1Z0-1072-25 Question 288
Single answerYou have a mission-critical application that stores data in an OCI File Storage service in the Phoenix region. Your organization wants to set up asynchronous File Storage replication to the Ashburn region for disaster recovery. After creating and enabling a replication between the Phoenix file system and a file system in Ashburn, which action must you take to ensure the application can read and write to the replicated file system in Ashburn if you switch over to that region?
- A
Create a new mount target in Ashburn and associate the replicated file system with it for client access
- B
Enable replication on the Phoenix mount target so it automatically appears in the Ashburn region
- C
Modify your DNS records so that the Phoenix mount target IP forwards traffic to the Ashburn file system
- D
Configure the replication to use a single shared mount target by specifying the mount target� IP in both regions
Show answer and explanation
Correct answer: A
Explanation
To leverage cross-region replication for disaster recovery or failover, you must set up a distinct environment in the target region (Ashburn), including creating a mount target that references the replicated file system. This step ensures that clients can mount and access the file system locally in the event that the Phoenix region becomes unavailable. Refer to the OCI File Storage documentation regarding replication and regional resources for best practices.
- A. Correct.
Correct. In OCI, each region requires its own mount target to provide network access to a file system. After replication is established, you must create a distinct mount target in Ashburn to allow clients in that region to mount the replicated file system. This ensures the Ashburn environment can function independently if you fail over.
- B. Incorrect.
Incorrect. The mount target in Phoenix cannot simply 'appear' in Ashburn. Mount targets are regional constructs that must be created in each region to give clients a local access point.
- C. Incorrect.
Incorrect. DNS forwarding alone does not replicate or provide a local mount target in the Ashburn region. You need an actual mount target attached to the replicated file system in Ashburn for clients to mount it directly and perform I/O operations.
- D. Incorrect.
Incorrect. OCI File Storage replication does not support using the same mount target IP across regions. Each region requires its own mount target and network configuration to route to the local file system.
