What time measurement is used to define the clock skew tolerance in a Single Sign-On token configuration policy?

1. Milliseconds

2. Seconds

3. Minutes

4. Hours

The correct answer is: Milliseconds

The clock skew tolerance in a Single Sign-On (SSO) token configuration policy is defined in milliseconds. This level of granularity is crucial because SSO systems often operate in environments where timing discrepancies between different components (like authentication servers and client devices) can occur due to network latency or differences in time synchronization. Using milliseconds allows for a precise tolerance that ensures tokens are still considered valid even when there are minor discrepancies in system time, thereby improving the user experience by reducing the chances of authentication failures due to slight timing mismatches. Options that represent larger units, such as seconds, minutes, or hours, would not be suitable for a system that requires timely validation and may lead to user authentication issues if the tolerances are too lax. Therefore, the choice of milliseconds reflects the need for accurate and efficient handling of token validation in rapid transaction environments typical in modern IT infrastructures.
