The administrator can achieve this requirement by creating a bucket replication rule and setting the destination Objects instance. Bucket replication is a feature that allows administrators to replicate data from one bucket to another bucket on a different Objects instance for disaster recovery or data migration purposes.
Bucket replication can be configured with various parameters, such as replication mode, replication frequency, replication status, etc. Bucket replication can also replicate all versions of objects, including delete markers, which are special versions that indicate that an object has been deleted. By creating a bucket replication rule and setting the destination Objects instance, the administrator can replicate data from one Objects instance to another asynchronously, including all delete markers and versions. References: Nutanix Objects User Guide, page 19; Nutanix Objects Solution Guide, page 9 Nutanix Objects, part of Nutanix Unified Storage (NUS), supports replication of buckets between Object Store instances for disaster recovery (DR). The organization has two Objects instances across two sites, managed by the same Prism Central, and needs to replicate a bucket's data asynchronously, including delete marker versions, to the secondary site.
Analysis of Options:
* Option A (With Object Browser, upload the data at the destination site): Incorrect. The Object Browser is a UI tool in Nutanix Objects for managing buckets and objects, but it is not designed for replication. Manually uploading data to the destination site does not satisfy the requirement for asynchronous replication, nor does it handle delete marker versions automatically.
* Option B (Leverage the Objects Baseline Replication Tool from a Linux VM): Incorrect. The Objects Baseline Replication Tool is not a standard feature in Nutanix Objects documentation. While third-party tools or scripts might be used for manual replication, Nutanix provides a native solution for bucket replication, making this option unnecessary and incorrect for satisfying the requirement.
* Option C (Use a Protection Domain to replicate the Objects Volume Group): Incorrect. Protection Domains are used in Nutanix for protecting VMs and Volume Groups (block storage) via replication, but they do not apply to Nutanix Objects. Objects uses bucket replication rules for DR, not Protection Domains.
* Option D (Create a Bucket replication rule, set the destination Objects instance): Correct. Nutanix Objects supports bucket replication rules to replicate data between Object Store instances asynchronously. This feature allows the organization to replicate the bucket to the secondary site, including all versions (such as delete marker versions), as required. The replication rule can be configured in Prism Central, specifying the destination Object Store instance, and it supports asynchronous replication for DR purposes.
Why Option D?
Bucket replication in Nutanix Objects is the native mechanism for asynchronous replication between Object Store instances. It supports replicating all versions of objects, including delete marker versions (which indicate deleted objects in a versioned bucket), ensuring that the secondary site has a complete replica of the bucket for DR. Since both Object Store instances are managed by the same Prism Central, the administrator can easily create a replication rule to meet the requirement.

From the Nutanix Objects Administration Guide (available on the Nutanix Portal):
"Nutanix Objects supports asynchronous bucket replication for disaster recovery. To replicate a bucket to a secondary site, create a bucket replication rule in Prism Central, specifying the destination Object Store instance. The replication rule can be configured to include all versions, including delete marker versions, ensuring that the secondary site maintains a complete replica of the bucket for DR purposes."
