How should the developer design the Account Marker Layer to meet this requirement?

B . On the Related List Tab, choose "Opportunities’" from the "Add New" drop down and increment the Display counter to "5".
C . Use "Filter by Activity’ to limit the markers to Accounts with 5 opportunities or more.
D . Be sure that Opportunities are included in the Cross Object Filter options on the Filters tab.

Answer: B

Explanation:

To see the five most recent Opportunities when a Sales Rep selects a pin from an Account Marker Layer, the developer should use the Related List Tab on the Marker Layer configuration. This tab allows the developer to add related objects to the marker layer and display them as a list when a pin is clicked. The developer can choose “Opportunities” from the “Add New” drop down and increment the Display counter to “5” to show only the five most recent Opportunities. The Related List Tab is explained in the Explore Salesforce Maps on Desktop unit.
