Which of the following is NOT a usage type for CPM?

In the context of CyberArk's Central Password Manager (CPM), the primary function is to manage and secure credentials used for different types of applications and systems. The recognized usage types for CPM include categories like Windows Services, Database Strings, and IIS Application Pools, each of which involves automated password management for specific system functionalities and services.

Windows Services and IIS Application Pools are directly related to managing credentials that allow these services to operate securely. Database Strings refer to the connection strings that contain credentials necessary to access databases, again highlighting the critical nature of password management in database interactions.

Application Code, however, does not fall into the recognized categories of CPM usage types. While credentials are certainly used in application code, the management of those credentials is not typically handled by CPM directly. Instead, developers are encouraged to use secure coding practices and other solutions to handle passwords and keys within application code itself, rather than relying on CPM for managing these credentials. This distinction clarifies why "Application Code" is the answer that does not represent a valid usage type for CPM.
