Which of the following is NOT a component of a custom report card?

A custom report card in Tenable Security Center is designed to summarize and present key data insights in a way that is tailored to the specific needs of the user or organization. The critical components of a custom report card typically include the name, which identifies the report; a description that outlines the purpose or scope of the report; and focus range, which specifies the particular areas or types of data being concentrated on.

The time frame, on the other hand, does not form an inherent component of the report card itself in terms of its core structure. While a time frame is indeed important for analytics and data interpretation, it is often considered as a separate parameter that can be applied to the data being reported rather than a fundamental aspect that shapes the report card's identity. Thus, the correct answer highlights that time frame is not a structural component of a custom report card.
