Exam 1z0-997-22 topic 1 question 37 discussion

Actual exam question from Oracle's 1z0-997-22
Question #: 37
Topic #: 1
[All 1z0-997-22 Questions]

You are responsible for a web application deployed on a set of compute VM instances in Oracle Cloud Infrastructure (OCI). Your application stores data on block volumes.
In production, the business requirement is a Recovery Point Objective (RPO) of two hours and that data should be recoverable in case of a regional failure.
How would you meet the RPO requirement in the event of a failure?

  • A. Create a user-defined storage backup policy and attach a schedule of type "Hourly" and automatically copy to another region. Apply this policy to a volume group containing the block volumes.
  • B. Store hourly block volume backups to an NVMe device attached to a compute instance in a different Availability Domain (AD).
  • C. Configure your application to use synchronous primary-secondary data replication between ADs.
  • D. Set up cross-region volume replication to replicate the block volumes to a different OCI region.

Replicating a Volume The Block Volume service provides you with the capability to perform ongoing automatic asynchronous replication of block volumes, boot volumes, and volume groups to other regions and availability domains. There are two types of replication: Cross region, for replication between regions. Cross availability domain, for replication between availability domains within the same region. en you enable replication for a volume or volume group, the process includes an initial sync of the data from the source to the replica. Depending on volume size and amount of data written to volumes, this sync can take hours. After the initial synchronization process is complete, the replication process is continuous, with the typical Recovery Point Object (RPO) target rate being less than thirty minutes for replication across regions, however the RPO can vary.
