Nutanix documentation for multisite disaster recovery states that a protection policy can include multiple replication schedules across up to three different recovery clusters, and Nutanix also documents the ability to configure multisite replication schedules for up to three recovery clusters with different schedules. That means a source site can protect workloads to multiple destinations without requiring separate, duplicated protection policies for each site. Given the options, the most efficient approach is therefore one protection policy from the source cluster covering all three sites, which is option D.
The answer choices that create multiple separate protection policies are less efficient and introduce avoidable administrative duplication. Cloning policies across sites also misses the point of Nutanix's native multisite capability. Even though the sites are managed by different Prism Central instances, Nutanix documents DR support between clusters registered to different Prism Central instances as well. So the most scalable and documentation-aligned answer is D.

In Nutanix PD-based disaster recovery, when the source storage container name and the destination storage container name are different, the administrator must explicitly configure a vStore mapping. Nutanix documentation says that each vStores entry maps a local source storage container to a remote target storage container. Nutanix also documents that if you want replication from a local vStore to a remote vStore with different names, you provide the mapping between the local and target containers. That is exactly what this question is asking: source container Marketing, destination container Backups, and replication must know how those two names correspond. ( Nutanix Portal ) The other choices do not control storage-container placement for replicated data. Network mapping is about network connectivity for failover or recovery testing, not where the storage data lands. Network compression is unrelated to container targeting. vStore PD is not the Nutanix feature name that solves this requirement.
Nutanix's own remote-container best-practice guidance recommends establishing vStore mappings so the target container is deterministic and properly aligned to the protection design. Therefore, the correct and authentic Nutanix answer is C. vStore mapping. ( Nutanix Portal )

Nutanix documentation for Prism Central backup and restore repeatedly references NCM Self-Service as part of the Prism Central backup and recovery context. Nutanix specifically notes considerations for protecting and restoring NCM Self-Service-related entities when Prism Central is backed up and restored. That makes C the correct answer.
The other options do not fit the documented Prism Central backup scope in the same way. "Objects data" refers to data in the object store itself, not the platform service configuration protected as part of Prism Central backup workflows. LCM is a management service, but Nutanix does not present it as the answer to this specific question. "NUS" is not the documented backup-scope answer here. Since Nutanix explicitly calls out NCM Self-Service in PC backup and restore considerations, C is the authentic choice.

For a standard AHV cluster deployment, each node typically requires one IP for the hypervisor host, one for the Controller VM (CVM), and one for IPMI or management access. Nutanix cluster-creation and expansion documentation repeatedly references entering host, CVM, and IPMI addresses for each node. If the administrator also wants a cluster virtual IP, that adds one additional IP for the cluster VIP. This results in three IPs per node plus one VIP, which is option C. ( Nutanix ) The answer choices with four IPs per node overstate the standard requirement, while the two-VIP choices add an extra VIP not requested in the question. Nutanix documentation for cluster details also distinguishes the per-node addresses from the optional virtual IP used for cluster access. So the clean way to think about this is:
per node = host + CVM + IPMI, plus one shared VIP for the cluster. That aligns exactly with C. ( Nutanix )

Here the uploaded answer key says D, but current Nutanix documentation says that when a cluster is created, the system automatically creates one storage pool and one storage container. Nutanix also documents built-in containers such as NutanixManagementShare and SelfServiceContainer in later feature contexts, which is likely why older or exam-bank wording can become confusing. However, the direct cluster-creation documentation states one storage pool and one storage container are automatically created at cluster creation time. That means none of the options perfectly reflects the current documentation.
Because your source file's answer key marks D, I am preserving that exam-bank answer here, but I want to be explicit that official current Nutanix documentation does not match these choices exactly. For a strict real- world Nutanix administration answer, I would state: one storage pool and one storage container are created automatically. For consistency with your question set, the preserved answer remains D, but this is one of the items I would flag for correction in a final polished study guide.
