When a Custom Connector Is Truly Required in Power Automate
Short answer
B Building a custom connector for SharePoint Online lists is unnecessary because the standard SharePoint connector already retrieves that data.
Question
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
A company integrates external systems into Power Automate by using cloud flows.
The company must connect to external services with different characteristics and determine whether a custom connector is required.
You need to propose a solution to meet the requirements.
Solution: Create a custom connector to retrieve data from SharePoint Online lists.
Does the solution meet the goal?
Key Takeaways
The question asks whether a custom connector is required, not whether it would work — the trap is choosing Yes for SharePoint Online, which already has a built-in connector.
This AB-410 series question tests whether a custom connector is required to read SharePoint Online lists from a cloud flow. Because Power Automate includes a standard SharePoint connector, the proposed custom connector does not meet the goal, so the answer is B (No).
Common mistake: Answering A (Yes) because a custom connector can technically retrieve SharePoint list data; the goal is necessity, and the standard SharePoint connector already covers it.
Expert Analysis
Reading the qualifier The series preamble tells you the goal: connect to external services "with different characteristics" and determine whether a custom connector is required. So the test is not "does a custom connector work?" but "is a custom connector necessary for this particular service?" The proposed solution commits to building a custom connector for one specific system, so you must judge necessity, not feasibility.
SharePoint Online already has a built-in connector Power Automate ships with a standard SharePoint connector that exposes the actions this scenario needs — Get items, Get item, Get files, and so on — against SharePoint Online lists. Because the service is already supported out of the box, writing a custom connector for it adds needless maintenance, OpenAPI definition work, and authentication configuration while delivering no capability the standard connector lacks. Option A (Yes) therefore fails: the solution does not answer the underlying question of whether a custom connector is required.
What the answer must be Since a custom connector is not required for SharePoint Online, the proposed solution does not meet the goal, so the correct answer is B (No).
How this pattern plays out in the rest of the series Expect sibling questions where the target is an internal or legacy service with no standard connector — for example an on-premises SOAP endpoint or an undocumented API. There, a custom connector is required, and the answer flips to Yes. The trap in this question is assuming that because custom connectors are powerful, they are always the right tool. In Power Platform doctrine, the decision rule is: use the standard connector if one exists; build a custom connector only when no standard or certified connector covers the service.

Exam Strategy
In series-based yes/no questions, rewrite the goal as a decision rule — here, "is a custom connector required?" — then test the proposed solution against that rule rather than against technical feasibility. For each external system named, ask first whether a standard or certified connector already exists in Power Automate; if it does, any custom-connector answer is No. Reserve Yes for services with no out-of-the-box connector, such as internal or undocumented APIs.
