An administrator is asked to report on the conversion rate of Leads to Opportunities by lead source. Which report type should be used?
Leads with Converted Lead Information joins each converted lead to its resulting opportunity, exposing both the originating lead source and the conversion outcome in one dataset. That direct lead-to-opportunity linkage satisfies the stem's requirement to calculate conversion rate by lead source, which separate lead and opportunity reports cannot correlate.
Why this answer
The 'Leads with Converted Lead Information' report type is specifically designed to report on leads and includes fields from the converted Account, Contact, and Opportunity records. This allows an admin to calculate conversion rates by grouping on Lead Source and comparing total leads to converted leads. It is the standard report type for lead conversion analysis because it joins lead data with post-conversion data.
Exam trap
The trap here is confusing lead history tracking (which shows field changes) with conversion reporting; candidates often pick 'Lead History Reports' thinking it captures conversion, but it only tracks field audit history.
How to eliminate wrong answers
Option A is wrong because 'Campaigns with Converted Leads' focuses on campaign membership and converted leads, not on lead source conversion rates across all leads. Option C is wrong because Lead History Reports track field change history (e.g., status changes) but do not provide conversion linkage to opportunities. Option D is wrong because 'Opportunities with Leads' is not a standard report type and would not correctly represent the lead-to-opportunity conversion funnel by source.
