Correct answer: B
Explanation:
When you buy a Microsoft 365 for business subscription, you select a billing frequency. You can change how often you're billed for your subscription in the Microsoft 365 admin center.
A Cloud Services Provider (CSP) resells Microsoft services, handles billing, and provides support and additional services. This model offers flexibility and value-added services.
Microsoft accepts credit cards and debit cards as payment methods for the business products and services that you buy from us. In some cases, you can use a wire transfer to pay your invoice. How these payment methods are applied depends on the type of billing account that you have with us. For example, if you have a Microsoft Customer Agreement (MCA) billing account, you pay your bill with a billing profile that’s backed with a credit card, debit card, or wire transfer. If you have a Microsoft Online Subscription Agreement (MOSA), you pay your bill directly with a credit card or debit card.

A company is evaluating Microsoft 365 and Microsoft Entra solutions.
You need to describe the External Identities features in Microsoft Entra,
Match each External identity to its capability.
(To answer, move the appropriate External Identity from the column on the left to its capability on the right. You may use each External Identity once, more than once, or not at all. NOTE: Each correct match is worth one point.)

A | P1: B2C
P2: B2B collaboration |
B | P1: B2C
P2: B2C |
C | P1: B2B collaboration
P2: B2C |
D | P1: B2B collaboration
P2: B2B collaboration |
Correct answer: C
Explanation:
Microsoft Entra External ID includes collaboration capabilities that allow your workforce to work securely with business partners and guests. In your workforce tenant, you can use B2B collaboration to share your company's applications and services with guests, while maintaining control over your own corporate data. Work securely with external partners, even if they don't have Microsoft Entra ID or an IT department.
A simple invitation and redemption process lets partners use their own credentials to access your company's resources. You can also enable self-service sign-up user flows to let guests sign up for apps or resources themselves. Once the guest redeems their invitation or completes sign-up, they're represented in your directory as a user object. The user type for these B2B collaboration users is typically set to "guest" and their user principal name contains the #EXT# identifier.
Azure Active Directory B2C provides business-to-customer identity as a service. Your customers can use their preferred social, enterprise, or local account identities to get single sign-on access to your applications and APIs.
Azure AD B2C is a customer identity access management (CIAM) solution capable of supporting millions of users and billions of authentications per day. It takes care of the scaling and safety of the authentication platform, monitoring, and automatically handling threats like denial-of-service, password spray, or brute force attacks.
Azure AD B2C is built on the same technology as Microsoft Entra ID but for a different purpose and is a separate service. It allows businesses to build customer facing applications, and then allow anyone to sign up and sign in to those applications with no restrictions on user account.

The CSP informs you that the monthly uptime of your Microsoft 365 services for the previous month was 97%.
You need to determine the service credit that you should receive from Microsoft.
Which service credit percentage should you receive?

Service Credit is the percentage of the Applicable Service Fees credited to you following Microsoft’s claim approval. Credit requests are accepted only from CSP direct and indirect providers.
Downtime is any period of time when end users are unable to login to their instance.
Uptime Percentage: The Uptime Percentage is calculated using the following formula:

You need to recommend a solution.
Which tool should you use?

Power Apps is a suite of apps, services, and connectors, as well as a data platform, that provides a rapid development environment to build custom apps for your business needs. Using Power Apps, you can quickly build custom business apps that connect to your data stored either in the underlying data platform (Microsoft Dataverse) or in many online and on-premises data sources (such as SharePoint, Microsoft 365, Dynamics 365, SQL Server, and so on).
Apps built using Power Apps provide rich business logic and workflow capabilities to transform your manual business operations into digital, automated processes. What's more, apps built using Power Apps have a responsive design and can run seamlessly in browser and on mobile devices (phone or tablet). Power Apps "democratizes" the business-app-building experience by enabling users to create feature-rich, custom business apps without writing code.
Power Apps also provides an extensible platform that lets pro developers programmatically interact with data and metadata, apply business logic, create custom connectors, and integrate with external data.
Power Apps and Microsoft Copilot let you describe the app you want and AI designs it. Make edits, add automation, and write code—all with Copilot in Power Apps.
