1Z0-1072-25 Question 199
Select 2Your organization is implementing a disaster recovery (DR) strategy for multiple Compute instances running in Oracle Cloud Infrastructure (OCI). You need a reliable method to replicate both boot and block volumes to a secondary region so you can quickly recover services in the event of a primary region outage. Which two actions are valid approaches to achieve cross-region replication of these volumes? (Choose two.)
- A
Perform periodic volume backups in the primary region and copy the backups to the DR region.
- B
Enable Instance Principals on your Compute instances to automatically replicate their attached volumes to the DR region.
- C
Clone the volumes within the primary region and then attach the clones to instances in the DR region.
- D
Use Cross-Region Block Volume Replication (if enabled in your tenancy) from the Block Volume console or APIs.
- E
Export the volumes as an Object Storage image and perform a multipart upload of the volume data to the DR region.
Show answer and explanation
Correct answers: A, D
Explanation
OCI offers multiple strategies for replicating or copying volumes across regions to support disaster recovery. The two main approaches are: (1) using volume backups in the primary region and copying those backups to the DR region, and (2) enabling cross-region replication (if supported in your tenancy). Both methods are documented in the Oracle Cloud Infrastructure documentation under Block Volume Backup and Cross-Region Replication. Instance Principals, volume clones within the same region, or manually transferring raw volume data to Object Storage do not fulfill the DR replication requirements in a straightforward or supported manner.
- A. Correct.
Option 1 is correct. Creating backups of your volumes and copying them to the secondary region is a standard OCI feature for disaster recovery. You can configure scheduled backups and then manually or automatically copy them to another region.
- B. Incorrect.
Option 2 is incorrect. While Instance Principals provide authentication for instances to access OCI services, they do not automatically replicate attached volumes across regions. You still need to initiate and manage volume replication or backup copying.
- C. Incorrect.
Option 3 is incorrect. Cloning a volume is restricted to the same region. The clone remains in the primary region, so it does not provide protection if that region becomes unavailable.
- D. Correct.
Option 4 is correct. OCI supports cross-region replication for block volumes in selected regions. Using the Block Volume console or API, you can configure a live replication to another region, allowing near real-time DR protection.
- E. Incorrect.
Option 5 is incorrect. You cannot simply export a block or boot volume as an Object Storage image and upload it. OCI does not provide a direct mechanism to convert block volumes into object storage data for a DR scenario. You would normally copy actual backups to the secondary region.
