Quick Answer
The answer is the HTTP with Azure AD connector. This connector is the correct choice because it is designed to call any REST API while supporting Azure Active Directory authentication, which is essential for securely connecting to a legacy system that exposes a REST API. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of which connector to use when no prebuilt connector exists for a custom or legacy API. A common trap is confusing the HTTP with Azure AD connector with the generic HTTP connector, but the key difference is that the Azure AD version provides enterprise-grade authentication, making it the right fit for secure data access and updates. Remember, if you need to call a REST API with authentication, think “HTTP with Azure AD” — it’s your universal bridge for custom APIs.
This PL-900 practice question tests your understanding of demonstrate the capabilities of power apps. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has a legacy system that exposes a REST API. They want to build a Power App that displays data from this API and allows users to update records. Which connector should they use?
HTTP with Azure AD connector
Allows calling any REST API with Azure AD authentication.
Office 365 Users connector
Why wrong: Used for user profile data, not custom APIs.
SQL Server connector
Why wrong: Used for SQL databases, not REST APIs.
SharePoint connector
Why wrong: Only works with SharePoint data.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
HTTP with Azure AD connector
Option B is correct because the HTTP with Azure AD connector can call any REST API and supports authentication. Option A is wrong because SharePoint connector is for SharePoint lists. Option C is wrong because SQL Server connector is for SQL databases. Option D is wrong because Office 365 Users connector is for user profiles, not custom APIs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
