Question

A company plans to create a canvas app that connects to three databases with different proprietary database formats. What is the minimum number of connectors required?

Options

Explanation

The minimum number of connectors required is 1. A single custom connector can be built to expose a unified API (such as a middleware or API gateway) that internally routes to all three proprietary databases. Power Apps connects to this one endpoint regardless of how many backends exist behind it. Zero connectors (A) is impossible because some integration layer is always needed. While three separate connectors (D) is a valid architecture, the question asks for the minimum, so a single aggregating custom connector satisfies the requirement.
