To support a fault-tolerant and high-availability architecture, which file needs to be changed on the PVWA to enable communication with the Primary Vault and Satellite Vaults?

The file that needs to be modified on the Password Vault Web Access (PVWA) to enable communication with both the Primary Vault and Satellite Vaults is the Vault.ini file. This file is critical because it contains configuration settings related to the vault connection parameters. By adjusting these parameters, you can ensure that the PVWA can connect reliably to the proper vaults within a fault-tolerant and high-availability architecture.

This architecture typically involves multiple vaults to enhance reliability and minimize downtime. The settings in the Vault.ini file play a crucial role in determining how the PVWA identifies and communicates with these vaults. Ensuring that the correct endpoints and settings are reflected in this configuration file is fundamental for maintaining seamless operations and synchronization between the Primary Vault and any Satellite Vaults.

Other files mentioned in the choices serve different purposes in the CyberArk environment. For instance, dbparm.ini is primarily used for database-related configurations, and cpm.ini pertains to the Central Password Manager settings. Meanwhile, padr.ini is associated with the management of privileged account discovery settings. Hence, while these files are important in their respective functionalities, they do not facilitate communication with the vaults in the context of high availability and fault tolerance.
