Which file must be edited to include peer node information?

The correct choice is based on the specific role of the ClusterVault.ini file in a CyberArk environment. This file is essential for configuring the settings related to cluster nodes within a Vault environment. When deploying a clustered Vault, it is crucial to define the peer nodes that the Vault will communicate with to maintain synchronization and ensure high availability.

The ClusterVault.ini file contains the necessary parameters to identify and manage the cluster topology, including details about the peer nodes, their roles, and how they connect to the primary node. Editing this file correctly allows the CyberArk system to recognize and interact with other nodes in the cluster effectively, ensuring that operations and data remain consistent across all instances.

In contrast, dbparm.ini typically contains database parameters, service.config is used for configuring service-related settings, and node.config generally handles configurations specific to individual nodes rather than cluster-wide settings. Thus, while those files are important for various settings and functions in the CyberArk architecture, they do not serve the specific purpose of including peer node information like the ClusterVault.ini file does.
