Which services should be running on the DR vault of a CyberArk Disaster Recovery (DR) solution?

In a CyberArk Disaster Recovery solution, the services that should be running on the DR vault are specifically tailored to ensure that the vault can function effectively in a recovery scenario. The first option, which includes the CyberArk Vault Disaster Recovery (DR) service and the PrivateArk Database, is essential because it allows for the replicated storage and management of sensitive information.

The CyberArk Vault Disaster Recovery (DR) service is responsible for handling the disaster recovery operations, ensuring that the primary vault's data is available and consistent in the event of a failure. Meanwhile, the PrivateArk Database is critical since it stores the vault's core data, including credentials and permissions. Without these services running, the DR vault would not be able to perform its primary function of securing and managing privileged accounts during a disaster.

The other options focus on various components that might be pertinent in other contexts, such as high availability or general vault management, but do not encompass the specific requirements and roles necessary for the effective operation of a DR vault. Thus, the first option accurately reflects the necessary services for a successful CyberArk Disaster Recovery implementation.
