The AI agrees with the suggested answer A (Master Policy).
Reasoning: The Master Policy in CyberArk is the central location for defining global password policies, including password rotation requirements. Setting the password rotation period in the Master Policy ensures that it applies to all users and Safes within the environment, unless overridden by more specific policies. This aligns with the requirement of setting a global password rotation policy for all passwords.
Reasons for not choosing other options:

B. Safe Templates: Safe Templates are used to define the structure and initial settings of new Safes, but they do not enforce global password policies.
C. PVWAConfig.xml: PVWAConfig.xml file is used to configure the Password Vault Web Access (PVWA) component, not for setting password policies.
D. Platform Configuration: While Platform Configuration is important for defining how CyberArk manages accounts on different target systems, it doesn't primarily control the global password rotation policy. Password rotation at the platform level is more about how passwords are changed on the target system itself and less about when users are forced to change their passwords in CyberArk.

Based on CyberArk documentation and best practices, the Master Policy is the correct place to configure the global password rotation requirement.

The information presented aligns with standard CyberArk configurations for implementing organization-wide password policies.

Answer: A. Master Policy

This topic doesn't discuss the configuration settings of PVWAConfig.xml file, Platform Configuration, and Safe Templates, so I can not provide the comparison of each choice.
