AB-900 Questions and Answers

The correct answers are A and D because Microsoft Entra Identity Secure Score is based on identity security recommendations, and Microsoft Learn specifically lists recommendations such as “Designate more than one Global Administrator” and “Do not expire passwords.” That means the number of global administrators in the tenant and whether password expiration is disabled directly influence the Identity Secure Score. Microsoft also notes that the score measures how closely an organization aligns with Microsoft’s recommended identity security best practices.

Option B is incorrect because SharePoint site permissions are related to SharePoint and Microsoft 365 workload permissions, not to the Entra identity-focused scoring model. Option C is incorrect because user location may be evaluated in Conditional Access and Zero Trust scenarios, but it is not itself listed as a direct Identity Secure Score factor in the Microsoft Entra recommendations referenced by Microsoft Learn. Identity Secure Score is driven by tracked identity recommendations and security configurations, not by simple geographic placement of users.

The correct selections are Yes, Yes, Yes . For statement 1, Microsoft Support explains that if you are not a site owner, you might still be able to invite other people to the site , although the invitation can generate an access request that a site owner approves or declines. Microsoft also states that site users have the opportunity to invite other people to collaborate on sites , unless that feature is disabled. That makes the statement true.

For statement 2, Microsoft Learn states that in SharePoint you can give people permissions to a site by adding individual users, security groups, or Microsoft 365 groups to one of the three SharePoint groups, including the Members group. That directly supports the statement.

For statement 3, Microsoft documents that site ownership and membership can be managed by adding or removing owners, members, site owners, site members, and site visitors . For group-connected sites, Microsoft also documents that owners can manage group ownership and remove owner status. Therefore, a site owner can remove another site owner, provided at least one owner remains.

The correct answer is Require multifactor authentication for administrative roles . In the exhibit, each recommendation shows its available Secure Score points . The listed values are 1/1 for Use least privileged administrative roles , 8/8 for Do not expire passwords , 0.73/8 for Enable policy to block legacy authentication , and 0/10 for Require multifactor authentication for administrative roles . Because 10 points is the highest value among the options shown, resolving that recommendation would improve the Identity Secure Score the most.

Microsoft Learn explains that Identity Secure Score in Microsoft Entra is based on Microsoft security recommendations, and each recommendation contributes a specific number of points depending on its impact and implementation state. Recommendations related to administrator protection are especially important because privileged accounts are high-value attack targets. Microsoft also emphasizes multifactor authentication for admin roles as a core identity security best practice. Therefore, both from the screenshot and from Microsoft’s identity guidance, the recommendation with the greatest score improvement is Require multifactor authentication for administrative roles .

The correct answer is C. the code interpreter capability . Microsoft Learn states that the code interpreter capability for Microsoft 365 Copilot declarative agents allows the agent to generate and execute Python code to analyze data and generate visualizations . Microsoft’s agent schema documentation explicitly describes Code Interpreter as a capability used to solve complex math problems, analyze data, and generate visualizations. That directly matches the requirement to create charts and visualizations from a Microsoft Excel workbook .

Microsoft documentation also explains that code interpreter supports working with Excel files and is used for scenarios such as data analysis , statistical computations , and generating charts . This makes it the correct configuration for an agent that must reason over workbook data and produce chart-based outputs. By contrast, the image generator capability is for creating images, not for analyzing workbook data. The Scrum Assistant and Customer Insights Assistant options are templates, not the specific technical capability required to read data and build charts from an Excel workbook.

The correct selections are No, Yes, No . Microsoft defines Zero Trust as a security strategy and explicitly states that it isn’t a product or a service . Instead, it is an approach based on principles such as verify explicitly , use least privilege access , and assume breach . That makes statement 2 true.

Statement 1 is false because Zero Trust does not require an Azure subscription. Microsoft provides Zero Trust guidance across many environments, including Microsoft 365, Copilot, Azure, and hybrid scenarios. It is a strategy that can be implemented with different technologies and is not dependent on owning Azure specifically.

Statement 3 is also false because there is no single switch in the Microsoft 365 admin center to “enable Zero Trust” for an organization. Microsoft’s documentation presents Zero Trust as a set of policies, configurations, and deployment steps across services such as Microsoft Entra, Intune, Defender, and Microsoft 365 workloads, not as one admin-center toggle.

The correct selections are The Microsoft 365 admin center and A billing policy . Microsoft documents that Microsoft 365 Copilot pay-as-you-go is administered in the Microsoft 365 admin center , specifically under Copilot > Billing & usage , where admins create and manage billing policies . Microsoft explains that a billing policy defines the billing infrastructure for pay-as-you-go, including the Azure subscription and the set of users covered by that policy. That user scoping is what allows organizations to separate usage and spending by groups such as departments.

Microsoft also documents that billing policies support budgets , spending views , and monitoring current expenses for services linked to the policy. This supports the requirement for greater visibility into Copilot usage costs and forecasting departmental spending. By assigning different departments to different billing policies, the organization can track Copilot costs by department. The other listed features do not fit: auto-claim policy is unrelated to cost tracking, and Copilot connector is for external data grounding, not billing segmentation.

The correct answer is A . Microsoft Learn defines Zero Trust as a security strategy built on the principles verify explicitly , use least privilege access , and assume breach . Microsoft also summarizes Zero Trust as a model that assumes breach and verifies every request , rather than trusting users, devices, or traffic simply because they originate from inside the corporate network. This is the key reason option A is correct. Under Zero Trust, every access request should be evaluated continuously using available signals such as identity, device state, location, service, and risk.

Option B is incorrect because improving user experience is not the defining principle of Zero Trust. Option C is incorrect because Zero Trust requires ongoing review and adjustment of permissions, especially through least privilege and risk-based access. Option D is incorrect because Zero Trust explicitly rejects implicit trust based on network location. Microsoft states that organizations should reduce reliance on the traditional idea that anything on the internal network is automatically safe or trustworthy.
