication and configuring the required IAM policies.
- A. Incorrect.
Incorrect. Creating or modifying mount targets in the source region alone does not initiate replication for File Storage. Mount targets provide access to the file system but are not the required step to begin cross-region replication.
- B. Correct.
Correct. You must create (or update) an Oracle Cloud Infrastructure IAM policy granting the File Storage service the necessary permission to replicate data between the source and destination regions. Without this policy, replication will remain stalled.
- C. Incorrect.
Incorrect. Although encryption is important, simply encrypting the destination file system does not initiate replication. Encryption settings do not replace the requirement for the correct IAM policy.
- D. Incorrect.
Incorrect. Taking a manual snapshot of the destination file system does not trigger data movement from the source. Replication depends on the source file system and the relevant IAM permissions to start and maintain data synchronization.
