Which of the following statements are true regarding the grouping of elements in SteelCentral Portal?

Grouping in SteelCentral Portal is a foundational feature for organizing and analyzing performance data. It allows administrators to combine multiple, related configuration items (such as servers, applications, or network devices) into a single logical entity. This grouping facilitates the aggregation of performance metrics (A), enables the display of this combined data in a single dashboard widget or report visualization (B), and supports the creation of nested, parent-child hierarchies for data roll-ups and drill-downs (C). Because all listed statements accurately describe core functionalities of element grouping within the platform, "All of the above" is the most comprehensive and correct answer.

A. Allows aggregation of multiple elements: This statement is true, but it is not the only function of grouping. It is an incomplete answer.

B. Displays multiple elements in a single visualization: This is also a true statement and a primary benefit of grouping, but it is not the sole purpose.

C. Creates a parent-child hierarchy using roll ups: This is another true statement describing the advanced capability of nested groups, but it does not cover all aspects.
