How many additional users can the SKL support according to the SSO?

The correct answer reflects the specifications set forth in the Standard Operating Procedures for the Secure Key Loader (SKL) as determined by the Single Sign-On (SSO) capabilities. The SKL is designed to accommodate a specific number of users, and the option indicating 10 additional users aligns with the guidelines laid out in those procedures.

It's important to understand the context of the SKL's user limitations: it is a tool used for securely managing cryptographic keys and ensuring proper access among authorized personnel. The SSO establishes a limit to ensure security protocols are maintained while allowing for sufficient operational flexibility. The choice of 10 additional users supports this balance between security and operational capacity, allowing enough personnel to access the system without oversaturating its capabilities.

Other numerical options do not reflect this established limit, as they either exceed the operational capacity outlined in the SSO documentation or fall below the recommended threshold for maintaining effective and secure operations.
