Sales Ops has requested the company’s Salesforce Admin to create a sales leader board showing all the closed worn opportunities by sales rep. What is the best approach to create this leader board?

Answer options:

A.Summary report with Metric component
B.Summary report with the Table component
C.Tabular report with the Chart component
D.Tabular report with the Table component

Correct Answer: B 
Use summary type for a report to show subtotals based on the value of a particular field or when you want to create a hierarchical list, such as all opportunities for your team, subtotaled by Stage and Owner. Summary reports with no groupings show as tabular reports on the report run page. 
Option A is incorrect because a metric component displays a single value in a dashboard just the value and its title. 
Options C and D are incorrect because tabular report simply consists of an ordered set of fields in columns, with each matching record listed in a row. While easy to set up, they can`t be used to create groups of data and there are limits on how you can use them in dashboards
