Which two components will properly populate the grand total for a dashboard using a custom report?

To properly populate the grand total for a dashboard using a custom report, the metric is the most appropriate choice. Metrics are specifically designed to display key performance indicators (KPIs) and aggregate values such as totals, averages, or counts, allowing for a succinct overview of critical data points. When used on a dashboard, metrics can summarize large sets of data into a single, easily interpretable value, making them ideal for showcasing grand totals.

In contrast, the other components serve different purposes. Tables organize data in a structured format, displaying multiple rows and columns of information, but they do not inherently represent a single cumulative figure or grand total. Gauges visualize progress towards a particular goal or target but are not typically used to represent an aggregate total. Charts, while effective for presenting trends or comparisons across datasets, focus on visualizing relationships rather than providing a singular grand total. Therefore, metrics are the best tools for accurately displaying grand totals in a dashboard setting.
